일반적으로 에어컨디셔너는 실외에 실외기를 설치되고, 실내에 실내기를 설치되며, 실외기와 실내기 사이에는 냉매관이 배관된다. 근래에 들어서는 실외기의 성능이 향상됨에 따라 1대의 실외기에 여러 대의 실내기가 장착되고, 각각의 실내기마다 리모컨이나 제어기와 같은 제어수단으로 각 제어하는 시스템에어컨이 각광을 받고 있다. 상기와 같은 시스템에어컨의 원리는, 1대의 실외기에서 배관되는 동관이 분배기를 통하여 다수의 동관으로 배관되며, 그 각각의 배관은 다수의 실내기에 각각 연결되어, 실외기에서 차가워진 냉매는 동관을 통하여 상기 각각의 실내기에 공급되어 시원한 바람을 공급하게 된다. 이러한, 시스템에어컨은 1대의 실외기에 다수의 실내기를 연결하여 사용할 수 있으므로, 공간의 활용도가 우수한 동시에 소모되는 에너지 효율을 극대화하는 효과가 있다. 여기서, 상기 분배기의 하우징에 결합되어, 일단은 분배기에 내장된 팽창밸브와 연결된 동관의 끝단과 결합되며, 타단은 증발기와 연결되는 동관의 일단이 결합되어 실내기에서 공급되는 냉매를 실외기로 유통시키는 동관을 상호 연결해주는 매개체인 날개소켓은 통상적으로 고가의 황동으로 제조됨으로 제품의 단가가 높아지는 문제점이 있었다. 또한, 원재료를 고가인 황동을 사용하여 제품의 단가가 높아짐으로, 제품의 가격경쟁력은 낮아지는 부가적인 문제점이 있었다.In general, an air conditioner is an outdoor unit installed outdoors, an indoor unit is installed indoors, a refrigerant pipe is piped between the outdoor unit and the indoor unit. Recently, as the performance of the outdoor unit is improved, several indoor units are installed in one outdoor unit, and each air conditioner has been in the spotlight for each indoor unit to be controlled by a control means such as a remote controller or a controller. The principle of the air conditioner as described above, the copper pipe piped in one outdoor unit is piped to a plurality of copper pipes through a distributor, each of the pipes are connected to a plurality of indoor units, respectively, the refrigerant cooled in the outdoor unit is the copper pipe through the Each indoor unit is supplied with cool air. Such a system air conditioner can be used by connecting a plurality of indoor units to one outdoor unit, thereby maximizing the utilization of space and maximizing energy efficiency. Here, it is coupled to the housing of the distributor, one end is coupled to the end of the copper tube connected to the expansion valve built in the distributor, the other end is coupled to one end of the copper tube connected to the evaporator is coupled to distribute the refrigerant supplied from the indoor unit to the outdoor unit Wing socket, which is a medium for interconnecting the wires, is usually made of expensive brass, resulting in a problem that the cost of the product increases. In addition, since the price of the product is increased by using expensive brass as a raw material, there is an additional problem that the price competitiveness of the product is lowered.
에어컨은 에어컨디셔널(Air Conditioner)의 약자로 공기조화장치(냉난방장치)를 의미하는데 이것은 실내를 쾌적하고 안락한 조건에 맞도록 온도, 습도, 공기청정도 등을 일정하게 조절하는 시스템이다. Air conditioner stands for Air Conditioner (Air Conditioner), which is a system that constantly adjusts the temperature, humidity, air cleanliness, etc. to suit the comfortable and comfortable conditions of the room.
일반적으로 공기조화 시스템으로는 냉난방장치만을 생각하기 쉽지만 온도조절장치, 습도조절장치, 공기여과장치, 내부공기 순환장치 등 여러 가지 공기조화 장치가 있다.Generally, it is easy to think of only air-conditioning system as an air conditioning system, but there are various air conditioners such as a temperature controller, a humidity controller, an air filter, and an internal air circulation system.
원래 에어컨의 기본 원리는 하나이다. 즉 냉매를 압축, 응축, 팽창, 증발 이렇게 4단계이다. 단지 이것을 응용하고 그 기능을 보완하여 히트펌프식이나 시스템 에어컨 등으로 나뉘어 이름을 붙이고 그 기능을 설정해 준다. 히트펌프식이란 응축기(실외기)와 증발기(실내기)의 기능을 서로 교체하여 여름에는 정식 에어컨이었다가 겨울에는 그 기능을 서로 바꾸는 것이다. 단지 난방능력이 다소 부족하여 겨울 난방시에 -5 이하로 낮은 기온에서는 전열코일로 난방 열량을 조금 보충해 주는 것 이다.The basic principle of the original air conditioner is one. The refrigerant is compressed, condensed, expanded, and evaporated in four stages. It just applies this and complements its function, divides it into heat pump type or system air conditioner, and sets its function. The heat pump type replaces the functions of the condenser (outdoor unit) and the evaporator (indoor room) so that it is a formal air conditioner in the summer and the function in the winter. However, the heating capacity is somewhat insufficient, and at low temperatures below -5 during winter heating, electric heating coils supplement the heating amount.
시스템 에어컨은 실외기 하나에 실내기를 여러 대 붙여서 사용하는 것으로 실내기를 천정 등에 설치하여 그 설치면적을 줄이는 것이다. 하나의 실외기에서 나오는 냉매관에서 분배기를 통하여 여러 개로 분리하고 각각의 가치관에 팽창벨브를 부착하여 실내기를 여러 대를 병렬로 운전하는 것이다. 난방은 히트펌프식을 감안하고 역싸이클로 하는 것이며 물론 난방부하에 그 능력이 부족한 부분은 전열로 커버한다. 에어컨회사에서 모두 시스템에어컨을 생산하는 이유도 이와 같다.System air conditioner uses several indoor units attached to one outdoor unit and installs the indoor unit on the ceiling to reduce the installation area. In the refrigerant pipe from one outdoor unit, it is separated into several through a distributor and an expansion valve is attached to each value pipe to operate several indoor units in parallel. The heating is performed in reverse cycle in consideration of the heat pump type, and of course, the portion of the heating load lacking in capacity is covered by electric heat. This is why all air conditioners produce system air conditioners.
팽창밸브는 증발기 입구에 설치되어 리시버 드라이어에서 들어온 고압의 액체 냉매를 얇은관을 통해 무화시켜 증발기로 보내는 작용을 한다. 에어컨의 열부하는 외기의 온도, 습도 등에 따라 변화되며 그러한 부하의 변화에 알맞게 대응하기 위해서 냉방 싸이클 내의 냉매량을 조정하는 것이 필요하다. 이러한 목적으로 팽창밸브를 사용한다. 만일 열부하가 증가하고 냉매의 흐름이 일정하다면 냉매는 증발기 출구에 도달했을 때는 완전히 증발되어 있을 것이다. 그이상의 열부하가 걸린다 해도 냉방을 할 수 있지만 냉매의 증발 온도는 증발점 온도보다 높게 되며 이러한 상태를 과열상태라 한다. 그러나 증발점이 높으면 컴프레서 압축부에서 냉매의 온도가 이상 고압시 컴프레서 실린더 에바의 출구부에 도달했을 때에도 완전히 기화되지 않으며 컴프레서에 액체 냉매 상태로 보내지게 되고 이 액체 냉매는 컴퓨레서 밸브를 손상시킨다. 따라서 팽창밸브는 열부하의 변화에 따라 알맞은 상태에서 비열점이 유지도록 에바에 공급되는 냉매의 양을 조절한다.The expansion valve is installed at the inlet of the evaporator to atomize the high pressure liquid refrigerant from the receiver dryer through the thin tube and send it to the evaporator. The heat load of the air conditioner changes according to the temperature, humidity, etc. of the outside air, and it is necessary to adjust the amount of the refrigerant in the cooling cycle in order to cope with such a change in the load. Expansion valves are used for this purpose. If the heat load increases and the flow of refrigerant is constant, the refrigerant will be completely evaporated when it reaches the evaporator outlet. Cooling can be achieved even if the heat load is higher than that, but the evaporation temperature of the refrigerant is higher than the evaporation point temperature. However, if the evaporation point is high, even when the temperature of the refrigerant in the compressor compression section reaches the outlet of the compressor cylinder eva at high pressure, it is not completely vaporized and is sent to the compressor as a liquid refrigerant, which damages the compressor valve. Therefore, the expansion valve adjusts the amount of refrigerant supplied to the EVA to maintain the non-heat point in a proper state according to the change of the heat load.
한편, 분배기의 하우징에 결합되어, 일단은 분배기에 내장된 팽창밸브와 연결된 동관의 끝단과 결합되며, 타단은 증발기와 연결되는 동관의 일단이 결합되어 실내기에서 공급되는 냉매를 실외기로 유통시키는 동관을 상호 연결해주는 매개체인 날개소켓은 통상적으로 고가의 황동으로 제조됨으로 제품의 단가가 높아지는 문제점이 있었다.On the other hand, it is coupled to the housing of the distributor, one end is coupled to the end of the copper tube connected to the expansion valve built in the distributor, the other end is coupled to one end of the copper tube connected to the evaporator is coupled to the copper tube for circulating the refrigerant supplied from the indoor unit to the outdoor unit Wing sockets, which are interconnecting mediums, are usually made of expensive brass, resulting in higher unit costs.
또한, 원재료를 고가인 황동을 사용하여 제품의 단가가 높아짐으로, 제품의 가격경쟁력은 낮아지는 부가적인 문제점이 있었다.In addition, since the price of the product is increased by using expensive brass as a raw material, there is an additional problem that the price competitiveness of the product is lowered.
