ISO 5151 Air Enthalpy Method Calorimeter 60K BTU Dual Station

Air Enthalpy Method Calorimeter – ISO 5151 60K BTU Dual Chamber Performance Testing System

The Air Enthalpy Method Calorimeter is a high-accuracy environmental test chamber system engineered by KingPo for comprehensive performance evaluation of air conditioners according to ISO 5151 and related standards. It consists of two independent chambers: indoor side (Chamber A) and outdoor side (Chamber B), enabling precise measurement of cooling capacity, heating capacity, airflow, dehumidifying capacity, input power, EER/COP, voltage, current, and frequency under controlled temperature and humidity conditions.

The dual-station design allows simultaneous testing of two single-phase units (≤30K Btu/h each, total ≤60K Btu/h) or single unit testing up to 60K Btu/h. It supports split-type, window-type, freestanding, ceiling cassette, ducted, and inverter air conditioners, making it ideal for R&D validation, type approval, production sampling inspection, and energy labeling compliance.
