Title: REFRIGERATION AIR CONDITIONING SYSTEM
Abstract:
This refrigeration air conditioning system comprises a plurality of independent refrigeration air conditioners G1 - G4 that have a refrigerant circuit and a defrosting means, and a system controller 100 that performs integrated management of these. A defrost operation controlling means for the system controller 100 transmits a defrost start command signal to the defrosting means of a certain refrigeration air conditioner when the time interval between a calculated scheduled defrosting start time for the certain refrigeration air conditioner and the most recent scheduled defrosting start time, after calculations for another refrigeration air conditioner, is a preset target start time interval or shorter.
