  In this case, even in the case of a low-temperature heat medium of about tens to 20 ° C. from the solar heat collecting panel 140, the heat medium temperature in the endothermic return path 127 is set to a temperature of about 50 ° C. by the heat pump 110. The heat medium cooled to about 10 ° C. or below 10 ° C. through the evaporator of the heat pump 110 is circulated inside the heat storage tank 150 through the tank internal circulation pipe 156. The heat medium inside the heat storage tank 150 can be cooled and returned to the solar heat collecting panel 140 via the heat exchange pipe 130.

  For this reason, even when the heating of the heat medium by the solar heat collecting panel 140 is low, hot water can be stored in the hot water supply tank 160 and the cooling medium can be stored in the heat storage tank 150 while reducing the load on the heat pump 110.

  In addition, as shown in FIG. 26, the solar thermal medium return path 142 of the solar heat collecting panel 140 is connected to the heat dissipation forward path 121 to the heat pump 110, the heat dissipation return path 122 from the heat pump 110 is connected to the heat exchange outward path 131, and the heat exchange return path 132. Is connected to the solar heat transfer path 141 to the solar heat collecting panel 140, the endothermic return path 127 from the heat pump 110 is connected to the hot water upper circulation second pipe 166 to the hot water tank 160, and the hot water upper circulation first pipe from the hot water tank 160 is connected. 165 may be connected to the endothermic path 126.

  In the above embodiment, the heat exchanging pipe 130 is buried in the ground to use the ground heat, but the heat exchanging pipe 130 is buried in a river or a lake and uses water heat. The hot water supply / cooling / heating system 100 using the heat pump 110 may be used.

  Furthermore, the heat exchange pipe 130 can be provided in a buried water tank such as a sewage or wastewater septic tank, and can use heat from domestic wastewater.

In the above embodiment, the heat exchange pipe 130 is described as one, but a plurality of heat exchange pipes 130 are provided to connect a plurality of sets of heat exchange circuit pipes 135 to the switching control panel 200. Each heat exchange circuit pipe 135 can be connected to and disconnected from the heat pump 110, the solar heat collecting panel 140, etc., and each heat exchange pipe 130 is buried in the ground, or the heat exchange pipe 130 is buried in the ground, rivers, lakes, and drains In some cases, they are buried underwater.

  In addition, when a plurality of heat exchange pipes 130 are provided, one heat exchange pipe 130 is provided in the ground or in water, and one heat exchange pipe is a multi-tube heat exchanger or plate type that transfers heat between liquids. A heat exchanger such as a heat exchanger is used to transfer heat from a high-temperature heat medium due to exhaust heat from a boiler or the like to a heat medium that has a slightly lower temperature, such as a high temperature or medium temperature, and then a heat storage tank via the switching control panel 200 It is also possible to send a heat medium to 150 and hot water supply tank 160.

  And in the said embodiment, although the two heat exchange pipes, the hot water supply circulation upper pipe 164 and the hot water supply circulation lower pipe 167, are arranged in the hot water supply tank 160 to warm the water in the hot water supply tank 160, It is also possible to warm the water in the hot water supply tank 160 by sending the heat medium from the switching control panel 200 to the hot water supply tank 160 as only one of the pipe 164 and the hot water supply circulation lower pipe 167.

  However, if the hot water supply circulation upper pipe 164 and the hot water supply circulation lower pipe 167 are provided, when the heat medium is heated to a high temperature of 90 ° C. or the like by the solar heat collecting panel 140, the heat medium is about 50 ° C. from the heat pump 110. Compared to the warming of water, it is warmed by a high temperature, so the warming of water by a high-temperature heat medium such as 90 ° C is warmed by a heat exchanger (heat exchange pipe) located in the lower part of the hot water tank 160 The heating of the water by the heat medium of about 50 ° C. is preferably performed by a heat exchanger (heat exchange pipe) disposed in the middle part of the hot water tank 160 or above the middle part.

  In the above embodiment, the heat exchanger arranged in the hot water supply tank 160 is a heat exchange pipe with the hot water supply circulation upper pipe 164 and the hot water supply circulation lower pipe 167, and the heat exchanger arranged in the heat storage tank 150 is the heat storage circulation. Although the heat exchange pipe with the pipe 159 is used, the heat exchanger is not limited to the pipe, and may be externally disposed on the hot water supply tank 160 or the heat storage tank 150 as plate type heat exchange.

  As described above, in the hot water supply / cooling / heating system 100 according to the present embodiment, the temperature of the heat medium sent to the evaporator 116 of the heat pump 110 by the heat radiation forward path 121 is set to a temperature of more than a dozen to 30 ° C., and the heat radiation return path 122 is passed through the evaporator 116. The heat transfer temperature of the heat pump 110 is increased by setting the temperature of the heat medium returning to about 10 ° C. or several tens of degrees C. and the temperature of the heat medium returning to the endothermic return path 127 via the condenser 118 to about 50 ° C. Wasteful energy consumption can be reduced.

  When the temperature of the heating medium can be raised to 60 ° C. or higher by the solar heat collecting panel 140, the hot water for living or heating can be efficiently stored by solar energy, and the heating by the solar collecting panel 140 Even if the temperature of the medium is a medium temperature of about 35 ° C. to 50 ° C. or a low temperature of 30 ° C. or less, the heat medium temperature of the endothermic return path 127 is raised to about 50 ° C. via the heat pump 110, or 50 ° C. or 60 ° C.

It can store the cooling medium and use solar energy effectively.

  In addition, although the said embodiment uses the ventilation air-conditioning machine 170, such as an air conditioner, and the heat radiation air-conditioning machine 180, such as a floor air-conditioning machine, as an air-conditioning machine, only the air-conditioning air-conditioning machine 170 or the heat radiation air-conditioning machine 180 is used as an air-conditioning machine. The hot water supply / cooling / heating system 100 may be connected to the switching control panel 200.
