PROBLEM TO BE SOLVED: To save energy by suppressing the supercooling reheating when a dehumidification load is not present. SOLUTION: When a measured indoor humidity is lower than a set indoor humidity, a set level Tsp of supply air temperature is determined by optimization control. More specifically, the set level Tsp of supply air temperature is lowered by a specified level if the current exhibition capacity value of a reheater is lower than a minimum capacity set value otherwise the set level Tsp of supply air temperature is raised. Supercooling reheating is eliminated by preventing the set level Tsp of supply air temperature from lowering (P1'-P2'1 shown at (b), Pi"-P2" shown at (c)) down to a level (Tsp shown at (a)) for dehumidifying down to the set indoor humidity. |
