Title:
FIRST-TYPE THERMALLY-DRIVEN COMBINED CYCLE HEAT PUMP APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/193795
Kind Code:
A1
Abstract:
A first-type thermally-driven combined cycle heat pump apparatus. A compressor (1) is provided with a circulating working medium channel for communication with a high-temperature heat exchanger (6); the high-temperature heat exchanger (6) is further provided with a circulating working medium channel for communication with an expander (2); the expander (2) is further provided with a circulating working medium channel for communication with a heat supply device (7) and then divided into two paths, the first path is in communication with a heat regenerator (9) by means of a second expander (3), the second path is in communication with the heat regenerator (9) by means of a second compressor (4), then, the heat regenerator (9) is further provided with a condensate pipeline for communication with an evaporator (8) by means of a throttle valve (5); the evaporator (8) is further provided with a circulating working medium channel for communication with the heat regenerator (9), and the heat regenerator (9) is further provided with a circulating working medium channel for communication with the compressor (1); the high-temperature heat exchanger (6) is further provided with a high-temperature heat medium channel for communication with the outside; the heat supply device (7) is further provided with a heated medium channel for communication with the outside; the evaporator (8) is further provided with a low-temperature heat medium channel for communication with the outside; the expander (2) and the second expander (3) are connected to the compressor (1) and the second compressor (4) and transmit power. Thus, the first-type thermally-driven combined cycle heat pump apparatus is formed.
