摘要： PROBLEM TO BE SOLVED: To reduce power consumption at a chiller during heat accumulation by providing a pipe through which outlet gas from a compressor is partly sent to a preheater for heating a solution in a concentrator/dilutor and is returned to an air heat exchanger. SOLUTION: In order to utilize heat which has been wasted to the external air through an air heat exchanger 2, outlet gas from a compressor 1 is allowed to flow into a preheater 26 by varying valve change-over conditions while a chiller 28 is being kept in a heat radiation state. Valves 18, 19, 20 and 27 are fully opened, and a valve 21 is fully closed. By this method, heat absorbed from cold water by an evaporator 3 is transmitted to a solution 25 by the preheater 26 and then wasted to the external air through the air heat exchanger 2, whereby heat can be effectively utilized. Further, since the solution 25 is preheated with residual heat before heat accumulation, reduction in power consumption at the chiller 28 for replenishing the heat capacity content of the solution 25 at the time of heat accumulation becomes possible.

摘要： PURPOSE:To obtain an air-cooled generator for cold and hot heat without using a fron gas by utilizing the heat of solution of refrigerant, which is generated when an absorbent is converted into a supercritical liquid, as hot heat and utilizing heat generated by the release of the refrigerant from the absorbent when the absorbent is converted into a non-supercritical liquid and/or the latent heat of vaporization of the absorbent as cold heat. CONSTITUTION:Refrigerant and an absorbent, which are little compatible with each other and are separated from each other in the interior of a low-pressure reactor 2, are introduced into a high-pressure reactor 1 by a unit 3 for sending gas under pressure and a unit 5 for sending liquid under pressure. The absorbent in which much of the refrigerant is dissolved is introduced into the low-pressure reactor 2 through a liquid return passage 8 via a pressure releasing unit 7; however, as a result that said absorbent is heat-insulated and expanded by the pressure releasing unit 7, it is converted from the state of a supercritical fluid into the state of gas. Consequently, the greater part of the refrigerant dissolved in the absorbent is converted from a state that the refrigerant is solvated by the absorbent into a state that the absorbent is desorbed therefrom, and heat generated as a result of this desorption reaction is utilized as cold heat. By this method, a fron gas is not used, and an air-cooled and minimized generator for cold and hot heat can be obtained.

摘要： PURPOSE:To make it possible to reduce electric power consumption compared with a higher performance coefficient and heating and cooling loads by utilizing the generation and absorption of ammonia vapor which is a heat media in a liquid state in terms of ammonia solution of sodium thiocyante. CONSTITUTION:Waste water enters a heat sink 1 from a lower part at 10 deg.C while a heat medium in a liquid state, which is ammonia of sodium thiocyante enters the heat sink from an inlet at a coordination 5 and drops through a heat transfer tube so that the waste water heats the heat medium and generates ammonia vapor. Then, the ammonia vapor is introduced from an outlet 10 to a compressor 2 and boosted there and introduced into a higher temperature side endothermic device 4. On the other hand, the liquid state-heat medium goes out from an outlet 12 and is introduced into a pump 3, boosted there are discharged. Then, the liquid state-heat medium is heat-exchanged with the respective liquid state-heat medium and ammonia vapor at an auxiliary heat exchanger 8 and an economizer 5, heated and introduced into the endothermic device 4, and drops through the heat transfer tube from an inlet 13. Moreover, the ammonia vapor rises through the heat transfer tube from an inlet 11. As a result, the ammonia vapor is absorbed into the liquid state-heat medium, discharges heat due to endothermic reaction and heat the water, thereby obtaining warm water at 45 deg.C.

摘要： PURPOSE:To obtain a small-sized cooling facility such as a cooling tower and improve the thermal efficiency of the entire system by a method wherein a condenser for a heat pump is arranged in such a way as it may be heat exchanged with highly concentrated liquid and at the same time the condenser for the heat pump is arranged in such a way as it may be heat exchanged with dilute liquid. CONSTITUTION:During an operation of heat accumulation, a highly concentrated liquid is circulated between said liquid heat exchanger 1 and a highly concentrated liquid tank 3, a dilute solution is circulated between a dilute solution heat exchanger 2 and a dilute solution tank 4, a cooling water 15 is circulated between the dilute solution heat exchanger 2 and a cooling tower 8, then a coolant compressor 18 is driven to circulate the coolant through the condenser 16 for the heat pump and an evaporator 16. Then, the concentrated liquid is heated by the condenser 16 and a part of it is evaporated and condensed. In turn, the dilute solution is cooled with cooling water 15 and cooled with the evaporator 17 and simultaneously the dilute solution may absorb vapor 11 evaporated from the concentrated liquid and then diluted.
