Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/001667
Kind Code:
A1
Abstract:
A refrigeration device having a super cooling circuit (1a) for enhancing cooling ability
and a main refrigerant circuit (1b) for cooling a target cooling space. Even if
the refrigeration device is not in an overloaded condition, high pressure equivalent
control in which the pressure of a high pressure refrigerant in the main refrigerant
circuit (1b) and the pressure of a high pressure refrigerant in the super cooling
circuit (1a) are brought closer to each other is performed in order to improve
the performance coefficient of the refrigeration device. Such control is performed
by operating a second variable displacement compressor (20) for controlling
the super cooling ability of the super cooling circuit (1a).
