Description
본 발명은 히트 펌프 시스템에 관한 것이다.The present invention relates to a heat pump system.
주지하는 바와 같이 히트 펌프 시스템은 압축기, 4방밸브, 실내 열교환기, 팽창밸브, 실외 열교환기 및 상기 4방밸브를 도관으로 순서대로 연결하고, 상기 4방밸브와 압축기를 흡입도관으로 연결하여서 가열운전시에는 4방밸브를 냉매가 실내 열교환기 측으로 흐르도록 조작하여 압축기에서 압축된 고온·고압의 냉매가스를 응축기로 작용하는 실내 열교환기에 흐르도록 하여 그 응축열을 유체와 열교환시킴으로서 온수를 생성하거나 실내공기를 가열하여 난방 또는 피건조물의 건조기능을 수행하고, 실내 열교환기에서 응축된 고온·고압의 냉매액을 팽창밸브에서 팽창시킨 후 증발기로 작용하는 실외 열교환기에서 외기를 열원으로 하여 증발시켜 저온·저압의 가스상태가 되게 한 후 압축기에 흡입되는 사이클을 반복하는 것이다. 그리고 냉각운전시에는 4방밸브를 냉매가 실외 열교환기 측으로 흐르도록 조작하여 압축기에서 압축된 고온·고압의 냉매가스를 응축기로 작용하는 실외 열교환기에서 응축시키고, 실외 열교환기에서 응축된 고온·고압의 냉매액을 팽창밸브에서 팽창시킨 후 증발기로 작용하는 실내 열교환기에서 유체와 열교환시킴으로서 냉수를 생성하거나, 실내공기를 냉각하여 냉방 또는 피냉장물의 냉장기능을 수행하며, 실내 열교환기에서 증발된 저온·저압의 냉매가스가 압축기에 흡입되는 사이클을 반복하는 것이다.As is known, the heat pump system is connected to the compressor, four-way valve, indoor heat exchanger, expansion valve, outdoor heat exchanger and the four-way valve in order to the conduit, and the four-way valve and the compressor by the suction conduit to heat During operation, the 4-way valve is operated so that the refrigerant flows to the indoor heat exchanger, so that the high-temperature and high-pressure refrigerant gas compressed by the compressor flows to the indoor heat exchanger acting as a condenser, and heats the condensation heat with the fluid to generate hot water. The air is heated to perform heating or drying of the dried product, and the high-temperature and high-pressure refrigerant liquid condensed in the indoor heat exchanger is expanded in the expansion valve, and the outdoor heat exchanger acts as an evaporator to evaporate the outdoor air as a heat source. • The cycle of suction into the compressor is repeated after bringing it to a low pressure gas state. During the cooling operation, the 4-way valve is operated so that the refrigerant flows to the outdoor heat exchanger to condense the high-temperature and high-pressure refrigerant gas compressed by the compressor in the outdoor heat exchanger acting as a condenser, and the high-temperature and high pressure condensed in the outdoor heat exchanger. After cooling the refrigerant liquid in the expansion valve and heat exchange with the fluid in the indoor heat exchanger acting as an evaporator to generate cold water, or to cool the indoor air to perform the cooling or cooling of the object to be cooled, and the low temperature evaporated in the indoor heat exchanger The cycle of inhaling low pressure refrigerant gas into the compressor is repeated.
또한 상기한 히트 펌프 시스템은 부속장치로서, 응축기로 작용하는 실내 또는 실외 열교환기의 출구측에 수액기를, 증발기로 작용하는 실내 또는 실외 열교환기의 출구측에 액분리기를 설치하는 바, 상기 수액기 및 액분리기를 일체화하여 구조를 단순화하고 응축기 출구에서 냉매액을 과냉하며 증발기 출구에서 냉매가스의 증발 효율을 증대한 냉난방 공기 조화기가 특허 제 136759 호 공보에 개시되어 있는 바, 상기 냉난방 공기 조화기는 압축기, 4방밸브, 실외 열교환기, 수액기, 실내 열교환기, 4방밸브를 도관으로 차례로 연결하고, 상기 4방밸브와 압축기 사이에 상기 수액기에 내장되는 액분리기를 연결하여 상기 액분리기 내부에 전열핀과 망으로 형성된 증발수단을 설치하며, 상기 수액기 내부에 냉매 흐름 전환밸브를 설치하여 냉방 또는 난방시에 상기 냉매 흐름 전환밸브를 경유하여 수액기내로 유입된 냉매를 감압장치로 유출시키는 냉매 출구관으로 구비한 것이다.In addition, the heat pump system is an accessory device, which is provided with a receiver on the outlet side of the indoor or outdoor heat exchanger serving as a condenser, and a liquid separator on the outlet side of the indoor or outdoor heat exchanger serving as an evaporator. And a cooling and cooling air conditioner that integrates a liquid separator to simplify the structure, supercool the refrigerant liquid at the outlet of the condenser, and increase the evaporation efficiency of the refrigerant gas at the outlet of the evaporator. And a 4-way valve, an outdoor heat exchanger, a receiver, an indoor heat exchanger, and a 4-way valve in sequence with a conduit, and connect the liquid separator embedded in the receiver between the 4-way valve and the compressor to heat the inside of the separator. When the cooling or heating by installing the evaporation means formed by the pin and the net, and the refrigerant flow switching valve inside the receiver By way of the refrigerant flow switching valve it is provided with a refrigerant outlet pipe to the outlet of the refrigerant flowing into the receiver on board a pressure reducing device.
그러나 상기한 히트 펌프 시스템은 실내 열교환기의 응축열 또는 증발열만을 이용하고 실외 열교환기의 증발열 또는 응축열은 폐기하면서 유체의 가열 또는 냉각 기능만을 수행함으로 열원의 효율적인 이용이 불가능하고, 또한 유체의 가열 및 냉각기능을 동시에 수행하여야 할 경우에는 2 대의 히트 펌프 시스템을 설치하여야 함으로 구조가 복잡하여지고 설치면적을 많이 차지하며 비용이 과다 소요되는 문제점이 있는 것이다. However, the heat pump system uses only the heat of condensation or the heat of evaporation of the indoor heat exchanger and performs only the heating or cooling function of the fluid while discarding the heat of evaporation or the condensation of the outdoor heat exchanger. If the functions must be performed at the same time, two heat pump systems must be installed, resulting in a complicated structure, a large installation area, and an excessive cost.
그리고, 상기한 냉·난방 공기 조화기는 상기한 히트 펌프 시스템과 같이 유체의 가열 또는 냉각 기능만을 수행함으로서 열원의 효율적인 이용이 불가능한 등의 문제점이 있고, 또한 수액기내에 냉매 흐름 전환밸브를 설치하고 냉매 출구관을 별도로 설치한 것임으로 구조가 복잡하고, 냉매 흐름 전환밸브의 고장시 수액기겸 액분리기 전체를 폐기하여야 할 뿐 아니라 증발수단이 액분리기에 내장되어 있음으로 냉매액의 과냉 및 냉매가스의 증발 효율이 저조하기 때문에 효율증대(성적계수의 증대)가 저조한 문제점등이 있는 것이다. In addition, the cooling / heating air conditioner has a problem such that the efficient use of a heat source is not possible by performing only a heating or cooling function of the fluid as in the heat pump system. Since the outlet pipe is installed separately, the structure is complicated. In case of failure of the refrigerant flow switching valve, the entire receiver and the liquid separator must be discarded. Also, since the evaporation means is built in the liquid separator, the refrigerant liquid is supercooled and the refrigerant gas is evaporated. Since the efficiency is low, there is a problem that the efficiency increase (increase of the coefficient of performance) is low.
본 발명은 상기한 문제점을 감안하여, 1대의 시스템에서 가열기능 및 냉각기능을 동시에 발휘하여 열원을 효율적으로 이용하고 구조를 단순화함과 동시에 설치면적을 작게 차지하며, 성적계수를 획기적으로 증대한 히트 펌프 시스템을 제공하는 것을 목적으로 한다. In view of the above problems, the present invention simultaneously utilizes a heating function and a cooling function in one system to efficiently use a heat source, simplify the structure, occupy a small installation area, and dramatically increase the coefficient of performance. It is an object to provide a pump system.

The four-way valve 3 operates the refrigerant to flow in a solid arrow line, and when the compressor 2 is driven, the high-temperature / high-pressure refrigerant gas compressed by the compressor 2 acts as a condenser via the conduit 8b. While condensing in the heat exchanger (4) heats the condensation heat with the water or air as a fluid to generate hot water, or to heat the indoor air to perform the heating or drying of the dry matter, the high temperature condensed in the indoor heat exchanger (4) High pressure refrigerant liquid is temporarily stored in the receiver 11 via the check valve 17 of the conduit 8c and then expanded in the expansion valve 6 and then flows into the second heat exchanger 7 which acts as an evaporator. Heat exchange with the fluid to produce cold water by the heat of evaporation or to cool the indoor air to perform the cooling or cooling of the object to be cooled, and the low-temperature low-pressure refrigerant gas evaporated in the second heat exchanger (7) is a conduit (8d) , 4-way valve (3), suction conduit The heating and cooling functions are simultaneously performed in one system while repeating the cycle of being sucked into the compressor (2) via the liquid separator (12) installed in (9).
