Description
プ式給湯装置を提供できる。
図1及び図2は、第1の実施の形態におけるヒートポンプ式給湯装置と運転制御を示したものである。図1は、圧縮機1、水と冷媒とを熱交換させる給湯用放熱器2、第一の減圧装置3、冷媒と外気とを熱交換させる中間熱交換器10、第二の減圧装置11、冷媒と外気とを熱交換させる蒸発器4を冷媒配管5により環状に接続して構成され、前記減圧装置の弁開度を調整できるヒートポンプサイクルと、給湯用の液体を蓄える貯湯槽6と、前記貯湯槽内の液体が前記給湯装置を介し循環できる液体配管8と、前記液体配管に貯湯槽内の液体を流通させるポンプ7と、前記給湯用熱交換器の入水温度を検出する入水温度検出手段31と、外気温度を検出する外気温度検出手段32と、前記入水温度検出手段または前記外気温度検出手段により前記第一及び第二の減圧装置を制御する制御手段であるマイクロコンピュータ30を備えている。
第2の実施の形態において、上記第1の実施の形態におけるヒートポンプ式給湯装置の冷媒として二酸化炭素を使用した場合について説明する。
、前記中間熱交換器が蒸発器として作用したまま入水温度が、17℃から50℃に上昇した場合、超臨界サイクルを形成する二酸化炭素の等温線に基づき、非常に高い圧力での運転が強いられ、低入水温度に比べて成績係数の低い運転となる。
