An adsorption type air cooler which has a high coefficient of performance and can be stably operated over a long term. When a refrigerant vapor having evaporated by heat exchange with a load water in a refrigerant storage tank serving as an evaporator is adsorbed by an adsorbent heat exchanger, a cooling water for removing heat of adsorption is conventionally caused to circulate at a constant temperature and a constant flow rate normally determined by circumstances while according to the invention as claimed in claim (1) a temperature and a flow rate of the cooling water for removal of heat of adsorption are artificially controlled depending upon a cold output of the load water by making use of a cooling water heated after removal of heat of adsorption or a heat source water. The invention as claimed in claim (1) is an invention, in which a refrigerant storage tank and a load heat exchanging section are provided separately from each other, and a load cooler is provided for causing heat exchange between a refrigerant liquid supplied from the refrigerant storage tank through a pump and a load to cool the load while evaporating a part of the refrigerant so that gas-liquid separation is effected by returning to the refrigerant storage tank the refrigerant liquid having performed heat exchange in the load cooler, a refrigerant vapour and a mixed fluid thereof. As the refrigerant storage tank and the load heat exchanging section are provided separately from each other, an evaporative latent heat of the refrigerant is utilized independently of temperature change in the refrigerant storage tank to effect heat exchange between the refrigerant and the load whereby a load heat of a constant temperature can be obtained.

A sorber heat exchanger is provided with a substrate material incorporating a sorbent for reacting with a polar gas refrigerant or hydrogen. A preferred sorbent is a metal salt capable of reacting with the polar gas refrigerant to form a complex compound. The sorbent incorporating substrate is loaded into the reactor space between the heat transfer surfaces. Incorporating the sorbent into the substrate reduces sorbent migration thereby improving performance and life expectancy of the heat exchanger.

摘要:
In a cooling device consisting of a casing unit (1) and a cooling unit (2), the latter comprises an evaporator (3), a condenser (4) and a reactor (5). The evaporator (3), the condenser (4) and the reactor (5) form a first closed system (27) in which ammonia (8) is the working fluid and there is manganese chloride (5) in the absorber section (6) of the reactor (5). The reactor (5) has an insulating jacket (16) surrounding the absorber section (6) and a working chamber (17) filled with a working fluid (18) is left free between the insulating jacket (16) and the absorber unit (6). A second closed system (19) in the upper and lower region of the working chamber (17) is connected to said working chamber (17). The upper connection can be closed by a stop cock (24). The efficiency of the cooling device is substantially increased by heating the working fluid and hence the absorber section (6) in the regeneration phase by means of a heater (25) and by cooling the absorber section by means of the working fluid (18) during the sorption phase.
摘要:
Apparatus for producing low temperature refrigeration comprising a refrigeration sub-system (12) for circulating a first refrigerant to provide alternately two outputs (36,38) for different time periods including a first output (22,26) at a relatively warm temperature level and a second output (20,24) at a relatively cold temperature level. The sub-system outputs are furnished to a cryosorption pumping circuit (14) comprised of a closed loop conduit for a second refrigerant and connected to a plurality of sorbent beds (16,18) which cause cyclic adsorption and desorption of the second refrigerant material. External conditioning (50,52) utilizing the first refrigerant is used to cause further temperature reduction of said second refrigerant in the closed loop conduit of the cryosorption pumping circuit (14).
