摘要： An adsorption refrigeration system comprising adsorption columns housing a solid adsorbent and heat transfer tubes and sealed with a refrigerant, an evaporator, a condenser, and pipe lines connecting them together so that the refrigerant may be circulated, the pipe lines being equipped with valves, preferably, butterfly valves, capable of opening or closing by means of internal pressure difference between the evaporator side and condenser side and driving force of eccentric valve shafts. The system is operated by alternatively changing over adsorption and desorption stages between the one adsorption column(s) and the other column(s) so that both columns may be at mutually reverse stages; shortly before change-over, transferring whole amount of heat remained in the one column(s) immediately before shifting from desorption to adsorption stage to the other column(s) immediately before shifting from adsorption to desorption stage where the preheat the adsorbent and then reversing the stages. The evaporator preferably comprises heat transfer tubes for passage of a heating medium on a utilization side arranged in multi-stage, evaporating plates holding the refrigerant liquid in which each stage of the tubes are partly immersed, and overflow members for adjusting the liquid level, whereby evaporating ebullition occurs briskly.

摘要： An adsorption refrigerator includes a vacuum vessel within which a required amount of refrigerant is hermetically filled, and there are housed a first finned tube for routing therethrough a heating medium on the heat source side, which tube has an adsorbent packed and held in fin interstices, and a second finned tube for routing therethrough a heating medium on the utilization side, which tube serves as a vaporizer and condenser. The refrigerator further may be provided, at the bottom portion of the vessel, with refrigerant heating means for heating and vaporizing the refrigerant during desorption. Otherwise, where the amount of refrigerant is adjusted, the refrigerator may be provided with refrigerant heating and cooling means for heating to vaporize the refrigerant during desorption and for cooling to condense refrigerant vapors, at the bottom portion of the vessel, and with a refrigerant reservoir for reception of the adjusted amount of refrigerant, which reservoir is connected through a line and valve to the bottom of the vessel, below the bottom of the vessel. The first finned tube preferably has a fin pitch of 1 to 10 mm and a fin height of 5 to 20 mm. With the refrigerator, even low-temperature fluid of less than 80.degree. C. may be utilized for the heat source-side heating medium.
