Title:
冷凍サイクル装置
Document Type and Number:
Japanese Patent JP4407870
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrain the deterioration of efficiency of a refrigerating cycle, in the low-pressure side refrigerant pipeline of an ejector cycle due to heat exchange with the outdoor air. SOLUTION: Both of refrigerant pipelines P1, P2 are covered by a heat- insulating member 7 for restraining the movement of heat under the condition of a part or the whole of a liquid phase refrigerant supplying pipeline P1 for connecting an ejector body gas and liquid separator 3 and an evaporator 5, as well as an evaporated refrigerant recovering pipeline P2, being bundled. According to this method, both of the refrigerant pipelines P1, P2 are covered by the heat-insulating member 7 under the condition that both of refrigerant pipelines P1, P2 are bundled, whereby both of the refrigerant pipelines P1, P2 can be insulated, while decreasing a surface area in reference to the heat transfer between outdoor air and refrigerant in the liquid phase refrigerant supplying pipeline P1 and the evaporated refrigerant recovering pipeline P2, whereby the deterioration of efficiency of the refrigerating cycle can be restrained.
