The operation of the swimming pool cooling / heating apparatus according to the present invention constructed as described above will be described below.

The cooling and heating unit 20 is operated to heat the water in each pool, that is, the spa pool 11, the infant pool 12 and the management pool 13 by using the cooling and heating apparatus of the pool, 22) (which may be made of a heat exchange fluid). In the case of using a heat pump as described above, it is preferable that nighttime electricity can be used, and it is preferable that the load is constantly applied when the load on the pool is light. However, the present invention is not limited to this, and when the heat pump uses geothermal heat or air heat, operating conditions may vary.

In order to heat the water in the spa pool 11 in the state where the heat is accumulated in the heating storage tank 22 as described above, the third circulation pump (not shown) installed in the first branch supply pipe 153 connected to the second supply pipe 152 The water in the heating storage tank 22 is returned to the second return pipe 162 through the first heat exchanger 181 and the water in the spa pool 11 is returned to the first circulation pipe 191, To the first heat exchanger (181).

As described above, the indoor humidity of the swimming pool is relatively increased in the process of heating each swimming pool and the male and female dressing rooms 14 and 15. The humidity in the swimming pool is controlled by the dehumidifying / Lt; / RTI >

More specifically, in order to reduce the humidity inside the swimming pool, an evaporator 141 having a humidifier, which is controlled by the smart damper 118 and is introduced through the intake port 113 by the first blower 130, Through the condenser 142 and the heating coil 143, to the air supply device 114 for returning to the room. In this process, a part of the air can be exhausted by operating the damper on the side of the exhaust port 116. By operating the damper 115a provided on the outside air intake port 115, a part of the outside air is introduced through the intake port 113 And the ventilation can be performed.

In order to dehumidify the humidifier in the room without ventilation, as shown in FIG. 2, a smart damper 118 is used to communicate the main passage 111 so that the humidifier introduced by the first blower 130 is communicated with the main passage 111 Through the evaporator 141 installed in the evaporator 141, the condenser 142 and the neutral coil 143 and then returned to the room through the air supply device 141 by the second blower 131. In this process, the humidifier passing through the main passage 111 is cooled to a temperature below the dew point temperature and condensed while passing through the evaporator 141 having a relatively low temperature. The dehumidified dry air passing through the evaporator 141 is heated while passing through the condenser 142 and the heating coil 143. Generally, the temperature and humidity conditions of the swimming pool are maintained at 30 ° C. and the humidity is 50%. Therefore, it is necessary to heat the dry air after dehumidification. The condensate is firstly heated by the condenser 142, The heating temperature of the dry air can be controlled.

In order to dehumidify and ventilate the room air, some or all of the smart damper 118, the damper installed at the outside air intake opening 115 and the exhaust opening 116 are opened. It is preferable that the rate of shut-down of the damper is proportionally controlled in consideration of the intake amount of the outside air and the exhaust amount of the exhaust port 116.

A part of the humidifier introduced through the intake port 113 due to the opening of the smart damper 118 and the first and second damper 115a and 116a passes through the plastic plate heat exchanger 119, (Not shown). The outside air flowing through the outside air intake port 115 passes through the plastic plate heat exchanger 119 and is heat-exchanged with a humidifier which is discharged after passing through the plastic heat exchanger 119, ≪ / RTI > A part of the humidifier introduced through the intake port 113 flows into the main duct 111 through the smart damper 118 and is mixed with the ambient air. The humidifier mixed with the outside air is dehumidified while passing through the evaporator 141 as described above and then heated by passing through the condenser 142 and the heating coil 143 and then blown by the second blower 131, (114).

As described above, in the course of the dehumidification of the indoor air, the outside air flowing through the outside air intake port 115 and the humidifier discharged through the air outlet 116 are heat-exchanged by the plastic plate heat exchanger 119, The energy required for the heating of the heater can be saved. Here, since the heat exchanger for heat exchange between the outside air and the exhausted humidifier is made of the plastic plate heat exchanger 119, the problem of the conventional heat exchanger made of aluminum is that heat exchange due to corrosion due to salt or moisture, design constraints, It is possible to solve difficulties due to transportation, installation and maintenance of the machine. Particularly, the plastic plate heat exchanger 119 is easy to carry and install because of its light weight, can be freely designed according to the size adjustment, and is easily cleaned.

In the meantime, the swimming pool cooling / heating system of the present invention further includes an auxiliary cooling unit for cooling the water stored in at least one of the pools to lower the humidity of the pool. In case of lowering the temperature for indoor air conditioning in the swimming pool, it is more effective in terms of cost and environment to lower the temperature of the storage pool than to lower the air temperature by using the air conditioner. Since the swimming pool cooling and heating system of the present invention includes the auxiliary cooling unit 130, the temperature of the water can be lowered in a relatively short period of time, so that indoor air and humidity can be lowered. That is, the cooling unit 125 cools the water in the balancing tank 123 and supplies the cooled water to the pool (infant pool or management pool) to lower the temperature by the auxiliary supply pipe 121 and the auxiliary return pipe 122 ). ≪ / RTI > Through this process, the temperature of the water stored in the pool can be easily controlled by supplying the cooled water to the heated pool water, and thereby the humidity and the temperature of the swimming pool can be controlled. It is desirable to use a pool that is not directly used to control the humidity and air temperature through the temperature control of the water stored in such a pool.

As described above, the cooling and heating device of the swimming pool according to the present invention can heat the indoor air using waste heat recovered when the humidity is controlled, and controls the temperature of the water stored in the pool to control the humidity and temperature of the indoor air It is possible to maximize energy efficiency due to cooling and heating of the swimming pool.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

The cooling and heating device of the swimming pool of the present invention is applicable not only to a swimming pool but also to various industrial facilities and facility cultivation complexes.
