Title:
PHASE-CHANGE HEAT PUMP SYSTEM AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/077990
Kind Code:
A1
Abstract:
The present application belongs to the technical field of mechanical design. Disclosed are a phase change heat pump system and a terminal device. The phase-change heat pump system comprises a reversing device, a first heat exchanger, a second heat exchanger, a compressor and a phase-change heat exchanger, wherein the compressor, the first heat exchanger and the second heat exchanger are in communication by means of the reversing device. The phase-change heat exchanger comprises a first box body and a phase-change material, wherein the first box body is filled with the phase-change material; and the phase-change heat exchanger is in contact and in thermal communication with the first heat exchanger. When the reversing device is in a first working state, an air suction port is in communication with the first heat exchanger, and an air discharge port is in communication with the second heat exchanger; and when the reversing device is in a second working state, the air suction port is in communication with the second heat exchanger, and the air discharge port is in communication with the first heat exchanger. By using the solution, the first heat exchanger can actively heat the phase-change material, such that, compared with the related art, the solution significantly shortens the regeneration time for the phase-change material, thereby being beneficial to improving the working efficiency of the phase-change heat pump system.
