Absorption refrigerator

摘要

Pipings for joining pumps for delivering absorbent solution and refrigerant with an absorber and an evaporator are eliminated for minimizing the dimensions of the absorber or the evaporator, preventing leakage under pressure, and reducing heat loss and cavitation. Two pumps P2 and P3 for circulating and delivering the absorbent solution in a lower tank 21 are mounted in side-by-side relationship to a base 23 of the lower tank 21. The base 23 has a space therein for accommodating an impeller 36. The space is hence used as a part of pump chamber communicated to a flow passage 37. As the two pumps P2 and P3 are partially embedded in the base 23 and arranged integral with the lower tank 21, extra pipings will be eliminated. Also, unwanted projections from the absorber 2 will be minimized.
