Fresh Air Enthalpy Difference Laboratory Gb/T21087-2020 Compliant Enthalpy Exchange Efficiency ±1%

Product Features

• Strong compliance with standards: fully meets the test accuracy and process requirements of GB/T 21087-2020, and is compatible with GB/T 18837 and ISO 16976 international standards.
• High-precision parameters: enthalpy exchange efficiency ±1%, air volume ±0.5%, temperature exchange efficiency ±1%, and core indicators are better than national standards.
• Sensor customization: optional international first-class brand sensors, support multi-brand comparison testing, and meet the credibility of high-end R&D data.
• Highly authoritative data: mandatory benchmarking with national laboratories before delivery, data deviation < 1%, directly used for certification declaration.
• Full-scenario coverage: simulate "severe cold - hot - high humidity" fresh air conditions to verify the extreme environmental stability of heat recovery and ventilation efficiency.
• Intelligent flow control: automatically generate efficiency curves, energy consumption reports, fault diagnosis, seamlessly connect to the MES system, and shorten the R&D cycle by 30%.

International reference standards
