Description

An exhaust air blowing means for ventilating the exhaust air path of the discharge air discharged outside the air-conditioning target space;
A humidity control body arranged so that a part is located in the air supply air passage and another part is located in the exhaust air air passage, and a portion of the humidity control body located in the air supply air passage and the exhaust Humidity control means comprising humidity control drive means for driving and rotating the humidity control body so as to change the portion positioned in the air path with rotation;
A heating means that heats the air that flows in the ventilation direction upper side of the humidity control body in the supply air path or in the ventilation direction upper side of the humidity control body in the exhaust air path;
The present invention relates to an air conditioner provided with sensible heat exchange means including a sensible heat exchanger arranged so that a part is located in the supply air passage and another part is located in the exhaust air passage.

  Such an air conditioner performs a humidifying operation in which supply air is humidified by the humidity control means and supplied to the air conditioning target space, or a dehumidification operation in which the supply air is dehumidified by the humidity control means and supplied to the air conditioning target space. In this way, the air-conditioning target space is humidified or dehumidified.

In other words, when performing the humidification operation, the heating means is provided at a location on the upper side of the ventilation direction with respect to the humidity control body in the air supply air passage, and a part of the sensible heat exchanger is more than the heating means in the air supply air passage. It arrange | positions so that it may be located in the ventilation direction upper side location, and may be located in the ventilation direction lower side location rather than the humidity control body in an exhaust air path.
Then, by rotating the humidity control body and operating the heating means by heating, the supply air is heated by sensible heat exchange with the discharge air by passing through the sensible heat exchanger, and further the heating After heating by passing the means, the humidity control body is passed and humidified, and supplied to the air-conditioning target space.

Then, by rotating the humidity control body and operating the heating means by heating, the supply air is dehumidified by passing through the humidity control body, and further passing through the sensible heat exchanger for discharge. It cools by sensible heat exchange with air, and supplies it to air-conditioning object space (for example, refer patent document 1).

JP 2003-4255 A

By the way, when air-conditioning the air-conditioning target space, there may be a case where an operation that only causes heat exchange between the supply air and the discharge air is desired in addition to the humidification operation or the dehumidification operation.
For example, when the first type ventilation is performed by supplying the outside air as supply air to the air-conditioning target space and discharging the air in the air-conditioning target space as the discharge air outside the air-conditioning target space, this air conditioning is performed in the winter season or the like. When the air conditioning target space is heated by an air conditioner different from the device and the humidity of the air conditioning target space is in a comfortable state, heating is performed so that heat is exchanged between the supply air and the discharge air. It becomes possible to reduce the energy consumption related to.
In addition, when the air-conditioning space is cooled by an air-conditioning device other than this air-conditioning device, such as in summer, when the humidity of the air-conditioning space is comfortable, heat exchange is performed between supply air and discharge air. When the operation is performed, it is possible to reduce energy consumption related to cooling.

  And in the conventional air conditioner, in order to perform an operation of only exchanging heat between the supply air and the discharge air, the humidity control body is stopped and the heating means is stopped, and the sensible heat exchanger Thus, the sensible heat can be exchanged between the supply air and the discharge air. Incidentally, the sensible heat that drives and rotates the sensible heat exchanger so that the sensible heat exchange means changes the portion located in the supply air passage and the portion located in the exhaust air passage in the sensible heat exchanger with rotation. In some cases, a replacement type drive unit is provided and a rotary type is configured. In this case, the amount of sensible heat exchange between the supply air and the discharge air can be further increased.

However, the enthalpy exchange efficiency between the supply air and the discharge air cannot be increased sufficiently only by exchanging the sensible heat between the supply air and the discharge air by the sensible heat exchanger, For example, energy consumption related to heating and cooling could not be reduced sufficiently.
In order to increase the enthalpy exchange efficiency between the supply air and the discharge air, it is conceivable to enlarge the sensible heat exchanger of the existing sensible heat exchange means or increase the number of sensible heat exchange means. However, an air conditioner will be enlarged.

  The present invention has been made in view of such circumstances, and its purpose is to operate so as to increase the enthalpy exchange efficiency between supply air and discharge air while avoiding an increase in the size of the air conditioner. It is to provide an air conditioner to obtain.

The air conditioner of the present invention includes an air supply air blowing means that ventilates an air supply air passage for supply air supplied to the air conditioning target space,
An exhaust air blowing means for ventilating the exhaust air path of the discharge air discharged outside the air-conditioning target space;
A humidity control body arranged so that a part is located in the air supply air passage and another part is located in the exhaust air air passage, and a portion of the humidity control body located in the air supply air passage and the exhaust Humidity control means comprising humidity control drive means for driving and rotating the humidity control body so as to change the portion positioned in the air path with rotation;
A heating means that heats the air that flows in the ventilation direction upper side of the humidity control body in the supply air path or in the ventilation direction upper side of the humidity control body in the exhaust air path;
Sensible heat exchange means including a sensible heat exchanger arranged so that a part is located in the supply air path and another part is located in the exhaust air path,
The first characteristic configuration is configured such that the humidity control means is capable of changing and adjusting the drive rotation speed of the humidity control body,
The heating means is configured to be switchable between a heating operation state and a heating stop state.

  That is, the humidity control means is configured to be able to change and adjust the drive rotation speed of the humidity control body, and the heating means is configured to be switchable between a heating operation state and a heating stop state, so that the humidity control body can be supplied. In addition to the humidification operation or dehumidification operation that is driven to rotate at a driving rotation speed suitable for humidification or dehumidification of air and the heating means is in a heating action state, the humidity control body is faster than the humidification operation or the dehumidification operation. It is possible to perform an operation (hereinafter sometimes referred to as a total heat / sensible heat exchange operation) that is rotationally driven at a driving rotational speed and is performed with the heating means in a heating stopped state.

In other words, when supply air and discharge air are passed through a rotationally driven humidity control body, the sensible heat is exchanged between the supply air and the discharge air due to the temperature difference between the supply air and the discharge air. In addition, the latent heat can be exchanged between the supply air and the discharge air due to the humidity difference, and the total heat can be exchanged between the supply air and the discharge air. The inventor of the present invention has earnestly studied, and by increasing the driving rotational speed of the humidity control body, the total heat exchange amount between the supply air and the discharge air passing therethrough in the humidity control body It was found that it is possible to increase a lot.
Considering this, since the speed at which the humidity control body moves through the air supply and exhaust air passages increases by increasing the drive rotation speed of the humidity control body, the humidity control body and the supply air and exhaust air The sensible heat and latent heat exchange between the sensible heat and the latent air can be quickly moved between the supply air and the discharge air in the humidity control body. Thus, the total heat exchange amount between the supply air and the discharge air in the humidity control body can be increased.

When the total heat / sensible heat exchange operation is performed as described above, in the humidity control body, the total heat exchange is performed in a state where the total heat exchange amount is increased between the supply air and the discharge air. In the sensible heat exchanger, sensible heat exchange can be performed between the supply air and the discharge air, so that the enthalpy exchange efficiency between the supply air and the discharge air is sufficiently increased. For example, the energy consumed for heating and cooling can be sufficiently reduced.
Accordingly, it is possible to provide an air conditioner that can be operated to increase the enthalpy exchange efficiency between the supply air and the discharge air while avoiding an increase in the size of the air conditioner.

In addition to the first feature configuration, the second feature configuration is
The heating means is provided at a location on the upper side in the ventilation direction with respect to the humidity control body in the supply air passage, and a part of the sensible heat exchanger is on the upper side in the ventilation direction with respect to the heating means in the supply air passage. After being heated by the sensible heat exchanging means, the air is disposed at a location and the other part is positioned at a location on the lower side in the ventilation direction than the humidity control body in the exhaust air passage. And configured to humidify by the humidity control means,
A supply guide for guiding a part of the exhaust air that has passed through the humidity control body and before passing through the sensible heat exchanger to a location between the sensible heat exchanger and the heating means in the supply air passage. It is characterized in that a wind part is provided.

That is, a part of the discharge air that has passed through the humidity control body and before passing through the sensible heat exchanger is guided to a location between the sensible heat exchanger and the heating means in the supply air passage through the supply air guide section. While being discharged, the discharge air passes through the humidity control body and the sensible heat exchanger in order, and the supply air passes through the sensible heat exchanger, the heating means, and the humidity control body in order.
In other words, when the heating means is in the heating action state, when the exhaust air passes through the humidity control body, water vapor in the exhaust air is absorbed by the humidity control body and is heated by the condensation heat, and the exhaust air is discharged. When the air passes through the sensible heat exchanger, the retained heat is given to the sensible heat exchanger to heat the sensible heat exchanger, and the supply air is heated by passing through the sensible heat exchanger, Since the air is heated by passing through the heating means and the supply air passes through the humidity control body, the humidification operation of humidifying the supply air can be performed.

Then, a part of the high-temperature exhaust air that has passed through the humidity control body and before passing through the sensible heat exchanger is led to a location between the sensible heat exchanger and the heating means in the supply air passage. Since it is mixed with air, the air volume of the supply air that passes through the humidity control body can be increased, and the air-conditioning target space can be humidified and heated more quickly. Further, it is possible to reduce the amount of energy required for heating the supply air by the heating means.
Therefore, in an air conditioner capable of humidification operation, it has become possible to improve the humidification and heating performance of the air-conditioning target space while reducing energy consumption.

In addition to the first feature configuration, the third feature configuration is
The heating means is provided at a location nearer to the ventilation direction than the humidity control body in the exhaust air passage, and a part of the sensible heat exchanger is lower in the ventilation direction than the humidity control body in the supply air passage. It is arranged to be located at a side location and the other part is located at a location closer to the ventilation direction than the heating means in the exhaust air passage, and after dehumidifying the supply air by the humidity control means, It is configured to cool with the sensible heat exchange means,
A discharge guide that guides a part of the supply air that has passed through the humidity control body and before passing through the sensible heat exchanger to a location between the sensible heat exchanger and the heating means in the exhaust air passage. It is characterized in that a wind part is provided.

That is, a part of the supply air that has passed through the humidity control body and before passing through the sensible heat exchanger is guided to a location between the sensible heat exchanger and the heating means in the exhaust air passage through the discharge wind guide section. While being discharged, the discharge air passes through the sensible heat exchanger, the heating means, and the humidity control body in order, and the supply air passes through the humidity control body and the sensible heat exchanger in order.
In other words, when the heating means is in the heating action state, the exhaust air is heated by absorbing the heat held by the sensible heat exchanger when passing through the sensible heat exchanger, and further passes through the heating means. When the exhaust air passes through the humidity control body, it is dehumidified from the humidity control body, and the supply air is dehumidified and heated by passing through the humidity control body, and the supply air is sensible heat exchanged. Since it cools by passing a body, the dehumidification driving | operation which dehumidifies supply air can be performed.

Then, a part of the high-temperature supply air that has passed through the humidity control body and before passing through the sensible heat exchanger is led to a location between the sensible heat exchanger and the heating means in the exhaust air passage. Since it is mixed with the air, the amount of moisture released from the humidity control body to the discharge air is increased by increasing the air volume and reducing the humidity of the discharge air before passing through the humidity control body. It is possible to improve the dehumidifying performance for dehumidifying.
Therefore, in the air conditioner capable of dehumidifying operation, the dehumidifying performance of the air-conditioning target space can be improved.

In addition to any of the first to third feature configurations described above, the fourth feature configuration is
The sensible heat that drives and rotates the sensible heat exchanger so that the sensible heat exchange means changes the portion located in the air supply air passage and the portion located in the exhaust air passage in the sensible heat exchanger with rotation. And a sensible heat exchange operation state in which the sensible heat exchange drive is driven and rotated by the sensible heat exchange drive means, and the sensible heat exchange body by the sensible heat exchange drive means. It is characterized in that it is configured to be switchable to a sensible heat exchange stop state in which the drive rotation is stopped.

That is, the sensible heat exchange means is operated in a sensible heat exchange operation state in which the sensible heat exchange driving means is driven to rotate the sensible heat exchange driving means, or the sensible heat exchange driving means is rotated by the sensible heat exchange driving means. It can be operated in a sensible heat exchange stop state to be stopped.
That is, when the operation of the humidity control drive means is stopped, the drive rotation of the humidity control body is stopped, and the heating means is in the heating stop state, the sensible heat exchange means is brought into the sensible heat exchange operation state. Sensible heat exchange operation is possible, in which the sensible heat exchanger only exchanges sensible heat with the exhaust air, and the humidity control drive is stopped to stop the rotation of the humidity control body. When the sensible heat exchange means is in the sensible heat exchange stopped state with the heating means in the heating stopped state, for example, in the case where the supply air is outside air and the discharge air is air in the air-conditioning target space, A normal ventilation operation in which the air-conditioning target space is ventilated without air conditioning becomes possible.
Further, when the dehumidifying operation is possible, the sensible heat exchanging means is driven while the humidity control body is rotated at a driving rotational speed suitable for dehumidification of the supply air and the heating means is in a heating action state. When the sensible heat exchange operation state is set, the dehumidifying operation can be performed, and when the sensible heat exchange unit is set to the sensible heat exchange stopped state, the drying operation capable of supplying high-temperature air with low humidity can be performed. Note that the drying operation is suitable for use in drying the air-conditioning target space, for example.
Therefore, in addition to the humidifying or dehumidifying operation and the total heat / sensible heat exchanging operation, the sensible heat exchanging operation in which only the sensible heat exchange between the supply air and the exhaust air is performed, and the air conditioning target space is not air-conditioned. It is also possible to switch to normal ventilation operation that ventilates, and if it is configured so that dehumidification operation is possible, it can also be switched to dry operation, so it is easy to use. It has become possible to further improve.

In addition to the fourth feature configuration, the fifth feature configuration includes:
The operation control means for controlling the operation of the humidity control means, the heating means and the sensible heat exchange means, as an operation mode, rotationally drives the humidity control body at a humidity control setting speed, and the heating means is in a heating action state. And a humidity control operation mode in which the sensible heat exchange means is in the sensible heat exchange operation state, the humidity control body is rotationally driven at a set speed for total heat exchange higher than the set speed for humidity control, and the heating means In the heating stop state and the sensible heat exchange means in the sensible heat exchange operation state, the total heat / sensible heat exchange operation mode, the drive rotation of the humidity control body is stopped, the heating means is set in the heating stop state, and the A sensible heat exchange operation mode in which the sensible heat exchange means is in the sensible heat exchange operation state, and the drive rotation of the humidity control body is stopped, the heating means is in a heating stop state, and the sensible heat exchange means is in the sensible heat Normal ventilation operation mode to stop replacement Of de, it characterized that it is configured to provide at least the humidity operation mode and the total heat-sensible heat exchanger operating mode.

  That is, the operation control means has at least the humidity adjustment operation mode and the total heat / sensible heat exchange among the humidity adjustment operation mode, the total heat / sensible heat exchange operation mode, the sensible heat exchange operation mode, and the normal ventilation operation mode. Since the operation mode is provided, the operation mode can be switched by a simple operation.

By the way, if the heating means is provided at the upper side in the ventilation direction than the humidity control body in the supply air path, the humidification operation can be executed as the humidity control operation, and the heating means is located at the upper side in the ventilation direction than the humidity control body in the exhaust air path. If it provides, dehumidification operation can be performed as humidity control operation.
Further, in the total heat / sensible heat exchange operation mode, as described above, the operation can be performed to increase the enthalpy exchange efficiency between the supply air and the discharge air.
Further, in the sensible heat exchange operation, the operation can be performed in a state in which the supply air and the discharge air are only subjected to sensible heat exchange.
Further, in normal ventilation operation, supply air is supplied to the air-conditioning target space without causing heat exchange between the supply air and the discharge air, and the discharge air is discharged outside the air-conditioning target space. Therefore, for example, when the supply air is the outside air and the discharge air is the air in the air-conditioning target space, the air-conditioning target space can be ventilated without air conditioning.
Accordingly, at least the humidity adjustment operation mode and the total heat / sensible heat exchange operation mode among the humidity adjustment operation mode, the total heat / sensible heat exchange operation mode, the sensible heat exchange operation mode, and the normal ventilation operation mode are set to, for example, the air-conditioning target space. Since it can be selected according to the air condition (for example, humidity or temperature) and executed by a simple operation, the usability can be further improved.

In addition to the fifth feature configuration, the sixth feature configuration is
The operation control means is detection information of each of the humidity detection means for detecting the humidity of the air-conditioning space and the outside air humidity detection means for detecting the humidity of the outside air, or the humidity detection means for the space, the outside air humidity detection means, It is characterized in that it is configured to select and execute an operation mode based on detection information of an in-space temperature detecting means for detecting the temperature of the air-conditioning target space and an outside air temperature detecting means for detecting the temperature of the outside air. To do.

  That is, the detection information of the humidity detection means in the space for detecting the humidity of the air-conditioning target space and the detection information of the outside air humidity detection means for detecting the humidity of the outside air, or the temperature detection in the space, the outdoor air humidity detection means, and the temperature of the air-conditioning target space are detected. Based on the detection information of each of the space temperature detection means and the outside air temperature detection means for detecting the temperature of the outside air, it is possible to obtain the air condition and the outside air condition of the air conditioning target space. It is possible to automatically select and execute an operation mode according to the air condition or the outside air condition.

  For example, when it is determined that it is preferable to humidify the air-conditioning target space according to the air condition of the air-conditioning target space or the outside air condition, the humidification operation as the humidity control operation is executed to dehumidify the air-conditioning target space. When preferable, when the dehumidifying operation as the humidity control operation is executed, the humidity of the air-conditioning target space can be made preferable.

  Also, depending on the air condition of the air-conditioning target space and the outside air condition, for example, when the air-conditioning target space is in a heated state and the air in the air-conditioning target space is determined to be appropriate humidity, When it is determined that the air in the air-conditioned space is in a suitable condition, the total heat / sensible heat exchange operation can be performed between the supply air and the discharge air. It becomes possible to increase the enthalpy exchange efficiency of the battery and reduce the energy consumption related to heating and cooling.

  Also, when the sensible heat exchange operation mode is provided as the operation mode, for example, when the supply air is outside air and the discharge air is air in the air-conditioning target space, the air condition in the air-conditioning target space is at an appropriate temperature. When the sensible heat exchange operation mode is executed when the outside air condition is determined to be appropriate humidity, the temperature and humidity of the air-conditioning target space should be made favorable while the air-conditioning target space is ventilated. Is possible.

Also, a normal ventilation operation mode is provided as an operation mode. For example, when the supply air is outside air and the discharge air is air inside the air-conditioning target space, it is determined that the outside air condition is appropriate temperature and humidity. Then, when the normal ventilation operation mode is executed, it is possible to make the temperature and humidity favorable while ventilating the air-conditioning target space.
Therefore, since the operation mode according to the air condition of the air-conditioning target space and the outside air condition is automatically selected and executed, the air conditioner can be operated more appropriately.

In addition to any of the first to sixth feature configurations described above, the seventh feature configuration is
The supply air is outside air, and the discharge air is air in an air-conditioning target space.

That is, outside air is passed through the supply air passage by the supply air blowing means and supplied to the air-conditioning target space as supply air, and air in the air-conditioning target space is passed through the exhaust air passage by the exhaust air blowing means and discharged air Therefore, the air-conditioning target space is ventilated by so-called first type ventilation.
Therefore, the effect by any of said 1st-6th characteristic structure can be achieved, performing 1st type ventilation.

In addition to any of the first to sixth feature configurations described above, the eighth feature configuration is
The supply air and the discharge air are outside air.

That is, the outside air is passed through the air supply air passage by the air supply and air supply means and supplied to the air-conditioning target space as supply air, and the outside air is passed through the exhaust air passage by the exhaust air blowing means and discharged to the outside as the discharge air. Since the air in the air-conditioning target space is naturally discharged to the outside by the forced supply of the outside air to the air-conditioning target space by such an air supply / air blowing means, the so-called second type ventilation causes the air-conditioning target The space is ventilated.
Therefore, the effect by any of said 1st-6th characteristic structure can be achieved, performing 2nd type ventilation.

In addition to any of the first to sixth feature configurations described above, the ninth feature configuration is
The supply air and the discharge air are air in an air-conditioning target space.

That is, air in the air-conditioning target space is passed through the air supply air passage by the air supply and blowing means and supplied to the air-conditioning target space as supply air, and air in the air-conditioning target space is passed through the exhaust air passage by the exhaust air blowing means. Then, the air is discharged to the outside as discharge air, and the outside air is naturally supplied to the air-conditioning target space by such forced exhaust of the air in the air-conditioning target space by the exhaust air blowing means, so-called third The air-conditioned space is ventilated by seed ventilation.
Therefore, the effect by any of said 1st-6th characteristic structure can be achieved, performing 3rd type ventilation.

In addition to any of the first to sixth feature configurations described above, the tenth feature configuration is
The supply air is air in an air-conditioning target space, and the discharge air is outside air.

That is, the air in the air-conditioning target space is passed through the air supply air passage by the air supply and blowing means and supplied to the air-conditioning target space as supply air, and the outside air is passed through the exhaust air passage by the exhaust air blowing means and discharged. Discharged to the outside.
That is, the air-conditioning target space is air-conditioned by circulating the air in the air-conditioning target space while air-conditioning using the outside air by the humidity control means or the sensible heat exchange means.
Therefore, the air-conditioning target space can be circulated while air-conditioning the air-conditioning target space and air-conditioning the air-conditioning target space, and the above-described first to sixth feature configurations can achieve the operational effects.

The configuration is such that the passage 4 is ventilated.
That is, the ventilation direction of the supply air passage 2 and the ventilation direction of the exhaust air passage 4 are opposite to each other.

The humidity control setting speed and the total heat exchange setting speed are set in advance and stored in the operation control unit 11.
Hereinafter, description will be added on how to set the humidity control setting speed and the total heat exchange setting speed.
The humidity setting speed will be described in detail in a ninth embodiment to be described later. However, when the rotation speed is 1.3 times / minute, the humidity control body 6 performs dehumidification of the humidity control section L. Since the performance is maximized, the set speed for humidity control is set to 1.3 times / minute, for example.

The solid line in FIG. 35 is the result of verifying the total heat exchange performance of the humidity control section L assuming the summer season when the air-conditioning target room is cooled, and the heater 8 for humidification heating is set in a heating stopped state. In addition, the rotational speed of the humidity control body 7 is changed in a state in which the air supply air path 2 is in a state where the air supply air path 2 and the exhaust air path 4 are ventilated in a state where the air supply air path 2 is hotter and humid. The total heat exchange performance of the humidity control section L at enthalpy is compared with 100% when the rotation speed is 1.3 times / minute.
Further, the broken line in FIG. 35 verifies the total heat exchange performance of the humidity control section L in the winter when the air-conditioning target room is heated, and the humidifier heating heater 8 is in a heating stopped state. In addition, the rotational speed of the humidity control body 7 is changed in the state where the exhaust air passage 4 is in a state of higher temperature and humidity and the air supply air passage 2 and the exhaust air passage 4 are ventilated. The total heat exchange performance of the humidity control section L at the rotation speed is compared with enthalpy, assuming that the rotation speed is 1.3 times / minute as 100%.

That is, when the air-conditioning target room is heated, such as in the winter, when the exhaust air EA is in a higher temperature and humidity state than the supply air SA, the total heat exchange performance of the humidity control section L is that of the humidity control body 7. When the rotational speed is higher than 1.3 times / minute, which is the setting speed for humidity control, the rotational speed becomes higher. When the rotational speed is in the range of 2.8 to 5.3 times / minute, the speed becomes 4.7 times / minute. It turns out to be the best.
Further, when the supply air SA is in a higher temperature and humidity state than the discharge air EA, such as in summer when the air-conditioned room is cooled, the total heat exchange performance of the humidity control section L is that of the humidity control body 7. When the rotational speed is higher than the humidity control setting speed of 1.3 times / minute, the rotational speed becomes higher, and becomes higher in the range of 4.0 to 5.3 times / minute, and when the speed is 4.7 times / minute. To be the best

Therefore, when the air-conditioning target room is heated, such as in the winter, when the exhaust air EA is hotter and humid than the supply air SA, the total heat exchange setting speed is set to 2 of the humidity adjustment setting speed. It is preferably set to 2 to 4.1 times, and most preferably set to 3.6 times the set speed for humidity control.
When the supply air SA is hotter and humid than the exhaust air EA, such as in summer when the air-conditioning target room is cooled, the total heat exchange setting speed is set to 3% of the humidity adjustment setting speed. It is preferable to set it to .1 to 4.1 times, and it is most preferable to set it to 3.6 times the set speed for humidity control.

  As mentioned above, it turns out that the total heat exchange performance of the humidity control part L can be improved by making the rotational speed of the humidity control body 6 higher than the setting speed for humidity control.
