본 고안은 히트펌프 시스템에 사용되는 히트펌프용 액분리기에 관한 것으로, 더욱 상세하게는 액분리기의 외둘레 일측 또는 양측에 별도로 설치된 증발기장치의 고온증발가스를 공급하는 제1고온가스관을 연결설치하고, 상기 액분리기 상부에 설 치된 흡입관에 별도로 설치된 증발기장치의 고온증발가스를 공급하는 제2고온가스관을 연결설치하여 외기온도가 낮아 히트펌프 시스템의 효율이 떨어질 경우 별도로 구성된 증발기장치에서 고온냉매가스를 제1,2 고온가스관을 통해 액분리기에 공급함으로서, 낮은 외기온도에 의한 냉매의 증발량저하를 방지함과 동시에 액상태의 냉매를 기체상태의 냉매로 고온으로 증발시켜 히트펌프 시스템을 정상운행 가능하게 함과 동시에 효율을 증대하는 효과가 있는 히트펌프용 액분리기에 관한 것이다.The present invention relates to a liquid separator for a heat pump used in a heat pump system, and more particularly, by connecting and installing a first high temperature gas pipe for supplying a high temperature evaporation gas of an evaporator device installed on one side or both sides of a liquid separator. In order to reduce the efficiency of the heat pump system by connecting the second high temperature gas pipe for supplying the high temperature evaporation gas of the evaporator device separately installed in the suction pipe installed on the liquid separator, the high temperature refrigerant gas is separated from the separately configured evaporator device. By supplying to the liquid separator through the first and second hot gas pipes, the evaporation amount of the refrigerant is prevented from being lowered due to the low outside temperature and the liquid refrigerant is evaporated to a high temperature with the gaseous refrigerant to enable the heat pump system to operate normally. In addition, the present invention relates to a liquid separator for a heat pump having an effect of increasing efficiency.

일반적으로 히트펌프는 프레온가스 등을 냉매로 이용하여 온도가 낮은 곳의 열을 높은 곳으로 끌어올려 냉·난방기에 사용되는 것이다.In general, the heat pump is used for cooling and heating by using a freon gas as a refrigerant to raise the heat of the low temperature to a high place.

이때, 사용되는 액분리기는 증발기와 압축기 사이의 흡입배관에 설치되어 흡입가스 중 냉매액이 혼합되었을 때 이것을 분리하여 가스만 압축기로 공급시켜 액압축(증발기에서 압축기로 유입되는 냉매 중에서 액냉매가 증발하지 못하고 액체로 유입되는 현상)을 방지하여 압축기를 보호하는 역할을 하는 것이다.At this time, the liquid separator used is installed in the suction pipe between the evaporator and the compressor, and when the refrigerant liquid in the suction gas is mixed, it is separated and supplied only to the compressor to supply liquid gas (liquid refrigerant evaporates from the refrigerant flowing into the compressor from the evaporator). To prevent the flow of liquid into the liquid) to protect the compressor.

이러한, 종래의 액분리기는 도1에 도시된 바와 같이 원통형상의 액분리기(100) 상부를 관통하여 설치되어 증발기에서 공급된 냉매(가스와 액체의 혼합)가 유입되는 "I"자 형상의 흡입관(110)과 액분리기에서 가스만 분리된 냉매를 유출하는 "U"자 형상의 배출관(120)이 형성된다.Such a conventional liquid separator is installed through the upper portion of the cylindrical liquid separator 100, as shown in FIG. 1, and the "I" shaped suction pipe into which the refrigerant (mixing of gas and liquid) supplied from the evaporator flows in ( 110) and a discharge pipe 120 having a “U” shape for flowing out the refrigerant separated only by the gas from the liquid separator is formed.

그러나, 이와 같은 종래 액분리기는 외기온도가 낮을 경우 냉매의 증발량이 감소함으로서, 액분리기에서 압축기로 공급되는 냉매가스의 공급량이 감소하여 히트펌프 시스템의 효율의 저하와 함께 정상적인 냉난방이 어려운 문제점이 있었다.However, such a conventional liquid separator has a problem that when the ambient temperature is low, the amount of refrigerant evaporated decreases, and thus the amount of refrigerant gas supplied from the liquid separator to the compressor decreases, thereby degrading the efficiency of the heat pump system and making it difficult to normally heat and cool. .

본 고안은 상기 언급한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 히트펌프 시스템에 사용되는 액분리기를 외기온도에 관계없이 정상운행되도록 하여 언제나 정상운행이 가능하도록 함과 동시에 히트펌프 시스템의 효율을 증대하는 히트펌프용 액분리기를 제공하는데 있다.The present invention is to solve the above-mentioned problems, an object of the present invention is to ensure that the liquid separator used in the heat pump system to operate normally regardless of the outside temperature at all times to enable normal operation at the same time the efficiency of the heat pump system It is to provide a liquid separator for a heat pump to increase the.

이를 이루기 위한 구체적인 기술구성은,Specific technical configuration to achieve this,

상부에 증발기에서 공급된 냉매를 공급하는 흡입관과 압축기로 냉매를 공급하는 공급관이 설치된 히트펌프 시스템에 사용되는 액분리기에 있어서, 상기 액분리기 외둘레 일측 또는 양측에, 별도로 설치된 증발기장치에서 공급된 고온가스를 공급하는 제1고온가스관을 연결설치하여 이루어진다.A liquid separator used in a heat pump system having a suction pipe for supplying a refrigerant supplied from an evaporator and a supply pipe for supplying a refrigerant to a compressor at an upper portion thereof, wherein a high temperature is supplied from an evaporator device separately installed on one or both sides of the liquid separator. It is made by connecting and installing a first hot gas pipe for supplying gas.

또한, 상기 액분리기의 흡입관에, 별도로 설치된 증발기장치에서 공급된 고온가스를 공급하는 제2고온가스관을 더 연결설치하여 이루어진다.In addition, the suction pipe of the liquid separator, it is made by connecting the second high temperature gas pipe for supplying the hot gas supplied from the separately installed evaporator device.

다음은 첨부된 도면을 참조하여 본 고안을 보다 상세히 설명하면, Next, the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 고안에 따른 히트펌프용 액분리기를 도시한 요부측단면도이고, 도 3은 본 고안에 따른 히트펌프용 액분리기를 적용한 히트펌프 시스템의 실시 예를 도시한 개략도이다.2 is a sectional view showing a main portion of a heat pump liquid separator according to the present invention, and FIG. 3 is a schematic diagram showing an embodiment of a heat pump system to which the liquid separator for heat pump according to the present invention is applied.

도 2와 도 3에 도시된 바와 같이, 본 고안은 히트펌프 시스템에 사용되는 액분리기(1)에 관한 것으로, 상부에 증발기(7)에서 공급된 냉매를 공급하는 흡입관(11)과 압축기(4)로 냉매를 공급하는 공급관(12)이 설치된 액분리기(1)에 히트펌프 시스템과 별도로 외부에 설치된 증발기장치(8)에서 공급되는 고온가스를 액분리 기의 외둘레 일측 또는 양측에 제1고온가스관(2)을 연결설치하여 액분리기(1)에 공급하는 것이다.As shown in Figures 2 and 3, the present invention relates to a liquid separator 1 used in the heat pump system, the suction pipe 11 and the compressor (4) for supplying the refrigerant supplied from the evaporator (7) at the top The high temperature gas supplied from the evaporator device 8 installed outside the heat pump system to the liquid separator 1 having the supply pipe 12 for supplying the refrigerant to the first separator at one or both sides of the outer circumference of the liquid separator. The gas pipe 2 is connected and installed to supply the liquid separator 1.

즉, 외기온도가 낮을 경우 증발기(7)에서 공급되는 냉매의 온도가 극히 낮거나 완전히 기화되지 못하여 액분리기(1)의 온도가 저하됨에 따라 증발기(7)에서 공급되는 냉매가 액분리기(1)에 저장된 액상태의 냉매를 통과하여 압축기(4)로 기체상태의 냉매를 정상적으로 공급하지 못할 뿐만 아니라, 액분리기(1)에 저장된 냉매의 증발량이 떨어져 히트펌프 시스템의 운행이 정지될 수 있기 때문에 이를 방지하기 위해, 외기온도가 낮을 경우 액분리기(1)에 저장된 액상태의 냉매를 외부에 별도로 설치된 증발기장치(8)에서 공급되는 고온가스를 제1고온가스관(2)을 통해 액분리기(1)에 공급함으로서, 액상태의 냉매가 고온증발하여 기체상태의 냉매로 기화되어 냉매의 증발량을 증대시켜 압축기(4)에 공급하여 외부온도에 상관없이 히트펌프 시스템의 정상운행과 함께 운전효율을 증대시키는 것이다.That is, when the outside temperature is low, the refrigerant supplied from the evaporator 7 is extremely low or not completely vaporized, and thus the temperature of the liquid separator 1 is lowered, so that the refrigerant supplied from the evaporator 7 is separated from the liquid separator 1. Not only does it not normally supply gaseous refrigerant to the compressor 4 by passing through the refrigerant in the liquid state stored therein, but also because the evaporation amount of the refrigerant stored in the liquid separator 1 falls, the operation of the heat pump system may be stopped. In order to prevent, when the outside air temperature is low, the high-temperature gas supplied from the evaporator device 8 separately installed in the liquid state refrigerant stored in the liquid separator 1 to the outside through the first high temperature gas pipe (2) (1) By supplying to the refrigerant, the liquid refrigerant evaporates at a high temperature, vaporizes into a gaseous refrigerant, increases the amount of evaporation of the refrigerant, and supplies it to the compressor (4) so that the normal operation of the heat pump system Together, it will increase the driving efficiency.

또한, 상기 히트펌프 시스템의 액분리기(1)의 상단에 설치된 흡입관(11)에 제 2고온가스관(3)을 더 연결설치하고 외부에 별도로 설치된 증발기장치(8)에서 공급된 고온가스를 공급하여 증발기(7)에서 유입되는 냉매에 고온가스를 혼합함으로서, 일부의 고온가스는 액분리기(1)에 저장된 냉매를 기화시키고 액분리기(1)를 통과한 일부 가스는 빠르게 배출관(12)을 통해 압축기(4)로 공급하게 되어 액분리기(1)는 냉매의 증발량을 증대시킴과 동시에 히트펌프 시스템의 운전에 필요한 냉매(기체)를 빠르게 압축기(4)에 공급할 수 있는 장점이 있는 것이다.In addition, the second hot gas pipe (3) is further connected to the suction pipe (11) installed on the top of the liquid separator (1) of the heat pump system, and the hot gas supplied from the evaporator device (8) separately installed outside to supply By mixing hot gas with the refrigerant flowing from the evaporator 7, some of the hot gas vaporizes the refrigerant stored in the liquid separator 1, and some of the gas passing through the liquid separator 1 is quickly passed through the discharge pipe 12. The liquid separator 1 has an advantage of increasing the evaporation amount of the refrigerant and at the same time supplying the refrigerant (gas) necessary for the operation of the heat pump system to the compressor 4.

또한, 위에서 언급한 제1고온가스관(2)과 제2고온가스관(3)을 액분리기(1)에 동시에 설치할 경우 외부기온의 낮아 발생 되는 문제점을 빠르게 해결할 수 있을 뿐만 아니라 보다 효율적으로 히트펌프 시스템의 운행이 가능할 것이다.In addition, when the above-mentioned first high temperature gas pipe (2) and the second high temperature gas pipe (3) at the same time installed in the liquid separator (1) can not only solve the problem caused by low external temperature quickly, but also heat pump system more efficiently Will be available.

도 3에 도시된 것은 본 고안에 따른 히트펌프용 액분리기의 일 실시 예를 도시한 것으로 그 시스템을 간략히 설명하면, 일반적으로 사용되는 히트펌프 시스템과 같이 프레온가스와 같은 가스를 냉매로 이용해 온도가 낮은 곳의 열을 높은 곳으로 끌어올리는 냉·난방기기에 사용되는 것으로, 히트펌프 시스템의 냉·난방은 냉매를 이용해 온도가 낮은 곳에 있는 열을 높은 곳으로 끌어올려 한쪽은 차갑게 하고 다른 쪽은 뜨겁게 만드는 것이 기본 원리이고, 냉매는 도면에 도시된 바와 같이 압축기(4)를 통해 의해 압축되고, 압축에 따라 고온고압으로 된 냉매가스가 열교환기(5)에서 응축, 액화된다. 액화된 냉매는 수액기(6)에 액냉매로 저장되었다가 증발기(7)에서 증발가스화되어 다시 액분리기(1)에 공급되는 것이다. 또한 액분리기(1)에서 증발된 냉매는 다시 압축기(4)에 공급되어 같은 작용을 반복하게 되는 것이다.3 illustrates an embodiment of a liquid separator for a heat pump according to the present invention. Briefly describing the system, the temperature is increased by using a gas such as a freon gas as a refrigerant, such as a heat pump system that is generally used. It is used for cooling and heating equipment that raises heat from low place to high place. The heat and cooling system of heat pump system uses refrigerant to raise heat at low temperature to high place to cool one side and hot other side. The basic principle is to make, and the refrigerant is compressed by the compressor 4 as shown in the drawing, and the refrigerant gas, which has become hot and high pressure in accordance with the compression, is condensed and liquefied in the heat exchanger 5. The liquefied refrigerant is stored as a liquid refrigerant in the receiver 6, and then evaporated in the evaporator 7 and supplied to the liquid separator 1 again. In addition, the refrigerant evaporated in the liquid separator 1 is supplied to the compressor 4 again to repeat the same action.

이때, 열교환기(5)에서 응축 액화된 냉매는 수액기(6)를 통해 저장되고 열교환기(5)를 통해 열교환된 물은 온수탱크 등의 저장시설에 의해 저장되어 난방 또는 온수로 사용되는 것이다.At this time, the refrigerant condensed and liquefied in the heat exchanger 5 is stored through the receiver 6 and the heat exchanged through the heat exchanger 5 is stored by a storage facility such as a hot water tank to be used as heating or hot water. .

또한, 상기 액분리기(1)는 증발기(7)에서 증발된 냉매가 완전 기화되지 못할 경우 발생 되는 문제점을 해소하기 위해 증발기(7)에서 증발된 냉매 중 기화된 기체상태의 냉매만 다시 압축기(4)로 공급하기 위한 것이다.In addition, the liquid separator 1 is a gaseous refrigerant of the vaporized refrigerant from the evaporator 7 again to solve the problem caused when the refrigerant evaporated in the evaporator 7 is not completely vaporized again compressor 4 ) To supply.

이러한, 액분리기(1)는 냉매를 가스로 사용하는 가스히트펌프에 적용하는 것 이 바람직할 것이다.Such a liquid separator 1 may be preferably applied to a gas heat pump using a refrigerant as a gas.

이상과 같이, 본 고안은 냉난방기에 사용되는 히트펌프 시스템에 사용되는 액분리기에 별도의 증발기장치에서 고온가스를 액분리기와 흡입관에 공급함으로서, 외기온도가 낮을 경우 발생 되는 냉매의 증발량 감소를 방지함과 동시에 본체 내부의 액상태의 냉매를 기체상태의 냉매로 고온증발시켜 히트펌프 시스템을 정상운행 가능하게 할 뿐만 아니라, 히트펌프 시스템의 효율을 증대하는 효과가 있다.As described above, the present invention by supplying the hot gas to the liquid separator and the suction pipe in a separate evaporator device to the liquid separator used in the heat pump system used for air conditioning and heating, to prevent the reduction of the evaporation amount of the refrigerant generated when the outside air temperature is low. At the same time, the refrigerant in the liquid state inside the main body is evaporated at a high temperature to the gaseous refrigerant, thereby enabling the heat pump system to operate normally, and increasing the efficiency of the heat pump system.
