Title: Vapor compression refrigerator
Inventor: NAKAJIMA MASAFUMI
IPC: B60H1/32
Filed: 2001-08-01
Abstract: PROBLEM TO BE SOLVED: To ensure control of discharge of a compressor even if the compressor is started in the state where the pressure in a vapor compression refrigerator is equalized (i.e., the state where there is little difference between high and low pressures). SOLUTION: Heat exchange of a radiator 200 is suppressed by stopping first and second fans 210, 410 to prevent lowering of a discharge side refrigerant temperature (high and low pressure difference) during a period of starting the compressor 100 until exceeding a given level Ph of a discharge pressure Pd. Thus, even if the compressor 100 is started in the state where the pressure in the vapor compression refrigerator is equalized (i.e., the state where there is little difference between high and low pressures), the discharge side refrigerant pressure (high and low pressure difference) can be raised promptly. Accordingly, control of discharge of the compressor 100 is ensured, and a sufficient (heating) capacity is exerted immediately after the compressor is started.
