Abstract:
PROBLEM TO BE SOLVED: To restrict an energy loss when cold heat or hyperthermia is supplied from a heat source unit to several utilization units to perform a preheating operation.SOLUTION: A control part for an air conditioning control device 40 has a preheating mode in addition to a normal operation mode. At the preheating mode, the control is carried out in accordance with a heat supplying distribution schedule for several indoor units 30a, 30b, 30c determined to cause an outdoor unit 20 to keep a predetermined high efficiency operation. The control part can carry out a scheduling for a state in which only a part of indoor units 30a, 30b, 30c is being pre-heated for a predetermined time band or, under the preheating mode, carry out a scheduling in such a way that at least one unit of several utilization units may gradually increase an air conditioning ability and at least the other unit of several utilization units may gradually decrease the air conditioning ability.SELECTED DRAWING: Figure 1
