Air Conditioning Enthalpy Difference Test Room International Standard Air Conditioning Performance Test Equipment

Air Conditioning Enthalpy Difference Test Room International Standard Air Conditioning Performance Test Equipment

Product Introduction

As the core platform for air conditioning performance testing, AEEDL-001 uses the air enthalpy difference method to achieve multi-dimensional parameter measurement: indoor and outdoor cabin simulation - 20℃~50℃ temperature range, 10%~95% RH humidity, ±0.1℃ temperature control accuracy meets the strict requirements of GB/T7725 for the enthalpy difference method. The equipment is equipped with 6 R32 infrared detectors (3 inside and 3 outside), real-time monitoring of 0~100% LEL concentration, two-level early warning linkage ventilation, power off and fire emergency lighting, to ensure the safety of testing flammable and explosive refrigerants such as R32/R290. The modular design is compatible with split-type, multi-split and other models, supports maximum/minimum operation of cooling/heating, freezing/condensation and other extreme working conditions, covers the entire process from R&D to mass production. Air conditioning performance evaluation, data can be directly used for GB, ISO, ASHRAE and other domestic and foreign certifications.

Product Features

• High-precision measurement: Inlet air dry/wet bulb temperature ±0.10℃ control, relative humidity ±2% RH measurement, meeting the accuracy requirements of international standards for enthalpy difference method.
• Explosion-proof safety system: Two-level warning (10%/20% LFL) linkage ventilation, power off, 10-minute rapid dilution of leaked refrigerant, suitable for testing high-risk refrigerants such as R32/R290.
• Full-condition simulation: -20℃~50℃ wide temperature range (optional -40℃), 10%~95% RH humidity, support maximum/minimum operation, freezing/condensation and other extreme conditions.
• Intelligent linkage control: Fresh air/exhaust damper, explosion-proof fan and alarm system automatically respond to ensure safe and controllable gas concentration in the cabin.
• Anti-static design: Independent grounding (<1.0Ω), anti-static wheel and rubber seal, eliminate hidden dangers of static sparks, suitable for sensitive electronic testing.
• International standard compatibility: Supports GB/T, ISO, JIS, ASHRAE and other systems, and the output data is directly used for domestic and foreign certification applications.

International reference standards
