Description

냉매조절 및 제상기능을 갖는 공기조화기{an air conditioner with defrosting and controling coolant}An air conditioner with defrosting and controling coolant

본 발명은 계절에 따른 냉매의 체적변화에 대응하여 싸이클에 적정량의 냉매를 지속적으로 공급토록 하면서 싸이클을 차단한 후 제상기능만을 효율적으로 활용토록 하는 냉매조절 및 제상기능을 갖는 공기조화기에 관한 것이다.The present invention relates to an air conditioner having a refrigerant control and a defrost function to efficiently utilize only a defrost function after blocking a cycle while continuously supplying an appropriate amount of refrigerant to a cycle in response to a volume change of the refrigerant according to a season.

일반적으로 히트펌프는, 실내기, 팽창유니트, 실외기, 압축기, 및 사방밸브를 포함하는 구성으로 동절기 난방 회로로 작동하는 경우 실외기로 유입되는 공기의 습도가 높고 온도가 낮게 되면 실외기에 착상이 발생하여 열교환기의 기능을 상실하게 된다. In general, a heat pump includes an indoor unit, an expansion unit, an outdoor unit, a compressor, and a four-way valve, and when operating in a winter heating circuit, when the humidity of the air flowing into the outdoor unit is high and the temperature is low, an frost is generated in the outdoor unit. The function of the machine will be lost.

이러한 경우 실외기의 제상이 요구되며 히트펌프를 냉방회로로 가동하여 실외기를 응축기로, 실내기를 증발기로 운전함으로써 고온, 고압의 액체냉매가 실외기로 흘러가도록 하여 실외기에 부착된 서리를 제거하는 제상 방법을 사용한다. In this case, defrosting of the outdoor unit is required, and a defrosting method of removing the frost attached to the outdoor unit by removing the frost attached to the outdoor unit by operating the heat pump as a cooling circuit and operating the outdoor unit as a condenser and the indoor unit as an evaporator to flow high-temperature and high-pressure liquid refrigerant to the outdoor unit. use.

그러나, 이러한 경우 실내기는 증발기로 작동하기 때문에 더 이상의 실내 난방이 불가능해 지는 문제점이 있는 것이다.However, in this case, since the indoor unit operates as an evaporator, there is a problem that further indoor heating is impossible.

이와같은 문제점을 개선하기 위하여 특허 제712196호에 히트펌프의 기술이 제시되고 있으며 그 구성은 도1에서와 같이, 히트펌프가 난방 회로로 작동하는 경우 압축기(200)를 나온 고온, 고압의 냉매는 사방밸브(210)와 제어밸브(250)를 통해 응축기로 동작하는 실내기 코일(320)로 유입되고 실내기 송풍기(300)의 동작에 의해 실내 난방이 이루어진다.In order to improve such a problem, the technique of the heat pump is proposed in Patent No. 712196. The configuration of the high temperature and high pressure refrigerant exiting the compressor 200 when the heat pump operates as a heating circuit is shown in FIG. Through the four-way valve 210 and the control valve 250 is introduced into the indoor unit coil 320 to operate as a condenser and the indoor heating is performed by the operation of the indoor unit blower (300).

그리고, 실내기 코일(320)을 통과한 냉매는 난방 팽창밸브(230)에서 감압된 후 증발기로 작동하는 실외기 주코일(220)로 유입되고 실외기 송풍기(270)의 동작에 의해 냉매 증발이 원활하게 수행되며, 실외기 주코일(220)을 통과한 냉매는 사방밸브(210)와 어큐뮬레이터(280)를 거쳐 다시 압축기(200)로 유입되는 과정을 거쳐 난방 운전이 완성된다.In addition, the refrigerant passing through the indoor unit coil 320 is reduced in the heating expansion valve 230 and then flows into the outdoor unit main coil 220 which operates as an evaporator, and the refrigerant evaporates smoothly by the operation of the outdoor unit blower 270. The refrigerant passing through the outdoor unit main coil 220 passes through the four-way valve 210 and the accumulator 280 and flows back into the compressor 200 to complete the heating operation.

더하여, 사방밸브(210)의 전환에 의해 압축기(200)를 나온 고온, 고압의 냉매 일부는 실외기 주코일(220)로 유입되어 실외기 주코일(220) 표면에 착상된 서리를 녹이고, 동시에 압축기(200)를 나온 고온 고압 냉매의 일부는 실내기 코일(320)로 유입되어 제상과 실내 난방을 동시에 수행하며, 실외기 주코일(220)을 통과한 냉매와 실내기 코일(320)을 통과한 냉매는 난방 팽창밸브(235) 전단에서 합쳐진 후 난방 팽창밸브(235)와 제어밸브(250)를 거쳐 증발기 역할을 하는 실외기 보조코일(260)로 유입되고, 실외기 보조코일(260)에서 증발된 냉매는 다시 제어밸브(250)와 사방밸브(210), 어큐뮬레이터(280)를 거쳐 다기 압축기(200)로 유입되며 제상 및 난방 운전이 완성되는 것이다.In addition, a part of the high-temperature and high-pressure refrigerant exiting the compressor 200 by the switching of the four-way valve 210 flows into the outdoor unit main coil 220 to melt frost formed on the surface of the outdoor unit main coil 220, and at the same time, the compressor ( Some of the high temperature and high pressure refrigerant from 200 flows into the indoor unit coil 320 to perform defrost and indoor heating at the same time, and the refrigerant passing through the outdoor unit main coil 220 and the refrigerant passing through the indoor unit coil 320 are expanded by heating. After being combined at the front end of the valve 235, the heating expansion valve 235 and the control valve 250 are introduced into the outdoor unit auxiliary coil 260 serving as an evaporator, and the refrigerant evaporated from the outdoor unit auxiliary coil 260 is again a control valve. Through the 250 and the four-way valve 210, the accumulator 280 is introduced into the multi-compressor 200 is completed defrosting and heating operation.

그러나, 상기와 같은 히트펌프는, 계절에 따른 냉매의 부피변화에 용이하게 대처하지 못하여 균일한 압축효율의 유지가 힘들게 되고, 제상과 난방이 동시에 이루어져 원하는 제상 또는 난방효율을 가져올 수 없게 되는 단점이 있는 것이다.However, the heat pump as described above has a disadvantage in that it is difficult to easily cope with the change in volume of the refrigerant according to the season, so that it is difficult to maintain a uniform compression efficiency, and that defrosting and heating are performed at the same time, thereby failing to bring about desired defrosting or heating efficiency.
