Description

가스엔진 히트펌프{Gas Engine Heat Pump}Gas engine heat pump

본 발명은 가스엔진으로 히트펌프를 구동시키는 장치에 관한 것이다.The present invention relates to an apparatus for driving a heat pump with a gas engine.

히트펌프는 일반적으로 냉매의 순환 사이클을 이용하여 필요한 곳에 열을 공급하거나 열을 흡수하는 사이클을 의미한다. 이러한 히트펌프는 압축기를 구동하여 냉매를 압축하고, 압축된 냉매를 응축기, 팽창밸브 그리고 증발기로 순환시켜 다른 유체와 열교환하는 장치이다. The heat pump generally means a cycle of supplying heat or absorbing heat where necessary using a circulation cycle of the refrigerant. The heat pump is a device that compresses a refrigerant by driving a compressor, and circulates the compressed refrigerant through a condenser, an expansion valve, and an evaporator to exchange heat with other fluids.

가스엔진 히트펌프는 가스엔진을 구동하여 압축기를 구동시키는 장치이다. 엔진과 압축기를 벨트로 연결하고, 압축기를 구동시켜, 히트펌프에 냉매가 순환되도록 한다. A gas engine heat pump is a device that drives a gas engine to drive a compressor. The engine and the compressor are connected by a belt, and the compressor is driven to circulate the refrigerant in the heat pump.

엔진의 구동과정에서 엔진에서 발생하는 열은 냉각수를 이용하여, 냉각시킬 수 있다. 이때 사용되는 냉각수는 히트펌프의 실외열교환기나 방열기를 통해 냉각되어 순환되어, 다시 엔진으로 공급될 수 있다. The heat generated in the engine during the driving process of the engine can be cooled using cooling water. At this time, the cooling water used may be cooled and circulated through an outdoor heat exchanger or radiator of the heat pump, and then supplied to the engine.

실외열교환기가 응축기로 사용될 때에는, 방열기를 통한 냉각수 냉각을 할 수 있다. 다만, 이러한 방열기를 통한 냉각수 냉각은 냉각수의 온도를 크게 떨어뜨리지 못하므로, 이후 순환과정에서의 엔진 냉각이 원활하지 않을 수 있으며, 이 경우, 엔진의 출력이 저하될 수 있는 문제가 발생할 수 있다. When the outdoor heat exchanger is used as a condenser, cooling water cooling through a radiator can be performed. However, since cooling of the cooling water through the radiator does not significantly reduce the temperature of the cooling water, engine cooling in a subsequent circulation process may not be smooth, and in this case, a problem that an engine output may be deteriorated may occur.

또한, 가스엔진 히트펌프에서, 엔진에서 배출되는 가스를 이용하여 엔진으로 유입되는 연료를 압축하는 경우, 엔진으로 공급되는 연료가 고압의 상태로 유입될 수 있으며, 이는 엔진의 과부하 또는 과열을 문제를 발생시킬 수 있어, 별도의 냉각장치를 두어 엔진으로 공급되는 연료를 냉각하여 엔진으로 공급할 수 있다. 이러한, 엔진으로 공급되는 연료를 냉각하기 위해서는, 별도의 열교환장비가 추가되어야 하므로, 재료비가 상승할 수 있는 문제가 있다. In addition, in the gas engine heat pump, when compressing the fuel flowing into the engine using the gas discharged from the engine, the fuel supplied to the engine may flow into a high pressure state, which may cause overload or overheating of the engine. Since it can be generated, a separate cooling device can be provided to cool the fuel supplied to the engine and supply it to the engine. In order to cool the fuel supplied to the engine, a separate heat exchange equipment has to be added, so there is a problem in that the material cost can increase.

본 발명이 해결하고자 하는 과제는 엔진에서 발생하는 열을 적절히 냉각하여 엔진출력을 높일 수 있는 가스엔진 히트펌프를 제공하는 것이다.The problem to be solved by the present invention is to provide a gas engine heat pump capable of increasing engine power by appropriately cooling heat generated by the engine.

본 발명의 또 다른 과제는 별도의 추가적인 장비 없이 엔진으로 공급되는 혼합기의 온도를 냉각할 수 있는 가스엔진 히트펌프를 제공하는 것이다. Another object of the present invention is to provide a gas engine heat pump capable of cooling the temperature of the mixer supplied to the engine without additional equipment.
