Between the condenser and the cooling coil, the receiver 110, a refrigerant filter for filtering foreign matter from the refrigerant, a liquid level gauge for observing the inside, and a solenoid valve for opening and closing are sequentially installed. And this cycle is repeated to cool the room.

한편 상기 냉각코일(20) 또는 가열코일(10)을 거친 공기는 다시 공기조화기 내부에 설치된 전기히터(80)에 의해 가열되어 상대습도가 조절이 되는 것으로, 냉각제습은 외기의 절대습도는 감소시켜 공기자체 수분량은 감소시키나, 온도가 내려가므로 상대습도는 상승하는 불안정한 요소가 있으므로, 이를 보완하기 위해 토출측에 전기히터를 설치하면 공급되는 공기의 온도는 상승하나, 상대습도는 감소하게 되는 효과가 있다.     Meanwhile, the air passing through the cooling coil 20 or the heating coil 10 is heated by an electric heater 80 installed inside the air conditioner to control relative humidity, and the cooling and dehumidification decreases the absolute humidity of the outside air. The water content of the air itself is reduced, but since the temperature is lowered, there is an unstable factor in which the relative humidity rises. Therefore, if an electric heater is installed on the discharge side to compensate for this, the temperature of the supplied air rises, but the relative humidity decreases. have.

그리고 히터 대신 핫가스 바이패스 라인을 설치하여 핫가스를 가열코일에 공급하여 실내에 공급되는 공기의 온도를 상승시키는 방법이 있다.     In addition, there is a method of increasing the temperature of the air supplied to the room by supplying a hot gas to the heating coil by installing a hot gas bypass line instead of the heater.

구체적으로 핫가스 바이패스회로에 대해 기술하면, 상기 가열코일(10)과 4웨이밸브(40) 사이에는 별도로 핫가스바이패스회로를 연결하여, 4웨이밸브(40)에서 압축기(30)를 거친 냉매가 일부는 분기되어 가열코일(10)로 인입되어, 실내에 공급되는 공기의 온도는 상승시키면서 상대습도는 감소하게 되며, 상기 가열코일(10)에서 되돌아오는 냉매는 응축기(100)를 거쳐온 냉매와 수액기(110)에서 혼합되어 냉각코일(20)로 인입된다. 냉각코일을 거친 냉매는 4웨이밸브로 되돌아 온 후 다시 압축기를 거쳐 압축된 후, 앞서와 마찬가지로 일부 냉매는 가열코일로 인입되고, 나머지는 응축기를 거치게 되며, 수액기에서 냉매가 혼합된다.     Specifically, when describing the hot gas bypass circuit, a hot gas bypass circuit is separately connected between the heating coil 10 and the four-way valve 40 to pass through the compressor 30 at the four-way valve 40. Part of the refrigerant is branched and introduced into the heating coil 10, the relative humidity decreases while the temperature of the air supplied to the room is increased, and the refrigerant returned from the heating coil 10 passes through the condenser 100. The refrigerant is mixed with the receiver 110 and introduced into the cooling coil 20. After the refrigerant has passed through the cooling coil, the refrigerant is returned to the four-way valve and then compressed again through the compressor, and as in the past, some refrigerant is introduced into the heating coil, and the others are passed through the condenser, and the refrigerant is mixed in the receiver.

핫가스바이패스회로는 핫가스 바이패스 솔레노이드 밸브를 개폐함으로써 냉방제습을 제어할 수 있다. 핫가스 바이패스 솔레노이드 밸브를 열게 되면, 난방코일에 뜨거운 냉매가 인입되어 냉각코일에 의해 냉각제습된 공기를 가열 상대습도를 낮추어 공급하게 된다.     The hot gas bypass circuit can control the cooling and dehumidification by opening and closing the hot gas bypass solenoid valve. When the hot gas bypass solenoid valve is opened, hot refrigerant is introduced into the heating coil to supply air dehumidified by the cooling coil to lower heating relative humidity.

냉방제습이 가동되는 습도는 상대습도가 80%일 경우이며, 상대습도가 42%이하로 떨어지면 냉방제습을 멈추게 된다. Humidity for cooling and dehumidification is when the relative humidity is 80%, and when the relative humidity drops below 42%, the cooling dehumidification is stopped.

그리고 상기 냉각코일(20)과 가열코일(10) 사이에는 수분포집기(120, WATER CATCHER)가 설치되어 있어서 수분을 제거한다.     In addition, a water collector 120 (WATER CATCHER) is installed between the cooling coil 20 and the heating coil 10 to remove moisture.

그리고 본발명은 상기 응축기(100) 곁에는 제상히터(130)가 설치되어 있어서 겨울철 히터펌프운전식 응축기의 결빙을 방지할 수 있기 때문에, 본발명이 동절기에 히트펌프방식으로 냉난방 및 제습이 가능한 것이다.     And the present invention is because the defrost heater 130 is installed next to the condenser 100 can prevent the freezing of the heater pump operation type condenser in winter, the present invention can be heated and dehumidified by heat pump method in winter .

본발명은 주로 조선소 등의 대형 페이트숍을 냉난방제어하는 것으로, 이 때 냉방시의 경우는 외기는 35℃로 보며, 출구온도는 26℃이며 상대습도는 42%로 정한다. 이때의 냉각코일 출구 목표온도는 15℃로 정한다.      The present invention mainly controls the heating and cooling of large fat shops such as shipyards. At the time of cooling, the outside air is regarded as 35 ℃, the outlet temperature is 26 ℃ and the relative humidity is set to 42%. The cooling coil outlet target temperature at this time is set to 15 ° C.

그리고 본발명은 상기와 같은 냉난방회로는 2개를 동시에 설치하며, 그 운전은 하나만을 가동할 수 있다. 각각의 압축기는 개별 냉방, 난방이 가능하다. 그리고 냉각, 제습 운전시 운전시간별로 교번운전이 가능하다.      And the present invention is installed in the two heating and cooling circuits at the same time, the operation can operate only one. Each compressor can be individually cooled and heated. Alternating operation is possible by operation time during cooling and dehumidification operation.

따라서 본발명은 이동형 냉각제습기에 4웨이밸브를 설치하여 동작을 제어함으로써 냉난방 에너지 효율이 개선되며, 냉난방시스템이 간단하며 조작이 편리하며, 또한 핫가스바이패스회로를 설치하여 냉방시도 제습이 용이하다.     Therefore, the present invention improves heating and cooling energy efficiency by installing a 4-way valve in a mobile cooling dehumidifier, and improves heating and cooling energy efficiency. The heating and cooling system is simple and convenient to operate. Also, by installing a hot gas bypass circuit, it is easy to dehumidify when cooling. .
