Air Conditioner Electrical Safety Test Solution

Forecast for the Next Five Years (2025-2030)

With the global energy transformation and the popularization of smart homes, household air conditioners will develop in the direction of high efficiency, energy saving and intelligence. It is expected that the penetration rate of variable frequency technology will exceed 90% in 2030. At the same time, the demand for commercial air conditioners will surge due to emerging scenarios such as data centers and new energy charging stations, and the market size is expected to grow at an average annual rate of 8.5%. On the technical level, environmentally friendly refrigerant substitution, IoT integrated control and AI fault prediction will become core competitive points.

Core Requirements for Electrical Safety Testing of Air Conditioners

According to GB 4706.32-2024 and GB 5956-1991 standards, electrical safety testing must cover the following dimensions:

AC and DC withstand voltage test: The test voltage is twice the rated voltage (such as 250V equipment needs to withstand 500V), lasting 1 minute, focusing on detecting insulation weaknesses such as power input terminals and control modules.

Insulation resistance level: classified into basic insulation, double insulation, and reinforced insulation. The power frequency withstand voltage test needs to verify the heat resistance (≥180 minutes of fire resistance) and rust resistance of the material (in accordance with GB23864-2023).

Grounding resistance reliability: the support load must be ≥270kg (4-horsepower model), and the grounding resistance test accuracy requirement is ≤1% error.

Functional safety: including eight indicators such as leakage current, starting performance, and power control, which need to be eliminated through automated testing.

Electrical Safety Tester Selection Plan

Ainuo Instruments single/three-phase intelligent safety comprehensive analyzer AN1651TH series is an industry benchmark product that perfectly meets the testing needs of the air-conditioning industry:

Full-function Integration

A single device realizes eight tests such as AC/DC withstand voltage, insulation, grounding, leakage, power, and start-up, replacing the traditional multi-station combination solution.

Efficient parallel testing: synchronous detection of grounding and withstand voltage, leakage and power, completing all projects within 7 seconds, and increasing production line efficiency by 40%.

Intelligent Control

10-inch Android touch screen supports automatic scene recognition and intelligent matching of test parameters;

Built-in MES database docking module to achieve real-time upload and traceability of test data;

PLC/ALARM/REMOTE interface supports remote start and stop and abnormal alarm.

High-precision Guarantee

safety test error ≤1%, power test error ≤0.2%, meeting the strict requirements of GB 4706.32-2024 for performance indicators such as energy efficiency ratio and noise control.

Industry Application Value

This solution has been successfully applied to the production lines of leading companies such as Gree. Through barcode scanning to bind test data and fuse overload protection, the product pass rate is increased to 99.3%, and the annual average quality loss of enterprises is reduced by more than 10 million yuan. With the full implementation of GB/T 4706.32-2024 in 2026, the international certification of the AN1651TH series (IEC60335-2-40:2022 equivalent) will help companies quickly occupy the global market.
