Problems solved by technology

After the traditional air conditioner is turned on, in order to improve the heat transfer performance of the heat exchanger and make the whole room quickly reach the room set temperature, the internal fan and compressor run at a higher frequency. Reduce the frequency of the compressor, but the speed of the internal fan is still running at the current high speed, which not only makes people have a strong sense of blowing, but also increases the cooling and heating load of the room and increases the energy consumption of the air conditioner

Embodiment 1-1

[0054] Such as figure 1 Shown is a logic diagram of the air supply control method in the first air conditioner room in the heating mode. The following will be based on figure 1 Specifically, the method for controlling the air supply of the first air conditioner in the heating mode.

[0055] When the air conditioner is in the heating mode, the method for controlling the indoor air supply of the air conditioner includes the following steps:

[0056] S0: The temperature sensor in the air conditioner detects the actual temperature T of the room e ;

[0057] S1: Judging the actual temperature T of the room e with room set temperature T s Whether the difference is greater than or equal to the first heating set value ΔT 1 ;

[0058] S2: Determine the following air supply modes based on the judgment result of step S1:

[0059] When T e -T s ≥ΔT 1 , the judgment result of step S1 is "yes", adjust at least the following three parameters: compressor frequency f, internal fan s...

Embodiment 1-2

[0069] Such as figure 2 Shown is a logic diagram of the air supply control method in the second air conditioner room in cooling mode. The following will be based on figure 2 The air supply control method of the second air conditioner in cooling mode will be specifically described.

[0070] When the air conditioner is in cooling mode, the method for controlling indoor air supply of the air conditioner includes the following steps:

[0071] S0: The temperature sensor in the air conditioner detects the actual temperature T of the room e ;

[0072] S1': Judging the room set temperature T s and actual room temperature T e Whether the difference is greater than or equal to the first cooling set value ΔT 1 ';

[0073] S2': Determine the following air supply modes based on the judgment result of the step S1':

[0074] When T s -T e ≥ΔT 1 ', the judgment result of step S1 is "Yes", adjust at least the following three parameters: compressor frequency f, internal fan speed V...

Embodiment 2

[0092] This embodiment is based on the method of adjusting parameters in Embodiment 1: that is, reducing the frequency f of the compressor, reducing the speed V of the internal fan, and increasing the cross-sectional area F of the air outlet of the air conditioner for further improvement and optimization.

Abstract

The invention relates to a control method for indoor air supply of an air conditioner. When the air conditioner is in a refrigeration mode, the control method for indoor air supply of the air conditioner comprises the following steps that S1', whether Ts-Te is larger than or equal to delta T1' or not is judged; S2', when the Ts-Te is larger than or equal to delta T1', at least the following threeparameters including the compressor frequency F, the inner fan rotating speed V and the air outlet cross section area F of an air conditioner air outlet are adjusted, and the air conditioner enters alow-disturbance air supply mode; and if the Ts-Te is not larger than delta T1', the original normal air supply mode of the air conditioner is maintained; S3', when the air conditioner enters the low-disturbance air supply mode, whether Te-Ts is larger than or equal to delta T2' or not is judged; and S4', when the Te-Ts is larger than or equal to delta T2', the air conditioner exits from the low-disturbance air supply mode and returns to the original normal air supply mode; and if the Te-Ts is not larger than delta T2', the air conditioner continues to keep running in the low-disturbance air supply mode. After the room where the air conditioner is positioned reaches the room set temperature, the air conditioner implements the low-disturbance air supply mode, the air supply intensity of theair conditioner to people is reduced, the blowing feeling of the air conditioner to people is reduced, and the comfort of the air conditioner in the using process is improved.

Description

technical field [0001] The invention relates to a method for controlling indoor air supply of an air conditioner, an air conditioner and a control system thereof, and the invention belongs to the technical field of air conditioners. Background technique [0002] In the prior art, whether the air conditioner is in cooling or heating mode, before the room where the air conditioner is located has not reached the set temperature of the room, the internal fan runs at a relatively high speed. The heat exchange of indoor air is beneficial to the heat exchange process, but when the air output of the internal fan is large, the indoor air flow is greatly disturbed. [0003] When the set temperature of the room is reached, the purpose of the air conditioner is to maintain the set temperature of the room. If the air outlet speed of the indoor unit of the air conditioner is still high at this time, it will undoubtedly enhance the air flow disturbance around the wall of the indoor heat ex...
