HEAT PUMP SYSTEM, CONTROL DEVICE, TEMPERATURE ADJUSTMENT METHOD, AND PROGRAM

摘要

The refrigerant discharged from a compressor is distributed based on the priorities set by the user in advance and the remaining refrigerant is further distributed based on the priorities. Thus, setting the priorities for indoor units according, for example, to the usage of work spaces and the like in an office building, the user can operate a heat pump system efficiently in accordance with the intended use. Furthermore, the remaining capacity of the outdoor unit is distribute to the remaining indoor units according to their priorities so that the indoor units are operated efficiently within the range of the cooling capacity of the outdoor unit.

主权项

1. A heat pump system, comprising:
multiple indoor units conducting heat exchange between a temperature adjustment target and a refrigerant; an outdoor unit conducting heat exchange between the outdoor air and the refrigerant; a first circulating system circulating the refrigerant between the multiple indoor units and the outdoor unit; an adjuster provided to each of the indoor units for adjusting the flow rates of refrigerant entering the indoor unit from the first circulating system; an inputter for entering priorities set for the indoor units; and a controller controlling the adjuster and distributing the refrigerant so as to supply the indoor units with the refrigerant of the flow rates the indoor units need in the priority order of the indoor units from the highest when the total of refrigerant flow rates necessary at the multiple indoor units surpasses the refrigerant flow rate that can be discharged into the first circulating system from the outdoor unit.
