Through the refrigerant flow regulator (F) through No. 10 and No. 10 pipes, expand and evaporate to the coil type heat exchanger (B) through No. 12 pipe, solenoid valve (S2), and expansion valve (e2) After cooling, pipe 3 and 14 , If the suction pressure is normal in the pressure regulating valve (P / V) via the 17th pipe, enter the liquid separator (G) through the 18th pipe and suck it into the compressor (A). Inlet into the liquid separator (G) via the auxiliary hot water tank (J) through the pipe 19, and sucked into the compressor (A).

이때 현장 등의 실내온도가 냉방 시의 적정온도가 되거나 냉방을 시행하지 않을 때는 코일 형 열교환기(B)의 휀(FAN)을 정지시키고 12번 배관의 솔레노이드 밸브(S2)를 닫고 13번 배관의 솔레노이드 밸브(S3)를 열어 팽창밸브 (e3)를 통해 증발기 용 판형 열교환기(I)에서 냉매를 팽창 증발시키고 순환펌프(P)를 가동시켜 물 용 솔레노이드 밸브(SW2)를 열어 증발기 용 판형 열교환기(I)에서 냉매를 증발시켜 냉수탱크(M)에 냉수를 생산, 저장한다.At this time, if the room temperature at the site is the proper temperature at the time of cooling or if the cooling is not performed, stop the fan (FAN) of the coil type heat exchanger (B), close the solenoid valve (S2) of pipe No. 12, and Open the solenoid valve (S3) to expand and evaporate the refrigerant in the evaporator plate heat exchanger (I) through the expansion valve (e3) and activate the circulation pump (P) to open the solenoid valve (SW2) for water to open the plate heat exchanger In (I), the refrigerant is evaporated to produce and store cold water in the cold water tank (M).

만약 외부온도가 급상승하여 코일 형 열교환기(C)에서의 응축이 불충분 하여 응축 압력이 상승할 경우에는 한시적으로 솔레노이드 밸브(S4)를 열어 10-1번 배관을 경유 팽창밸브(e4)를 통해 냉매유량 조절기(F)에 냉매를 팽창 증발시켜 10번 배 관을 통해 12번, 13번 배관으로 흐르는 냉매를 재 응축시켜 응축압력을 조절하여 팽창밸브 (e2), 팽창밸브 (e3)를 통해 증발하는 냉매의 증발을 돕고 자신은 냉매유량 조절기(F)에 저장, 계통내의 냉매량을 압력에 따라 자동 조절하고 동절기 시 또는 냉방 시 응축압력이 떨어지면 냉매유량 조절기(F)와 액 분리기(G)로의 흡입 압력차에 따라 16번 배관을 거쳐 체크밸브 C3를 경유하여 17번 배관에 연결, 압축기에 재 흡입되어 동절기나 응축압력 하락 시 적정 냉매량을 유지 시켜 기계의 운전을 원활하게 조정한다. 냉방 시는 10번 배관을 통해 흐르는 냉매의 응축 열량으로 냉매유량 조절기(F)내의 압력이 상승 액 분리기(G)내의 흡입압력과의 차에 따라 재유입이 쉬우나 동절기 시에는 냉매유량 조절기(F)내의 압력이 낮아 재 유입이 어려우므로냉매유량 조절기(F)에 열선을 설치 냉매유량 조절기(F)내의 압력을 상승시켜 액 분리기(G)로의 유입을 도와준다.If the condensation pressure increases due to insufficient condensation in the coil type heat exchanger (C) due to a sudden rise in external temperature, the solenoid valve (S4) is temporarily opened to open the refrigerant via the expansion valve (e4) via the 10-1 pipe. Expansion and evaporation of the refrigerant in the flow controller (F) to re-condensing the refrigerant flowing through the pipe number 10 and 12, pipe 13 and control the condensation pressure to evaporate through the expansion valve (e2), expansion valve (e3) It helps to evaporate the refrigerant and saves it in the refrigerant flow regulator (F), and automatically adjusts the amount of refrigerant in the system according to the pressure and the suction pressure to the refrigerant flow regulator (F) and the liquid separator (G) when the condensation pressure drops during winter or cooling. Depending on the car, it is connected to pipe 17 through check valve C3 through pipe 16, and re-inhaled by the compressor to maintain the proper amount of refrigerant during winter or when the condensation pressure drops to smoothly adjust the operation of the machine. When cooling, condensation heat of refrigerant flowing through pipe No. 10, the pressure in the refrigerant flow regulator (F) is easy to reflow depending on the difference between the suction pressure in the liquid separator (G), but during the winter, the refrigerant flow regulator (F) Since the pressure inside is difficult to re-introduce, the heating wire is installed in the refrigerant flow rate controller (F) to increase the pressure in the refrigerant flow rate controller (F) to help the flow into the liquid separator (G).

그리고 현장 등에 냉방운전을 시행하지 않거나, 실내온도가 냉방 모드 시의 적정온도에 도달하면 냉수 모드로 전환시켜 냉수탱크(M)에 냉수를 생산, 저장한 냉수를 순환시켜 사무실, 식당의 각방, 주방 등 필요한 곳에 휀 코일 유니트 등 적절한 열교환기를 사용하여 냉방을 실시하고 온수도 사용한다.If the indoor temperature does not perform the cooling operation or if the indoor temperature reaches the proper temperature in the cooling mode, it is switched to the cold water mode to circulate the cold water produced and stored in the cold water tank (M) in each room of the office, restaurant, and kitchen. If necessary, use an appropriate heat exchanger, such as a coil unit, to cool and use hot water.
