Embodiment Construction

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0046] figure 1 It is the control method of the inverter air conditioner described in Embodiment 1 of the present invention.

[0047] Such as figure 1 As shown, a control method of an inverter air conditioner includes the following steps:

[0048] Step S1, collecting indoor ambient temperature;

[0049] Step S2, calculating the difference between the indoor ambient temperature and the indoor set temperature; wherein the indoor set temperature can be set according to demand through the remote control of the inverter air conditioner;

[0050] Step S3, adjusting the operating frequency of the inverter compressor or the rotational speed of the DC fan of the indoor unit according to the difference between the indoor a...

Abstract

The invention relates to a variable frequency air conditioner control method and system. The method includes the steps that 1, the indoor environmental temperature is collected; 2, the difference value between the indoor environmental temperature and a set indoor temperature is worked out; and 3, the operating frequency of an inverter compressor or the rotation speed of a direct-current fan of an indoor unit is adjusted according to the difference value between the indoor environmental temperature and the set indoor temperature. The system comprises an indoor environmental temperature sensor, a controller, the inverter compressor and the direct-current fan of the indoor unit, wherein the indoor environmental temperature sensor is used for collecting the indoor environmental temperature; the controller is used for working out the difference value between the indoor environmental temperature and the set indoor temperature, and adjusting the operating frequency of the inverter compressor or the rotation speed of the direct-current fan of the indoor unit according to the difference value between the indoor environmental temperature and the set indoor temperature. By means of the variable frequency air conditioner control method and system, frequent starting of the inverter compressor can be reduced or avoided, the service life of the inverter compressor is prolonged, a stable indoor environmental temperature is maintained, the comfort degree is improved, and the operative reliability of an air conditioner is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method and system for an inverter air conditioner. Background technique [0002] Generally, when the air conditioner is in cooling or heating operation, when the indoor ambient temperature reaches the preset temperature, the inverter compressor will run at the lowest frequency until the ambient temperature is lower than the set temperature during cooling, or When the ambient temperature is higher than the set temperature, the outdoor inverter compressor will be stopped directly to meet the customer's temperature requirements, that is, comfort requirements. [0003] However, the airtightness of people’s living space is getting better and better. When the inverter air conditioner starts to run for a longer and longer time, even the inverter air conditioner will stop when it reaches the temperature. This is also a problem for the service life of the inverter compr...
