Title:
HIGH-EFFICIENCY ABSORPTION HEAT PUMP SYSTEM HAVING INCREASED UTILIZATION RATE OF WASTE HEAT SOURCE
Document Type and Number:
WIPO Patent Application WO/2018/194221
Kind Code:
A1
Abstract:
The present invention comprises: an evaporator to which a waste heat source supply line, through which a waste heat source flows in, is connected so as to enable thermal energy to be absorbed from the waste heat source and to which a refrigerant supply tube for supplying a refrigerant is connected; an absorber connected to the evaporator such that steam evaporated in the evaporator is supplied thereto, and to which a hot water inflow tube and a hot water discharge tube extending from a flash tank are connected; a high-temperature regenerator through which a waste heat source branch tube branching off from the waste heat source supply line passes and which heats an absorption liquid supplied to the absorber so as to regenerate the same and is provided with a concentrated solution tube for supplying the absorption liquid to the absorber; an auxiliary absorber to which the steam evaporated in the high-temperature regenerator is delivered and which is connected to the high-temperature regenerator so as to cool the steam and circulate the same; a low-temperature regenerator to which an intermediate solution tube is connected so as to supply the absorption liquid to the high-temperature regenerator, through which a waste heat source recovery line extending from the evaporator passes, and to which a dilute solution tube extending from the absorber is connected; a condenser through which a cooling water line for supplying cooling water passes such that the steam evaporated in the low-temperature regenerator is supplied and cooled therein, and which is connected to the low-temperature regenerator; and an auxiliary regenerator to which an auxiliary solution tube is connected so as to supply an auxiliary absorption liquid to the auxiliary absorber, through which the waste heat source branch tube passes, and to which an auxiliary dilute solution tube extending from the auxiliary absorber is connected.
