Abstract (en)
A refrigerated showcase 30 including: a refrigeration circuit 20 annularly formed by connecting, to one another through a refrigerant pipe, a compressor 1, a condenser 2, a decompression device 3 and an evaporator 4; a fan 5 for blowing air to the evaporator 4 and circulating the air; a temperature sensor 6 for detecting temperature of the air; and a control device 8, wherein the control device 8 stops the operation of the compressor 1 when detected temperature of the temperature sensor 6 reaches the predetermined value 1 during high speed operation of the compressor 1 in which the number of operational rotations thereof is constant, and thereafter, when the detected temperature of the temperature sensor 6 reaches the predetermined value 2, the compressor 1 is made to execute the high speed operation and, when the detected temperature of the temperature sensor 6 reaches the predetermined value 3, the number of operational rotations of the compressor 1 is controlled, and the number of operational rotations of the compressor 1 is reduced stepwisely. According to this, a cooling effect and energy-saving operation of the refrigerated showcase 30 are realized.
