吸収ヒートポンプ
Document Type and Number:
Japanese Patent JP6397747
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an absorption heat pump capable of being stably started even when an absorber of a low operation temperature is placed on a position where an absorbent cannot be introduced by a positional head.SOLUTION: An absorption heat pump 1 includes a regenerator 70 producing a high-concentration absorbent Sa increased in concentration by evaporation of a refrigerant by heating a diluted solution Sw, a high-temperature absorber 10 for heating a heated medium W by absorption heat generating in absorbing vapor Va of the refrigerant by the high-concentration absorbent Sa introduced from the regenerator 70, a low-temperature absorber 50 which is disposed at a height free from inflow of the absorbent Sb of which the concentration is lowered in the high-temperature absorber 10 by a positional head, and heats the refrigerant by absorption heat generating when the introduced absorbent Sb absorbs the vapor Vc of the refrigerant, and absorbent returning means 36 for directly or indirectly guiding the absorbent Sb of lowered concentration of the high-temperature absorber 10 to at least one of the low-temperature absorber 50 and the regenerator 70.SELECTED DRAWING: Figure 1
