かつた。 Conventionally, in this type of multi-source heat pump device, the air heat source coil is generally installed horizontally or slightly inclined, and air is taken in by a fan from the intake port on the side of the multi-source heat pump device, and exhausted from the exhaust port on the top. The structure was such that However, since the suction and exhaust ports are open, when the water heat source of the multi-heat source heat pump device is operated alone, refrigerant flows inside the air heat source coil, resulting in a large amount of heat loss due to the suction and exhaust ports. could not be avoided.

The exhaust port is closed when the fan is stopped, and is opened when the fan is in operation, in order to reduce heat loss from the air heat source coil.

る冷暖房用配管である。 Hereinafter, this invention will be explained with reference to specific embodiments with reference to the drawings. In the figure, 1 is a compressor, one end of a water coil 2 is connected to the compressor 1 via a four-way valve 3, the other end is connected to an air heat source coil 5 via an expansion valve 4, and a water heat source coil 6. The other end of the water heat source coil 6 is connected to the compressor 1 via the four-way valve 3. In this way, the compressor 1, four-way valve 3, water coil 2, expansion valve 4, air heat source coil 5, and water heat source coil 6 are connected in series to form a so-called closed circuit, and the whole is housed in the case 7. It has a basic configuration, and during heating, the refrigerant circulates through the above-mentioned closed circuit as shown by the solid line, and during cooling, it circulates as shown by the broken line. Further, 8 is a water heat source water pipe for supplying a heat source such as hot water to the water heat source coil 6, and 9 is a water coil 2, which is an air conditioning pipe that is heated and cooled.

設置されている。 Next, an intake port 10 is provided on the side of the case 7 of the multi-source heat pump device, and a louver 11 is attached to the intake port. In addition, an exhaust port 1 is located at the top of the case almost directly above the air heat source coil 5.
2, and a louver 13 which can be opened and closed and which normally closes under its own weight is attached. Further, a fan 14 is installed directly below the air heat source coil 5 to take in air from the intake port 10 and exhaust it from the exhaust port 12.
次に以上のような構成の本考案装置の動作につ
いて説明する。 Next, the operation of the device of the present invention having the above configuration will be explained.
例えば暖房時においては、太陽熱や排熱などに

そしてこの温水により水熱源コイル６において、

コイル２で凝縮して暖房用の熱を冷房用配管９に
与える。この時上述したフアン１４は停止してい
るため排気口１２のルーバ１３は閉じられてい
る。 For example, during heating, if the temperature of the heat source hot water is higher than the outside temperature due to heating by solar heat or waste heat, this heat source hot water is heated by the water heat source water piping 8.
is supplied to the multi-source heat pump device.
Then, this hot water causes the water heat source coil 6 to
The refrigerant evaporates, that is, absorbs heat, becomes high pressure in the compressor 1, is condensed in the water coil 2, and provides heat for heating to the cooling piping 9. At this time, since the fan 14 described above is stopped, the louver 13 of the exhaust port 12 is closed.
なお、膨張弁４を通過した後の冷媒の状態は、
空気熱源コイル５と水熱源コイル６の双方の温度

イル５では排熱が行なわれ、ルーバ１３が閉じら
れていれば熱損失が少なくなる。 The state of the refrigerant after passing through the expansion valve 4 is as follows:
It is determined by the temperatures of both the air heat source coil 5 and the water heat source coil 6. That is, since the pressure within the coils 5 and 6 is approximately constant, the higher temperature coil evaporates more and absorbs heat. For example, if the hot water temperature is 15℃ and the outside temperature is -5℃, both coils 5,
The temperature of the refrigerant in the refrigerant 6 is, for example, 0° C. In this case, the water heat source coil 6 absorbs heat, the air heat source coil 5 exhausts heat, and if the louver 13 is closed, heat loss will be reduced.
供給される熱源温水の温度が外気温より低くな
ると、多熱源ヒートポンプ装置は外気による吸熱
運転に切替わる。この時フアン１４の運転が開始
され、閉鎖されていたルーバ１３が前記フアン１
４の風圧に寄つて開放されて通風が行なわれ、空
気熱源コイル５により外気と冷媒との間で熱交換
がなされる。 When the temperature of the supplied heat source hot water becomes lower than the outside air temperature, the multi-heat source heat pump device switches to heat absorption operation using outside air. At this time, the operation of the fan 14 is started, and the louver 13, which had been closed, is opened to the fan 1.
The air heat source coil 5 is opened to allow ventilation, and the air heat source coil 5 exchanges heat between the outside air and the refrigerant.

気の流通まで防止され、熱的損失が抑制される。 The air heat source coil 5 exchanges heat between the outside air and the refrigerant. On the other hand, in cooling operation, when the air heat source coil 5 is used, that is, when heat exchange is performed using outside air, the fan 14 is operated to apply wind pressure to the louver 1.
3 is opened and outside air is applied to the air heat source coil 5 to promote heat exchange and exhaust heat from the refrigerant. Furthermore, when exhausting heat by flowing water from the water heat source water piping 8 to the water heat source coil 6, the refrigerant that has become high pressure by the compressor 1 is condensed in the water heat source coil 6, exhausts heat, and becomes low temperature. The water passes through the water coil 2, evaporates, absorbs heat from the cooling/heating piping 9, and performs a cooling effect. At this time, the refrigerant in the water heat source coil 6 is at a low temperature, and the fan 14 is stopped to prevent outside air from circulating in order to prevent the refrigerant from increasing in temperature due to heat exchange in the air heat source coil 5 and causing loss. do it like this. At this time, the louver 13 is closed by its own weight and closes the exhaust port 12, so that air circulation due to convection or the like is prevented, and thermal loss is suppressed.
ここで、これまでの説明をさらに定性的、概念
的に述べる。 Here, the explanation so far will be further explained qualitatively and conceptually.
暖房時は、圧縮機１から吐出された高温高圧の
ガス状の冷媒は、水コイル２で熱交換され、水を
加熱して暖房に供する。これにより冷媒は熱エネ
ルギーを放出し、凝縮し高圧の液冷媒となる。 During heating, the high-temperature, high-pressure gaseous refrigerant discharged from the compressor 1 undergoes heat exchange in the water coil 2 to heat water and provide heating. This causes the refrigerant to release thermal energy and condense into a high-pressure liquid refrigerant.
この液冷媒は膨張弁４を通り減圧され、ガスが
一部混在した低圧の液となる。 This liquid refrigerant passes through the expansion valve 4 and is depressurized to become a low-pressure liquid partially mixed with gas.
さて低圧側の状態は空気熱源コイル５と水熱源
コイル６が同じ圧力状態である、つまり同じ温度
で冷媒が空気または熱源水からの熱を吸収し、蒸
発する。具体例として、空気温度が−５℃、熱源
水温が10℃であれば、高温熱源を利用するため、
空気熱源コイル用のフアン１３は停止し、シヤツ
ターも閉じており、低圧部の温度は例えば５℃程
度の温度でほぼ一定しており、この状態で冷媒は
蒸発していく。これは熱源水からの吸熱を行うた
めである。 Now, on the low pressure side, the air heat source coil 5 and the water heat source coil 6 are in the same pressure state, that is, the refrigerant absorbs heat from the air or the heat source water and evaporates at the same temperature. As a specific example, if the air temperature is -5℃ and the heat source water temperature is 10℃, in order to use a high temperature heat source,
The fan 13 for the air heat source coil is stopped, the shutter is closed, and the temperature of the low-pressure part is approximately constant at, for example, 5° C., and the refrigerant evaporates in this state. This is to absorb heat from the heat source water.
このため仮に外気が流入してくると、冷凍サイ
クル系内の熱が外気に熱損損失として失われるこ
とになる。何故ならば、空気熱源コイル５内も５
℃であり、外気は−５℃であり、外気は−５℃で
あるからである。 Therefore, if outside air were to flow in, the heat within the refrigeration cycle system would be lost to the outside air as heat loss. This is because the inside of the air heat source coil 5 is also
This is because the outside air is -5°C and the outside air is -5°C.
以上のように、この考案は上述した構成のヒー

化する場合においてもコスト的に有利である。 As described above, this invention is based on the heat pump device having the above-mentioned configuration, with the exhaust port on the top of the case being
In normal conditions, the looper closes under its own weight, and when the fan rotates, it opens and closes. By adopting a structure that can be freely opened and closed, the above-mentioned louver closes when the water heat source is operated alone, and as a result, heat loss from the air heat source coil is suppressed. This has the effect of providing a highly efficient multi-source heat pump device. This is also advantageous in terms of cost when modifying a conventional air source heat pump to create a multi-heat source heat pump.
