る。(C) Problems to be Solved by the Invention This type of absorption heat pump device is a double-effect absorption heat pump device [hereinafter referred to as a conventional absorption heat pump device that obtains hot water at a lower temperature level than the heat source fluid supplied to the high temperature generator. A heat pump device] (see Japanese Patent Application Laid-Open No. 52-71751 <Fig. 3> and Japanese Patent Application Laid-Open No. 58-31264) is used to increase the latent heat of condensation of the refrigerant in the condenser to raise the warm water.

低下を招くという問題点を有していた。On the other hand, the conventional absorption heat pump device of this kind described above uses the heat of the refrigerant separated from the absorption liquid in the high temperature generator for the concentration of the absorption liquid in the low temperature generator, thereby absorbing the refrigerant in the absorber by the utilization amount. Although the capacity can be increased, the refrigerant used for the concentration of the absorbing liquid is cooled in the condenser to lower the temperature and then heated in the evaporator to raise the temperature again, so the refrigerant is cooled in the condenser. This means that the heat in the device is wasted by that much, and there is a problem in that the operating efficiency is reduced due to the heat loss.

も運転効率〔成績係数〕が向上する。FIG. 2 is a Dühring diagram showing an absorption heat pump cycle by the circulation of the refrigerant and the absorption liquid in the above-described operation operation example. As can be seen from this Dühring diagram, in this device, the refrigerant liquid of about 16 ° C from the condenser (3) is added with the refrigerant liquid of about 55 ° C from the heater (23) to raise the temperature. Refrigerant liquid [By the way, its temperature is about 30 ℃. ] To the evaporator (4), the evaporator (4) is different from the conventional absorption heat pump device of this type in which only the refrigerant liquid of about 16 ° C. from the condenser (3) is sent to the evaporator (4). The heat required for raising the temperature of the refrigerant liquid sprinkled to the heat exchanger (25) to the boiling temperature [evaporation temperature of about 93 ° C] is small. In other words, this device is less in heat dissipation (heat loss) from the condenser (3) to the outside of the device than the conventional device. Further, in the present device, the operating efficiency (coefficient of performance) is improved as compared with the conventional device due to the small heat loss.

Since the cavitation is prevented by preventing the suction of bubbles of ( DR ), the amount of the refrigerant liquid sent to the evaporator (4) does not suddenly increase or decrease, and its temperature hardly changes. I don't. Therefore, in this device, the fluctuations of the internal temperature and the internal pressure of the evaporator (4) and the absorber (5) are kept small, and the temperature fluctuations of the high-temperature water obtained from the device to be heated (26) are also small. There are practical effects. In order to further reduce the temperature fluctuation of the high temperature water and stabilize the temperature of the acquired hot water, the liquid level relay (L DR ) pumps (P DR ) according to the liquid level in the refrigerant liquid reservoir (8). It is desirable to adjust the discharge speed of the pump (P DR ) by controlling the motor rotation speed of.

されると共にその冷媒液溜めの下流側に冷媒液用ポンプ
が配備されてなることを特徴とした二重効用型の吸収ヒ
ートポンプ装置。1. A high temperature generator, a low temperature generator, a condenser, an absorber and an evaporator are connected by piping to form a circulation path for a refrigerant and an absorbing liquid, and a cooling fluid is circulated through the condenser to form an evaporator. By supplying the heat source fluid to the high temperature generator and circulating the heated fluid to the absorber, the high temperature generator is operated at a lower pressure than the evaporator and the absorber, and the condenser and the low temperature generator are A double-effect absorption heat pump device configured to operate at a low pressure to raise the temperature of the fluid to be heated above the temperature of the heat source fluid by the heat generated when the absorbing liquid in the absorber absorbs the refrigerant, From the high-temperature generator to the evaporator via the heater of the low-temperature generator, and the downstream of the heater of this refrigerant flow path Side is equipped with a refrigerant reservoir and Medium liquid reservoir absorption heat pump apparatus of the double effect type, which is characterized in that the refrigerant liquid pump is deployed downstream of the.
