摘要： PURPOSE:To enable a refrigerant piping system to be performed most appropriately by a method wherein in case that a liquid surface of an air-cooled condensor is placed at a lower position than that of a liquid surface in an evaporator, condensing refrigerant is returned back to the evaporator by a pump and another refrigerant in the evaporator is returned back from a dam means to an air-cooled absorber device through a piping system. CONSTITUTION:A refrigerant pump 6 is arranged in a refrigerant returning pipe 5 as means for feeding refrigerant having a capability to exceed a working pressure liquid column height. A condensed refrigerant is returned from an air-cooled condensor 3 to an evaporator 1 under a pump operating power. When solution shows a high concentration and the refrigerant is abnormally separated, the refrigerant is overflown over an opening dam 9 formed at a refrigerant container of the evaporator 1. The refrigerant passes an over-flow pipe 10, the refrigerant flows to the solution container of an air-cooled absorber device 14 so as to dilute the solution. With such an arrangement as above, a liquid surface 2 of the evaporator is higher than a liquid surface 4 of the air-cooled condensor. Even in case that it is higher than a differential pressure liquid column head, the liquid refrigerant can be returned positively from the air-cooled condensor 3 to the evaporator 1. The refrigerant over-flow in the evaporator 1 in properly attained and then a double-effected air-cooled absorption type refrigerator can be operated safely.

摘要： PROBLEM TO BE SOLVED: To provide an absorption refrigerator having an absorber excellent in efficiency for a long period. SOLUTION: A two-stage absorption refrigerator 100 has an integral can body provided at an upper part with a low pressure evaporator 1 and a low pressure absorber 2 and at a lower part with a high pressure evaporator 3 and a high pressure absorber 4. Non condensible gas generated by a high temperature regenerator 9 is gradually moved to the low pressure side together with circulation of a refrigerant and a solution. The gas gathering in the high pressure absorber 4 is extracted by gas extracting means 17, 22b, and 22 and gas gathering in the lower pressure absorber 2 is extracted by an ejector 16. The extracted non condensible gas is stored in a gas storage tank 20 through a gas liquid separator 19. A valve 33 is annexed to the gas storage tank and when a pressure in the gas storage tank exceeds a given value, a valve is opened and the non condensible gas is discharged from the gas storage tank to the outside of the absorption refrigerator by an ejector 21.
