Steam compressed type refrigeration system

摘要

Topic There is in defrost operation a margin, from it guarantees in the refrigerating cycle which installs the thermal self balance heat exchanger which is known until recently thing, and the refrigerating effect and the security which obtain more perfection and the perfect defrost effect, it is the dot that it was insufficient. Solutions Being the steam compressed type refrigerating cycle which possesses the process of compression, condensation, expansion and evaporation of the refrigerant, it possesses primary side and downstream as one unit, that primary side and downstream install the identical area of heat-transfer surface and the thermal self balance heat exchanger which has capacity, it has the primary expansion valve for also the refrigerant entrance of the primary side where the refrigerant of the aforementioned thermal self balance heat exchanger is introduced in the steam compressed type refrigeration system which provides the expansion valve for the refrigerant entrance of downstream of this thermal self balance heat exchanger.
