題があった。Conventionally, in such a single-duplex combination type absorption chiller-heater, an absorption chiller-heater which takes out hot water by using low-temperature water for engine jacket cooling which heats the low-temperature water regenerator as a heat source is disclosed in, for example, JP As already known from Japanese Patent Laid-Open No. 59-63311, this is an absorption chiller-heater which takes out hot water for heating from an absorber, and an absorption chiller-heater of a system which takes out hot water from such an absorber. Then, there were the following problems with the absorption-type chiller-heater that takes out hot water from the evaporator.

配水管をバルブ等で切り換る必要があった。That is, in the above-mentioned conventional absorption type chiller-heater, the cooling water flows through the absorber during the cooling operation, so that the heat transfer tube of the absorber is contaminated. When switching from cooling to heating, it is necessary to clean the heat transfer tube of the absorber. Also, the absorber allows cooling water to flow during cooling and warm water during heating, which complicates the piping on the equipment side, and requires switching the water distribution pipe on the equipment side with valves etc. during cooling and heating. was there.

った。[0006] An absorption chiller-heater which takes out hot water for heating from an evaporator is conceivable, as opposed to an absorption chiller-heater which takes out hot water for heating from an absorber, which is the conventional technique. It is important to take out the heat effectively by using the low temperature water for cooling the engine jacket that heats the regenerator as a heat source. However, conventionally, there is an upper limit to the temperature of the hot water for taking out the low temperature water for cooling the engine jacket as a heat source (for example, 45 ° C.), and there is a problem that the low temperature water for cooling the engine jacket cannot be effectively used as the heat source.

へ送ることができないことによる。That is, in the absorption chiller-heater according to the prior art, as shown in FIG. 6, the refrigerant vapor generated in the low-temperature water regenerator 13 which uses the engine jacket cooling low-temperature water 18 as a heat source is evaporated to take out hot water. In order to supply the low-temperature water regenerator 13 to the reactor 1, the pressure of the low-temperature water regenerator 13 needs to be higher than the pressure of the evaporator 1 in consideration of the flow path resistance of steam. However, in order to raise the temperature of the hot water taken out by the evaporator 1 (for example, 55 ° C.), it is necessary to maintain the saturation temperature of the refrigerant vapor in the evaporator 1 at a required temperature (for example, 58 ° C.) or higher. By the way, since the inside of the evaporator 1 has a saturated pressure of the above temperature (for example, 130 mmHgabs), the pressure inside the low temperature water regenerator 13 using the engine jacket cooling low temperature water 18 as a heat source should be higher than the pressure inside the evaporator 1. Becomes difficult at the temperature of the cold water 18 for cooling the engine jacket. This means that the temperature of the solution in the low temperature water regenerator 13 is the temperature of the low temperature water 18 for cooling the engine jacket (for example, 8
5 ° C.), the pressure (eg, 60 mmHgabs) in the low temperature water regenerator 13 at the temperature of the solution in the low temperature water regenerator 13 (eg, 70 ° C.) is lower than the pressure in the evaporator 1, and The refrigerant vapor generated in 13 is the evaporator 1
