Air Conditioning Enthalpy Difference Test Room Multi-Refrigerant Air Conditioning Performance Test System

Air Conditioning Enthalpy Difference Test Room Multi-Refrigerant Air Conditioning Performance Test System

Product Introduction

AEEDL-006 consists of an indoor test chamber, an outdoor simulation chamber, an air handling unit, and an intelligent measurement and control system:

• Dual-chamber environmental reproduction: indoor 10~50℃ (simulating user end), outdoor -20~60℃ (simulating extreme climate), 35~90% RH humidity covers the rainy season and dry season scenes.
• Multi-parameter synchronous measurement and control: 20-channel thermocouples (±0.1℃) monitor the temperature field, WT333E power meter (±0.2%) collects electrical parameters, and 2-way refrigerant pressure sensors capture compressor characteristics;
• Flexible refrigerant adaptation: supports R22/R410a/R32/R290/R134a, adapting to the iteration requirements of environmentally friendly refrigerants.
• Automated process: The computer joint control system automatically collects data, generates energy efficiency curves and fault diagnosis reports, and connects to the MES system, improving test efficiency by 50%.

Product Features

• Multi-refrigerant compatibility: covers low GWP refrigerants such as R32/R290, conforms to the "dual carbon" trend, and supports future refrigerant upgrades.
• Ultra-wide temperature range verification: outdoor - 20℃ (extremely cold heating and defrosting), 60℃ (hot summer cooling and anti-freezing), verifying reliability under extreme working conditions.
• Micron-level measurement and control: 20-channel thermocouples (±0.1℃), WT333E power meter (±0.2%), air volume ±1% accuracy, data comparison deviation with national laboratories < 1.5%.
• Customized expansion: air volume, temperature range, and number of sensor channels support customization, and adapt to non-standard models (such as cylindrical cabinets and ultra-thin wall-mounted units);
• Dual standard compliance: meets both GB 7725-2010 (domestic) and ISO 5151/13253 (international), and the certification data is "collected once and used globally".
• Intelligent unmanned: 7-inch touch screen + remote IoT monitoring, supporting 7×24h Unattended testing, fault alarm + preventive maintenance.

International reference standards

• GB 7725-2010 Enthalpy difference method test process for room air conditioners, performance parameters (cooling/heating, energy efficiency) measurement accuracy requirements.
• ISO 5151-2017 Non-ducted air conditioner/heat pump performance test and rating (including low load, extreme temperature and humidity conditions).
• ISO 13253-2017 Supplements air conditioner performance test methods under special environments (such as high humidity, dust) to enhance data reliability.

Product use

• R&D end: Optimize air conditioner energy efficiency ratio (COP/SEER), low temperature defrosting ability, high temperature heating and ventilation stability.
• Quality inspection end: Pre-shipment performance consistency test (cooling/heating, air volume, static pressure), fault simulation (freezing, condensation).
• Certification end: Support China Energy Efficiency Label, EU ErP, US DOE certification, and accelerate overseas market access.
• Teaching end: University HVAC system thermodynamics experiment, intelligent control algorithm verification, refrigerant characteristics research.
