る。In the absorption-type cold / hot water simultaneous supply type heat pump of the first structure, since a plurality of neutral salts are added and the crystallization limit temperature can be increased more than that of the lithium bromide aqueous solution, it can be kept under atmospheric pressure. It is possible to perform the operation in which the absorption liquid is kept at a high concentration, and therefore the heat transfer area can be reduced and the device can be downsized. Also, the temperature and pressure inside the condenser are
Since the heat source fluid does not rise as much as the conventional absorption heat pump that exchanges heat in the order of the absorber and the condenser, it is possible to reduce the regeneration pressure and increase the concentration of the absorbing liquid. That is, it is possible to sufficiently increase the concentration of the absorbing solution by operating under atmospheric pressure, and it is also possible to perform high-concentration operation in which the crystallization limit temperature is increased by adding a plurality of neutral salts compared to the case of the lithium bromide aqueous solution. Therefore, the miniaturized device can be further miniaturized.

This absorption-type cold / hot water simultaneous supply heat pump has the conventional structure shown in FIG. Although it has almost the same structure as the double-effect absorption heat pump, it flows through the cooling water pipe 17 and radiates heat by work against a heating load or hot water supply load (hereinafter referred to as a heating load, etc.) not shown, and the temperature drops to, for example, 40 ° C. The warm heat source fluid for heating, which has recirculated, for example, warm water, flows in the order of the condenser 4 and the absorber 7 to cool the inside of the condenser, and the temperature of the warm water itself is increased. Instead of using a conventional simple aqueous solution of lithium bromide, a neutral salt capable of increasing the crystallization limit temperature, such as lithium iodide, lithium chloride, or lithium nitrate, is added to 100 parts of lithium bromide. 5,4
It is configured to use an aqueous solution added at a ratio of 1 to 25 (molar ratio).

The crystallization limit line a in the double-effect absorption-type cold / hot water simultaneous supply type heat pump according to the embodiment of the present invention is, for example, a cooling heat source fluid for cooling, which has been heated to 12 ° C. and recirculated to the evaporator 5, for example, 7 ° C. While cooling to 40 ° C. and supplying it to the cooling load (not shown) from the cold water pipe 16, the temperature drops to 40 ° C. and the condenser 4
When comparing the operation of heating the warm water refluxed to the absorber 7 to 45 ° C. and supplying it from the cooling water pipe 17 to a heating load (not shown), etc., an aqueous lithium bromide solution is used for the absorbing liquid shown by the broken line in FIG. The crystallization limit line b of the conventional double-effect absorption heat pump is relaxed by about 10 ° C. as shown in FIG. 2, and the concentration of the concentrated solution and the crystallization limit line a (crystallization limit concentration) are It can be seen that the difference increases and that the present invention is more difficult to crystallize than the prior art.

The double-effect absorption cold / hot water simultaneous supply type heat pump of the present invention indicated by the solid line with the symbol A has a lower regeneration pressure than the conventional double-effect absorption heat pump indicated by the dashed line with the symbol B. It can be seen that the concentration is increased. Therefore, in the absorption-type cold / hot-water simultaneous supply heat pump of the present invention, the heat transfer area can be reduced, or the absorption liquid concentration can be sufficiently increased under atmospheric pressure.

ートポンプである。(Second Embodiment) A second embodiment of the present invention will be described with reference to FIG.
The absorption type cold / hot water simultaneous supply heat pump of the second embodiment uses the same solution as that of the first embodiment as the absorption liquid, and flows through the cooling water pipe 17 to cause a heating load (not shown). For example, about half of the warm heat source fluid for heating, which has recirculated after being cooled to 40 ° C., for example, warm water flows to the absorber 7 to bypass the condenser 4 and the remaining half is absorbed. It is a double-effect absorption cold / hot water simultaneous supply heat pump configured to bypass the vessel 7 and flow to the condenser 4.

低下する。Normally, the cold heat consumed for condensing the refrigerant vapor in the condenser 4 is less than half the amount of heat generated when the refrigerant is absorbed in the absorbing liquid in the absorber 7, and therefore, as described above. In the case of the conventional double-effect absorption heat pump in which the entire amount of warm water is made to flow in the order of the absorber 7 and the condenser 4 by flowing approximately half of the warm water that has cooled to 40 ° C and has recirculated to the condenser 4. As a result, the temperature and pressure inside the condenser 4 decrease.

Therefore, it is possible to reduce the heat transfer area and sufficiently increase the concentration of the absorbing solution under atmospheric pressure. Therefore, also in this case, the device can be made smaller than the conventional absorption heat pump.

It is possible to supply the heat source fluid from the condenser at the same time, and about half of the heat source fluid exchanges heat with the absorber to bypass the condenser, and the remaining half of the heat exchange with the condenser to exchange the absorber. Also in the absorption-type cold / hot water simultaneous supply heat pump of the second configuration provided so as to bypass and circulate, the condenser vapor is generally condensed from the calorific value generated when the refrigerant is absorbed by the absorber in the absorber. Since the amount of heat required for this is smaller, the temperature and pressure in the condenser do not rise as much as the conventional absorption heat pump that flows by exchanging the entire amount of the heat source fluid in the order of the absorber and the condenser. Since the regeneration pressure can be lowered and the concentration can be increased, the device can be downsized also in this case for the same reason as the absorption-type cold / hot water simultaneous supply heat pump of the first configuration.
