Variable frequency air conditioner control method

Abstract

The invention discloses a variable frequency air conditioner control method. The variable frequency air conditioner control method comprises the following steps that (1) a load calculation function atwhich the indoor load changes along with indoor temperature and humidity is obtained; (2) the indoor load corresponding to each temperature and humidity combination in a temperature and humidity parameter library is calculated according to the load calculation function obtained in the step (1); (3) the air conditioner energy consumption corresponding to each temperature and humidity combination is calculated according to the temperature and humidity combination in the temperature and humidity parameter library and the indoor load corresponding to the temperature and humidity combination through a pre-established relation model between the indoor load and the air conditioner operating state; and (4) according to the air conditioner energy consumption corresponding to the temperature and humidity combination in the temperature and humidity parameter library and the indoor comfort degree, the set temperature and humidity combination is determined by using a temperature and humidity setting function, and an air conditioner temperature and humidity control module controls the indoor temperature and humidity to be the set temperature and humidity combination. Thus, the temperature and humidity combination is determined through the temperature and humidity setting function, the indoor comfort degree is met, meanwhile, the relatively low energy consumption is achieved, and the comfortdegree and the energy consumption are both considered at the same time.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control methods, in particular to an inverter air conditioner control method. Background technique [0002] Air conditioners on the market today often only have temperature control functions, and most of the research work on reducing energy consumption of air conditioners is focused on improving equipment performance (such as improving compressor performance or improving heat exchanger efficiency, etc.). In contrast, the control objectives and strategies of air conditioners are relatively simple. On the basis that the air conditioner only has the function of temperature control, if the control target is optimized to achieve energy saving, it is usually at the expense of comfort. [0003] In order to improve the comfort of the air conditioner and realize the simultaneous control of temperature and humidity, some scholars have proposed a PID fuzzy logic control method based on the w...

On the other hand, indoor temperature and humidity control will affect the indoor load and energy efficiency of the air conditioner, thereby affecting the total energy consumption of the air conditioner.

[0005] However, at present, there is no inverter air conditioning control method that can take into account both temperature and humidity control and energy consumption optimization. By optimizing the appropriate indoor temperature and humidity set point, it can meet indoor comfort and have low energy consumption.
