Abstract
調湿装置における新たな膨張弁の制御手段を提供する。
【解決手段】
圧縮機(53)と、吸着剤が担持された第1吸着熱交換器(51)と、開度調整自在な膨張弁(55)と、吸着剤が担持された第2吸着熱交換器(52)とを有する冷媒回路(50)を備えている。第2吸着熱交換器(52)で空気の水分を吸着し且つ第1吸着熱交換器(51)で空気に水分を放出する第1バッチ運転と、第1吸着熱交換器(51)で空気の水分を吸着し且つ第2吸着熱交換器(52)で空気に水分を放出する第2バッチ運転とを交互に行い、調湿空気を室内に供給する。更に、膨張弁(55)の開度に制御する一方、第1バッチ運転の開始時には膨張弁(55)を前回の第1バッチ運転の終了時の膨張弁(55)の開度に設定し、第2バッチ運転の開始時には膨張弁(55)を前回の第2バッチ運転の終了時の膨張弁(55)の開度に設定する。
【選択図】 1
Description
次に、本実施形態の調湿装置(10)の運転動作について説明する。具体的に、本実施形態の調湿装置(10)は、除湿運転と加湿運転とが行われる。
次に、上記調湿装置(10)における膨張弁(55)の開度制御について説明する。
以上のように、本実施形態によれば、各バッチ運転の開始から弁制御開始時が経過すると冷媒過熱度が所定値になるように膨張弁(55)の開度を制御するようにしたために、膨張弁(55)の開度を比較的に安定して制御することができる。つまり、各バッチ運転が短時間で切り換わるので、冷媒過熱度が各バッチ運転時において大きく変動する。そこで、各バッチ運転の終了近くにおいて、膨張弁(55)の開度を冷媒過熱度が所定値になるように制御するので、膨張弁(55)の開度の安定した制御を可能とすることができる。
本発明は、上記実施形態の冷媒回路(50)に限定されるものではなく、開度調整自在な膨張弁(55)を有する冷媒回路(50)を備えた調湿装置(10)であればよい。
