Title:
SINGLE-WORKING-MEDIUM COMBINED CYCLE HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/072993
Kind Code:
A1
Abstract:
Disclosed is a single-working-medium combined cycle heat pump device, belonging to the technical field of refrigeration and heat pumps. A compressor (1) is divided into two paths after being in communication with a heat supplier (6) by means of a circulating working medium channel, wherein a first path is in communication with a heat regenerator (9) by means of a second heat supplier (7) and an expansion machine (2); a second path is in communication with a second compressor (3); the second compressor (3) is further in communication with the heat regenerator (9) by means of the circulating working medium channel, then the heat regenerator (9) is further in communication with an evaporator (8) by means of a condensed fluid pipeline via a throttling valve (4); the evaporator (8) is further in communication with the heat regenerator (9) by means of the circulating working medium channel via a third compressor (5); the heat regenerator (9) is further in communication with the compressor (1) by means of the circulating working medium channel; the heat supplier (6) and the second heat supplier (7) are further respectively in communication with the outside by means of a heated medium channel; the evaporator (8) is further in communication with the outside by means of a low-temperature heat medium channel; and the expansion machine (2) is connected to the compressor (1) and transmits power, and thereby the single-working-medium combined cycle heat pump device is formed.
