제 2 도는 본 고안에 따른 냉매 기화열 및 증발열 조절장치를 도시한 상태도2 is a state diagram showing a refrigerant vaporization heat and evaporation heat control apparatus according to the present invention
제 3 도는 본 고안의 요부를 확대 도시한 배관도3 is an enlarged view of the main part of the present invention
본 고안은 냉각기 싸이클에 사용되는 냉매가스의 온도를 냉각보상 시킬 수 있도록 한것에 관한 것으로써, 더욱 구체적으로는 증발기를 거쳐 압축기로 순환 유입되는 수소화불화탄소(HCFC-22) 냉매가스의 온도를 낮게하여 줌으로써 압축기의능력향상과, 수명을 대폭연장 시킬 수 있도록 한것에 주안점을 둔 것이다.The present invention relates to the cooling compensation of the temperature of the refrigerant gas used in the cooler cycle, and more specifically, to lower the temperature of the hydrogen fluorocarbon (HCFC-22) refrigerant gas circulated into the compressor through the evaporator. The main focus is on improving the compressor's capacity and prolonging its service life.
일반적인 냉각기 싸이클 구조는 첨부된 도면 제 1 도에 도시한 바와같이 증발기(100)를 통과한 저압의 기체냉매 가스가 압축기(200)를 거치며 고압기체로 변환되고 응축기(300)로 유입되어 고압의 기체가 액체상태로 재차 변환되어 수액기(400)와 팽창밸브(401)를 통해 증발기(100)를 거치며, 다시 저기압의 기체가스로 변화 순환되는 것으로써, 상기한 바와 같은 일반적인 냉각 싸이클에 사용되는 냉매가스는 염화불화탄소(CFC-502)로써, 이는 오존층 파괴의 정도가 매우 높아, 오존층 보호를 위해 국제환경협약에서 사용이 금지되는 냉매로 인해 가격폭등과 구득난으로 수요자가 많은 어려움을 겪는 실정이다.The general cooler cycle structure is a gas refrigerant gas of low pressure passing through the evaporator 100 is converted to a high pressure gas through the compressor 200 and introduced into the condenser 300 as shown in FIG. Is converted back into the liquid state and passed through the evaporator 100 through the receiver 400 and the expansion valve 401, and is circulated again into a low-pressure gas gas, the refrigerant used in the general cooling cycle as described above The gas is chlorofluorocarbon (CFC-502), which has a very high degree of destruction of the ozone layer. As a result, the price of the refrigerant is banned by the international environmental convention for the protection of the ozone layer.
상기와 같은 문제점을 해결하기 위해 냉매가스를 오존층의 파괴정도가 낮은 수소화불화탄소(HCFC-22)로 교체 사용시 요구되나, 이는 수소화불화탄소(HCFC-22)가스를 기존의 냉각기 싸이클에 사용할 경우 증발기(100)를 통과하는 도출가스가 매우 고열인 상태로 압축기(200)내부로 유입됨에 따라 압축기내의 냉동유가 탄화되어 냉각기가 쉽게 마모되어 기기의수명이 단축되는 한편 압축기로 유입되는 냉매가스의 희소로 압축기가 공회전 하는률이 많아 냉동능력이 매우 낮아 사용하지 못하는 문제점이 있었다.In order to solve the above problems, it is required to replace refrigerant gas with hydrofluoric carbon (HCFC-22), which has a low degree of destruction of the ozone layer. However, when using hydrofluoric carbon (HCFC-22) gas in an existing cooler cycle, an evaporator is used. As the derivation gas passing through the (100) is introduced into the compressor 200 in a very high temperature state, the refrigeration oil in the compressor is carbonized and the cooler is easily worn, shortening the life of the device and reducing the scarcity of refrigerant gas flowing into the compressor. Since the compressor has a high idling rate, there was a problem that the refrigeration capacity is very low and cannot be used.
따라서 본 고안은 상기한바와 같은 종래의 문제점을 해결하기 위한 것으로써, 본 고안의 목적은 기존의 냉각싸이클에 사용되는 냉매를 오존층 파괴가 낮은 수소불화탄소(HCFC-22)를 교체시키더라도, 염화불화탄소(CFC-502)냉매와 같은 냉각효과를 얻을 수 있음은 물론, 냉동유 탄화방지와 도출가스 온도의 상승방지로 냉동기 효율증대 및 오존층 파괴와 같은 환경오염을 예방할 수 있는 냉각기의 싸이클의 냉매 기화열 및 증발량 조절장치를 제공함에 있다.Therefore, the present invention is to solve the conventional problems as described above, the object of the present invention is to replace the refrigerant used in the existing cooling cycle with hydrofluoric carbon (HCFC-22) low ozone layer destruction, even if the chloride Cooling effect like carbon fluoride (CFC-502) refrigerant, coolant cycle of cooler cycle that can prevent freezing oil carbonization and increase of freezing gas temperature and prevent environmental pollution such as increase of freezer efficiency and destruction of ozone layer. The present invention provides an apparatus for controlling evaporation heat and evaporation amount.
이하 본 고안에 따른 냉각기 싸이클의 냉매냉 각 기화열 및 증발량 조절장치를 첨부된 도면에 의거하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the refrigerant cooling vaporization heat and evaporation amount control apparatus of the cooler cycle according to the present invention will be described in detail with reference to the accompanying drawings.

And in the conventional cooler cycle connected to the evaporator 100 through the expansion valve 401, between the evaporator 100 and the receiver 400, the refrigerant vaporization heat and evaporation amount control device 10 is installed, The main line 402 connected to the receiver 400 through the heat exchanger 50 of the control device 10 is connected to the evaporator (l00) and an expansion valve (inlet) at the inlet end 52 of the soft exchanger (50). Inlet line 40 to which the solenoid valve 42 and the safety valve 42 are connected 41 is connected to the main line 402 on the receiver side,
토출단(51)에는 저압압력조성밸브(6l)와 필터(62) 및 스톱밸브(63)를 거쳐, 상기 증발기(100)에서 압축기(200)를 연결되는 흡입라인(101)과 연결되는 토출라인(60)을 결합설치하되, 이 조절장치의 토출라인(60)상에 냉매 흐름량을 감지하는 감지기(31)를 설치하고, 이 감지기의 신호에 의해 유입라인측의 팽창밸브(41)가 개폐토록하며, 이에 바이패스라인(30)이 설치되어 토출라인(60)과 연결설치 구성된 것이다.The discharge line 51 is a discharge line connected to the suction line 101 is connected to the compressor 200 in the evaporator 100 through a low pressure pressure composition valve 6l, a filter 62 and a stop valve 63. (60) is installed in combination, and the detector 31 for detecting the amount of refrigerant flow is installed on the discharge line 60 of the adjusting device, and the expansion valve 41 on the inlet line side is opened and closed by the signal of the detector. And, this bypass line 30 is installed is configured to be connected to the discharge line 60.
