Description

열효율 및 안정성을 향상시킨 수영장용 제습공조기{Dehumidification air conditioner for swimming pool improving heat efficiency and stability}Dehumidification air conditioner for swimming pool improving heat efficiency and stability

본 발명은 열효율 및 안정성을 향상시킨 수영장용 제습공조기에 관한 것이며, 구체적으로 수영장 내부를 항상 적절한 습도 및 온도로 유지하며, 열효율 및 내구성을 향상시킨 수영장용 제습공조기에 관한 것이다.The present invention relates to a dehumidifying air conditioner for a swimming pool with improved thermal efficiency and stability, and more particularly, to a dehumidifying air conditioner for a swimming pool with improved thermal efficiency and durability while always maintaining the inside of a swimming pool at an appropriate humidity and temperature.

수영장 내부는 그 특성상 습도가 높은 환경에 노출이 되어 있고 항상 일정 온도를 유지해야될 필요성이 있으므로 수영장 내부환경을 정밀하게 컨트롤할 수 있는 시스템이 필요하다. The inside of the swimming pool is exposed to a high humidity environment due to its nature, and there is a need to maintain a constant temperature at all times, so a system that can precisely control the environment inside the swimming pool is required.

이러한 컨트롤이 제대로 되지 않을 경우, 높은 습도로 인하여 박테리아, 곰팡이, 바이러스의 증가와 공기의 질을 감소시키는 결과를 가져올 수 있고 인체에 해를 줄 수 있다. 또한, 높은 상대습도는 건물을 부식시키고 구조물이 파괴되는 원인이 될 수 있으며, 벽에 생기는 결로는 많은 건물자재의 질을 떨어뜨린다. 나아가 최악의 경우 구조물에 생기는 결로로 인한 부식으로 지붕이 무너져 내릴 수도 있다.If this control is not done properly, high humidity can result in an increase in bacteria, mold, and viruses and a decrease in air quality, which can be harmful to the human body. In addition, high relative humidity can corrode buildings and cause structural destruction, and condensation on walls degrades the quality of many building materials. Furthermore, in the worst case, the roof may collapse due to corrosion caused by condensation on the structure.

현재 이러한 문제를 해결하기 위하여 수영장에서 제습기 및 공기조화기를 사용하고 있으나, 대부분 수영장 전용으로 설계된 제습기 및 공기조화기가 아니라 수영장의 환경에 맞게 정밀한 컨트롤이 불가능하고 대충 사용자의 느낌에 따라 설비가 운용되고 있다.Currently, dehumidifiers and air conditioners are used in swimming pools to solve these problems, but most of them are not designed for swimming pools, so precise control is not possible according to the environment of the swimming pool, and the facilities are operated roughly according to the user's feelings. .

또한, 수영장용 제습공조기에서 압축기와 외부공기순환부와의 거리의 제한을 대폭 해소하여 공간적인 자유도를 향상시키는데 또 다른 목적이 있다.In addition, there is another object of improving the spatial freedom by greatly removing the limitation of the distance between the compressor and the external air circulation unit in the dehumidifying air conditioner for a swimming pool.

그리고, 상이 변하는 냉매를 이용한 사이클의 단점을 보완하여 히트펌프의 안정적인 제어가 가능한 수영장용 제습공조기를 제공하는데 또다른 목적이 있다.Another object of the present invention is to provide a dehumidifying air conditioner for a swimming pool capable of stably controlling a heat pump by supplementing the disadvantages of a cycle using a phase-changing refrigerant.

본 발명의 실시예의 구성 및 작용에 대하여 첨부한 도면을 참조하여 상세하게 설명한다.The configuration and operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1을 참조하면, 본 발명에 의한 수영장용 제습공조기는 하우징(100), 흡기팬(210), 배기팬(230), 증발기(110), 압축기(120), 저장부(400), 팽창밸브(150), 매질변경열교환부(710), 제2매질히터부(730), 공급팬(220)을 포함하여 구성된다.1, the dehumidifying air conditioner for a swimming pool according to the present invention includes a housing 100, an intake fan 210, an exhaust fan 230, an evaporator 110, a compressor 120, a storage unit 400, an expansion valve ( 150), a medium change heat exchange unit 710, a second medium heater unit 730, and is configured to include a supply fan (220).

상기 하우징(100)은 외관을 형성하며, 각종 부품이 실장되는 곳으로서 수영장의 외부 또는 내부에 설치될 수 있다. 수영장 내부 공기는 상기 하우징(100)으로 흡입되어 다시 수영장으로 공급되는 순환 구조로 되어 있다.The housing 100 forms an exterior, and may be installed outside or inside the swimming pool as a place where various parts are mounted. The air inside the swimming pool has a circulation structure that is sucked into the housing 100 and supplied back to the swimming pool.

상기 하우징(100)에는 실내수영장의 공기가 흡입되는 흡기구 및 상기 실내수영장으로 공기를 공급하는 배기구, 공급구가 형성되며, 상기 흡기구, 배기구 및 공급구에는 각각 흡기팬(210), 배기팬(230) 및 공급팬(220)이 구비되어 있다.In the housing 100, an intake port through which air of the indoor swimming pool is sucked and an exhaust port and a supply port for supplying air to the indoor pool are formed, and an intake fan 210 and an exhaust fan 230 are formed at the intake port, the exhaust port and the supply port, respectively. And a supply fan 220 is provided.

도 2를 참조하면, 흡기팬을 통해 하우징 내부로 들어온 공기 중 일부는 배기팬(230)을 통하여 수영장 외부로 빠져 나가고, 나머지는 증발기 방향으로 들어간다. 제어부에서는 배기팬(230)을 제어하여 곧바로 빠져나가는 공기의 양을 제어하며, 상기 배기팬(230)을 통해 빠져나가는 공기는 흡기구를 통해 들어온 공기의 0~30%로 제어되는 것이 바람직하다.Referring to FIG. 2 , some of the air that has entered the housing through the intake fan is discharged to the outside of the swimming pool through the exhaust fan 230 , and the rest enters the evaporator. The control unit controls the exhaust fan 230 to control the amount of air that immediately exits, and the air exiting through the exhaust fan 230 is preferably controlled to be 0 to 30% of the air entering through the intake port.

한편, 제어부에서는 증발기와 응축기 사이에 구비되는 제2흡입팬(240)을 통해 수영장 외부의 공기를 하우징 내부로 투입시킨다. 이렇게 함으로써 신선한 공기를 유지할 수 있으며, 제어부에서는 배기팬(230) 및 제2흡입팬(240)을 연동하여 제어함으로써 공기순환을 원활하게 할 수 있다.Meanwhile, the control unit introduces air from the outside of the swimming pool into the housing through the second suction fan 240 provided between the evaporator and the condenser. In this way, fresh air can be maintained, and the control unit can control the exhaust fan 230 and the second suction fan 240 in conjunction to facilitate air circulation.

즉, 제어부에서는 수영장 내부에 설치되는 공기질센서에 의해 실내의 CO2량이 설정치보다 높은 경우 배기팬(230) 및 제2흡입팬(240)을 구동시켜 일부의 공기를 수영장 외부로 배출시킴과 동시에 수영장 외부의 공기를 하우징 내부로 들여온다. 상기 공기질센서는 온도,습도,이산화탄소,유기화합물 및 미세먼지를 측정할 수 있는 센서로 구비되는 것이 바람직하다. That is, when the amount of CO 2 in the room is higher than the set value by the air quality sensor installed inside the swimming pool, the control unit drives the exhaust fan 230 and the second suction fan 240 to discharge some air to the outside of the swimming pool and at the same time Brings outside air into the housing. The air quality sensor is preferably provided as a sensor capable of measuring temperature, humidity, carbon dioxide, organic compounds and fine dust.

한편, 수영장 내부의 공기를 급격하게 냉방 또는 난방시켜야할 필요가 있을 경우에 제어부에서는 배기팬(230) 및 제2흡입팬(240)을 닫고 흡입구를 통해 투입되는 공기를 전부 증발기 방향으로 보내게 된다.On the other hand, when it is necessary to rapidly cool or heat the air inside the swimming pool, the control unit closes the exhaust fan 230 and the second suction fan 240 and sends all the air introduced through the suction port toward the evaporator. .

상기 증발기(110)는 하우징(100)의 흡기팬(210) 부근에 설치되어 상기 하우징(100)으로 흡입된 공기가 증발기(110)를 통과하게 된다.The evaporator 110 is installed near the intake fan 210 of the housing 100 so that the air sucked into the housing 100 passes through the evaporator 110 .

상기 압축기(120), 매질변경열교환부(710), 제2매질히터부(730), 팽창밸브(150) 및 증발기(110) 등은 냉매관(300)으로 연결되어 있으며, 상기 냉매관(300) 내부에는 기화 및 액화가 비교적 용이한 프레온가스와 같은 냉매가 들어 있다. The compressor 120 , the medium change heat exchange unit 710 , the second medium heater unit 730 , the expansion valve 150 , and the evaporator 110 are connected by a refrigerant pipe 300 , and the refrigerant pipe 300 ) contains a refrigerant such as Freon gas, which is relatively easy to vaporize and liquefy.

상기 증발기(110)에서는 저온,저압의 냉매가 지나가기 때문에 상기 흡기팬(210)을 통해 흡입된 수영장 내부의 공기는 상기 증발기(110)를 통과하면서 급격하게 온도가 낮아져 공기 중에 있던 수증기가 응결되어 액화상태로 된다. 이렇게 하여 상기 증발기(110)를 통과한 공기는 습도가 낮아지게 되며, 액화상태로 된 수증기는 다시 수영장으로 보내지거나 외부로 배출된다.Since low-temperature and low-pressure refrigerant passes through the evaporator 110 , the air inside the swimming pool sucked through the intake fan 210 is rapidly lowered in temperature while passing through the evaporator 110 , so that water vapor in the air is condensed and liquefied. to be in a state In this way, the humidity of the air that has passed through the evaporator 110 is lowered, and the liquefied water vapor is sent back to the swimming pool or discharged to the outside.

상기 압축기(120)는 작은 용량부터 큰 용량까지 각각 용량이 다른 복수 개의 압축기가 사용될 수 있으며, 각각의 압축기는 실내부하의 변동에 따라 제어될 수 있다. 온도, 습도의 실내 부하가 적을 경우 작은 용량의 압축기를 사용하게 되며, 온도, 습도의 실내부하가 클 경우 큰 용량의 압축기를 사용하는 것이 바람직하다.As the compressor 120 , a plurality of compressors having different capacities ranging from a small capacity to a large capacity may be used, and each compressor may be controlled according to a change in an indoor load. When the indoor load of temperature and humidity is small, a small capacity compressor is used, and when the indoor load of temperature and humidity is large, it is preferable to use a large capacity compressor.

구체적으로, 제어부에서는 3단계로 부하 설정치가 구획되어 있으며, 실내부하가 1단계 설정치보다 작을 경우 작은 용량의 압축기만 가동시키고, 실내부하가 1단계 설정치 이상 2단계 설정치 미만인 경우 작은 용량의 압축기를 정시시킴과 동시에 큰 용량의 압축기를 가동시키며, 실내부하가 2단계 설정치 이상인 경우 작은 용량과 큰 용량의 압축기를 모두 가동시킨다.Specifically, the control unit divides the load set value into three stages. When the indoor load is smaller than the first stage set value, only a small capacity compressor is operated, and when the indoor load is more than the first stage set value and less than the second stage set value, the small capacity compressor is scheduled At the same time, a large capacity compressor is operated, and both small and large capacity compressors are operated when the indoor load is higher than the 2-stage set value.
