Description
図1は、本実施形態に係るガスヒートポンプ式の空気調和装置1を示す回路図である。同図に示されるように、空気調和装置1は、室外機10と、複数の室内機30とを備えて構成されている。
まず、冷房運転時において、圧縮機12の吐出管12bを出た冷媒は、四方弁14を通過した後、凝縮器として機能する室外機熱交換器15に導かれる。室外機熱交換器15において、冷媒は室外の空気(外気)により熱を奪われ、凝縮・液化する。その後、逆止弁21を介して室内機30に導かれた冷媒は、電子膨張弁32において減圧されるとともに、蒸発器として機能する室内機熱交換器31において、室内の空気の熱を奪い気化する。その後、冷媒は、四方弁14及びアキュームレータ18を介して圧縮機12の吸入管12aに戻る。以上の過程を経ることで、室内が冷房される。
(1)本実施形態では、圧縮機12は、ガスエンジン11に常時一体回転するように駆動連結され、該ガスエンジン11との間に動力伝達を断接するクラッチなどを設ける必要がないため、部品点数及びコストを削減することができる。そして、冷却液温度Twが目標温度Twtを下回るときには(ガスエンジン11の冷間状態)、制御装置41によりガスエンジン11は暖房能力に基づく最大を含む所定範囲の回転速度NMで暖機運転されるため、冷却液温度Twを速やかに上昇させることができる。この際、圧縮機12の冷媒圧力に異常が生じて、吐出管12bの冷媒圧力が高側所定圧力PHを超え、あるいは吸入管12aの冷媒圧力が低側所定圧力PLを下回ったときは、ホットガス弁17により吸入管12a及び吐出管12bの間が連通されることで、圧縮機12の冷媒圧力の異常が解消される。従って、圧縮機12の暖機運転中、圧縮機12の冷媒圧力の異常を解消するための該圧縮機12の停止、即ちガスエンジン11の停止が不要とされる。
・前記実施形態においては、ガスエンジン11及び圧縮機12の駆動連結は、常時一体回転するのであれば、これらの出力軸及び入力軸を伝動ベルト等を介して駆動連結してもよい。
