A method, device and system for controlling an inverter air conditioner

Abstract

The invention discloses a control method, device and system for a variable-frequency air conditioner. The method comprises the following steps: receiving an off-peak power consumption control command; judging the type of the off-peak power consumption control command; and adjusting the operating frequency of a compressor of the variable-frequency air conditioner according to the type of the off-peak power consumption control command, and controlling the actual operation frequency of the compressor of the variable-frequency air conditioner to be within the range required by the type of the off-peak power consumption control command. As the operating frequency of the compressor of the variable-frequency air conditioner is adjusted according to the type of the off-peak power consumption control command, the actual operation frequency of the compressor of the variable-frequency air conditioner is controlled to be within the range required by the type of the off-peak power consumption control command, and the power consumption of the variable-frequency air conditioner is reduced through controlling the operating frequency of the compressor of the variable-frequency air conditioner, so that the requirement for off-peak power consumption is satisfied without stopping power supply for users, enterprises, factories and other power consuming units do not need to stop the current production activities, accordingly, unnecessary economic loss caused by power failure production stop are avoided, and management control is facilitated more.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to a control method, device and system for an inverter air conditioner. Background technique [0002] With the development of society, human social activities require more and more electricity. At this stage, under normal load conditions, my country's power supply can meet the demand for electricity consumption. The shortage of power supply is mainly caused by the high peak power consumption and the large load difference of the power grid. [0003] In order to ensure the normal power consumption of some functional departments, such as hospitals, schools or transportation units, many large cities will transfer the peak power consumption of the power grid to the low power consumption period through administrative, technical or economic means according to the load characteristics of the power grid. Thereby reducing the peak-valley load difference of the power g...

Problems solved by technology

With the popularization of air conditioners, the power consumption of air conditioners is the largest electricity consumption during this time period. Moreover, almost every room will have an air conditioner installed. During cold or hot periods, every household and major enterprises and institutions use air conditioners at the same time, which is easy. The power supply is tense, causing the power station to trip or explode
