Embodiment 1

[0039] Such as figure 1 As shown, the method for preheating the compressor of the air-conditioning unit of the present invention, after the compressor is preheated, uses a time comparison method to determine whether the compressor needs to be preheated again after the compressor is abnormally or artificially powered off.

[0040] First turn on the power supply, the main control device connects the voltage to the compressor to preheat, record the current preheating time, and the main control device accumulates the preheating time of the compressor, and the duration of the compressor preheating when it is powered on After more than 8 hours, the preheating of the compressor is completed. After the preheating is completed, enter the debugging process of the compressor. If there is an abnormal power failure or artificial power failure during the debugging process, record the current power failure time T1. After the compressor solves the problem and powers on again, record it again....

Embodiment 2

[0057] Such as Figure 4 As shown, a processing device 100 for compressor preheating of an air-conditioning unit includes a first timing module 110 , a second timing module 120 , a time calculation unit 130 and a determination unit 140 .

[0058] in:

[0059] The first timing module 110 is used to record the power-off time T1 during power-off during the commissioning process after the air-conditioning unit is preheated for a preset preheating time;

[0060] The second timing module 120 is used to record the re-power-on time T2 when the power is turned on again after power-off;

[0061] The time calculation unit 130 is used to calculate the power-down time according to the power-off time T1 and the power-on time T2 again;

[0062] The determining unit 140 is configured to compare the power-off time with a preset warning time T3 and then determine the reheating mode of the compressor of the air conditioner unit.

[0063] After the air conditioner unit is powered off, the first ...

Abstract

The invention discloses a preheating processing method and device for an air conditioning unit compressor. The method comprises the following steps that after an air conditioning unit is preheated for preset preheating time, the power failure moment is recorded during power failure in the starting-up adjusting process; when the air conditioning unit is powered on again and started after power failure, the power recovery moment is recorded, and the power failure time is worked out according to the power failure moment and the power recovery moment; after the power failure time is compared with the preset warning time, the recovery preheating mode of the air conditioning unit compressor is determined. According to the method and device, on the basis that the preheating effect of the compressor is guaranteed, and the installing and debugging are not affected, the preheating time of the compressor does not need to be spent again, the debugging efficiency is improved, and the time cost is saved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a processing method and device for preheating compressors of air conditioning units. Background technique [0002] For the installation and commissioning of existing air conditioners, in order to prevent damage to the compressor and prolong its service life, each manufacturer will require the compressor to preheat for a period of time (usually 8 hours) before allowing the compressor to start and debug. The traditional method has the following defects: [0003] 1. After the preheating of the compressor is completed, most of the abnormal power failures or abnormalities in the processing process need to be re-powered off to solve, and then need to be preheated again after power-on; [0004] 2. The compressor commissioning personnel need to wait again. [0005] The traditional debugging method has low debugging efficiency and high time cost. Contents of the invention [0006] Base...
