PROBLEM TO BE SOLVED: To stabilize the temperate of air by providing two passages in an evaporator, and controlling to interrupt one passage in the evaporator when the temperature of the supplied air is continuously lower by a prescribed value or more than a control target value for a prescribed time and supply a refrigerant to the two passages when the temperature of supplied air is continuously higher by a prescribed value or more than the target value for a prescribed time. SOLUTION: An air condiutioner for cooling a computer or the like comprises an evaporator 10 having two passages respectively provided with electronic expansion valves 8 and 9. When the load of the computer or the like decreases and the temperature of supplied air is continuously lower by a prescribed value or more than a control target value for a prescribed time, which exceeds a tolerance range of adjusting a reheating cycle including an auxiliary heat exchanger 12, the electronic expansion valve 9 is completely closed so that one passage in the evaporator 10 is interrupted, a cooling capability is lowered and the temperature of supplied air is adjusted. When the temperature of supplied air is continuously higher by a prescribed value or more than the control target value for a prescribed time because of the increase of the load or the like, the electronic expansion valve 9 is opened so that the temperature of the supplied air is adjusted ad room air temperature is maintained at the control target value. |
