상기와 같은 구성을 갖는 히트펌프의 작동관계를 설명하면 다음과 같다.Referring to the operation of the heat pump having the configuration as described above are as follows.
상기 히트펌프는 정순환모드의 냉방운전시 압축기(1)의 작동에 의해 냉매는 화살표 A의 방향으로 압축기(1)-사방밸브(5)-실외측열교환기(2)-팽창기구(3)-실내측열교환기(4)-사방밸브(5)-압축기(1)의 순서를 거치면서 유동되고, 실내측열교환기(4)가 증발기의 역할을 하면서 차가운 공기를 실내로 토출하여 냉방상태로 유지한다.The heat pump is operated by the compressor (1) during the cooling operation in the forward circulation mode, the refrigerant in the direction of the arrow A compressor (1)-four-way valve (5)-outdoor side heat exchanger (2)-expansion mechanism (3)- It flows through the sequence of the indoor side heat exchanger (4), the four-way valve (5) and the compressor (1), and the indoor side heat exchanger (4) acts as an evaporator and discharges cold air into the room to maintain the cooling state. do.
그리고 역순환모드의 난방운전시에는 사방밸브(5)의 방향을 변환시켜 냉매의 유동방향을 냉방운전시의 역방향으로(화살표 B) 흐르도록 하여 실내측열교환기(4)가 응축기의 역할을 하면서 더운 공기를 실내로 토출하여 난방상태로 유지하는 바, 히트펌프는 상기 사방밸브(5)의 방향을 변환시켜 실내에 설치되어 있는 실내측열교환기(4)의 역할을 변환시켜 실내를 냉/난방시킨다.During the heating operation in the reverse circulation mode, the direction of the four-way valve 5 is changed to flow the refrigerant in the reverse direction (arrow B) during the cooling operation, and the indoor heat exchanger 4 serves as a condenser. The hot pump discharges hot air into the room to maintain the heating state. The heat pump changes the direction of the four-way valve 5 to change the role of the indoor side heat exchanger 4 installed in the room to cool / heat the room. Let's do it.
도 3a 및 도 3b는 상기 구성과 작용을 이루는 히트펌프의 실내측 및 실외측열교환기에서 냉매와 공기의 유동상태를 도시한 것으로서, 실외측열교환기를 대표적으로 도시하였다. 2는 실외측열교환기로서 제 1냉매관(8a)과 연결되어 냉매가 순환되는 열교환기 1열부(2a)와, 일 측은 상기 열교환기 1열부(2a)와 연결되고 타측은 제 2냉매관(8b)과 연결되어 냉매가 순환되는 열교환기 2열부(2b)와, 상기 열교환기 1열부,2열부(2a,2b)의 외측에서 외부와 열교환되는 방열핀(2c)으로 구성되었으며, 6은 공기의 유동을 발생시키는 실외팬이고, 상기 순환되는 냉매와 공기의 유동상태를 화살표로서 도시하였다.3A and 3B illustrate the flow states of the refrigerant and the air in the indoor side and the outdoor side heat exchanger of the heat pump constituting the above-described configuration, and are representatively shown in the outdoor side heat exchanger. 2 is an outdoor side heat exchanger, which is connected to the first refrigerant pipe 8a to circulate the refrigerant and the first heat exchanger 2a, one side of which is connected to the first heat exchanger 2a, and the other side of the second refrigerant pipe ( It is composed of a heat exchanger second row portion (2b) connected to 8b) to circulate the refrigerant, and heat dissipation fins (2c) that heat exchange with the outside from the outside of the heat exchanger first row portion, the second row portion (2a, 2b), 6 is the air of An outdoor fan for generating a flow, and the flow state of the circulating refrigerant and air is shown as an arrow.
도 3a는 정순환모드의 냉방운전시 냉매와 공기의 유동상태를 도시한 것으로서, 냉매는 제 1냉매관(8a)을 통하여 열교환기 1열부(2a)로 유입되고, 상기 1열부(2a)를 순환하여 2열부(2b)로 들어가며, 2열부(2b)를 순환한 후 제 2냉매관(8b)을 통하여 유출된다. 한편, 실외팬(6)에 의하여 냉매의 유동방향과는 반대방향으로 공기의 유동이 발생되어 냉매와 공기는 대향류를 형성한다.3A illustrates a flow state of the refrigerant and air during the cooling operation in the forward circulation mode. The refrigerant flows into the heat exchanger first row portion 2a through the first refrigerant pipe 8a and circulates through the first row portion 2a.

On the other hand, the flow of air is generated in the direction opposite to the flow direction of the refrigerant by the outdoor fan 6, the refrigerant and the air to form a counter flow.
그러나, 도 3b와 같이 역순환모드의 난방운전으로 운전모드가 변환되는 경우에는 냉매의 유동방향은 상기 냉방운전의 경우와는 반대가 되어 제 2냉매관(8b)-열교환기 2열부(2b)-열교환기 1열부(2a)-제 1냉매관(8a)으로 유동되고, 공기의 유동은 실외팬(6)에 의해 발생되므로 결과적으로 냉매와 공기는 같은 방향으로 유동하게 된다.However, when the operation mode is switched to the heating operation in the reverse circulation mode as shown in FIG. 3B, the flow direction of the refrigerant is opposite to that of the cooling operation, so that the second refrigerant pipe 8b-the heat exchanger second row portion 2b -Heat exchanger 1 column part 2a-It flows to the 1st refrigerant pipe 8a, and the flow of air is generated by the outdoor fan 6, As a result, a refrigerant | coolant and air flow in the same direction.
즉, 종래의 히트펌프는 운전모드가 역순환모드로 변환되는 경우에는 열교환기 내부를 흐르는 냉매의 유동방향이 변경되어 공기의 유동방향에 대하여 대향류를 형성할 수 없으므로 열교환기의 효율이 저하되는 문제점이 있었다.That is, in the case of the conventional heat pump, when the operation mode is converted to the reverse circulation mode, the flow direction of the refrigerant flowing inside the heat exchanger is changed so that a counter flow cannot be formed in the flow direction of the air. There was a problem.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 히트펌프의 운전모드가 역순환모드로 변환되어도 열교환기에서 냉매와 공기의 유동방향이 항상 반대가 되는 대향류를 형성하여 열교환기의 효율을 향상시킬 수 있는 히트펌프 열교환기의 대향류 발생장치를 제공하는 데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is that the flow direction of the refrigerant and air in the heat exchanger is always reversed even if the operation mode of the heat pump is converted to the reverse circulation mode. The present invention provides a counterflow generator of a heat pump heat exchanger capable of forming countercurrent to improve the efficiency of the heat exchanger.

한편, 역순환모드의 난방운전시에는 압축기(1)의 작동에 의해 냉매가 화살표 B의 방향으로 압축기(1)-사방밸브(5)-실내측열교환기(4)-팽창기구(3)-실외측열교환기(2)-사방밸브(5)-압축기(1)의 순서를 거치면서 유동되고, 실내측열교환기(4)가 응축기의 역할을 하면서 실내를 난방시키는 바, 상기 실외측열교환기(2)에서는 도 4에 도시된 바와 같이, 냉매유동반전수단(10)의 제 1개폐밸브(13)와 제 2개폐밸브(14)는 열리고, 제 3개폐밸브(15)와 제 4개폐밸브(16)는 닫혀서 제 1,2연결관(11,12)은 개통되므로 냉매는 제 1,2냉매관(8a,8b)의 점선으로 표시된 화살표 방향으로 유동되므로, 난방운전으로 운전모드가 역순환으로 변환되어도 항상 도 3a와 같이 냉매와 공기의 유동방향이 반대가 되는 대향류가 형성된다.On the other hand, during the heating operation in the reverse circulation mode, the refrigerant is operated in the direction of arrow B by the operation of the compressor 1, and the compressor 1, the four-way valve 5, the indoor side heat exchanger 4, the expansion mechanism 3, The outdoor side heat exchanger (2)-the four-way valve (5)-the compressor (1) flows in the sequence, the indoor side heat exchanger (4) acts as a condenser to heat the room, the outdoor side heat exchanger In (2), as shown in FIG. 4, the first open / close valve 13 and the second open / close valve 14 of the refrigerant flow inverting means 10 are opened, and the third open / close valve 15 and the fourth open / close valve. 16 is closed so that the first and second connection pipes 11 and 12 are opened so that the refrigerant flows in the direction of the arrow indicated by the dotted lines of the first and second refrigerant pipes 8a and 8b. Even if it is converted to, as shown in FIG.
이상에서 설명한 바와 같이, 본 발명에 의한 히트펌프 열교환기의 대향류장치는 냉매유동반전수단을 채택함으로써, 히트펌프의 운전모드가 역순환모드로 변환되어 냉매의 유동방향이 바뀌어도 열교환기 내부에서는 정순환모드와 동일한 방향으로 유동되어 열교환기에서 냉매와 공기의 유동방향이 항상 반대가 되는 대향류를 형성시켜 열교환기의 효율을 향상시킬 수 있는 효과가 있다.As described above, the counter flow device of the heat pump heat exchanger according to the present invention employs a refrigerant flow inverting means, so that the operation mode of the heat pump is converted into the reverse circulation mode so that the refrigerant flows in the heat exchanger even if the flow direction of the refrigerant is changed. Since the flow in the same direction as the mode to form a counter flow in which the flow direction of the refrigerant and air in the heat exchanger is always opposite, there is an effect that can improve the efficiency of the heat exchanger.
