Abstract

The invention provides a method and device for monitoring the operation state of an air conditioner. The method comprises the steps that air temperatures of discharged air and return air of each indoor unit of the air conditioner and the blowing rate of each indoor unit are detected; according to the air temperatures of discharged air and return air of each indoor unit of the air conditioner and the blowing rate of each indoor unit, the refrigerating capacity or the heating capacity of the whole air conditioner unit is calculated; according to the refrigerating capacity or the heating capacityof the whole air conditioner unit, the energy efficiency index of the air conditioner is calculated; and according to the energy efficiency index of the air conditioner, the operation state of the air conditioner is judged. The method and device for monitoring the operation state of the air conditioner achieve prediction of fault of VRV air conditioner equipment, the operation and maintenance personnel can conveniently make a reasonable solution, posterior maintenance (emergency repair) is avoided, and the operation reliability of the VRV air conditioner is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and device for monitoring the running state of an air conditioner. Background technique [0002] VRV (Variable Refrigerant Volume) air-conditioning system——variable refrigerant flow multi-connected air-conditioning system (referred to as multi-connected), by controlling the refrigerant circulation volume of the compressor and the refrigerant flow into the indoor heat exchanger, it can meet the indoor cooling and cooling requirements in a timely manner. Direct evaporative cooling systems for heat load requirements. At present, the maintenance method of VRV air conditioners is still the traditional post-event maintenance, that is, the equipment is repaired after the equipment is broken, so that the work is unplanned and the operation and maintenance are inconvenient. Contents of the invention [0003] In order to solve the problem of inconvenient operation and maintenanc...
