  As described in Patent Document 2, the present inventor receives a first heat transfer system for transferring heat from a cold supply unit such as a compression heat pump to a hot supply unit, and driving heat from an absorption refrigerator, etc. We are developing a combined system that includes a second heat transfer system that transfers heat from the supply unit to the heat supply unit. Here, the first heat transfer system such as a compression heat pump requires electric power or power for driving. In addition, driving heat of a certain temperature or more needs to be supplied to drive the second heat transfer system such as an absorption refrigerator, an absorption heat pump, and an adsorption refrigerator. For this reason, using a combined supply system (for example, a combination of a hybrid solar panel, windmill or watermill power and a solar heat collector, etc.) capable of supplying electric power or power and thermal energy to the combined system. Are considering.

  However, in the solar heat utilization system described in Patent Document 1, when the heat medium is not heated up to 80 degrees, it becomes difficult to drive the absorption refrigerator or the like (drive of the second heat transfer system). For example, when performing cooling operation of an absorption refrigeration machine or the like, in order to obtain cold water having a sufficiently low temperature, the heat medium temperature needs 60 degrees at a minimum, but there is a drawback that the capacity is significantly reduced. For this reason, the heat medium is not practically used for driving the absorption refrigeration machine or the like at about 75 degrees or less, and can be used for driving the absorption refrigeration machine or the like when a temperature higher than this cannot be obtained. It will disappear. Also, in the solar heat utilization system described in Patent Document 2, since the hot water temperature in the hot water storage tank decreases in the morning, it may be difficult to drive an absorption refrigerator or the like as described above. Furthermore, not only in cooling operation but also in heating operation, it becomes difficult to drive an absorption refrigerator or the like depending on the heat medium temperature.

  As described above, in the systems described in Patent Documents 1 and 2, it is difficult to cope with the fluctuation of the heat energy temperature called the heat medium temperature.

  The present invention has been made to solve such a problem, and the object of the present invention is to provide a combined supply system capable of generating and supplying electric power or power and thermal energy. An object of the present invention is to provide a combined system capable of executing control according to temperature fluctuation of supplied thermal energy.

The combined system of the present invention includes a co-feed system, a first heat transfer system, a second heat transfer system, and a selection control unit. The co-supply system supplies first energy composed of electricity or power and also supplies second energy that is thermal energy that fluctuates in temperature. The first heat transfer system is driven by receiving the supply of the first energy from the cogeneration system, and transfers heat from the cold heat supply unit to the hot heat supply unit. The second heat transfer system receives one or both of the second energy supplied from the cogeneration system and the heat of the heat supply unit of the first heat transfer system as drive heat, and receives the heat supply from the cold supply unit. Heat transfer to The selection control unit selects one of at least three operation modes for supplying the second energy from the cogeneration system to at least one of the first heat transfer system and the second heat transfer system according to the temperature of the second energy. Select automatically. Furthermore, at least three operation modes are set in each of the cooling operation and the heating operation, and at least three operation modes in the cooling operation and at least three operation modes in the heating operation are respectively set. The mode which receives the heat of the heat supply part of a 1st heat transfer system as drive heat is included.

  According to the present invention, it is possible to select an appropriate one from three or more operation modes according to the second energy temperature, and in the case of providing a combined supply system capable of supplying electric power or power and thermal energy, Control according to the temperature fluctuation of the supplied thermal energy can be executed.
