して暖房を行うことになる。 On the other hand, regarding the heat pump cycle, during heating using a water heat source, the refrigerant compressed by the compressor 23 becomes high pressure and high temperature and flows into the indoor heat exchanger 25 through the four-way valve 24. The refrigerant that has exchanged heat with the indoor air is condensed into a high-pressure liquid phase, and then flows into the heating expansion valve 26. Here, the refrigerant expands and becomes low pressure and low temperature, and the check valve 29 and the three-way valve 30
into the water-refrigerant heat exchanger 20 through. Here, the refrigerant heated by the water sent from the heat storage tank 14 evaporates into a low-pressure, low-temperature gas phase, enters the compressor 23 through the three-way valve 31 and the four-way valve 24,
Here, it is compressed to become a high-pressure, high-temperature refrigerant, and the cycle described above is repeated. This allows heating to be performed using water as a heat source.

を調整して水が凍結しないようにしている。 Furthermore, when heating is performed using a water heat source by flowing a refrigerant through the water-refrigerant heat exchanger 20, the water in the heat storage tank 4 passes through the pump 21 and enters the water-refrigerant heat exchanger 20, where it is cooled by the refrigerant and the temperature increases. As the temperature decreases, water returns to the heat storage tank 14 through the water temperature adjustment valve 22. The water temperature regulating valve 22 adjusts the flow rate so that the outlet temperature of the valve is always at a constant temperature of 0° C. or higher (for example, 5° C.) or higher to prevent the water from freezing.

気熱源による運転をするようにしている。 In addition, the inlet temperature of the pump 21 is detected by a thermistor (not shown), and is kept at a constant temperature (for example, 5°C).
In the following, the operation of the heat pump using the water-refrigerant heat exchanger 20 is stopped, and the three-way valves 30 and 31 are switched to pass the refrigerant to the outdoor air-refrigerant heat exchanger 32 so that operation is performed using an air heat source.
このように水−冷媒熱交換器２０を使つて暖房
運転している時は水が凍結しないようになつてい

−冷媒熱交換器の利用率も向上する。 In addition, as shown in FIG. 2, a water-refrigerant heat exchanger 20
is placed above the heat storage tank 14 and brought into thermal contact with the heat storage tank 14 via the air layer 33, and these are integrated and insulated from the outside air with the heat insulating material 18, so that water -
Even if the heating operation using the refrigerant heat exchanger 20 is stopped, the water in the water-refrigerant heat exchanger 20 is always kept in the heat storage tank 1.
The residual heat from Step 4 prevents it from freezing. Furthermore, the pump 21, connection piping 34, 3
5, 36, 37, like the water-refrigerant heat exchanger 20, the water temperature adjustment valve 22 is also brought into thermal contact with the tank 14 via the air layer 33, and can be insulated from the outside air to prevent these from freezing. Not only is this possible, but the drop in the inlet temperature of the pump 21 is also reduced.
The switching to the air heat source is accordingly reduced, and the utilization rate of the water-refrigerant heat exchanger is also improved.

を繰返す。 When performing cooling operation, the four-way valve 24 is switched to the cooling side, and the gaseous refrigerant, which has been compressed by the compressor 23 and has become high-pressure and high-temperature, passes through the four-way valve 24 and then through the three-way valve 31 to the outdoor air. - The refrigerant enters the heat exchanger 22, exchanges heat with air, condenses, becomes a high-pressure liquid phase, expands to a low pressure through the expansion valve 27, and expands to a low pressure through the check valve 28.
and enters the indoor heat exchanger 25. Here, the refrigerant heated by the indoor air evaporates into a low-pressure gas phase and enters the compressor 23 through the four-way valve 24, where it is compressed to become a high-pressure, high-temperature refrigerant, and the above cycle is repeated.
また本考案によれば水の熱源は太陽であるが、
これが他の熱源、例えば排熱等であつても本考案
が適用できることは言うまでもない。 Also, according to this invention, the heat source of water is the sun,
It goes without saying that the present invention can be applied even if the heat source is another heat source, such as exhaust heat.

し得るという効果を有するものである。 As described above, according to the present invention, the water-refrigerant heat exchanger is located above the heat storage tank, is in thermal contact with the air layer, and is integrated with the outside air through the insulation material. Because it is insulated, the water-refrigerant heat exchanger does not freeze, which not only improves the reliability of the water-refrigerant heat exchanger, but also reduces the pump inlet temperature and reduces the water-refrigerant heat exchanger. This has the effect of improving the utilization rate of the exchanger and making more effective use of energy and resources.
