Title:
SINGLE-WORKING MEDIUM COMBINED CYCLE HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/072989
Kind Code:
A1
Abstract:
A single-working medium combined cycle heat pump device. A compressor (1) is provided with a circulation working medium channel which is in communication with a heat supply device (6) and then is divided into two paths: a first path is in communication with a heat regenerator (8) by means of an expander (2), and a second path is directly in communication with a second compressor (3); the second compressor (3) is also provided with a circulation working medium channel in communication with the heat regenerator (8), and then the heat regenerator (8) is also provided with a condensation liquid pipeline which is in communication with an evaporator (7) by means of a throttle valve (4), the evaporator (7) is also provided with a circulation working medium channel in communication with the heat regenerator (8) by means of a third compressor (5), the heat regenerator (8) is also provided with a circulation working medium channel in communication with the compressor (1); the heat supply device (6) is also provided with a heated medium channel in communication with the outside, the evaporator (7) is also provided with a low-temperature heat medium channel in communication with the outside, and the expander (2) is connected to the compressor (1) and transmits power, thereby forming a single-working medium combined cycle heat pump device.
