Abstract (en)

A control device of a multiple-type air conditioning device configured to perform control to adjust refrigerant when a necessary amount of refrigerant varies, the multiple-type air conditioning device, a method of controlling the multiple-type air conditioning device, and a computer program of controlling the multiple-type air conditioning device are provided. The present invention provides a control device 70 of a multiple-type air conditioning device 1 including at least one outdoor unit 2, and a plurality of indoor units 3 each including an indoor electronic expansion valve 31. Each indoor unit 3 in operation is referred to as an operation indoor unit 3, each operation indoor unit 3 in heating operation is referred to as a heating operation indoor unit 3, and each indoor unit 3 at a stop is referred to as a stop indoor unit 3. At heating, when the difference between an exit temperature T1 and a central-part temperature T2 of an indoor heat exchanger 30 included in each heating operation indoor unit 3 becomes equal to or lower than a first temperature difference and the amount of refrigerant is sensed to be excessive, control is performed to close the indoor electronic expansion valves 31 of all stop indoor units 3.
