Embodiment Construction

[0022] The specific implementation of the method for determining the initial frequency when the air conditioner compressor is restarted according to the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, in this embodiment, the specific implementation of the present invention will be described by taking the situation that the air conditioner is in the heating mode and the compressor is shut down and restarted during the control process using the incremental PID algorithm as an example.

[0024] After the air conditioner is turned on, the air conditioner detects the indoor temperature T 室内 , since in the PID control process, the calculation accuracy is 0.1 degree, therefore, let P n =(T 设定 -T 室内 )*10, where, T 设定 = Manually set temperature + set temperature correction value.

[0025] When entering heating mode for the first time, set P n Compared with heating first temperature difference and...

Abstract

The invention provides an air conditioner heating mode frequency control method. When a compressor of the air conditioner is in a heating mode, the compressor working frequency is corrected through a PID algorithm, and if the compressor is stopped, the compressor stopping starting initial frequency is determined through the outdoor environment temperature. By the aid of the method, the determination of the initial frequency can respond to temperature changes timely, and accordingly, the frequency can be improved and reduced effectively; the air conditioner running is stable, the indoor environment temperature fluctuation is small, the frequent starting and stopping of the compressor can be prevented, and the user experience is good; the running of the air conditioner is not affected by outside weather changes, frequency parameters can be adjusted according to weather conditions and are optimized through a large number of experiments, accurate initial frequencies can be given in special days, the frequency is adjusted according to the environment temperature, and accordingly, the air conditioner stable running can be guaranteed, and the temperature can be adjusted rapidly.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning control, and in particular relates to a method for determining the initial frequency of an air-conditioner when it is restarted after a compressor is shut down in a heating mode. Background technique [0002] The frequency conversion air conditioner can automatically adjust the operating frequency of the compressor according to the change of the indoor temperature, and then change the speed of the compressor to realize the adjustment of the operating state of the air conditioner. Inverter air conditioners have broad market prospects due to their advantages such as fast temperature adjustment, low noise, low energy consumption, and long service life. [0003] When the indoor temperature reaches the set temperature, the inverter air conditioner controls the compressor to stop. When the indoor temperature deviates from the set temperature, it restarts the compressor to make the indoor temper...
