Embodiment Construction

[0031] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See figure 1 , which is a flow chart of an embodiment of the inverter air conditioner control method based on the present invention.

[0033] Such as figure 1 As shown, the embodiment implements the inverter air conditioner control method, specifically, the specific process of realizing the wall-mounted inverter air conditioner refrigeration control method is as follows:

[0034] Step 101: The air conditioner is turned on, and the compressor is controlled to run.

[0035] 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.

[0036] Step 102: Judging whether the running time of the compressor reaches the set running time. If yes, go to...

Abstract

The invention discloses a variable frequency air conditioner control method. The variable frequency air conditioner control method comprises the following steps: an air conditioner is started to operate a refrigerating mode; after the operation time of a compressor of the air conditioner reaches the set operation time, a present indoor temperature detected by an indoor temperature sensor 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 to obtain an indoor temperature difference; the room-temperature PID operation is performed according to the indoor 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; and a coil target temperature adopted in the disc temperature PID control is determined according to a real-time indoor humidity. 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, and realizes more reasonable control.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for controlling 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. [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 target temperature of the coil adopts a fixed value, which is generally a fixed temperature value solidified in the storage of the air conditioner. In the actual use process, there is often a phenomenon: in the case of keeping the user-set te...
