LOCAL AIR CONDITIONING SYSTEM

PROBLEM TO BE SOLVED: To prevent occurrence of a problem such as a liquid back flow even when a refrigerant temperature is raised while preventing occurrence of dew condensation by dew condensation avoidance control.SOLUTION: A limit value (lower limit value) of a blowoff cold air temperature is calculated (S1) on the basis of measurement values of a sucked warm air temperature and a refrigerant temperature and a heat exchange characteristic (temperature efficiency ) of an evaporator 6, and when the limit value exceeds a target value (set temperature) (S2, YES), an inner target value to be a temperature higher than the set value is determined as a target value of the blowoff cold air temperature in stead of the set temperature. Then the inner target value is adjusted and controlled so as to become approximately the same value as the limit value (S3, S4, S5, S6, S7, S9).
