그리고 도면중에서 부호 22a는 응축기 팬, 22b는 증발기 팬을 도시한 것이다.In the figure, reference numeral 22a denotes a condenser fan and 22b denotes an evaporator fan.

상기와 같이 구성될 수 있는 본 발명의 냉·난방기(1)는 다음과 같이 난방과 냉방을 선택적으로 행할 수 있는 것으로서, The air conditioner (1) of the present invention that can be configured as described above can selectively perform heating and cooling as follows,

우선 본 발명의 냉·난방기(1)를 사용하여 난방을 행할 시에는, 응축기(3)에서 응축된 냉매액을 전자밸브(6)가 설치된 이송관(7)을 경유하여 증발기(5)에 직접 이송시켜 팽창밸브(11)를 통해 증발하는 냉매의 증발을 돕고 자신은 다시 한번 응축되어(과냉각되어) 이송관(10)을 통해 밸브(9)를 경유, 수액기(8)로 들어가서 계속 이송관(12)을 통해 팽창밸브(11)에서 팽창, 증발이 일어남으로서 증발이 더욱더 잘 이루어 질 수 있게 해주고, 압축기(2)로 재흡입되는 회로로 구성된다.First, when heating is performed using the air conditioner (1) of the present invention, the refrigerant liquid condensed in the condenser (3) directly to the evaporator (5) via the transfer pipe (7) provided with the solenoid valve (6). It transfers to help the evaporation of the refrigerant evaporating through the expansion valve (11) and condenses (supercooled) once again, enters the receiver (8) via the valve (9) through the conveying pipe (10) and continues the conveying pipe The expansion and evaporation occurs in the expansion valve 11 through 12 to make the evaporation even better, and is composed of a circuit that is sucked back into the compressor 2.

한편, 냉방 시에는 응축기(3)에서 응축된 냉매가 전자밸브(20)가 설치된 이송관(21)을 경유, 수액기(8)로 들어가고 이송관(12)을 통해 팽창밸브(11)에서 팽창, 증발하도록 하고 있으며, 이때 응축기(3)에서 응축되는 냉매의 응축압력이 상승하여 응축이 불완전할 경우, 전자밸브(16)를 열어 이송관(18)을 통해 팽창밸브(17)에서 팽창, 증발시켜 응축냉매의 응축을 돕게 되어 응축압력을 조절, 증발기(5)에서 증발이 더욱더 잘 될 수 있도록 하여 냉방효율을 높일 수 있다.On the other hand, during cooling, the refrigerant condensed in the condenser 3 enters the receiver 8 through the transfer pipe 21 in which the solenoid valve 20 is installed, and expands in the expansion valve 11 through the transfer pipe 12. In this case, when the condensation pressure of the refrigerant condensed in the condenser 3 rises and the condensation is incomplete, the solenoid valve 16 is opened to expand and evaporate from the expansion valve 17 through the transfer pipe 18. By helping to condensation of the condensation refrigerant to control the condensation pressure, the evaporator (5) can be improved even better so that the cooling efficiency.

그리고 난방 시에는 응축기 팬(22a)은 실내쪽으로의 송풍방향이 설정되며, 증발기 팬(22b)은 실외쪽으로 송풍되도록 설정된다.In the heating process, the condenser fan 22a is set to a blowing direction toward the indoor side, and the evaporator fan 22b is set to blow to the outdoor side.

또한, 냉방 시에는 전기와는 역으로 팬(22a,22b) 방향을 돌리면 응축기 팬(22a)은 실외쪽으로, 증발기 팬(22b)은 실내쪽으로 설정되어 회로의 변환없이도 냉·난방을 선택적으로 수행할 수 있는 것이다.In addition, when cooling, the fan 22a and 22b are turned in the opposite direction to electricity, and the condenser fan 22a is set to the outdoor side and the evaporator fan 22b is set to the indoor side to selectively perform cooling and heating without changing a circuit. It can be.

그리고 도 3과 같이 냉·난방기의 장치를 배관할 경우 팬(22a,22b) 방향의 변환없이도 냉·난방이 선택적으로 가능한 것이다.And when piping the apparatus of the air-conditioner, as shown in Figure 3, it is possible to selectively cool and heat without changing the fan 22a, 22b direction.

이상에서 상세히 살펴 본 바와 같이 본 발명에서 제공하는 냉·난방기(1)는 난방 시 응축기에서 응축된 냉매액의 열원을 증발기에서 증발하는 냉매에 계속 제 공함으로서 증발을 돕고 자신은 과냉각되어 수액기로 들어가므로 더욱더 증발에 도움을 주어 난방효율이 증가하고 증발기 코일의 제상문제도 해결이 가능하다.As described in detail above, the air conditioner (1) provided by the present invention continuously provides the heat source of the refrigerant liquid condensed in the condenser during the heating to the refrigerant evaporating from the evaporator, thereby assisting evaporation and entering the receiver into the receiver. Therefore, it helps to evaporate more and more, thus increasing the heating efficiency and solving the problem of defrost of the evaporator coil.

그리고 냉방 시에는 응축압력의 상승시 응축되는 냉매를 재차 증발시켜 응축을 도우므로 증발기에서 증발을 촉진하여 냉방효율을 증가시키며 동절기에 충진된 냉매의 냉매 충진량의 과다에 따른 응축압력의 상승도 압력이 일정 이상시 냉매를 응축기에 재차 증발시키므로 압력을 조정할 수 있다.In case of cooling, the condensed refrigerant is evaporated again to increase the condensation pressure. Therefore, the evaporator promotes evaporation to increase the cooling efficiency. The pressure can be adjusted because the refrigerant is evaporated again in the condenser after a certain time.

또한, 일체형으로 제작하여 설치하면 실내에 증발기와 응축기가 설치되므로 실내의 공기로 응축 및 증발에 사용함으로서 시간이 흐를수록 응축과 증발이 점점 더 잘 일어나는 장점도 가지는 등 그 기대되는 효과가 다대한 발명이다.In addition, since the evaporator and condenser are installed indoors when installed and installed in one piece, the condensation and evaporation is used as the indoor air. to be.
