Description

가스구동히트펌프의 냉각수 순환장치{Engine Coolant System in Gas Engine Driven Heat Pump}Engine Coolant System in Gas Engine Driven Heat Pump

본 발명은 가스구동히트펌프의 냉각수 순환장치에 관한 것으로서, 특히 가스엔진에서 배출된 냉각수가 냉매와 열교환하는 열교환기로 유동하는 유량을 신뢰성 있게 제어할 수 있도록 구성한 것이다.The present invention relates to a cooling water circulation device of a gas driven heat pump, and in particular, is configured to reliably control the flow rate of the cooling water discharged from the gas engine to the heat exchanger that exchanges heat with the refrigerant.

도 1은 종래 기술에 따른 가스구동히트펌프의 냉각수 순환장치를 나타낸 개략도이다.1 is a schematic view showing a cooling water circulation device of a gas driven heat pump according to the prior art.

도 1에 도시된 바와 같이, 가스엔진(1)에서 배출된 냉각수는 왁스밸브(5)로 유입된다. 왁스밸브(5)로 유입된 냉각수의 온도가 왁스밸브(5)의 작동온도 이상이면 제1 배관(21)을 통해 삼방변(7)으로 유동하고, 만약 냉각수의 온도가 왁스밸브(5)의 작동온도 미만이면 제2 배관(22)을 통해 다시 가스엔진(1)으로 유입된다.As shown in FIG. 1, the cooling water discharged from the gas engine 1 flows into the wax valve 5. If the temperature of the coolant flowed into the wax valve 5 is greater than the operating temperature of the wax valve 5, it flows through the first pipe 21 to the three-way side 7, and if the temperature of the coolant is If it is less than the operating temperature is introduced to the gas engine 1 through the second pipe (22) again.

한편, 여름철 냉방운전 시에 삼방변(7)으로 유입된 냉각수가 제4 배관(24)을 따라 방열기(8)로 유동하면서 배기가스열교환기(3)와 가스엔진(1)에서 얻은 열을 방열기(8)에서 외부로 방열하고, 겨울철 난방운전 시에는 삼방변(7)으로 유입된 냉각수가 제3 배관(23)을 따라 판형열교환기(10)로 유입되어 냉매와 열교환한다.On the other hand, the coolant flowing into the three-sided (7) during the summer cooling operation flows to the radiator (8) along the fourth pipe (24) while radiating heat from the exhaust gas heat exchanger (3) and the gas engine (1) Radiating to the outside in (8), during the winter heating operation, the coolant introduced into the three-way (7) flows into the plate heat exchanger 10 along the third pipe 23 to exchange heat with the refrigerant.

이와 같은 냉각수 순환장치를 갖는 가스구동히트펌프에 있어서, 왁스밸브(5)는 냉각수의 온도에 의해 냉각수의 진행방향을 결정하기 때문에, 왁스밸브(5)의 작동온도와 냉각수 온도와의 상관관계가 중요하다. In the gas-driven heat pump having such a coolant circulation device, since the wax valve 5 determines the direction of the coolant by the temperature of the coolant, the correlation between the operating temperature of the wax valve 5 and the coolant temperature is different. It is important.

하지만, 종래에 사용되는 왁스밸브의 작동온도는 70℃이고, 냉각수의 최대온도는 70℃ 전후이므로, 왁스밸브 개도가 열리는 70℃에서 왁스밸브가 열렸다 닫혔다하면서 냉각수 유량의 변화가 심해서 제어 신뢰성이 떨어진다.However, since the operating temperature of the conventional wax valve is 70 ℃ and the maximum temperature of the cooling water is around 70 ℃, the wax valve is opened and closed at 70 ℃ to open the wax valve opening, while the flow rate of the coolant is severely changed, the control reliability is poor. .

난방 시에 왁스밸브(5)에서 배출되는 냉각수 전체가 판형열교환기(10)로 유동하는 것이 바람직하지만, 실제 가스구동히트펌프의 냉각수 유량을 측정해보면, 판형열교환기(10)로 유동하는 냉각수의 유량은 왁스밸브(5)로 유입되는 냉각수의 30부피%정도밖에 되지 않고, 나머지 70부피%의 냉각수는 제2 배관(22)을 통해 가스엔진(1)으로 유입된다.Although it is preferable that the entire cooling water discharged from the wax valve 5 flows to the plate heat exchanger 10 during heating, the flow rate of the coolant flowing to the plate heat exchanger 10 is measured by measuring the flow rate of the cooling water of the actual gas-driven heat pump. The flow rate is only about 30% by volume of the cooling water flowing into the wax valve 5, and the remaining 70% by volume of the cooling water flows into the gas engine 1 through the second pipe 22.

이와 같이 난방운전 시에, 판형열교환기(10)로 유동하는 냉각수의 유량이 작음에 따라 가스엔진(1)의 냉각효과가 떨어진다는 단점이 있다. 일반적으로 냉각수의 열은 판형열교환기에서 대부분 회수되는데, 판형열교환기로 유입되는 냉각수의 유량이 작음에 따라 판형열교환기에서 냉매로 회수되는 열량이 준다.As such, when the heating operation is performed, the cooling effect of the gas engine 1 is lowered as the flow rate of the cooling water flowing into the plate heat exchanger 10 is small. In general, the heat of the cooling water is mostly recovered in the plate heat exchanger, and as the flow rate of the cooling water flowing into the plate heat exchanger is small, the amount of heat recovered as the refrigerant in the plate heat exchanger is given.

도 1에 도시된 도면부호 중 미설명된 도면부호 9는 펌프이고, 11은 실내기이고, 13은 실외기이며, 15는 사방변 그리고 17은 팽창밸브이다.Reference numeral 9 of the reference numerals shown in FIG. 1 is a pump, 11 is an indoor unit, 13 is an outdoor unit, 15 is a four-sided valve, and 17 is an expansion valve.

본 발명은 앞에서 설명한 바와 같은 종래의 기술의 문제점을 해결하기 위하여 발명된 것으로서, 판형열교환기로 유동하는 냉각수의 유량을 신뢰성 있게 제어함으로써, 가스구동히트펌프의 성능을 향상시키며 안정화할 수 있게 구성한 가스구동히트펌프의 냉각수 순환장치를 제공하는 데 그 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, by reliably controlling the flow rate of the cooling water flowing to the plate heat exchanger, the gas drive configured to improve and stabilize the performance of the gas drive heat pump It is an object of the present invention to provide a cooling water circulator of a heat pump.

또한, 본 발명의 가스구동히트펌프의 냉각수 순환장치는 고가인 삼방변을 대신하여 저가인 전동밸브를 사용함으로써, 비용을 절감할 수 있다.In addition, the cooling water circulation device of the gas driven heat pump of the present invention can reduce the cost by using a low-cost electric valve in place of the expensive three-way.

상기와 같은 목적을 달성하기 위한 본 발명의 가스구동히트펌프의 냉각수 순환장치는 가스엔진에서 배출된 냉각수가 왁스밸브로 유입되게 상기 가스엔진에서 상기 왁스밸브까지 연장된 제1 배관과, 상기 제1 배관 중간에서 냉매/냉각수 열교환기로 연장된 제3 배관과, 상기 왁스밸브에서 방열기로 연장된 제4 배관과, 상기 왁스밸브에서 상기 가스엔진으로 연장된 제2 배관 및, 상기 제3 배관의 중간에 설치되어 상기 제3 배관의 개도를 제어하는 밸브를 포함하는 것을 기술적 특징으로 한다.The cooling water circulation device of the gas drive heat pump of the present invention for achieving the above object includes a first pipe extending from the gas engine to the wax valve so that the cooling water discharged from the gas engine flows into the wax valve; A third pipe extending from the middle of the pipe to the refrigerant / coolant heat exchanger, a fourth pipe extending from the wax valve to the radiator, a second pipe extending from the wax valve to the gas engine, and a third pipe in the middle of the third pipe It is characterized in that it comprises a valve installed to control the opening degree of the third pipe.

또한, 본 발명의 바람직한 실시예에 따르면, 상기 밸브는 전동밸브이다.According to a preferred embodiment of the present invention, the valve is an electric valve.

또한, 본 발명의 바람직한 실시예에 따르면, 상기 냉매/냉각수 열교환기는 판형열교환기이다.Further, according to a preferred embodiment of the present invention, the refrigerant / coolant heat exchanger is a plate heat exchanger.

또한, 본 발명의 바람직한 실시예에 따르면, 상기 열교환기에서 연장된 배관 과 상기 방열기에서 연장된 배관은 상기 제2 배관으로 연결되어 냉각수가 합류하여 상기 가스엔진으로 유입된다.In addition, according to a preferred embodiment of the present invention, the pipe extending from the heat exchanger and the pipe extending from the radiator are connected to the second pipe and the cooling water joins and flows into the gas engine.

또한, 본 발명의 바람직한 실시예에 따르면, 상기 가스엔진에서 배출된 냉각수 중 50vol% 이상이 상기 제3 배관을 통해 상기 냉매/냉각수 열교환기로 유동하며, 상기 밸브의 개도에 의해 상기 냉매/냉각수 열교환기로 유동하는 냉각수의 유량이 제어된다.Further, according to a preferred embodiment of the present invention, at least 50 vol% of the cooling water discharged from the gas engine flows to the refrigerant / coolant heat exchanger through the third pipe, and to the refrigerant / coolant heat exchanger by opening the valve. The flow rate of the flowing coolant is controlled.

앞서 설명한 바와 같이, 본 발명의 가스구동히트펌프의 냉각수 순환장치는 난방운전 시에 판형열교환기를 지나는 냉각수 유량 및 열량 제어성능을 향상시킴으로써, 가스구동히트펌프의 성능을 향상시킨다는 장점이 있다.As described above, the cooling water circulation device of the gas driven heat pump of the present invention has an advantage of improving the performance of the gas driven heat pump by improving the cooling water flow rate and calorie control performance passing through the plate heat exchanger during the heating operation.

아래에서는 본 발명에 따른 가스구동히트펌프의 냉각수 순환장치의 양호한 실시예를 첨부한 도면을 참조로 하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the cooling water circulation device of the gas driven heat pump according to the present invention will be described in detail.

도면에서, 도 2는 본 발명에 따른 가스구동히트펌프의 냉각수 순환장치를 나타낸 개략도이다.2 is a schematic view showing a cooling water circulation device of a gas driven heat pump according to the present invention.

도 2에 도시된 바와 같이, 가스엔진(101)에서 배출된 냉각수는 제1 배관(121)을 따라 왁스밸브(105)로 유입된다. 왁스밸브(105)로 유입된 냉각수는 그 온도에 따라 제2 배관(122)을 따라 가스엔진(101)으로 유입되거나 또는 제4 배관(124)을 따라 방열기(108)로 유동하게 된다.As shown in FIG. 2, the coolant discharged from the gas engine 101 flows into the wax valve 105 along the first pipe 121. The coolant introduced into the wax valve 105 flows into the gas engine 101 along the second pipe 122 or flows to the radiator 108 along the fourth pipe 124 according to the temperature.

한편, 제1 배관(121)의 중간에서 제3 배관(123)이 분기되어 판형열교환기(110)로 연장되는데, 제3 배관(123)에는 전동밸브(107)가 장착되어 제3 배관(123)의 개도를 조절한다.Meanwhile, the third pipe 123 branches in the middle of the first pipe 121 and extends to the plate heat exchanger 110. The third pipe 123 is equipped with an electric valve 107 and the third pipe 123. Adjust the opening of).

아래에서는 이와 같이 구성된 가스구동히트펌프의 냉방운전 시와 난방운전 시의 냉각수 유동관계에 대해 설명한다.The following describes the flow relationship of the coolant during the cooling operation and the heating operation of the gas driven heat pump configured as described above.

여름철 냉방운전 시에는, 전동밸브(107)를 닫아 가스엔진(101)에서 배출되는 냉각수 전체가 제1 배관(121)을 통해 왁스밸브(105)로 유동하게 한다. 냉각수 온도가 왁스밸브(105)의 작동온도 미만이면 냉각수는 제2 배관(122)을 통해 펌프(109)와 배기가스열교환기(103)를 거쳐 가스엔진(101)으로 유입되고, 냉각수 온도가 왁스밸브(105)의 작동온도 이상이면 냉각수는 제4 배관(124)을 통해 방열기(108)를 거쳐 가스엔진(101)으로 유입된다.During the summer cooling operation, the electric valve 107 is closed to allow the entire cooling water discharged from the gas engine 101 to flow into the wax valve 105 through the first pipe 121. If the coolant temperature is lower than the operating temperature of the wax valve 105, the coolant flows into the gas engine 101 through the pump 109 and the exhaust gas heat exchanger 103 through the second pipe 122, the coolant temperature is wax If the operating temperature of the valve 105 or more, the coolant flows into the gas engine 101 through the radiator 108 through the fourth pipe 124.

한편, 겨울철 난방운전 시에는 냉각수 온도 또는 냉각수 순환시스템의 부하에 따라 전동밸브(107)의 개도를 완전히 개방하였을 때에, 제3 배관(123)을 따라 판형열교환기(110)로 유동하는 냉각수의 유량이 50vol% 이상 확보되며, 상대적으로 왁스밸브(105)를 통과해 가스엔진(101)으로 유입되는 냉각수의 유량은 50vol% 미만이 되도록 배관저항을 설계하여 제어한다.Meanwhile, during the heating operation in winter, when the opening degree of the electric valve 107 is completely opened according to the cooling water temperature or the load of the cooling water circulation system, the flow rate of the cooling water flowing to the plate heat exchanger 110 along the third pipe 123. The 50 vol% or more is secured, and the pipe resistance is designed and controlled so that the flow rate of the coolant flowing through the wax valve 105 into the gas engine 101 is less than 50 vol%.

따라서 가스엔진(101)에서 배출된 냉각수 중 50vol% 이상은 판형열교환기(110)로 유입되고, 50vol% 미만은 제2 배관(122) 또는 제4 배관(124)을 따라 방 열기(108)를 거쳐 가스엔진(101)으로 유입된다.Therefore, 50 vol% or more of the cooling water discharged from the gas engine 101 flows into the plate heat exchanger 110, and less than 50 vol% of the cooling water is transferred to the heat exchanger 108 along the second pipe 122 or the fourth pipe 124. After passing through the gas engine 101.

이와 같이 난방운전 시에 가스엔진(101)에서 배출되는 냉각수 중 50vol% 이상의 냉각수가 판형열교환기(110)를 거쳐 냉매와 열교환 후에 가스엔진(101)으로 유입되기 때문에, 가스엔진으로 유입되는 냉각수의 온도는 제2 배관(122) 또는 제4 배관(124)을 따라 유동하는 냉각수의 온도보다 상대적으로 낮다. Since the cooling water of 50 vol% or more of the cooling water discharged from the gas engine 101 during the heating operation is introduced into the gas engine 101 after heat exchange with the refrigerant through the plate heat exchanger 110, the cooling water flowing into the gas engine The temperature is relatively lower than the temperature of the cooling water flowing along the second pipe 122 or the fourth pipe 124.

결과적으로, 난방 운전시에 냉각수의 최대 온도가 왁스밸브(105)가 반응하는 최소온도보다 낮도록 하면, 냉각수가 방열기(108)로 흘러 열을 식히지 않고 바로 가스엔진(101)으로 보낼 수 있어 종래기술과 같이 난방모드로 운전할 수 있으며, 판형열교환기(110)로 가는 냉각수의 유량을 줄이고자 할 경우에는 전동밸브(107)의 개도를 조절하여 50vol% 이하로 원하는 유량으로 제어 가능하다.As a result, when the maximum temperature of the cooling water is lower than the minimum temperature at which the wax valve 105 reacts during the heating operation, the cooling water flows to the radiator 108 and can be directly sent to the gas engine 101 without cooling the heat. As in the prior art, it can be operated in a heating mode, and if it is desired to reduce the flow rate of the cooling water going to the plate heat exchanger 110, it is possible to control the desired flow rate to 50 vol% or less by adjusting the opening degree of the electric valve 107.

종래에는 난방운전 시에, 판형열교환기(10)로 유입되는 냉각수의 양을 신뢰성이 떨어지는 왁스밸브(5)가 제어하였으나, 본 발명에 따른 가스구동히트펌프는 신뢰성 높은 전동밸브(107)로 제어됨으로써, 가스구동히트펌프의 열량 제어성능이 우수하다.Conventionally, in the heating operation, the amount of cooling water flowing into the plate heat exchanger 10 is controlled by the wax valve 5 having low reliability, but the gas-driven heat pump according to the present invention is controlled by a highly reliable electric valve 107. As a result, the calorie control performance of the gas driven heat pump is excellent.

또한, 종래 기술에서는 고가의 삼방변을 사용하였으나, 본 발명에서는 저가의 전동밸브를 사용함으로써, 비용절감의 효과가 있다.In addition, in the prior art, an expensive three-way valve is used, but in the present invention, by using an inexpensive electric valve, there is an effect of reducing the cost.
