The invention discloses an air-cooled modular unit, which includes a main controller; an auxiliary controller, which communicates with the main controller and connects with at least one refrigerant system, each refrigerant system includes at least one compressor, each auxiliary controller and its The correspondingly connected refrigerant system constitutes an air-cooling module; the control unit obtains the number of equivalent compressors through the capacity output power value, the number of compressors in each air-cooling module, and the compressor capacity coefficient value, and the cumulative operating time of the refrigerant system, the air-cooling module The operating refrigerant system ratio and the refrigerant system operating compressor ratio obtain the refrigerant system to load the compressor, load or unload the compressor; update the operating refrigerant system ratio and the operating compressor ratio of the refrigerant system; the main controller according to the loading The capacity factor of the compressor updates the number of equivalent compressors, and judges whether it satisfies the preset value. The invention solves the problems of low service life and low effective utilization rate of the heat exchange system existing in the existing air-cooled modular unit.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an air-cooled modular unit. Background technique [0002] The loading and unloading of the existing air-cooled module is only calculated according to the set temperature and water temperature of the air-cooled module unit. If the set temperature is not reached, the compressors are turned on one by one according to the set time period. Since the operating life of the compressor is not considered The balance problem will lead to inconsistent running hours of the compressors; since the multiple refrigerant systems in each air-cooled module of the air-cooled module unit share the water-side heat exchanger, only a simple way of turning on the compressors one by one is not conducive to air-cooling The efficiency of the modular unit is brought into play. For example, if you want to turn on two compressors, turn on one of the compressors of the refrigerant...
