Description
본 발명은 냉동싸이클 시스템에 관한 것으로, 보다 상세하게는 증발기에 성애가 발생되었을때 압축기에서 발생되는 고온,고압의 냉매가스를 증발기에 공급하여 제상이 이루어질 수 있도록 한 냉동싸이클 시스템을 제공함에 있다.The present invention relates to a refrigeration cycle system, and more particularly, to provide a refrigeration cycle system in which defrosting is performed by supplying a high-temperature, high-pressure refrigerant gas generated in a compressor to an evaporator when defrost occurs.
냉동싸이클 시스템은 상품의 보관온도를 10℃ 이하로 유지하기 위한 자동판매기나 쇼케이스에 장착되어 지는데, 그와 같은 냉동싸이클 시스템이 도 1에 간략하게 도시되어 있는 바, 이를 간단하게 설명하면 다음과 같다.The refrigeration cycle system is mounted on a vending machine or showcase for maintaining the storage temperature of the product below 10 ℃, such a refrigeration cycle system is briefly shown in Figure 1, briefly described as follows .
도시된 바와 같이, 종래 냉동싸이클 시스템은 냉매를 단열 압축시키는 압축기(1)와, 고온 고압의 기체냉매를 고온 등압의 액체로 만들기 위한 응축기(2)와, 고온 고압의 액냉매를 교축시키기 위한 팽창밸브(3), 저온 등압의 냉매를 증발시키기 위한 증발기(4)가 냉매라인(1)으로 연결되어 냉매가 순환할 수 있도록 되어 있다.As shown, a conventional refrigeration cycle system includes a compressor (1) for adiabatic compression of a refrigerant, a condenser (2) for making a high temperature and high pressure gas refrigerant into a high temperature isostatic liquid, and an expansion for throttling a high temperature and high pressure liquid refrigerant. A valve 3 and an evaporator 4 for evaporating the refrigerant at low temperature isostatic pressure are connected to the refrigerant line 1 so that the refrigerant can circulate.
그리고, 상기 증발기(4)와 응축기(2)의 일측에는 열교환효율을 증대시키기 위하여 공기를 송풍하기 위한 송풍팬(5)(5')이 설치되어 있고, 상기 증발기(4)의 일측에 설치된 송풍팬(5)의 주변에는 증발기(4)에 발생되는 성에를 제거하기 위한 히터(6)가 설치되어 있다.And, one side of the evaporator (4) and the condenser (2) is provided with a blowing fan (5) (5 ') for blowing air in order to increase the heat exchange efficiency, the blower installed on one side of the evaporator (4) In the periphery of the fan 5, a heater 6 for removing frost generated in the evaporator 4 is provided.
상기와 같이 구성되어 있는 종래 냉동싸이클 시스템에서는 압축기(1)에서 냉매를 단열압축하여 응축기(2)로 보내면, 그 과열기체냉매는 응축기(2)에서 고온,등압의 액냉매로 변화된다.In the conventional refrigeration cycle system configured as described above, when the refrigerant is adiabaticly compressed by the compressor 1 and sent to the condenser 2, the superheated gas refrigerant is changed into a liquid refrigerant of high temperature and isostatic pressure in the condenser 2.
그런 다음, 상기와 같이 고온, 등압으로 변화된 액냉매는 팽창밸브(3)으로 보내지는데, 그와 같이 보내진 액냉매는 팽창밸브(3)에서 교축되어 저온 등압상태로 변화된다.Then, the liquid refrigerant changed to high temperature and isostatic pressure as described above is sent to the expansion valve (3), the liquid refrigerant so sent is throttled in the expansion valve (3) to change to a low temperature isostatic state.
그런후, 팽창밸브(3)에서 저온 등압으로 변화된 액냉매는 증발기(4)로 보내지게 되는데, 증발기(4)로 보내진 저온 등압의 액냉매는 증발기(4)에서 증발과정을 거치며 주위의 열을 흡수한 후, 저온의 기체상태로 변화하여 압축기(1)로 다시 보내진다.Then, the liquid refrigerant changed to the low temperature isostatic pressure at the expansion valve 3 is sent to the evaporator 4. The low temperature isostatic liquid refrigerant sent to the evaporator 4 undergoes an evaporation process at the evaporator 4 and heats the surrounding heat. After absorbing, it changes to a low temperature gas state and is sent back to the compressor 1.
그리고, 상기 증발기(4)의 주변에 설치된 송풍팬(5)에서는 증발기(4)에 공기를 송풍하여 열교환이 증대되어지도록 한다.In the blower fan 5 installed around the evaporator 4, air is blown to the evaporator 4 so that heat exchange is increased.
또한, 상기와 같은 냉동싸이클 시스템에서는 압축기(1)가 동작되는 동안 상기와 같은 냉동싸이클이 이루어지는데, 증발기(4)에서는 증발되는 저온의 냉매에 의하여 표면에 습기가 응결이 되고, 그 응결된 습기는 얼음 또는 성에로 상태가 변화되는데, 그와 같은 얼음과 성에는 히터(6)에서 발생되는 열에 의하여 제거되어 진다.In addition, in the above-mentioned refrigeration cycle system, the above-mentioned refrigeration cycle is performed while the compressor 1 is operated. In the evaporator 4, moisture condenses on the surface by a low-temperature refrigerant evaporated, and the condensed moisture Is changed to the state of ice or frost, such ice and frost is removed by the heat generated from the heater (6).
그러나, 상기와 같은 종래 냉동싸이클 시스템에서는 증발기(4)의 표면에 응결되는 얼음과 성에를 제거하기 위해서는 압축기(1)의 동작과 무관하게 히터(6)와 송풍팬(5)을 가동하는데, 그와 같이 제상으로 위해 가동되는 히터(6)와 송풍팬(5)에 의하여 고내온도가 상승되므로, 제상이 완료된 후에는 고내온도를 낮추기 위하여 다시 압축기(1)를 동작시켜야 하므로 그로인한 기기의 운전효율저하를 초래하는문제점을 가지고 있었다.However, in the conventional refrigeration cycle system as described above, in order to remove ice and frost condensed on the surface of the evaporator 4, the heater 6 and the blower fan 5 are operated regardless of the operation of the compressor 1. Since the internal temperature is raised by the heater 6 and the blower fan 5 which are operated for defrosting, the compressor 1 needs to be operated again to lower the internal temperature after the completion of the defrosting. There was a problem that caused the degradation.
상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 히터를 배제하고, 압축기의 동작에 의하여 증발기의 제상이 이루어지도록 하여 고내의 온도변화를 최소화하고, 기기의 운전효율을 증대시키도록 하는데 적합한 냉동싸이클 시스템을 제공함에 있다.The object of the present invention devised in view of the above problems is to remove the heater, the defrost of the evaporator by the operation of the compressor to minimize the temperature change in the refrigerator, suitable for increasing the operating efficiency of the device In providing a cycle system.

상기와 같이 구성되어 있는 본 발명 냉동싸이클 시스템에서는 냉매가압축기(101)에서 단열압축되어 고온고압 상태로 제1 냉매라인(103)을 통하여 응축기(102)로 공급되고, 응축기(102)로 공급된 고온고압의 기체는 등온등압의 액체상태로 변화되며, 그와 같이 액화된 냉매는 제2 냉매라인(105)를 통하여 팽창밸브(104)로 보내지는데, 팽창밸브(104)에서는 등온등압의 고온 액냉매를 교축시켜서 저압등온상태로 변화시키며, 그와 같이 변화된 냉매는 제3 냉매라인(107)을 통하여 증발기(106)로 보내져서 저온등압의 냉매를 증발시킨 후, 제4 냉매라인(108)을 통하여 압축기(101)로 회수되는 냉동싸이클이 이루어진다.In the present invention the refrigeration cycle system configured as described above is adiabatic compression in the refrigerant compressor 101 is supplied to the condenser 102 through the first refrigerant line 103 in a high temperature and high pressure state, and is supplied to the condenser 102 The gas at high temperature and high pressure is changed into a liquid state of isothermal isostatic pressure, and the liquefied refrigerant is sent to the expansion valve 104 through the second refrigerant line 105, and the expansion valve 104 is of isothermal isostatic pressure. The high temperature liquid refrigerant is throttled to change to a low pressure isothermal state, and the changed refrigerant is sent to the evaporator 106 through the third refrigerant line 107 to evaporate the low temperature isothermal refrigerant, and then the fourth refrigerant line ( The refrigeration cycle is recovered to the compressor 101 through 108.
상기와 같이 냉동싸이클 동작은 일정온도 즉, 냉동 또는 냉장 목적으로 설정온도에 도달할때까지 반복적으로 행해지며, 그와 같은 동작이 반복됨에 따라 증발기(106)의 표면에는 주위의 습기 또는 공기에 의하여 결빙이 발생된다.As described above, the refrigeration cycle operation is repeatedly performed until a predetermined temperature is reached, i.e., a set temperature for refrigeration or refrigeration purposes, and as such an operation is repeated, the surface of the evaporator 106 is replaced by ambient moisture or air. Freezing occurs.
그리고, 그와 같이 증발기(106)에 결빙이 발생되면 제상동작이 이루어지는데, 그 동작을 상세히 설명하면, 먼저 제1 삼방밸브(111)에서 제1 냉매라인(103)쪽이 닫히고 제1 역류라인(121)쪽이 열림과 동시에 솔레노이드 밸브(127)가 열려서 압축기(101)에서 단열압축된 고온고압의 과열증기 냉매가 증발기(106)로 보내지고, 그와 같이 증발기(106)에 공급된 고온고압의 과열증기 냉매는 증발기(106)의 내부를 흐르며 표면에 결빙된 성애를 제거하게 된다.When defrost occurs in the evaporator 106 as described above, a defrosting operation is performed. When the operation is described in detail, first, the first refrigerant line 103 is closed in the first three-way valve 111 and the first backflow line is performed. At the same time as the (121) side is opened, the solenoid valve 127 is opened so that the high temperature and high pressure superheated steam refrigerant adiabaticly compressed by the compressor 101 is sent to the evaporator 106, and the high temperature and high pressure supplied to the evaporator 106 as such. The superheated steam refrigerant flows inside the evaporator 106 to remove the frost formed on the surface.
상기와 같이 증발기(106)의 내부를 통과하는 냉매는 성애로부터 열원을 흡수하며 고온등압의 액냉매로 변화되고, 이와 같이 변화된 액냉매는 제2 역류라인(123)을 통하여 팽창밸브(104)에 도달되는데, 그와 같이 팽창밸브(104)에 공급된 냉매는 교축되어 저온등압상태로 변화된다.As described above, the refrigerant passing through the inside of the evaporator 106 absorbs the heat source from the frost and is changed into a liquid refrigerant having a high temperature isostatic pressure, and the changed liquid refrigerant is expanded through the second backflow line 123.

Next, it is recovered back to the compressor 101 through the fourth backflow line 126 and the second three-way valve 112.
상기와 같은 제상동작을 일정시간 실시하여 증발기에 발생된 성애를 제거한 후에는 다시 냉동싸이클이 동작되어 진다.After the defrosting operation is performed for a predetermined time to remove the defrost generated in the evaporator, the refrigeration cycle is operated again.
이상에서 상세히 설명한 바와 같이, 본 발명의 냉동싸이클 시스템은 압축기에서 압축된 냉매가 응축기, 메인 팽창밸브, 증발기를 거쳐서 압축기로 다시 회수되며 냉동싸이클이 진행되고, 증발기를 제상할때는 압축기에서 압축된 고온고압의 증기상태인 냉매를 증발기, 보조 팽창밸브, 응축기를 거쳐서 압축기로 회수되도록 구성하여, 압축기에서 발생되는 고온고압의 냉매가스를 이용하여 증발기의 제상이 이루어질 수 있도록 함으로써, 넓은 면적을 빠르게 제상할 수 있다.As described in detail above, in the refrigeration cycle system of the present invention, the refrigerant compressed in the compressor is recovered back to the compressor through the condenser, the main expansion valve, and the evaporator, and the refrigeration cycle is in progress. It is configured to recover the refrigerant in the vapor state to the compressor through the evaporator, the auxiliary expansion valve, and the condenser, so that the defrost of the evaporator can be defrosted by using the refrigerant gas of the high temperature and high pressure generated from the compressor, thereby rapidly defrosting a large area. have.
또한, 종래의 히터를 사용하는 경우에는 제상후 고내를 일정온도로 유지시키기 위하여 일정시간동안 압축기를 동작시켰으나, 본 발명에서는 동작시키지 않아도 되므로 절전효과가 향상되는 효과가 있다.In addition, in the case of using a conventional heater, the compressor was operated for a predetermined time in order to maintain the inside of the refrigerator at a constant temperature after defrosting, but the present invention does not need to operate, so that the power saving effect is improved.
