A temperature control method, device, storage medium and air conditioner

Abstract

The invention discloses a temperature control method and device, a storage medium and an air conditioner. The method comprises the steps that an operation load of the air conditioner is determined; ifthe operation load of the air conditioner is a first load, a power consumption parameter, a photovoltaic power generation parameter and a rectifier module temperature of a frequency converter of theair conditioner are acquired, and first control is carried out on a frequency converter temperature of the air conditioner according to the power consumption parameter, the photovoltaic power generation parameter and the rectifier module temperature; and if the operation load of the air conditioner is a second load, the power consumption parameter, the photovoltaic power generation parameter, therectifier module temperature of the frequency converter and a compressor suction superheat degree of cooling equipment of the air conditioner are obtained, and second control is carried out on the frequency converter temperature of the air conditioner according to the power consumption parameter, the photovoltaic power generation parameter, a frequency converter temperature rising rate and the compressor suction superheat degree. According to the scheme of the method, the problem that the working reliability of the frequency converter is influenced by heat generated by the frequency convertercan be solved, and the effect of radiating the heat generated by the frequency converter to improve the working reliability of the frequency converter is achieved.
