PROBLEM TO BE SOLVED: To improve the following property to the ripple of load, by computing the air supply temperature set value, based on the indoor set temperature inputted in advance and the measured return air temperature, and further, opening and closing a flow control valve for cold/hot water by PI action using the air supply set value. SOLUTION: This air conditioner is equipped with a temperature measuring instrument 3 which measures the temperature PV of return air sucked in a cold/hot water coil 2, a temperature measuring instrument 4 which measures the temperature of the supply air discharged from the cold/hot water coil 2, a supply air temperature set value operating part 5 which computes the set value SP of the supply air temperature, based on the measured return air temperature PV and the indoor set temperature SPO inputted in advance, and a quantity-of-PI-action operating part 6 which computes valve travel to make a cold/hot water valve MV1 perform PI action, using the measured supply air temperature and the computed supply air temperature set value SP. |
