Title:
SINGLE-WORKING-MEDIUM COMBINED CYCLE HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/068431
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 (5) by means of a circulating working medium channel, with the first path being in communication with a heat regenerator (8) by means of an expansion machine (2), and with the second path being in communication with a second compressor (3) by means of a second heat supplier (6), wherein the second compressor (3) is further in communication with the heat regenerator (8) by means of the circulating working medium channel, and the heat regenerator (8) is then in communication with an evaporator (7) by means of a condensate pipeline via a throttling valve (4); the evaporator (7) is further in communication with the heat regenerator (8) by means of the circulating working medium channel; the heat regenerator (8) is further in communication with the compressor (1) by means of the circulating working medium channel; the heat supplier (5) and the second heat supplier (6) are respectively further in communication with the outside by means of a heated medium channel; the evaporator (7) is further in communication with the outside by means of a low-temperature medium channel; and the expansion machine (2) is connected to the compressor (1) and transmits power, and the single-working-medium combined cycle heat pump device is thus formed.
