Abstract

본 발명은 냉난방 겸용 룸에어콘에 관한 것으로서, 난방시 난방효율이 떨어지는 것을 방지하기 위해, 실내열교환기(1)와 실외열교환기(4) 중간에 2방향밸브(21)가 모세관(5)과 병열로 연결되고, 상기 실외열교환기(4)의 코일 끝단에 일정 압력에서 ON/OFF되는 압력스위치(22)가 연결되며, 상기 압력스위치(22)에 2방향밸브코일(23)이 직렬로 연결되어, 운전중에 냉매가스의 압력이 떨어지면, 압력스위치(22)가 ON되어 2방향밸브코일(23)에 전원이 투입되고, 이로인해 싸이클회로가 열리게 되어 실내열교환기(1)에서 응축된 고온의 냉매가스 일부가 모세관(5)을 통하지 않고 직접 실외열교환기(4)로 유입되도록 하는 냉난방겸용 룸에어콘의 냉동싸이클이다.The present invention relates to a room air conditioner for both heating and cooling, wherein a two-way valve (21) is in parallel with the capillary tube (5) between the indoor heat exchanger (1) and the outdoor heat exchanger (4) in order to prevent the heating efficiency from dropping during heating. Is connected to, the pressure switch 22 which is ON / OFF at a constant pressure is connected to the coil end of the outdoor heat exchanger (4), the two-way valve coil (23) is connected in series to the pressure switch (22) When the pressure of the refrigerant gas drops during operation, the pressure switch 22 is turned on, and the power is supplied to the two-way valve coil 23. Thus, the cycle circuit is opened so that the high temperature refrigerant condensed in the indoor heat exchanger (1). It is a refrigeration cycle of a room air-conditioner for cooling and heating that allows a portion of gas to flow directly into the outdoor heat exchanger 4 without passing through the capillary tube 5.
