Title:
HEAT REGENERATOR, AIR RETURN PIPELINE SYSTEM, AIR PATH HEAT REGENERATION METHOD, AND REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/236635
Kind Code:
A1
Abstract:
A heat regenerator (100), an air return pipeline system (1000), an air path heat regeneration method, and a refrigeration apparatus (2000). The heat regenerator (100) comprises a shell (10) and an air discharge pipe (20), wherein a heat exchange cavity (101) is formed in the shell (10); the shell (10) is provided with an air return outlet (1021) and an air return inlet (1031), which are in communication with the heat exchange cavity (101); the air return inlet (1031) is used for receiving a refrigerant from an evaporator (500); the air return outlet (1021) is used for transferring the refrigerant into a compressor (200); the air discharge pipe (20) is arranged in the heat exchange cavity (101) and is coiled; an air discharge inlet (201) and an air discharge outlet (202) are formed at two ends of the air discharge pipe (20); the air discharge inlet (201) is used for receiving a refrigerant from a condenser (300); and the air discharge outlet (202) is used for transferring the refrigerant into a capillary tube (400).
