する熱損失が多いという欠点が免れなかつた。 Conventionally, in this type of multi-heat source heat pump device, the air heat source coil is generally installed horizontally or slightly inclined. For this reason, the structure of the fan was such that air was taken in through an intake port on the side of the multi-heat source heat pump device, and exhaust air was blown out from an exhaust port at the top. However, in a multi-heat source heat pump device with such a structure, when the water heat source is operated alone, warmed refrigerant flows in the air heat source coil, which is caused by the open intake and exhaust ports mentioned above. The disadvantage was that there was a lot of heat loss.

少させることを目的としている。 This idea was made in order to eliminate the above-mentioned drawbacks of the conventional method.The air heat source coil is placed vertically, is opened only by the wind pressure of the fan, and is equipped with a louver that normally closes the intake and exhaust ports. When the fan is stopped, these intake and exhaust ports are closed, and when the fan is in operation, these intake and exhaust ports are opened, and the purpose is to reduce heat loss from the air heat source coil.

In the figure, 1 is a compressor, 2 is a water coil, one end of piping is connected to the compressor 1 via a four-way valve 3, and the other end is connected to an air heat source coil 5 vertically placed via an expansion valve 4. is connected to.
Further, the air heat source coil 5 is connected to a water heat source coil 6, and the other end of this water heat source coil 6 is connected to the four-way valve 3.
It is connected to the compressor 1 through. 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 closed circuit as shown by the solid 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 heat source water pipe for supplying a heat source such as hot water to the water heat source coil 6.
This is heating piping that gets heated even more.

2 is installed. Further, between the intake port 10 and the exhaust port 11, an air heat source coil 5 is provided on the intake port side.
A fan 13 is installed to take in air from the intake port 10 and exhaust it from the exhaust port 11, and a ventilation path formed here is partitioned by a partition wall 14.
次に、以上のような構成の本考案に係る多熱源
ヒートポンプ装置の動作について説明する。 Next, the operation of the multi-source heat pump device according to the present invention having the above configuration will be explained.

され、所定個所へ送られて暖房に供される。 During heating operation, if the temperature of the heat source hot water is higher than the outside air temperature due to solar heat, waste heat, etc., this heat source hot water is supplied to the multi-heat source heat pump device through the water heat source water pipe 8. Then, the refrigerant of the multi-heat source heat pump device evaporates, that is, absorbs heat, in the water heat source coil 6 using the heat source hot water. Next, the evaporated refrigerant is sent to the compressor 1 via the four-way valve 3, compressed by the compressor 1, and radiated heat by the water coil 2. As a result, the water in the heating pipe 9 is heated by the water coil 2 and sent to a predetermined location for heating.

熱即ち損失となる。 The refrigerant that has radiated heat in the water coil 2 returns to the water heat source coil 6 via the expansion valve 4 and the air heat source coil 5, where it absorbs heat and evaporates again, and the above-described operation is repeated. In this way, when the temperature of the heat source hot water is higher than the outside air temperature, the air heat source coil 5 is not operated.
Therefore, the fan 13 is also stopped. Therefore, the louvers 12 of the intake and exhaust ports 10 and 11, which are opened by the wind pressure from the fan 13, remain closed, thereby preventing heat loss from the air heat source coil 5. In other words, the state of the refrigerant after passing through the expansion valve 4 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 air heat source coil 5 and the water heat source coil 6 is approximately constant, the higher temperature coil evaporates and absorbs more heat. Therefore, for example, if the heat source hot water temperature is 15°C and the outside air is -5°C, both coils 5 and 6
The temperature of the refrigerant inside becomes 0° C., and in this case, heat is absorbed in the water heat source coil 6, but it becomes waste heat, that is, loss, in the air heat source coil 5.
しかしながら、このようなとき、前述したよう

こで冷媒の蒸発即ち吸熱が行なわれる。 Next, when the temperature of the heat source hot water becomes lower than the outside air temperature, the flow of water in the water heat source water piping 8 is prevented,
On the other hand, the fan 13 is operated and the air heat source coil 5 absorbs heat from the high temperature outside air.
That is, when the fan 13 starts operating, the louver 12 is opened by the wind pressure of the outside air flowing through the ventilation path 14, and the heat of the outside air is supplied to the air heat source coil 5, where the refrigerant evaporates, that is, absorbs heat.
ここで、これまでの説明につき、さらに定性
的、概念的説明を以下に述べる。 Here, a more qualitative and conceptual explanation will be given below regarding the explanation so far.
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、凝縮した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 become a condensed, 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

ターも閉じており、低圧部の温度は例えば５℃程

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
℃, and the outside air is -5℃.

効果がある。 As described above, in the heat pump device having the above-mentioned configuration, the present invention has a structure in which the air heat source coil is placed vertically and the intake and exhaust ports on the side of the case can be opened and closed by a fan, thereby allowing independent operation of the water heat source. Sometimes the above-mentioned louvers are closed, which has the effect of suppressing heat loss from the air heat source coil and providing a highly efficient multi-source heat pump device.
