Abstract (en)
An air-conditioning refrigerating system that enables demand control based on operation control of an air-conditioning system and a refrigerating system is provided. The air-conditioning refrigerating system 1 is constructed to have an air-conditioning system 10 in which plural indoor units 34 are connected to an outdoor unit 32 to air-condition a building, a refrigerating system 12 in which plural low-temperature showcases 7 are connected to a rack system refrigerating machine 3 to cool each of the low-temperature showcases 7, a main controller 4 for generating and outputting air-conditioning demand data for varying power consumption of the refrigerating system and refrigerating demand data for varying power consumption of the refrigerating system 12 on the basis of commercial power consumption of the building, and an external controller 14 that is provided separately from the refrigerating system 12, receives the refrigerating demand data from the main controller 4 and controls the operation of the rack system refrigerating machine on the basis of the refrigerating demand data.
