Description
図1は、本発明の一実施例を示す図であり、同図1において符号1〜13は図3、4に示した従来例のものと基本的に共通の構成を示している。
そして、本実施例のものにおいては圧縮機1の冷媒吐出管6と熱回収用熱交換器5を出た後の冷媒吸入管7との間を、途中に第1開閉弁14を備えるバイパス配管15で接続するとともに、バイパス配管15と分岐した後の冷媒吐出管6に第2開閉弁16を設置し、これら開閉弁14、16よりなる開閉弁装置24を制御するための温度検知器17を、例えばアキュムレータ13に取付けている。
この温度検知器17に対し、蒸発温度検知のために温度検知器18を熱回収用熱交換器冷媒配管5aに、あるいは排温水温度検知のために温度検知器19を排温水管12に取り付けている。なお、冷媒には高温冷媒であるR−245faを採用するのが好適である。
