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, 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:

[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: Judging whether the air conditioner enters room temperature PID control. If yes, go to step 10...

Abstract

The invention discloses a variable-frequency air conditioner control method which comprises the following steps: powering on an air conditioner and enabling the air conditioner to run in the refrigeration mode; when the air conditioner is under the room temperature PID control, acquiring the current indoor temperature detected by an indoor temperature sensor and taking the acquired current indoor temperature as first room temperature; taking the difference between the first indoor temperature and the set compensation temperature as second indoor temperature; calculating the temperature difference between the second indoor temperature and the current indoor target temperature to acquire indoor temperature; carrying out indoor temperature PID calculation according to the indoor temperature, so as to acquire first target frequency; comparing the second indoor temperature with the set comfortable temperature; according to the comparison result, determining whether the room temperature PID control or the dual PID control is executed, wherein the dual PID control comprises the coil temperature PID control; and determining the coil pipe target temperature adopted in the coil temperature PID control according to the real-time indoor humidity. Through application of the variable-frequency air conditioner control method disclosed by the invention, both the indoor temperature regulation comfort and the low-power-consumption energy saving property of the air conditioner can be taken into account, thereby achieving the 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...
