Document Type and Number:
Japanese Patent JP3593476
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce (silence) the noise occurring from a motor-operated valve as a change-over valve. SOLUTION: Since the initialization of a motor-operated three-way valve 20 is put into practice after a compressor 17 is driven and a refrigerant gets to circulate in liquid state inside the motor-operated three-way valve 20, the liquid refrigerant works as shock absorbing material thereby reducing the noise generated at the time of initialization. Along with the drive of the compressor 17, a fan 11 for a cold storage chamber or a fan 15 for a freezing chamber, and a fan 18 for cooling of a compressor are driven, so the noise generated at initialization is silenced by the operation sound of this fan 11 or 15 or the operation sound of the compressor 17. Moreover, the switching action of the motor-operated three-way valve 20 is performed after the refrigerant gets to circulate in liquid state inside the motor-operated three-way valve 20, too.
