Embodiment Construction

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] See figure 1 , which is a flow chart of an embodiment of the inverter air conditioner control method based on the present invention.

[0032] Such as figure 1 As shown, this embodiment realizes the control method of the inverter air conditioner, specifically, the specific process of realizing the refrigeration control method of the wall-mounted inverter air conditioner is as follows:

[0033] Step 101: The air conditioner is turned on, and the compressor is controlled to run.

[0034] After the air conditioner is turned on, it will control the operation of the compressor according to the user-set or default operation mode and operation parameters, and according to the predetermined control program.

[0035] Step 102: Determine whether the air conditioner enters room temperature PID control. If yes...

Abstract

The invention discloses a variable frequency air conditioner control method. The variable frequency air conditioner control method comprises the following steps: when an air conditioner enters room-temperature PID control, a present indoor temperature is obtained as a first indoor temperature; a difference value between the first indoor temperature and a set compensation temperature serves as a second indoor temperature; a temperature difference between the second indoor temperature and a present indoor target temperature is calculated; the room-temperature PID operation is performed according to the temperature difference to obtain a first target frequency; the second indoor temperature is compared with a set comfortable temperature; the room-temperature PID control or the dual PID control including the disc temperature PID control is performed according to the compared result; a coil target temperature adopted in the disc temperature PID control is determined according to a real-time indoor humidity; in the room-temperature PID control or dual PID control process, a human body temperature is detected; when the human body temperature is abnormal, the present indoor target temperature is increased. The variable frequency air conditioner control method can give consideration to indoor temperature adjusting comfort of an air conditioner and low-power consumption energy conservation of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method for an inverter air conditioner. Background technique [0002] In the hot summer, many people cannot do without the air conditioner all day and all night. However, blowing air conditioners for a long time has many harms to the human body, and it is easy to get air conditioner diseases. In addition, if there is a fever or the phenomenon of pushing the quilt during sleep at night, the user will not be able to find out in time. In a cold wind environment, it is more likely to catch a cold, which is especially serious for children. [0003] In order to solve the uncomfortable problem caused by cold air blown out by refrigeration, the control method of controlling the operating frequency of the compressor can be based on the coil temperature of the indoor heat exchanger as the control target. In the existing coil temperature control process, the...
