<P>PROBLEM TO BE SOLVED: To provide a refrigeration cycle device that can minimize decline in cooling capacity and efficiency even when noise is reduced. <P>SOLUTION: The refrigeration cycle device includes a refrigerant circuit, a timer 15 and a control circuit 11. The refrigerant circuit is configured by sequentially interconnecting a compressor 1, a condenser 2 having an outdoor fan motor 3, an expansion valve 4 and an evaporator 5 by a refrigerant pipe 6, and heat is exchanged between a refrigerant and water within the evaporator 5. The control circuit 11 sets each frequency of the compressor 1 and the outdoor fan motor 3 combined by placing great importance on either of the capacity or efficiency of the refrigerant circuit for each time, determines time on the basis of timing by the timer 15, selects each frequency of the compressor 1 and the outdoor fan motor 3 on the basis of the time, controls rotational frequency of each of the compressor 1 and the fan motor 3 on the basis of the selected frequency, and reduces noise caused by the compressor 1 and the outdoor fan motor 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
