Problems solved by technology

[0002] The existing on-line detection method for the production of air conditioner outdoor units usually installs an indoor unit that matches the outdoor unit in the testing room, connects the outdoor unit and the indoor unit with pipes, turns on the heating or cooling mode of the indoor mechanism, and completes the test. Then the refrigerant is recycled to the outdoor unit; the shortcomings and defects of this detection method are 1. The indoor unit needs maintenance, regular vacuuming, leak detection, etc., and there are many styles and models of outdoor units produced by a production line, which requires a testing room Different types of indoor units are configured, and the testing room takes up a lot of space; 2. The running current of the outdoor unit is high, and the power load of the testing room is large; 3. It takes a long time to collect the refrigerant. The refrigerant can only be collected after the fault is solved. Remove the connecting pipe and remove the outdoor unit. Otherwise, the pipe cannot be disassembled and the testing platform will be occupied for a long time. Because the shared indoor units are mixed together, there is a certain uncontrollable risk of mixing different brands of compressor refrigeration oil together. In addition, the oil discharge volume of each outdoor unit is different, and the final oil volume of each outdoor unit is somewhat different; 5 , The detection time is relatively long, and it takes about 18-20 minutes for a machine, which cannot meet the production beat demand

Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific embodiment:

[0014] Refer to attached figure 1 As shown, this embodiment is an online detection method for an outdoor unit of an air conditioner, which includes the following steps: S1. Directly short-circuit the liquid outlet pipe and the air return pipe of the outdoor unit of the air conditioner through a preset short-circuit tooling, thereby forming a refrigerant cycle The loop, wherein, specifically, the shorting tool is a copper pipe, and the two ends are directly connected to the liquid pipe stop valve and the gas pipe stop valve of the outdoor unit of the air conditioner to realize a closed circulation loop formed by the outdoor unit of the air conditioner and the shorting tool;

[0015] S2. Control the power-on and start-up of the outdoor unit of the air conditioner, and control the main control board of the outdoor unit to energize each load and each valve in turn and detect the...

Abstract

The invention discloses an online detection method for the outdoor unit of an air conditioner. The online detection method comprises the following steps: S1. the liquid outlet pipe and the return pipeof the outdoor unit of the air conditioner are shorted to form a refrigerant circulation loop; S2. the outdoor unit of the air conditioner is controlled to be powered on and started and the start-upof each load and each valve is controlled; S3. the outdoor unit of the air conditioner is controlled to stop for a preset first stop length; S4. the outdoor unit of the air conditioner is controlled to operate in a heating mode, the compressor operates at a low frequency and the fan operates at a low windshield for the preset test operation length and the operating parameters of the outdoor unit of the air conditioner are obtained in real time; S5. the outdoor unit of the air conditioner is controlled to stop for the second stop length; and S6. the outdoor unit of the air conditioner is controlled to enter the refrigeration mode, the compressor operates at high frequency, the fan operates at high windshield and the operating parameters of the outdoor unit of the air conditioner are obtained in real time, and the compressor is controlled to switch to the low frequency operation after operating the preset test length and the outdoor unit of the air conditioner is controlled to stop and end the test after re-running for the preset test length.

Description

technical field [0001] The invention relates to the technical field of air conditioner outdoor unit production, in particular to an online detection method for an air conditioner outdoor unit. Background technique [0002] The existing on-line inspection method for the production of air conditioner outdoor units usually installs an indoor unit that matches the outdoor unit in the inspection room, connects the outdoor unit and the indoor unit with pipes, turns on the heating or cooling mode of the indoor mechanism, and completes the inspection. Afterwards, the refrigerant is recycled to the outdoor unit; the shortcomings and defects of this detection method are 1. The indoor unit needs maintenance, regular vacuuming, leak detection, etc., and there are many styles and models of outdoor units produced by a production line, which requires a testing room Different types of indoor units are configured, and the testing room takes up a lot of space; 2. The running current of the ou...
