Problems solved by technology

[0003] Compared with inverter air conditioners, fixed-frequency air conditioners have the following disadvantages in terms of temperature control: because the frequency of fixed-frequency compressors is not variable, the temperature of the room rises or cools slowly at the beginning of the start-up of the air conditioner; The room temperature fluctuates greatly, and the user's comfort is poor. At the same time, the s

Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] refer to figure 1 , an embodiment of a control method for an air conditioner of the present invention is proposed. The control method of the air conditioner in this embodiment comprises the following steps:

[0034] Step S110, when the air conditioner is running for the first preset time, control the electronic expansion valve to operate at the opening degree B, and simultaneously detect the indoor return air temperature T1 of the air conditioner in real time;

[0035] After starting the air conditioner, the air conditioner will run in the corresponding set mode, for example, according to the control mode at the start, control the air conditioner to start up ...

Abstract

The invention discloses an air conditioner control method. The method includes the steps: when an air conditioner operates for a first preset time, controlling an electronic expansion valve to operate with opening B, and starting to detect indoor return air temperature T1 of the air conditioner in real time; according to an operation mode of the air conditioner, calculating a difference between the indoor return air temperature T1 detected in real time and target temperature Ts; in a refrigeration mode, enabling Delta T=T1-TS, and in a heating mode, enabling Delta T=Ts-T1; judging when the Delta T is within a range of [Tb, Ta], controlling the opening of the electronic expansion valve to be correspondingly regulated within a preset range value [B, C] according to changes of the indoor return air temperature detected in real time. The invention further discloses an air conditioner control device. By the method and device, the problem that a compressor of a fixed frequency air conditioner starts and stops frequently is solved, stepless regulation of refrigerating capacity or heating capacity is solved, and temperature fluctuation of a room with a variable frequency air conditioner is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] In the prior art, since the inverter air-conditioning system uses an inverter compressor, its control method is to control the temperature by changing the frequency of the inverter compressor according to the relationship between the ambient temperature and the set temperature; The fixed-frequency compressor is used, and its control method is to realize temperature control by starting and stopping according to the relationship between the ambient temperature and the set temperature. [0003] Compared with inverter air conditioners, fixed-frequency air conditioners have the following disadvantages in terms of temperature control: because the frequency of fixed-frequency compressors is not variable, the temperature of the room rises or cools slowly at the beginning of the start-up of the air condit...
