Abstract

The invention discloses a control method and a device of air-conditioning equipment and an air conditioning system. The control method comprises the following steps of: step S101, carrying out comparison on the water-outlet temperature of an evaporator and set object temperature, and determining the object load value of the compressor of the air-conditioning equipment; step S103, determining the variation of the load value of the air-conditioning equipment according to the object load value and the current load value of the compressor of the air-conditioning equipment; and step S105, adjusting the current load value of the compressor of the air-conditioning equipment according to the determined variation value. According to the invention, an object load is obtained through collecting the backwater temperature of an evaporator, the load of the compressor is adjusted according to the object load, and more accurate reference can be used for rationally adjusting a working mode of an air conditioner compressor; and the frequent adjustment of the compressor is avoided, the display of the system performance is more stable, and the service life of the compressor is guaranteed.

Description

technical field [0001] The present invention relates to the field of electrical equipment, and in particular, relates to a control method and device for air-conditioning equipment, and an air-conditioning system. Background technique [0002] Usually, the energy control of air-cooled chillers uses water temperature (water outlet or return water) as the target control amount, and the compressor is adjusted and controlled according to 4 stages, 25% or 33% is used as the starting energy stage, and it enters 50 after running for 1-2 minutes. % energy section, and then according to the difference between the actual water temperature and the target water temperature as the load increase and decrease control amount, adjust the energy state of the unit to run between 25%--100%, so as to adjust the compressor to run in different energy state sections; under partial load conditions , it is prone to mismatch between the demand and the operating state of the compressor, resulting in fre...
