Problems solved by technology

In this case, there will be frost formation on the surface of the refrigerating room evaporator 105, therefore, there will be undesirable obstacles to maintaining a high percentage of humidity in the refrigerating room.
Moreover, the evaporating efficiency of the refrigerating room evaporator 105 will be reduced, therefore, the cooling efficiency of the refrigerator will be reduced.
Considering the refrigerant evaporating temperature required by the freezing chamber evaporator 107, and the refrigerant must be compressed in the compressor 101, the load on the compressor 101 is increased, thereby reducing the energy of the cooling device Efficiency ratio

Abstract

A two-compartment cooling apparatus which achieves a plurality of refrigeration cycles by controlling refrigerant paths, thus increasing cooling efficiency and cooling speed of the cooling apparatus. A compressed refrigerant provided by a compressor is selectively provided to first and / or second evaporators via first, second and third expansion units and a path control unit. The path control unit controls the flow of the refrigerant through the expansion units and the evaporators to vary the cooling in the respective compartments in response to temperature measurements made in the respective compartments.

Description

technical field [0001] The present invention generally relates to a cooling device and in particular to a cooling device with two or more cooling chambers which can be cooled independently. Background technique [0002] Generally, an independent cooling type cooling device is divided into two cooling rooms, ie, a freezing room and a refrigerating room, by a partition wall. Two doors are hinged to the cabinet of the unit. Each of the two doors opens and closes a respective cooling chamber. An evaporator and a fan are installed on the inner surface of the freezer to generate and supply cool air to the freezer. Also, an evaporation chamber and a fan are provided on the inner surface of the refrigerating chamber to generate and supply cool air to the refrigerating chamber. That is, cold air may be independently supplied into the freezing chamber and the refrigerating chamber. This cooling technique is called independent cooling technique. [0003] figure 1 Shown is a view ...
