Title:
SINGLE WORKING MEDIUM COMBINED CYCLE HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/072994
Kind Code:
A1
Abstract:
Provided is a single working medium combined cycle heat pump device, which belongs to the technical field of refrigeration and heat pumps. It comprises a compressor (1), an expander (2), a throttle valve (3), a second compressor (4), a heat supply device (5), an evaporator (6) and a regenerator (7); wherein the compressor (1) communicates with the heat supply device (5) through a cycle working medium channel and then is divided into two paths, wherein a first path communicates with the regenerator (7) through the expander (2), the second path directly communicates with the regenerator (7), and then the regenerator (7) communicates with the evaporator via the throttle valve (3) through a condensate pipeline, the evaporator further communicates with the regenerator (7) via the second compressor (4) through the cycle working medium channel, and the regenerator (7) further communicates with the compressor (1) through the cycle working medium channel; the heat supply device (5) further communicates with the outside through a heated medium channel, the evaporator (6) further communicates with the outside through a low-temperature heat medium channel, and the expander (2) is connected with the compressor (1) and transmits power to form the single working medium combined cycle heat pump device.
