Problems solved by technology

Poor adaptability during the operation of the air conditioner
For example, when the ambient temperature drops, the operating parameters of the air conditioner, such as the fan speed of the outdoor unit and the frequency of the compressor, are still operating according to the current state, resulting in an increase in energy consumption of the air conditioner, which is not conducive to energy conservation and environmental protection

Embodiment 1

[0044] At the first sampling time point t 1Obtain the first outer coil temperature T on 外盘1 35°C, the first inner coil temperature T 内盘1 is 13°C. At the second sampling time point t 2 Obtain the second outer coil temperature T on 外盘2 38°C, the second inner coil temperature T 内盘2 is 14°C. The first sampling time point t 1 and the second sampling time point t 2 The difference is 60s.

[0045] The degree of change of the temperature of the second outer coil relative to the temperature of the first outer coil ΔT 外盘 is a positive value, the degree of change of the temperature of the second inner coil relative to the temperature of the first inner coil ΔT 内盘 is a positive value. Therefore, changing the speed of the outdoor fan from the first speed R 1 into the fourth speed R 4 ; where the fourth speed R 4 than the first speed R 1 50RPM higher. Change the compressor frequency from the first frequency F 1 becomes the second frequency F 3 , the first frequency F 1 3 ....

Embodiment 2

[0047] At the first sampling time point t 1 Obtain the first outer coil temperature T on 外盘1 45°C, the first inner coil temperature T 内盘1 is 13°C. At the second sampling time point t 2 Obtain the second outer coil temperature T on 外盘2 45°C, the second inner coil temperature T 内盘2 is 14°C. The first sampling time point t 1 and the second sampling time point t 2 The difference is 60s.

[0048] The degree of change of the temperature of the second outer coil relative to the temperature of the first outer coil ΔT 外盘 is zero, the degree of change of the temperature of the second inner coil relative to the temperature of the first inner coil ΔT 内盘 is a positive value. Therefore, and the expansion valve opening is changed from the first opening E 1 becomes the second opening degree E 2 , where the first opening E 1 2 . The value of the constant P is 2, the first opening E 1 for 150, E 2 =E 1 +E 1 *ΔT 内盘 *P / (t 2 -t 1 )=150+150*(14-13) / 60*2=154.

Abstract

The present invention provides an air conditioner control method, the control method at the first sampling time point t 1 Above, collect the temperature of the inner coil and the outer coil of the air conditioner to obtain the first outer coil temperature T 外盘1 and the first inner coil temperature T 内盘1 ; at the second sampling time point t 2 Above, collect the temperature of the inner coil and the outer coil of the air conditioner to obtain the second outer coil temperature T 外盘2 and the second inner coil temperature T 内盘2 ;according to the degree of change ΔT of the temperature of the second outer coil relative to the temperature of the first outer coil 外盘 and the degree of change in temperature of the second inner coil relative to the temperature of the first inner coil ΔT 内盘 , adjusting the operating parameters of the air conditioner, where the operating parameters are at least one of the outdoor fan speed, expansion valve opening and compressor frequency. The invention can adjust the operating parameters of the air conditioner accordingly, the selection of the adjustment parameters and the size of the adjustment range.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and the air conditioner. Background technique [0002] With the development of science and technology and the improvement of people's living standards, air conditioners have become an indispensable household appliance in people's lives. In recent years, due to its powerful cooling effect and novel appearance, vertical air conditioner indoor units have been recognized by consumers. [0003] With the increasingly mature technology and increasingly fierce competition in the field of home appliances, consumers have higher and higher quality requirements for air conditioners. Air conditioners not only need to have good cooling effect and aesthetics, but also need to have multiple functions or advantages such as energy saving, low carbon and intelligent operation. [0004] Among them, the air conditioner is affected by the ambient temperatur...
