AI Overview
Enthalpy difference method test equipment, or air conditioning enthalpy difference laboratories, are specialized facilities used to measure the cooling or heating capacity of HVAC systems by measuring the air properties at the inlet and outlet, usually compliant with standards like GB/T7725-1996. These labs typically consist of an "indoor + outdoor dual-chamber" system to simulate environmental conditions and calculate performance based on the enthalpy change and air mass flow rate.
