従来、ヒートポンプの冷媒と冷却水との間で熱を交換し、この冷却水によって空調装置の冷房または暖房の運転の一部の機能を担わせる技術が幾つか提案されている(例えば、特許文献1又は2を参照)。 Conventionally, several technologies have been proposed in which heat is exchanged between the refrigerant of the heat pump and the cooling water, and the cooling water performs a part of the cooling or heating operation of the air conditioner (for example, Patent Documents). 1 or 2).
しかしながら、冷媒を流す回路と冷却水を流す回路とを備えた空調システムにおいては、冷媒を流す複数の機器と冷却水を流す複数の機器とでシステムの構成部品数が多くなる。よって、このような空調システムでは、システム全体が大型化して煩雑な構成になるという課題がある。 However, in an air conditioning system including a circuit for flowing refrigerant and a circuit for flowing cooling water, the number of components of the system increases with a plurality of devices for flowing the refrigerant and a plurality of devices for flowing the cooling water. Therefore, in such an air conditioning system, there is a problem that the entire system becomes large and has a complicated configuration.

The
アキュムレータ42は、液相と気相との混合となっている冷媒を分離して、気相の冷媒のみをコンプレッサ41に供給する。
The
開閉弁43は、開閉動作によって、室外熱交換器10から送り出される冷媒を、エバポレータ48側へ送るか、或いは、エバポレータ48を介さずにアキュムレータ42へ送るかの切り替えを行う。開閉弁43は、暖房運転時に開とされて冷媒を流し、冷房運転時に閉とされて冷媒を流さない。
The on-off

エバポレータ48は、内部に低温の冷媒を流し、且つ、複数のフィン式放熱板の間に送風路200内の空気を流すことによって、空気の熱を冷媒へ移動させる。エバポレータ48は、暖房運転時には冷媒が流されず通過する空気になんら作用を及ぼさず、冷房運転時に冷媒が流されて通過する空気を冷却する。
The
ヒーターコア50は、内部に冷却水を流し、且つ、冷却水によって熱せられる複数のフィン式放熱板の間に送風路200内の空気を流すことによって、冷却水の熱を空気へ放出する。ヒーターコア50は、暖房運転時には熱せられた冷却水が流れて通過する空気を過熱する。また、ヒーターコア50は、冷房運転時に冷却水が止められるか、或いは、冷暖切替ドア51が空気の通過を遮ることで、空気になんら作用を及ぼさない。
