Abstract
【解決手段】蒸気圧縮式冷凍サイクルを行う冷媒回路(20)と、吸着剤を有する吸着ロータ(31)とを備えている。冷媒回路(20)には、室内熱交換器(23)で放熱した冷媒の余熱によって吸着ロータ(31)の再生用空気を予熱する予熱熱交換器(33)と、この予熱された再生用空気を圧縮機(21)の吐出冷媒で加熱する加熱熱交換器(32)とが設けられている。よって、吸着ロータ(31)へ流れる再生用空気が十分に加熱されるので、吸着剤の再生能力が向上する。
【選択図】図1
Description
本発明の参考形態1について説明する。本参考形態の空気調和装置(10)は、図1に示すように、冷媒回路(20)と吸着ロータ(31)を備えている。
次に、空気調和装置(10)の運転動作について説明する。この空気調和装置(10)は、暖房加湿運転と冷房運転とを切り換えて行う。
この暖房加湿運転は、図1に示すように、室内熱交換器(23)で加熱された空気aと、吸着ロータ(31)において再生動作により加湿された空気cとが室内へ供給される運転である。
この冷房運転は、図示しないが、室内熱交換器(23)で冷却された空気が室内へ供給される運転である。なお、この冷房運転において、吸着ロータ(31)、加熱熱交換器(32)および予熱熱交換器(33)は休止状態となる。
この参考形態1によれば、暖房加湿運転時に、吸着ロータ(31)へ送る再生用空気を予熱熱交換器(33)で一旦予熱し、さらに加熱熱交換器(32)で加熱するようにしたので、再生用空気の温度を十分に高くすることができる。これにより、吸着ロータ(31)の再生能力を向上させることができ、加湿能力を高めることができる。
本発明の参考形態2について説明する。本参考形態は、図2および図3に示すように、上記参考形態1における加熱熱交換器(32)および予熱熱交換器(33)には暖房加湿運転時にのみ冷媒が流れるようにしたものである。ここでは、上記参考形態1の空気調和装置(10)と異なる点について説明する。
本発明の実施形態1について図4および図5を参照しながら説明する。本実施形態は、上記参考形態1の冷媒回路(20)の構成を変更し、冷房除湿運転を行うようにしたものである。ここでは、上記参考形態1の空気調和装置(10)と異なる点について説明する。
本実施形態の暖房加湿運転は、図4に示すように、上記参考形態1と同様、室内熱交換器(23)で加熱された空気aと、吸着ロータ(31)において再生動作により加湿された空気cとが室内へ供給される運転である。
この冷房除湿運転は、図5に示すように、室内熱交換器(23)で冷却された空気aと、吸着ロータ(31)において吸着動作により除湿(減湿)された空気dとが室内へ供給される運転である。
本発明の実施形態2について図6〜図9を参照しながら説明する。本実施形態は、上記実施形態1における調湿機構(30)の構成を変更したものである。つまり、本実施形態では、上記実施形態1における吸着ロータ(31)および加熱熱交換器(32)を省略し、調湿機構(30)として吸着熱交換器(34,35)を設けるようにした。ここでは、上記実施形態1の空気調和装置(10)と異なる点について説明する。
本実施形態の暖房加湿運転は、図6および図7に示すように、第1運転と第2運転とが交互に行われ、室内熱交換器(23)で加熱された空気aと、吸着熱交換器(34,35)で再生動作により加湿された空気cとが室内へ供給される運転である。
本実施形態の冷房除湿運転は、図8および図9に示すように、第1運転と第2運転とが交互に行われ、室内熱交換器(23)で冷却された空気aと、吸着熱交換器(34,35)で吸着動作により除湿された空気dとが室内へ供給される運転である。
本発明の実施形態3について図10〜図13を参照しながら説明する。本実施形態は、上記実施形態2における電磁弁(48,49)を省略し、3つの四路切換弁(22,36,37)を備えるようにしたものである。ここでは、上記実施形態2の空気調和装置(10)と異なる点について説明する。
本実施形態の暖房加湿運転は、図10および図11に示すように、第1運転と第2運転とが交互に行われ、室内熱交換器(23)で加熱された空気aと、吸着熱交換器(34,35)で再生動作により加湿された空気cとが室内へ供給される運転である。
本実施形態の冷房除湿運転は、図12および図13に示すように、第1運転と第2運転とが交互に行われ、室内熱交換器(23)で冷却された空気aと、吸着熱交換器(34,35)で吸着動作により除湿された空気dとが室内へ供給される運転である。
