<P>PROBLEM TO BE SOLVED: To prevent a drastic increase in a temperature difference between a scroll center and a circumference edge while increasing a starting speed of a scroll compressor. <P>SOLUTION: A refrigeration cycle device is provided, including a scroll type compressor (10) compressing and discharging a refrigerant, a water-refrigerant heat exchanger (20), an expansion valve (30) with a controllable opening, and an air-refrigerant heat exchanger (40). A first temperature sensor (51, 53) detects a temperature corresponding to the temperature in the scroll center, while a second temperature sensor (52, 54) detects a temperature corresponding to the temperature in a circumference edge of the scroll. A control part (60) controls the opening of the expansion valve to prevent a temperature difference between the scroll center and the circumference edge of the scroll perimeter from exceeding a reference value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
