Title:
FREEZING APPARATUS
Document Type and Number:
Japanese Patent JP3956589
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a freezing apparatus capable of realizing energy saving and low GWP while avoiding deterioration of reliability and performance.
SOLUTION: The present freezing apparatus controls in a control section 8 revolutions of a compressor 1 and an opening of an expansion valve 3, and further controls the degree of drying of an R32 refrigerant (superheat SH) on a suction side of the compressor 1 to a range of from 0.75 to 0.85. Hereby, discharge temperature is more lowered than prior art, and hence energy saving and low GWP are realized while avoiding deterioration of reliability and performance.
