【考案の詳細な説明】
この考案は暖房などに用いるヒートポンプ装置の構成に
関するものである。[Detailed Description of the Invention] This invention relates to the configuration of a heat pump device used for heating and the like.
従来のこの種のヒートポンプ装置では蒸発器として空気
熱源用コイルのみを有するものが多い。Many conventional heat pump devices of this type have only an air heat source coil as an evaporator.
この場合、熱源となる外気の温度によって暖房能力、成
績係数が変動し、特に外気温度が低いときに性能が著し
く低下する。In this case, the heating capacity and coefficient of performance vary depending on the temperature of the outside air, which is the heat source, and the performance deteriorates particularly when the outside air temperature is low.
従って、早朝時には外気が低温で、しかも暖房負荷が大
きいことを考慮すると、設備容量が過大となることが多
かった。Therefore, considering the fact that the outside air is low in the early morning and the heating load is large, the installed capacity is often excessive.
このため、外気低温時には熱源として空気ではなく、太
陽熱や各種の排温を利用して加熱して得た温水を熱源と
するための水熱源用コイルをも有する多熱源ヒートポン
プ装置が考られている。For this reason, multi-source heat pump devices are being considered that also have a water heat source coil that uses solar heat or various types of waste heat to heat hot water instead of using air as a heat source when the outside temperature is low. .
この構成では通常、上記温水は蓄熱槽に蓄えておいて使
用するのであるが、この蓄熱温度が水熱源として利用で
きる十分な温度である場合は外気を熱源とする空気熱源
用コイルのファンは停止させ、水熱源のみで運転させる
。In this configuration, the above-mentioned hot water is normally stored in a heat storage tank and used, but if this heat storage temperature is high enough to be used as a water heat source, the fan of the air heat source coil, which uses outside air as a heat source, stops. and operate only on water heat source.
次に、蓄熱温度が低下し、水熱源のみで不充分なときは
水熱源と空気熱源とを併用する。Next, when the heat storage temperature drops and the water heat source alone is insufficient, a water heat source and an air heat source are used in combination.
更に、蓄熱温度が低下すれば空気熱源のみで運転させる
。Furthermore, if the heat storage temperature decreases, the system will be operated using only the air heat source.
ところが、空気熱源のみで運転させる際にもヒートポン
プの低温冷媒が水熱源用コイルにも流れる管路接続の場
合には、このコイルをつつむ水が凍結し、その結果コイ
ルを破壊させる可能性がある。However, even when operating only with an air heat source, if the heat pump's low-temperature refrigerant is connected to a pipe that also flows to the water heat source coil, the water surrounding this coil may freeze, potentially causing the coil to break. .
この考案は以上のような点に鑑みてなされたもので、水
熱源が使用できない場合には、水熱源用コイルを蒸発器
としてではなく凝縮器として作用させることによって、
水熱源用コイルを囲む水の凍結を防止できるヒートポン
プ装置を提供することを目的としている。This idea was made in view of the above points, and when a water heat source cannot be used, by making the water heat source coil act as a condenser instead of an evaporator,
It is an object of the present invention to provide a heat pump device that can prevent water surrounding a water heat source coil from freezing.
