Title:
REGENERATIVE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2017/208760
Kind Code:
A1
Abstract:
The present regenerative heat exchanger is provided with a refrigerant tube (11), a regenerator (20), and air conduit fins (30, 31, 32). The refrigerant tube (11) comprises a refrigerant conduit (12) through which refrigerant flows. The regenerator (20) comprises a regenerator material (22) for performing heat exchange with the refrigerant flowing through the refrigerant tube (11) and storing heat from the refrigerant, and regenerator material cases (21, 211, 212) for housing the regenerator material (22). The air conduit fins (30, 31, 32) are provided in an air conduit formed to the outside of the refrigerant tube (11) and the regenerator (20), and are thermally connected to the regenerator (20) directly or via the refrigerant tube (11). The regenerator (20) and/or the air conduit fins (30, 31, 32) are configured so that the thermal resistance between the regenerator material (22) positioned upstream and air flowing through the air conduit is greater than the thermal resistance between the regenerator material (22) positioned downstream and air flowing through the air conduit.
