이와같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
본 발명은 먼저 냉방시를 설명하기 위하여 도 1을 발췌한 도 2를 참조하여 설명한다.The present invention will first be described with reference to FIG. 2 taken from FIG. 1 to explain the cooling time.
실외기(10)에서 발생한 냉매가스는 냉매가스 제 1유도관(11)을 따라 제 1 팽창밸브(20)의 제 1모세관(22)을 통과하여 예열되면서 이 예열된 냉매가스가 냉매가스 제 2유도관(23)을 통하여 실내기(30)로 들어가 열교환이 일어난다.The refrigerant gas generated in the outdoor unit 10 is preheated through the first capillary tube 22 of the first expansion valve 20 along the refrigerant gas first induction pipe 11, and the preheated refrigerant gas is the refrigerant gas second induction. The heat exchange occurs by entering the indoor unit 30 through the pipe 23.
이와같이하여 열교환이 일어난 실내기(30)내의 냉매가스는 리턴냉매가스 제 1유도관(31)을 통하여 린턴되면서 제 1팽창밸브(20)의 제 1케이스(21)를 통과하여 예열이 되고, 이 예열된 냉매가스가 리턴냉매가스 제 2유도관(32)을 통하여 압축기(40)로 들어간다.In this way, the refrigerant gas in the indoor unit 30 in which heat exchange has been performed is preheated by passing through the first case 21 of the first expansion valve 20 while being returned through the return refrigerant gas first induction pipe 31. The refrigerant gas thus obtained enters the compressor 40 through the return refrigerant gas second induction pipe 32.
상기 압축기(40)로 들어간 냉매가스는 압축.승압하고 냉각해서 리턴냉매가스 제 3유도관(43)을 통하여 응축기인 실외기(10)로 들어가 응축된다.The refrigerant gas entering the compressor 40 is compressed, boosted and cooled to enter the outdoor unit 10 as a condenser through the return refrigerant gas third induction pipe 43 and condensed.
이와같은 사이클로 인하여 냉방이 계속적으로 진행된다.This cycle causes cooling to continue.
또한 본 발명의 난방시는 도 1을 발췌한 도 4를 참조하여 설명한다.In addition, the heating time of the present invention will be described with reference to FIG.
실외기(10)에서 발생한 냉매가스는 냉매가스 제 3유도관(12)을 통하여 냉매가스가 제 2팽창밸브(24)의 제 2케이스(25)내를 통하여 예열되면서 냉매가스 제 4유도관(27)을 따라 압축기(40)로 들어가 압축.승압되고, 이는 실내기(30)로 들어가 열교환된다.The refrigerant gas generated in the outdoor unit 10 is preheated through the refrigerant gas third induction pipe 12 through the inside of the second case 25 of the second expansion valve 24. Into the compressor (40) is compressed and boosted, which enters the indoor unit (30) and is heat exchanged.
그후 실내기(30)에서 열교환된 냉매가스는 리턴 냉매가스 제 4유도관(13)을 통하여 제 2팽창밸브(24)의 제 2케이스(25)내에 설치된 제 2모세관(26)을 통과하면서 리턴 냉매가스 제 5유도관(33)을 따라 실외기(10)로 들어간다.Then, the refrigerant gas heat-exchanged in the indoor unit 30 passes through the second capillary tube 26 installed in the second case 25 of the second expansion valve 24 through the return refrigerant gas fourth induction pipe 13 and returns the refrigerant. The gas enters the outdoor unit 10 along the fifth induction pipe 33.
이와같은 사이클은로 난방이 계속적으로 일어난다.Cycles like this continue to generate furnace heating.
단 상기 냉방시에는 난방을 할 때에 유도되는 각각의 유도관에 설치된 밸브를 크로즈하면 되고, 난방시에는 냉방가스가 흐르는 각 유도관의 밸브를 크로즈하면 된다.However, at the time of cooling, the valve provided in each induction pipe guide | induced when heating may be closed, and at the time of heating, the valve of each induction pipe through which cooling gas flows may be closed.
그리고 제 1팽창밸브(20)내에 설치된 제 1모세관(22)과 제 2팽창밸브(24)내에 설치된 제 2모세관(26)의 직경을 서로 달리한 이유는 냉방을 이루는 냉매가스가 흐를 때 에는 냉매가스가 저온이기 때문에 냉매압이 적어 제 1모세관(22)의 직경을 작게한것이고, 제 2모세관(26)의 직경을 크게한 이유는 난방시 냉매가스의 냉매압이 크기 때문이다.The reason why the diameters of the first capillary tube 22 installed in the first expansion valve 20 and the second capillary tube 26 provided in the second expansion valve 24 are different from each other is that the refrigerant when the refrigerant gas for cooling flows. Since the gas is low temperature, the refrigerant pressure is small and the diameter of the first capillary tube 22 is reduced, and the diameter of the second capillary tube 26 is increased because the refrigerant pressure of the refrigerant gas during heating is large.
한편 각각의 모세관(22)(26)외부에 각각의 케이스(21)(25)를 설치한 이유는 각각의 냉매가스가 린턴될 때 상기 각각의 케이스(21)(25)내를 통과하면서 예열되어 에너지 손실을 최대로 줄이고자 한 것이다.On the other hand, the reasons for installing the respective cases 21 and 25 outside the respective capillaries 22 and 26 are preheated while passing through the respective cases 21 and 25 when the respective refrigerant gas is to be returned. The goal is to minimize energy loss.
그리고 압축기(40)의 입,출측에 설치된 각각의 압력게이지(41)(42)는 압축기(40)로 들어오고 나가는 냉매가승의 압을 적정하게 조정하기 위하여 설치하였다.The pressure gauges 41 and 42 respectively installed at the inlet and outlet sides of the compressor 40 were installed to appropriately adjust the pressure of the refrigerant riding in and out of the compressor 40.
이상과 같은 본 발명은 냉방시와 난방시에 냉매가스를 각기 다른 유도관으로 유도시킴과 동시에 각각의 팽창밸브를 사용하기 때문에 열효율 향상시켜 소비자의 욕구를 충족시킴은 물론 에너지를 절약할 수 있는 효과가 있다.As described above, the present invention induces refrigerant gas to different induction pipes during cooling and heating, and at the same time uses expansion valves, thereby improving thermal efficiency and satisfying consumer demands, as well as saving energy. There is.
