Description

{Dehumidification air conditioner for swimming pool}

The present invention relates to a pool dehumidifying air conditioner, and more particularly, to a pool dehumidifying air conditioner in which air is recirculated and supplied to a swimming pool in order to always keep the inside of the pool at a proper humidity and temperature.

Since the inside of the swimming pool is exposed to high humidity environment due to its characteristics and it is necessary to maintain a constant temperature at all times, a system capable of precisely controlling the inside environment of the swimming pool is needed.

If these controls are not working properly, high humidity can cause bacteria, fungi, viruses and air quality to decrease and harm the human body. Also, high relative humidity can cause buildings to corrode and destroy structures, and condensation on the walls can reduce the quality of many building materials. Furthermore, in the worst case, the roof may collapse due to corrosion from condensation on the structure.

Currently, dehumidifiers and air conditioners are used in swimming pools to solve these problems, but most of them are dehumidifiers and air conditioners designed for swimming pools. .

There is also a device for heating the air and water inside the pool, but the energy consumption during the heating process is too high, resulting in excessive expenditure and environmental problems due to waste of energy.

It is an object of the present invention to provide a pool dehumidifying air conditioner capable of automatically maintaining a constant humidity and a temperature inside a swimming pool and minimizing energy consumption.

To achieve the above object, according to the present invention, there is provided a pool dehumidifying air conditioner for simultaneously controlling humidity and temperature of a swimming pool, comprising: a housing having an inlet port through which air is sucked into the pool and a supply port through which air is supplied to the pool; An evaporator for lowering the humidity by lowering the temperature of the air through heat exchange between the high-temperature and high-humidity air sucked into the inlet port and the refrigerant moving through the refrigerant pipe; A return fan for sucking air passing through the evaporator; A condenser for exchanging heat with air passing through the return fan to a high temperature state; A supply fan for supplying air passing through the condenser to the pool through the supply port; A compressor installed between the evaporator and the condenser to convert the refrigerant having passed through the evaporator into a high temperature and a high pressure state; An expansion valve installed between the condenser and the evaporator to convert the refrigerant passing through the condenser into a low temperature and a low pressure state, and a controller for controlling the compressor, the return fan, and the supply fan, A condenser, and a supply fan sequentially through the evaporator, the return fan, the condenser, and the supply fan, and is discharged to the swimming pool.

A discharge damper for discharging air to the outside and a suction damper for sucking outside air are provided between the return fan and the condenser so that the amount of air can be adjusted.

An inner wall temperature sensor and an inner wall humidity sensor are installed on the inner wall of the swimming pool. An inner wall supply pipe for moving the air passing through the supply fan is installed on the inner wall, and the controller receives data from the inner wall temperature sensor and the inner wall humidity sensor And compares the dew point temperature corresponding to the inner wall humidity data with the inner wall temperature data, and when the inner wall temperature data is equal to or lower than a predetermined temperature, air passing through the condenser is discharged through the inner wall supply pipe, thereby preventing condensation on the wall .

Preferably, the supply fan supplies an air amount smaller than the amount of air sucked in the return fan to the pool, and maintains the upper portion of the water in the pool at a negative pressure.

The pool dehumidifying air conditioner includes a first branch pipe branched from the refrigerant pipe between the compressor and the condenser; A second branch pipe branched from the refrigerant pipe between the condenser and the expansion valve; And an external condenser installed between the first branch pipe and the second branch pipe and performing heat exchange with the outside air.

The configuration and operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a basic configuration of a swimming pool dehumidifying air conditioner according to the present invention will be described.

The dehumidifying air conditioner of the present embodiment includes a housing 100, an evaporator 110, a return fan 210, a condenser 130, an air heater 132, a supply fan 220, a compressor 120, an expansion valve (Not shown), a discharge damper 250, a suction damper 230, and a mixing damper 240.

The housing 100 forms an outer appearance and may be installed outside or inside the swimming pool where various components are mounted. The air inside the swimming pool is sucked into the housing 100 and then supplied to the swimming pool.

The housing 100 is formed with an air inlet 102 through which air in the indoor pool is sucked and a supply port 104 through which air is supplied to the indoor pool.

The evaporator 110 is installed in the vicinity of the inlet port 102 of the housing 100 so that the air sucked into the housing 100 passes first through the evaporator 110.

The compressor 120, the condenser 130, the expansion valve 150 and the evaporator 110 are connected to each other by a refrigerant pipe 111. The refrigerant pipe 111 is filled with a freon gas having relatively easy vaporization and liquefaction, It contains the same refrigerant.

Since the low-temperature and low-pressure refrigerant passes through the evaporator 110, the air in the pool sucked into the suction port 102 is rapidly reduced in temperature as it passes through the evaporator 110, so that the water vapor in the air condenses, . The humidity of the air passing through the evaporator 110 is thus lowered, and the water vapor in the liquefied state is returned to the pool or discharged to the outside.

The air that has passed through the evaporator 110 and is in a low-temperature dry state passes through the return fan 210 and then enters the air mixing chamber.

The air mixing chamber includes a suction damper 230, a discharge damper 250, a mixing damper 240, and a partition 260.

The suction damper 230 and the discharge damper 250 are installed on the housing 100 and are provided on mutually facing surfaces. That is, since the suction damper 230 and the discharge damper 250 are installed on the surfaces of the housing 100 facing each other, the installation area of the damper can be effectively reduced. A partition wall 260 separating the discharge damper 250 and the suction damper 230 is installed in a diagonal direction so as to surround the return fan 210 and the discharge damper 250. By this type of partition wall 260, the air discharged to the outside and the air circulated to the inside can be efficiently managed.

That is, the ratio of the air discharged to the outside and the air circulated to the inside can be determined according to the opening ratio of the discharge damper 250 and the mixing damper 240, and the mixing damper 240 and the suction damper 230 The air passing through the evaporator 110 and the outside air can be mixed smoothly.

In order to maintain the fresh environment of the inside of the swimming pool, it is necessary to periodically vent the inside air to the outside. In this case, when the discharge damper 250 is opened, air having passed through the return fan 210 is discharged to the outside.

A temperature sensor and a humidity sensor are installed on the outside of the suction damper 230, the air inlet 102 and the air mixing chamber, and each device in the housing 100 is installed on the basis of data received from the temperature sensor and the humidity sensor. Respectively. That is, an external temperature sensor and an external humidity sensor for measuring the temperature and humidity of the outside air are installed outside the suction damper 230, and the temperature and humidity of the inside air of the pool are set between the evaporator 110 and the return fan 210. An indoor temperature sensor and an indoor humidity sensor for measuring humidity are installed in the partition wall 260. An intermediate temperature sensor and an intermediate humidity sensor for measuring the temperature and humidity of air passing through the evaporator 110 are also installed in the partition wall 260. [

The energy saving mode is operated by changing the operation mode of the pool dehumidifying air conditioner according to the external condition to minimize energy use.

Specifically, the control unit stores data values of graphs relating to temperature, humidity, and dew point temperature as shown in FIG. 3, and receives set values related to optimal temperature and humidity from a user. For example, the set value of the pool can be set to 28 ° C and 60% humidity. These settings are used to divide the graph into four zones based on the temperature and humidity axes.

For example, if the temperature and humidity data transmitted from the inlet 102 is located in zone A and the outside temperature and humidity transmitted from outside the suction damper 230 are located in the lower left zone of the graph, It means high temperature and high humidity, and the outside air is lower than the air inside the swimming pool and shows a dry state. In this case, the control unit fully opens the suction damper 230 to bring the outside air to 100%, closes the mixing damper 240, and opens the discharge damper 250. At this time, the operation of the compressor 120 can be stopped.

Similarly, when the temperature and humidity data transmitted from the intake port 102 are located in zones B, C, and D, respectively, and the outdoor temperature and humidity transmitted from outside the suction damper 230 are respectively as shown in the graph, 120 are not actuated and the suction damper 230 is opened to bring out the outside air.

The compressor (120) uses a plurality of compressors having different capacities from a small capacity to a large capacity, and each compressor is controlled by a solenoid valve. A small capacity compressor is used when bringing a lot of outside air, and a compressor having a large capacity is used as the air circulating inside the swimming pool is used.

In this way, the control unit continuously compares the external data transmitted from the external temperature sensor and the external humidity sensor with the internal data transmitted from the indoor temperature sensor and the indoor humidity sensor to determine the operation method.

That is, when the external data is closer to the set value, the operation of the compressor 120 is stopped or the compressor is switched to a smaller capacity compressor, and the suction damper 230 is opened to bring out the outside air. Further, when the internal data is closer to the set value, the suction damper 230 is closed and the compressor 120 is operated.

The air that has passed through the mixing damper 240 and the suction damper 230 is mixed and passes through the condenser 130. When the high-temperature and high-pressure refrigerant passes through the condenser 130, the refrigerant undergoes heat exchange with the air, and the temperature of the refrigerant is lowered while the temperature of the refrigerant is increased.

The swimming pool should always maintain the proper temperature and humidity. The temperature is suitably between 28 ℃ and 29 ℃, and the humidity is between 50% and 60%. In the present embodiment, when the air sucked into the intake port 102 passes through the evaporator 110, the temperature is approximately 15 ° C to 16 ° C. When the air passes through the condenser 130, the air is heated to approximately 28 ° C, It can be supplied to the inside. Further, in order to adjust an appropriate temperature, fine control is possible by adjusting the amount of air through the suction damper 230 and the discharge damper 250 in the air mixing chamber.

On the other hand, when it is necessary to supply more high-temperature air according to the environmental conditions of the swimming pool, the auxiliary heater 132 may be installed to further raise the temperature of the air. The air that has passed through the auxiliary heater 132 is supplied to the inside of the pool through the supply fan 220.

The operation of the energy saving mode according to the present embodiment will be described with reference to FIG. In Fig. 4, the dotted line indicates the set temperature inside the swimming pool, and the solid line indicates the outside temperature.

In FIG. 4, the zone (1) is a zone where the outdoor temperature is lower than the room temperature during the day when the swimming pool is opened and indoor cooling is required, so that the intake damper (230) is opened by the air mixing chamber to cool the room by sucking the outside air. This situation is usually from 6:00 am opening the pool to 12:30 pm when the outside temperature rises.

② The zone is a zone where the outside air temperature is higher than the room temperature and the room is cooled by minimizing the suction of the outside air and activating the compressor.

③ When the outside air temperature falls below the room temperature at about 7:30 in the early evening, the control unit starts the operation in the energy saving mode. This driving method continues until about 11 pm when the swimming pool is closed.

④ If the temperature of the pool is lower than the set value at the time of closing, the control unit closes the intake damper until the pool opens the next morning. On the other hand, if the pool water temperature exceeds the set temperature and the additional pool water evaporation cooling is required to set the set temperature, the control unit will continue to circulate cold and dry air on the surface of the water until the pool water is set to the set temperature.

In the pool dehumidifying air conditioner according to the present embodiment, two fans are installed as a return fan 210 and a supply fan 220. The return fan 210 mainly functions to suck air in the inside of the swimming pool, and the supply fan 220 serves to supply the air that has passed through the inside of the housing 100 to the swimming pool. In the present embodiment, the return fan 210 and the supply fan 220 maintain the upper portion of the pool water at a negative pressure, thereby suppressing an increase in humidity inside the swimming pool and creating a pleasant environment.

Specifically, when people swim in a pool, evaporation is more likely to occur due to the effects of water swell and convection. Promotion of the evaporation of the pool water plays a role of increasing the humidity inside the swimming pool, so that it is necessary to perform dehumidification more, so the energy consumption is increased.

In order to solve such a problem, in this embodiment, two fans are provided, and the capacity of the return fan 210 for sucking air is made 5% to 10% larger than the capacity of the supply fan 220. The amount of the air sucked by the return fan 210 becomes greater than the amount of the air supplied into the pool from the supply fan 220 so that the atmospheric pressure of the upper part of the pool water 410 is lower than the atmospheric pressure of the pool peripheral part 420 And a negative pressure is formed. In this state, since pressure is formed from the swimming pool peripheral part 420 toward the swimming pool water 410, evaporation of water becomes difficult. Therefore, it is possible to suppress the increase of the humidity inside the swimming pool, thereby reducing the running time of the pool dehumidifying air conditioner and reducing the energy consumption.

On the other hand, an inner wall temperature sensor 314 and an inner wall humidity sensor 316 are provided on the inner wall of the indoor pool according to the present embodiment. The inner wall temperature sensor and the inner wall humidity sensor 316 are preferably installed at the lowest temperature of the inner wall of the indoor pool.

An inner wall supply pipe 310 connected to the supply fan 220 and supplying air to the inside of the pool is installed at the upper part of the inner wall. .

Pool walls are relatively cold due to the cold temperature of the outside air. Condensation of water vapor on these walls will not only become a habitat for the mold, but will also cause corrosion of the walls.

In this embodiment, data on the inner wall temperature and the inner wall humidity are transmitted to the control unit by the inner wall temperature sensor 314 and the inner wall humidity sensor 316 provided on the inner wall of the swimming pool. The control section stores dew point temperature data according to the relative humidity. The control unit receives data on the inner wall temperature and the inner wall humidity, and compares the data with the dew point temperature data.

That is, the dew point temperature data corresponding thereto is extracted based on the inner wall humidity data, and the extracted dew point temperature data is compared with the inner wall temperature data. As a result of the comparison, when the inner wall temperature data is higher than the extracted dew point temperature data, the inner wall condensation prevention mode is stopped. When the inner wall temperature data is equal to or lower than the extracted dew point temperature data, the inner wall condensation prevention mode is activated, And supplies the air to the inner wall supply pipe 310.

By using the inner wall condensation prevention mode according to the present embodiment, it is possible to prevent condensation on the wall surface inside the swimming pool while minimizing energy consumption.

On the other hand, in the refrigerant pipe between the compressor 120 and the condenser 130, the branched first branch pipe 113 is formed, and in the refrigerant pipe between the bed pipe 130 and the expansion valve 150, The engine 115 is formed. An external condenser 170 is installed between the first branch pipe 113 and the second branch pipe 115. Accordingly, the external condenser 170 is installed outside the housing 100 to perform heat exchange with the outside air of the swimming pool.

On the other hand, the first branch pipe (113) is provided with a solenoid valve (122) to control the flow of the refrigerant. That is, the flow of the refrigerant can be controlled by using the first solenoid valve 124 provided between the compressor 120 and the condenser 130 and the second solenoid valve 122 installed in the first branch pipe 113.

That is, the control unit is configured to input the optimum temperature and humidity as the set value. The controller receives the set value and normally maintains a predetermined temperature and humidity since air is supplied through the condenser 130 inside the housing 100. [ This operation is for always keeping the internal environment of the swimming pool constant and is always maintained so that the temperature change is not large.

However, when it is necessary to cool the inside of the pool relatively rapidly, the first solenoid valve 124 is closed and the second solenoid valve 122 is opened. Then, the refrigerant passes through the external condenser 170, not through the internal circuit of the housing 100. In this state, since the air whose temperature has dropped through the evaporator 110 does not exchange heat with the condenser 130, the pool can be rapidly cooled by supplying the low-temperature air to the pool.
