Description

Indoor air conditioning system {INDOOR AIR CONDITIONING APPARATUS}

The present invention relates to an indoor air conditioning apparatus, and more particularly, to an indoor air conditioning apparatus capable of controlling temperature, humidity, and cleanliness of a room.

Recently, high-rise, meat densification, high insulation, and large-sized units are keywords of change taking place in apartments. As the conversion from the rectangular plane of the existing plate-shaped bearing wall structure to a ramen structure including pillars and slabs, the residential space, such as a polygonal plane with multiple flavors, is changing more dynamically. In addition, a curtain wall method such as an office building is adopted in a residential building in consideration of the elevation of the entire building, excluding the protruding porch. Due to these changes, many changes have been made to residential cooling and ventilation systems.

First, as the cooling load increased due to the increase in the exclusive area and the structure of the curtain wall, the cooling equipment became a necessary condition. Also, in the case of high-rise buildings, there are structures where occupants cannot open windows arbitrarily, and due to the high-density structure, natural ventilation due to the interstitial winds is almost unpredictable, and mechanical ventilation with heat exchangers is mostly applied. have. In addition, it is essential for residential buildings such as apartment houses to consider building drafts, which have been reviewed only in commercial buildings in the past, such as the effect of exhaust from the outdoor unit of the air conditioner on the adjacent upper floor as well as the performance review of the ventilation system by external static pressure. It becomes the matter.

Currently, indoor air conditioning systems of various structures that can control the temperature, humidity, and cleanliness of indoor air have been developed and used, but research and development for product development that can further improve air conditioning performance and reduce operating costs is ongoing. Is being made.

The indoor air flowing into the air inlet chamber 114 passes through the filter unit 175 and flows into the heat exchange chamber 116, and after being cooled or heated by the heat exchange unit 188 in the heat exchange chamber 116, the indoor air inlet It is re-supplied indoors through 143.

In addition, the air conditioning apparatus 100 according to the present invention may operate in a damping operation mode. When the indoor air conditioning apparatus 100 operates in the vibration suppression operation mode, it operates in the same manner as the above-described air conditioning operation mode, but the operation of the heat exchange unit 188 is stopped. That is, except for supplying a heat medium of high or low temperature to the heat exchange unit 188, the same operation as in the air conditioning operation mode removes dust contained in the indoor air through the filter unit 175, and then re-supplies it to the room. It might be.

6 shows the case where the indoor air conditioning apparatus 100 operates in a ventilation operation mode.

In the ventilation operation mode, the outside air inlet damper 139 opens the outside air inlet passage 137 of the outside air inlet 135, and the indoor exhaust damper 155 opens the indoor exhaust passage 153 of the indoor exhaust 151. The indoor air discharge damper 169 opens the indoor air discharge flow path 167 of the indoor air discharge unit 165. In addition, the bypass damper 161 shields the bypass passage 159. In this state, by operating the main blower 173 and the exhaust blower 186, indoor indoor air flows into the total heat exchanger installation room 112 through the indoor exhaust portion 151, and outside air flows into the outside air inlet 135. Through it is introduced into the total heat exchanger installation room (112). The outside air flowing into the total heat exchanger installation chamber 112 is exchanged with the indoor air exhausted while passing through the total heat exchanger 180, and then passes through the air inlet chamber 114 and the heat exchange chamber 116 in turn to thereby enter the indoor inlet portion 143. Is supplied indoors. Then, the indoor air flowing into the total heat exchanger installation room 112 is exchanged with the outside air while passing through the total heat exchanger 180, and then discharged to the outside of the building through the indoor air discharge unit 165.

7 shows a case where the indoor air conditioning apparatus 100 operates in a complex operation mode. The combined operation mode is an operation mode in which ventilation and cooling operations or ventilation and heating operations are simultaneously performed.

In the combined operation mode, the outside air inlet damper 139 opens the outside air inlet passage 137 of the outside air inlet 135, and the indoor exhaust damper 155 opens the indoor exhaust passage 153 of the indoor exhaust 151. The indoor air discharge damper 169 opens the indoor air discharge flow path 167 of the indoor air discharge unit 165. In addition, the bypass damper 161 opens the bypass passage 159. In this state, by operating the main blower 173 and the exhaust blower 186, indoor indoor air flows into the total heat exchanger installation room 112 through the indoor exhaust portion 151, and outside air flows into the outside air inlet 135. Through it is introduced into the total heat exchanger installation room (112).

The outside air flowing into the total heat exchanger installation chamber 112 exchanges heat with indoor air exhausted while passing through the total heat exchanger 180 and then flows into the air inlet chamber 114. Then, the indoor air flowing into the total heat exchanger installation room 112 is exchanged with the outside air while passing through the total heat exchanger 180, and then discharged to the outside of the building through the indoor air discharge unit 165. At the same time, a portion of the indoor air flowing into the indoor exhaust unit 151 is bypassed to the air inlet chamber 114 through the bypass passage 159. The outside air and the indoor air flowing into the air inlet chamber 114 flow through the filter unit 175 to the heat exchange chamber 116, and after being cooled or heated by the heat exchange unit 188 in the heat exchange chamber 116, the room It is supplied to the room through the inlet 143.

When a high-temperature heat medium is supplied to the heat exchange unit 188 in the complex operation mode, the indoor air conditioning apparatus 100 may supply and heat the air to the room to ventilate and heat the room. In addition, when a low-temperature heat medium is supplied to the heat exchange unit 188 in the combined operation mode, the indoor air conditioning device 100 may supply cooling air to the room to ventilate and cool the room.

As described above, the indoor air conditioning apparatus 100 according to an embodiment of the present invention may operate in various driving modes such as a ventilation operation mode, a cooling operation mode, a heating operation mode, and a complex operation mode.

In addition, the indoor air conditioning apparatus 100 according to an embodiment of the present invention has a simple structure, low-cost operation, and easy maintenance.

The present invention has been described as a preferred example, but the scope of the present invention is not limited to the form described and illustrated above.

For example, the indoor air conditioner 100 may be supplied with a heat medium to the heat exchange unit 188 even in a ventilation operation mode to perform cooling or heating functions in addition to ventilation.

In addition, although the drawings show that the air inlet chamber 114 is disposed above the total heat exchanger installation chamber 112 and the heat exchange chamber 116 is disposed above the air inlet chamber 114, the total heat exchanger installation chamber is shown. The positions of the 112 and the air inlet chamber 114 and the heat exchange chamber 116 may be variously changed.

Above, the present invention has been shown and described in connection with a preferred embodiment for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as described and described as such. Rather, it will be understood by those skilled in the art to which the present invention pertains that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims.
