Problems solved by technology

[0004] However, the applicant found that when the air conditioner is controlled by starting and stopping the compressor, the indoor temperature fluctuates greatly, and the environment is hot and cold, which reduces the user's comfort. At the same time, frequent starting and stopping of the compressor will reduce the service life of the air conditioner and cause waste of power resources

Embodiment Construction

[0029] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0030] The embodiments of the present application are mainly aimed at the refrigeration control of the fixed-frequency air conditioner in the related technology. Stop working, the air conditioner stops cooling. When the room temperature is higher than the set temperature of the air conditioner and reaches the preset value, the compressor starts to work. When the air conditioner continues to cool, the indoor temperature fluctuates greatly, and the environment is hot and cold, which affects the user experience. Technical probl...

Abstract

The application brings forward a fixed-frequency air-conditioning system, a control method and device of the fixed-frequency air-conditioning system, an electronic device and a storage medium. The method comprises the following steps: detecting air intake temperature of an indoor heat exchanger when the system operates in a refrigeration mode; obtaining temperature difference value between the airintake temperature and the set temperature of the fixed-frequency air-conditioning system; and adjusting the opening degree of an electronic expansion valve according to the temperature difference value and controlling a compressor to start and close. Through the electronic expansion valve, quantity of coolants entering the indoor heat exchanger is adjusted in order to fulfill the purpose of precisely controlling indoor temperature. The indoor temperature is kept stably close to the set temperature. Therefore, a user feels more comfortable. The compressor is prevented from frequent start andstop.

Description

technical field [0001] The present application relates to the technical field of electrical appliance control, and in particular to a fixed-frequency air-conditioning system, a control method, a device, an electronic device, and a storage medium for the fixed-frequency air-conditioning system. Background technique [0002] With the improvement of air-conditioning popularity, people use air-conditioners more widely in their lives to adjust the temperature of the indoor environment to meet the cooling and heating needs of users. [0003] In related technologies, for the cooling control of fixed-frequency air conditioners, the method of reaching the temperature and stopping is generally adopted, that is, in the cooling state of the air conditioner, when the room temperature is lower than the set temperature of the air conditioner and reaches the preset value, the compressor stops working, and the air conditioner stops cooling. , when the room temperature is higher than the set ...
