Title:
HEAT REGENERATOR AND REFRIGERATION SYSTEM HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/068306
Kind Code:
A1
Abstract:
Disclosed in the present invention are a heat regenerator and a refrigeration system having same. The heat regenerator comprises: an outer housing enclosing a gas-liquid separation chamber, and an inner housing positioned in the gas-liquid separation chamber and enclosing a liquid storage chamber separated from the gas-liquid separation chamber, wherein a plurality of heat exchange pipes are arranged in the liquid storage chamber, and each heat exchange pipe is provided with a first end and a second end, the first end being in communication with the gas-liquid separation chamber. The outer housing is provided with: a gaseous refrigerant input interface, which is positioned close to the lower part of the gas-liquid separation chamber and is in communication with the second ends of the heat exchange pipes; at least one gaseous refrigerant output interface extending to the upper part in the gas-liquid separation chamber; and a liquid refrigerant input interface and a liquid refrigerant output interface, wherein the liquid refrigerant input interface extends to the upper part in the liquid storage chamber, and the liquid refrigerant output interface extends to the lower part in the liquid storage chamber. The heat regenerator integrates the functions of a gas-liquid separator and a liquid storage device, and overcomes the problem of the refrigerant separated by a traditional gas-liquid separator not being prone to evaporating. The corresponding refrigeration system has a higher energy efficiency ratio.
