본 고안은 냉동장치의 고온가스 제상장치에 있어서 증발기를 거쳐서 돌아오는 과냉각 냉매액을 재증발시키기에 적당한 냉동장치용 액냉매의 재증발 장치에 관한 것으로, 특히 그 구조를 간단히 하여 제작단가 및 고장이 적게 할 목적으로 안출된 것이다.The present invention relates to a re-evaporation device for a liquid refrigerant for a refrigerating device suitable for re-evaporating a supercooled refrigerant liquid returned through an evaporator in a high-temperature gas defrosting device of a refrigerating device. It is intended to be small.

종래의 구성을 살펴보면 도면 제1도에서와 같이 냉매용 압축기(1), 응축기(2), 팽창밸브(3)를 거쳐 증발기(5)로 가거나 제상시에 고온가스를 바이패스 시킬 수 있는 전자변(4), 증발기(5)를 거쳐 증발기(5)를 거쳐 제상시와 냉동시 흡입냉매의 회로를 바꾸어 주는 전자변(6)(7)과 제상후 돌아오는 고압의 냉매를 저압으로 바꾸어 주는 압력조절변(8)과 저온 저압의 액냉매를 재증발시키는 서어모-뱅크(Thermo-Bank)(9)로 구성되어 있다. 여기서 서어모-뱅크(9)는 압축기에서 토출되는 관과 제상후 돌아오는 저온 저압의 액냉매가 물로써 열전달하여 열교환시키는 장치로써, 종래의 고온가스 제상방식은 제상시에 증발기(5)를 거쳐서 돌아오는 과냉각 냉매를 뜨거운 물이 저장된 서어모-뱅크(9)로 통과하게 한 후에 재증발된 가스를 압축기(1)로 흡입시키는 방식을 이용하므로써 서어모-뱅크(9)자체의 구조가 복잡하여 제작단가 및 그로인한 고장율이 높은 단점이 있으며 특히, 액냉매를 열전달체로 사용하는 간접냉각방식으로 열효율이 좋치 않으며 비정기적이기는 하지만 액냉매의 교체 등 번거로운 점이 있다.Referring to the conventional configuration, as shown in FIG. 1, an electronic valve capable of bypassing hot gas at the time of defrosting or going to the evaporator 5 through the refrigerant compressor 1, the condenser 2, the expansion valve 3, and the like ( 4), through the evaporator (5), through the evaporator (5), the electronic valve (6) (7) for changing the circuit of the suction refrigerant during defrosting and freezing, and the pressure regulating valve for changing the high-pressure refrigerant returned to low pressure after defrosting (8) and Thermo-Bank (9) for re-evaporating liquid refrigerant of low temperature and low pressure. Here, the thermo-bank 9 is a device in which a tube discharged from the compressor and a low-temperature low-pressure liquid refrigerant returning after defrosting are heat-transferd and exchanged by water. The conventional high-temperature gas defrosting system passes through an evaporator 5 during defrosting. The structure of the thermo-bank (9) itself is complicated by using a method of allowing the returning supercooled refrigerant to pass through the thermo-bank (9) where hot water is stored and then sucking the re-evaporated gas into the compressor (1). There is a disadvantage that the production cost and failure rate is high, and in particular, the indirect cooling method using the liquid refrigerant as the heat carrier is not good thermal efficiency and irregular, but there is a cumbersome point such as replacement of the liquid refrigerant.

따라서 본 고안은 이상과 같은 문제점을 해결하고자 제상후 돌아오는 고압의 냉매를 저압으로 바꾸어 주는 압력조절변을 지나 액가스 열교환기로 보내 압축기로 흡입시키게 하고 냉동운전시 토출냉매가 액가스 열교환기를 지나도록 되어 그 구성을 간단히 하면서 직접 열교환식으로 하여 그로인한 제작단가 및 고장율이 적으며 열효율이 좋게 할 목적으로 안출된 것이다.Therefore, to solve the above problems, the present invention sends a high pressure refrigerant returning to a low pressure after defrost to a liquid gas heat exchanger to be sucked into the compressor, and the discharged refrigerant passes through the liquid gas heat exchanger during refrigeration operation. It is made for the purpose of making the structure simple and direct heat exchange type, resulting in low production cost and failure rate and good thermal efficiency.

이하에서 이를 첨부도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

냉매용 압축기(1)로 부터의 냉매가 응축기(2), 팽창밸브(3)를 지나 증발기(5)와 전자변(7)을 지나 압축기(1)로 흡입됨과 동시 제상시에는 압축기(1)로 부터의 냉매를 바이패스시키는 전자변(4)과 증발기(5)를 지나 회로를 바꾸어 주는 전자변(6) 및 압력조절변(8)을 거쳐 저온 저압의 액냉매를 재증발시키도록 된 것에 있어서, 제상운전시 압력조절변(8)으로 부터의 고압가스가 액가스 열교환기(10)의 내부 열교환관(10a)을 거쳐 압축기(1)로 흡입되게 함과 동시에 냉동운전시의 냉매압축기(1)로 부터의 냉매가 액가스 열교환기(10)를 지나 응축기(2)로 가게 연결한 구성이다.The refrigerant from the compressor (1) is sucked into the compressor (1) through the condenser (2), the expansion valve (3), through the evaporator (5) and the solenoid valve (7), and to the compressor (1) during simultaneous defrosting. In which the low temperature and low pressure liquid refrigerant is re-evaporated through the electron valve 4 and the pressure regulating valve 8 which change the circuit through the electron valve 4 and the evaporator 5 which bypass the refrigerant from During operation, the high pressure gas from the pressure regulating valve (8) is sucked into the compressor (1) through the internal heat exchange tube (10a) of the liquid gas heat exchanger (10) and at the same time to the refrigerant compressor (1) during the freezing operation. The refrigerant from is passed through the liquid gas heat exchanger (10) to the condenser (2) connected to the configuration.

상기와 같은 본 고안의 작동상태를 살펴보면 도면 제2도에서와 같이, 냉동운전시에는 냉매압축기(1)에서 토출된 고온 고압의 가스는 액가스 열교환기(10)를 통과하여 응축기(2)를 지나면서 응축되어 팽창변(3)을 지나면서 저온 저압의 상태로 증발기(5)에서 증발되어 전자변(7)을 지나 냉매압축기(1)로 흡입되게 하며, 제상운전시에는 냉매압축기(1)에서 토출된 고온 고압의 가스가 전자변(4)이 열리면서 바이패스 관로를 지나, 증발기(5)로 직접 들어가 제상을 한 후 과냉각된 고압의 냉매액이 전자변(7)이 닫히고 전자변(6)이 열려서 압력조절변(8)을 통과하면서 고압으로 변하고 액가스 열교환기(10)에 들어가서 재증발되어 압축기(1)로 흡입되게 한다.Looking at the operating state of the present invention as shown in Figure 2, during the refrigeration operation, the high temperature and high pressure gas discharged from the refrigerant compressor (1) passes through the liquid gas heat exchanger (10) to condenser (2) It condenses as it passes through the expansion valve (3) and evaporates from the evaporator (5) at low temperature and low pressure to be sucked into the refrigerant compressor (1) through the electron valve (7), and discharged from the refrigerant compressor (1) during defrosting operation. After the high temperature and high pressure gas is opened, the electron valve 4 opens, passes through the bypass pipe, directly enters the evaporator 5, and defrosts. Then, the supercooled high-pressure refrigerant liquid closes the electron valve 7 and the electron valve 6 opens to adjust the pressure. As it passes through the side (8), it changes to a high pressure, enters the liquid gas heat exchanger (10), re-evaporates, and is sucked into the compressor (1).

이상과 같은 본 고안은 종래의 간접열교환방식에 비해 그 구성이 간단해지므로써 제작단가 및 고장율이 적어 소비자에게 신뢰성을 가지는 냉동시스템을 제공할 수 있는 효과가 있는 것이다.The present invention as described above has the effect of providing a refrigeration system having a reliable reliability to consumers because the manufacturing cost and failure rate is simpler than the conventional indirect heat exchange method.
