FOURTH-TYPE ABSORPTION HEAT PUMP AND FIFTH-TYPE ABSORPTION HEAT PUMP

摘要

Provided are a fourth type absorption heat pump and fifth type absorption heat pump. A generator (1) is in communication with a second generator (2) via a solution pump (9), a solution heat exchanger (10), and a second solution heat exchanger (11). The second generator (2) is in communication with an absorber (3) via the second solution heat exchanger (11). The absorber (3) is in communication with the generator (1) via the solution heat exchanger (10). The generator (1) has a coolant steam channel to be in communication with a condenser (4). The condenser (4) is in communication with an evaporator (6) via a coolant pump (8). The second generator (2) has a coolant steam channel to be in communication with a second condenser (5). The second condenser (5) has a coolant pipe to be in communication with the evaporator (6) via the generator (1) and a throttle valve (7). The evaporator (6) has a coolant steam channel to be in communication with the absorber (3). The second generator (2) has a driving hot medium pipe to be in communication with the external environment; the absorber (3) and the second condenser (5) have pipes for medium being heated to be in communication with the external environment; the evaporator (6) has a pipe for residual heat medium to be in communication with the external environment; the condenser (4) has a pipe for cooling medium to be in communication with the external environment, thereby forming a fourth-type absorption heat pump. The generator (1) is additionally provided with a pipe for residual heat medium to be in communication with the external environment, thereby forming a fifth-type absorption heat pump.
