Description

この発明はヒートポンプ式給湯機用熱交換ユニットのドレン排水装置に関するものである。   The present invention relates to a drain drainage device of a heat exchange unit for a heat pump type hot water heater.

従来のヒートポンプ式空気調和装置の熱交換ユニットにおいて、圧縮機を備えた機械室が下方に、熱交換を備えた熱交換室が上方にそれぞれ配置され、これらの両室が中間ベースにより仕切られており、ドレン排水装置として、機械室を構成する外装パネルには中間ベースのドレン排水孔からのドレン水を、パネル排水口を経て導く通水路が形成されている。
熱交換にて発生した凝縮水や、降雨等により機械室内に進入した雨水はドレン水となって中間ベースに留まる。ドレン水は塵埃等が混入されて汚水となり、中間ベースから中間ベース排水孔及びパネル排水孔を経て、外装パネルの通水路を流れ落ち排出される（例えば、特許文献１参照）。 In a heat exchange unit of a conventional heat pump type air conditioner, a machine room equipped with a compressor is arranged below, a heat exchange room equipped with heat exchange is arranged above, and both these rooms are partitioned by an intermediate base. As a drain drainage device, a water passage that guides drain water from the drain drain hole of the intermediate base through the panel drain port is formed in the exterior panel constituting the machine room.
Condensed water generated by heat exchange or rainwater that has entered the machine room due to rain or the like becomes drain water and remains on the intermediate base. Drain water is mixed with dust and becomes sewage, and flows down from the intermediate base through the intermediate base drain hole and the panel drain hole through the water passage of the exterior panel (see, for example, Patent Document 1).

Intrusion of dust and the like from

次に動作について図１、図６により説明する。
ヒートポンプ式給湯機において使用される冷媒は主に高温使用が可能なＣＯ2冷媒が使用され、冷媒回路内に封入されたＣＯ2冷媒は、電気品１２の制御にて運転される圧縮機１３にて圧縮され、空気用熱交換器１１内にて蒸発し、プロペラファン１４にて送風された外気と熱交換を行う。
空気用熱交換器１１による熱交換にて発生したドレン水２６、および、降雨等にて熱交換ユニット１内へ侵入した水は、中間ベース９からドレン排水装置のドレン排水部２４のドレン排水孔５より熱交換ユニット１外へ導かれ、中間ベース９の背面に凸設されたドレン排水部２４に係設させたドレンソケット１５に接続されたドレンホース１８にて熱交換ユニット１の外壁を伝わることなく外部へ排出される。 Next, the operation will be described with reference to FIGS.
The refrigerant used in the heat pump type hot water heater is mainly a CO 2 refrigerant that can be used at a high temperature, and the CO 2 refrigerant enclosed in the refrigerant circuit is supplied to the compressor 13 that is operated under the control of the electrical product 12. The air is then compressed, evaporated in the air heat exchanger 11, and exchanges heat with the outside air blown by the propeller fan 14.
The drain water 26 generated by heat exchange by the air heat exchanger 11 and the water that has entered the heat exchange unit 1 due to rain or the like are discharged from the intermediate base 9 into the drain drain hole 24 of the drain drain section 24 of the drain drain device. 5 is guided to the outside of the heat exchange unit 1, and is transmitted to the outer wall of the heat exchange unit 1 by a drain hose 18 connected to a drain socket 15 provided in a drain drainage 24 projecting from the back surface of the intermediate base 9. Without being discharged outside.

また、従来のように、熱交換にて発生したドレン水２６等が、ドレン水となって中間ベース９に留り、氷結して空気用熱交換器１１に不具合を生じさせるのを防ぎ、また、温水用熱交換器１０部に侵入して氷結して温水用熱交換器１０に不具合を生じさせるのを防ぎ、また、中間ベース９の腐食を防ぐことができる。 As described above, since the drainage device is provided with a drain drainage portion that protrudes on the back surface or side surface of the intermediate base below the same plane as the bottom surface of the intermediate base and has drainage holes on the bottom surface, Since the drain water is discharged directly from the drain drain hole 5 to the outside without passing through the water passage formed on the outer wall or the like of the heat exchange unit 1, it is possible to prevent the appearance of the heat exchange unit 1 from being damaged by the drain water. Can do.
Moreover, workability | operativity can be improved by making the drain drainage part 24 into an integral structure with the intermediate | middle base 9. FIG.
In addition, the drain water 26 and the like generated by heat exchange as in the prior art is prevented from remaining as drain water in the intermediate base 9 and freezing to cause a problem in the air heat exchanger 11. The hot water heat exchanger 10 can be prevented from entering and freezing to cause problems in the hot water heat exchanger 10, and corrosion of the intermediate base 9 can be prevented.

また、ドレン排水部２４の下部を覆う接続口部１５ａを有し、着脱可能にドレン排水部２４の下部に係設されたドレンソケット１５と、このドレンソケット１５の下部の接続口１５ｂに接続され外部に延出されたドレンホース１８とを備えたので、ドレン水により熱交換ユニット１の外観を損なうのを防ぐことができる。
また、ドレン排水部２４とドレンソケット１５を覆う着脱可能なカバー１９を備えたので、ドレン排水部２４、ドレン排水孔５、ドレンソケット１５への外部からの塵埃等の侵入を防止することができる。 In addition, it has a connection port portion 15 a that covers the lower portion of the drain drainage portion 24, and is connected to a drain socket 15 that is detachably attached to the lower portion of the drain drainage portion 24 and a connection port 15 b that is lower of the drain socket 15. Since the drain hose 18 extended to the outside is provided, it is possible to prevent the appearance of the heat exchange unit 1 from being damaged by the drain water.
Moreover, since the detachable cover 19 that covers the drain drainage portion 24 and the drain socket 15 is provided, it is possible to prevent dust and the like from entering the drain drainage portion 24, the drain drainage hole 5, and the drain socket 15 from the outside. .
