る。 That is, the amount of heating by the water heater 23 is determined by detecting the hot water outlet temperature with the temperature detector 27 and adjusting the opening degree of the heating control valve 17 with the controller 31 . Since the amount of heating can be determined almost centrally, control of the supplied hot water is extremely simplified, while the heating in the water heater 23 compensates only for the amount of heating that is insufficient on the low temperature generator side. This enables energy-saving operation.

9, the three-way valve 14 is closed by the controller 30, the operation of the first absorption liquid pump 7 is also stopped, and hot water is heated only by the water heater 23.

ことが好ましい。 In such cases, a bypass pipe 35 and an on-off valve 36 are installed to reduce heat loss in the absorber A and condenser C so that hot water can circulate inside the absorption chiller/heater. If this is not possible, it is preferable to allow the hot water in the water pipe 21 to bypass the absorber A and the condenser C and flow into the water heater 23.

When opened, the pressure on the condenser C side is reduced to approximately the same as that on the absorber A side, so refrigerant can be generated from the low temperature heat source generator G S absorption liquid at a lower temperature, and there is no communication pipe 37. You can get more heat compared to when.

Absorption liquid pipe leading to the generator, absorption liquid pipe leading from the high temperature generator to the low temperature generator, absorption liquid pipe leading from the high temperature generator to the low temperature generator, refrigerant pipe leading from the high temperature generator to the condenser via the low temperature generator, and Closes the on-off valve of the water pipe on the outlet side of the cooler provided in the condenser, and the on-off valve of the bypass pipe that branches from the water pipe and connects to the hot water load via the water heater, and the refrigerant bypass pipe that leads from the evaporator to the absorber. When hot water is supplied, the refrigerant and absorption liquid are circulated in the absorber and evaporator, which are independent from the refrigerant circulation cycle between the high temperature generator and the water heater. A water heater can further raise the temperature and supply hot water stably to the hot water load, and as a system that combines an absorption chiller/heater with a solar water heater, which is a low-temperature heat source, it is possible to obtain solar water with a sufficient amount of heat. It can be used like a heat exchanger, and when the amount of heat from solar hot water is insufficient, the function of an auxiliary boiler can be given to the absorption chiller/heater, and when cooling is required, such as in the summer, the above-mentioned on-off valve can be switched on and off, and solar hot water can be heated. The function of a water chiller using water can be given to an absorption chiller/heater, which eliminates the need for a heat exchanger or hot water tank between solar hot water for heating and hot water for heating, and simplifies the piping system. We can provide an absorption chiller/heater that makes maximum use of solar heat and can provide a stable supply of cold and hot water.

を開くことを特徴とする吸収冷温水機。1. In an absorption chiller/heater equipped with a hot water circuit consisting of a generator, a condenser, an evaporator, and an absorber, and supplying the heat obtained in the absorber and condenser to a hot water load, the generator is heated by a low heat source fluid. It consists of a low-temperature heat source generator that uses a heat source as a heat source, and a high-temperature generator that uses a high-temperature heat source as the heat source of the heater. It constitutes a circulation cycle of refrigerant and absorption liquid for supplying cold water from a container to a cold water load, and supplying hot water to a hot water load via an absorber, a condenser, and a water heater, and also from a low-temperature heat source generator to a high-temperature generator. Absorption liquid pipe leading to the high temperature generator, absorption liquid pipe leading to the low temperature generator, refrigerant pipe leading from the high temperature generator to the condenser via the low temperature generator, water pipe on the outlet side of the cooler installed in the condenser, this On-off valves are provided in the bypass pipe that branches from the water pipe and reaches the hot water load via the water heater, and the refrigerant bypass pipe that runs from the evaporator to the absorber, and when hot water is supplied, the absorption liquid pipe that runs from the low-temperature heat source generator to the high-temperature generator, Close the on-off valves of the absorption liquid pipe from the high temperature generator to the low temperature generator, the refrigerant pipe from the high temperature generator to the condenser via the low temperature generator, and the water pipe on the outlet side of the cooler provided in the condenser, and An absorption chiller/heater characterized by opening the on-off valves of a bypass pipe that branches from a water pipe, passes through a water heater, and reaches a hot water load, and a refrigerant bypass pipe that runs from an evaporator to an absorber.
