Description

The present invention relates to a water intake device that extracts moisture from the atmosphere, and controls the air volume or speed of air taken in according to the outside air temperature, and efficiently cools the air in accordance with the cooling capacity of the heat exchanger. The water can be taken out.
Furthermore, in order to make the cooling capacity of the heat exchanger more efficient, a water intake method that realizes recycling without generating waste water by using the waste water from the reverse osmosis membrane water purifier for cooling the compressor is provided.

  Conventionally, various apparatuses that take in moisture from the atmosphere and use it for domestic water such as drinking water have been proposed. Each of them is the name of a fresh water generator, a water intake device or a water supply device, and is condensed and taken out due to the temperature difference between the temperature of the atmosphere and the cooling temperature by the heat exchanger.

  However, not only the air volume (wind speed) control and the cooler control are individually controlled, but the air intake controller and the cooling controller work together, and the cooling capacity of the heat exchanger must be fully utilized. Can't get water well.

In order to solve the above problems, an air intake controller that controls the air volume or speed of the air taken into the water intake mechanism by the intake fan according to the outside air temperature, and a cooling controller that works in conjunction with the air intake controller are provided. The cooling temperature by the heat exchanger was controlled by the central processing unit (CPU), and water intake was realized by the efficient cooling capacity of the heat exchanger.
The “cooling capacity of the heat exchanger” is not constant depending on the outside air temperature, the air volume (air speed) taken into the intake mechanism, and the cooling temperature by the heat exchanger determined by the refrigerant of the compressor.
In the present invention, a cooling controller that is linked to the atmospheric intake controller is provided, and the surface temperature of the stainless fins of the heat exchanger is controlled by the central processing unit, and the moisture in the atmosphere is reduced by the efficient cooling capacity of the heat exchanger. I tried to take it out.
Table 2 shows empirical values indicating the range of cooling temperature by a heat exchanger with good water intake efficiency based on the outside air temperature and the air volume (wind speed) of the air taken in.

  Furthermore, the moisture in the atmosphere taken out from the water intake mechanism is temporarily stored in a water storage tank, sent to a reverse osmosis membrane water purifier by a pressure pump, and purified through this water purifier to obtain drinking water. By using the drainage discharged from the reverse osmosis membrane water purifier for cooling the compressor, the cooling capacity of the heat exchanger is further improved, and efficient water extraction is realized.

  In the present invention, the intake fan and the compressor are controlled by the respective control bases, and the air flow rate (wind speed) regulation introduced into the water intake mechanism by the air intake controller in relation to the outside air temperature and the cooling controller is more efficient. The cooling capacity of the heat exchanger can be controlled.

  In addition, the water extracted by the water intake mechanism is purified with a reverse osmosis membrane water purifier to make drinking water, and the waste water from the reverse osmosis membrane water purifier is discarded without being discarded. By passing the pipe, the temperature rise of the compressor was suppressed, the refrigerant temperature was adjusted, the cooling capacity of the heat exchanger was increased, and the performance maintenance became extremely effective.

  Therefore, the cooling rate of the heat exchanger by the refrigerant of the compressor is about 15 to 25% faster than before, and water droplets obtained from the atmosphere can also be efficiently taken in by 15 to 25%. (See Table 3)

Explanatory drawing which shows the water intake mechanism of this invention. Explanatory drawing which shows the water intake method of this invention.

  In FIG. 1, reference numeral 1 denotes a water intake mechanism, which has an outside air temperature sensor 2, a filter 3 for removing dust in the air, a sterilizer 4, a heat exchanger 5 equipped with a compressor, and one or a plurality of intake air. And a fan 6.

The sterilizer 4 uses a plasma ion generator or the like to sterilize viruses, bacteria, etc. in the range of about 6 to 8 tatami around and around the equipment.
When the compressor is started, the heat exchanger 5 compresses the refrigerant and sends it out to the refrigerant pipe. The refrigerant pipe cools the surface of the stainless fin, and the cooling temperature by the heat exchanger is determined.

  Reference numeral 7 denotes an air intake controller which senses the outside air temperature by the temperature sensor 2 and controls the air volume (wind speed) of the air taken in by the intake fan.

  When the outside air temperature is 35 ° C. and the humidity is 45% and the cooling temperature by the heat exchanger 5 provided with the compressor is constant, the air volume (wind speed) of the air by the intake fan 6 is reduced to increase the efficiency.

  This is because applying hot air of 35 ° C to the heat exchanger increases the temperature and lowers the efficiency of water intake, so the air volume (wind speed) by the intake fan is reduced and cooling by the heat exchanger is performed. Efficient water intake without increasing the temperature.

  Further, when the outside air temperature is 15 ° C. and the humidity is 45%, more intake water can be obtained by increasing the air volume (wind speed) of the atmosphere by the intake fan and taking in a large amount of outside air. Data DT of the temperature sensor 2 that senses the outside air temperature is sent to the air intake controller 7, and control data DT 1 is sent to the intake fan 6.

  Reference numeral 8 denotes a cooling controller, which is effective when interlocked with the air intake controller 7. In response to changes in the outside air temperature, if the outside air temperature becomes high, the cooling temperature by the heat exchanger is lowered, and if the outside air temperature becomes low, water can be taken in more efficiently by appropriately raising the cooling temperature.

  Reference numeral 9 denotes a central processing unit (CPU) that individually controls the air intake controller 7 and the cooling controller 8 according to changes in the outside air temperature, as well as the cooling temperature and refrigerant flow determined by the heat exchanger determined by the refrigerant feed amount of the compressor. The cooling controller is controlled according to changes in the situation, etc., so that it has an efficient heat exchanger cooling capacity.

As shown in Table 2, when the outside air temperature is 10 ° C., 20 ° C., 30 ° C., 40 ° C., the air volume (wind speed) of the air taken in changes as strong, medium, weak strong, weak, as a cooler It has been known as an empirical value that an effective heat exchanger cooling capacity can be obtained by setting the surface temperature of the heat exchanger to 0 ° C., −1.5 ° C., −4 ° C., and −5 ° C.
Further, when the outside air temperature was 0 ° C. or lower, the defrost lamp was turned on, the compressor was turned off after 30 minutes, and the intake fan was operated for 10 minutes with strong operation.

FIG. 2 is a route showing a water intake method.
In the present invention, the atmosphere is cooled by the temperature difference between the outside air temperature and the cooling temperature by the heat exchanger, and water droplets are generated. This water is temporarily stored in the water storage tank 10 (14 liters), and after a certain amount of water is stored, it is sent to the reverse osmosis membrane water purifier 15 by the pressure pump 13, and after filtered water purification, is sent to the hot water tank 16 or the cold water tank 18. . Appropriate drinking water can be taken out as hot water at 85 to 95 ° C. from the supply port 17, and cold water at 5 to 15 ° C. can be taken out from the supply port 19.

Reference numeral 5 denotes a heat exchanger. When the compressor 22 is started, the refrigerant is compressed and sent to the heat exchanger 5 through a refrigerant pipe, the surface of the stainless fin is cooled, and the air taken in from the atmosphere by the intake fan 6 is cooled. And make water drops.
A water storage tank 10 can store about 14 liters of water droplets. With float switch.

12 is a water container such as a portable bucket, and the manual switching valve 11 is operated so that water can be taken out in the event of a disaster.
13 is a pressurizing pump, which sends the water in the water storage tank to the reverse osmosis membrane water purifier 15 for filtration.

  14 is a pre-filter, which treats coarse waste with a 10 micron sediment filter and a 5 micron carbon filter.

Reference numeral 15 denotes a reverse osmosis membrane water purifier, and the membrane is a composite membrane having fine pores of 0.0001 micron, and removes harmful substances such as bacteria, viruses and heavy metals as much as possible. Finally, post carbon is provided to form a four-layer filter together with the filter.
A hot water tank 16 is provided with a 460 W heat band 16 a at the periphery of the tank to enable heating, and 85 to 95 ° C. hot water is obtained.

Reference numeral 18 denotes a cold water tank. A cooling pipe 18a is provided at the periphery of the cold water tank so that a coolant is sent to obtain cold water.
The hot water in the hot water tank 16 is transferred to the cold water tank 18 by the pump 20 via the solenoid valve (H) and can be sterilized with hot water. In addition, after sterilizing with a timer for about 3 minutes, it flows into the water storage tank 10 and is recycled.

  For recycling, a hot water sterilization method can be adopted once a day. At midnight (for example, 1:00 am), the solenoid valve (S) under the cold water tank 18 is opened to release all stored water (time setting. Next, the hot water tank 16 in the full water state (HL) is discharged. The heater 16a is turned on, the hot water in the tank is boiled again, for example, when the temperature reaches 80 to 90 ° C., the solenoid valve (H) is turned on, and water is supplied from the hot water tank 16 to the cold water tank 18 by the pump 20. After detecting that the hot water has reached level LL, the solenoid valve and the pump are turned off.

  After the set time (for example, 30 minutes), the compressor is started, the refrigerant is sent to the cooling pipe 18a, the stainless fins of the heat exchanger are cooled, and cold water is produced from the atmosphere. Once the water has been sterilized, the growth of bacteria becomes extremely low when the water temperature is 9 ° C. or lower. Since the water flowing into the cold water tank 18 is filtered by the reverse osmosis membrane water purifier, the bacteria are removed and the recycling can be performed without any trouble.

  The wastewater generated from the reverse osmosis membrane water purifier passes through the copper pipe wound around the compressor 22 to cool the compressor, the heat exchanger maintains a stable cooling temperature, and water drops from the atmosphere with stable efficiency. Is to produce. In addition, the position of the compressor is at the same level as the water storage tank 10, and the drainage of the reverse osmosis membrane water purifier circulates in the copper pipe 24 of the compressor 22, so that the cooling of the compressor is continued.

  Hereinafter, the sterilization method will be described.

A lot of general bacteria are generated in the 5-15 ° C cold water tank, but this product uses the hot water sterilization performed by transferring hot water from the hot water tank to the cold water tank and the water purification action by the reverse osmosis membrane water purifier. As a result, the generation of bacteria within 1 cc / 100 or less was almost completely achieved, which was almost zero.
As the sterilization means, chlorine sterilization and hot water sterilization are the most effective, and have several sterilization ability compared with silver, UV and the like.

In the present invention, water in the atmosphere taken out by the water intake mechanism is temporarily stored in a water storage tank, sent to a reverse osmosis membrane water purifier with a pressure pump, filtered and purified, and the filtered purified water is warm water tank or cold water. Means for sending water to the tank, means for taking out from the supply port as hot water or cold water as necessary, and recycling means for returning the purified water transferred to the cold water tank to a water storage tank after a certain time or as needed via an electromagnetic valve; It consists of a means for cooling the compressor through a copper tube wrapped around the outer periphery of the compressor of the heat exchanger without discarding the waste water from the reverse osmosis membrane water purifier, and efficiently controlling the cooling capacity of the heat exchanger It is characterized by.

According to the water intake method of the present invention, 100% recycling was realized. When used as normal drinking water, it is (20 liters / day) so that no waste water is generated.
Usually, from the atmosphere, heat exchangers produce 12 to 14 liters at a water temperature of 25 ° C and 70% humidity, and 8 to 10 liters at a water temperature of 10 ° C and humidity of 40%. It is possible to attach a system to make ponds, general rivers, bath remaining hot water, etc. into drinking water.

In this case, when the water temperature is 25 ° C., 288 liters are produced at 200 ml / min × 60 × 24 hours. When converted to a 2-liter plastic bottle. Comparable to 144.
Reference numeral 25 in the drawing indicates a filter that receives water droplets that are cooled from the heat exchanger and stores them in a water storage tank.

  This product does not require any water supply work, and if it has a power supply, it can produce water from the atmosphere. If a water supply port for disasters is provided, tap water can be added. In this case, there was no need for waterworks to be directly connected to tap water. Therefore, it can be installed anywhere regardless of location.

  Since the raw water of this product is extracted from the atmosphere using a temperature difference with a heat exchanger, it is water with extremely low hardness such as calcium and magnesium like distilled water and soft water. . Soft water significantly reduces the load on reverse osmosis membrane removal performance and enables recycling.

As shown in Table 1, the raw water of the present invention is always about 10 PPM as atmospheric moisture. When raw water is filtered using a reverse osmosis membrane water purifier with a 97% removal rate, the wastewater is a value obtained by multiplying the raw water by 1.8.
Even if the drinking water sent to the cold water tank or the hot water tank is repeatedly recycled, the water becomes the same value as the water purified by the reverse osmosis membrane water purifier of the raw water, and the number of recycling can be increased.

  In addition, when the load coefficient of the reverse osmosis membrane is 300 PPM or more, the load is significantly increased. Therefore, it is normal to limit the number of recycling to about six times. However, in the present invention, the raw water is the moisture in the atmosphere. When filtering with a reverse osmosis membrane water purifier excluding various bacteria, it was possible to extend the number of recycles, not limited to six.

  The city's tap water is about 100PPM, and the drainage is 180PPM multiplied by 1.8 at the first time, so it becomes 324PPM at the second recycling. Therefore, recycling is impossible.

In the present invention, since the raw water is water having a lower value than the total dissolved solids of distilled water and inorganic ions (TDS), it can be recycled repeatedly. In addition, since water is taken from the air in the middle of recycling, the waste water is diluted and the theoretical value means that the recycling can be performed any number of times without problems.

In order to take water most efficiently in response to changes in the outside air temperature, a cooling controller is provided and the cooling temperature by the heat exchanger is controlled by the central processing unit. The surface temperature of the heat exchanger as a cooler is set to 0 ° C. to −5 ° C. in response to changes in the air volume (wind speed) of the air taken into the intake mechanism as strong, medium, weak strong, and weak. Found that the cooling capacity of an efficient heat exchanger was the best. (See Table 2)

Table 3 is a table showing that water intake is increased when the compressor is cooled by passing the waste water from the reverse osmosis membrane water purifier in the present invention through a copper pipe wound around the outer periphery of the compressor.

Heat exchanger: Made by KAI GIKEN (Stainless steel fin specification)
Refrigerant: Alternative Freon R134a
Compressor: Hailey BSA645CR-RIENC
Copper tube: 7 rolls (6Φ)

Table 3 shows the case where the compressor is cooled by using the drainage from the reverse osmosis membrane water purifier with respect to the outside air temperature detected by the temperature sensor in any of the environmental conditions 1, 2 and 3 (the present invention). It is a comparison table of the water intake effect when not using it. In either case, the increase in water intake is obvious. This is data obtained by keeping the wind speed (4m / sec) by the cooling fan constant.

The amount of water obtained at an outside temperature of 9.3 ° C. was found to increase by 17%, and an increase of 20 to 25% was observed at around 25 ° C. outside temperature.

  In the present invention, the air intake controller controls the air volume (wind speed) of the air taken into the water intake mechanism, and also provides a cooling controller that works in conjunction with this to provide an efficient heat exchanger cooling capacity using a central processing unit. As it is maintained, the water intake efficiency is extremely high. In addition, recycling is realized through reverse osmosis membrane water purifiers without requiring waterworks, so operation is easy as long as a power source can be secured regardless of location.
