Rotary Dehumidifier Test Center
This test center collects operating parameters through sensors to accurately evaluate the dehumidification capacity and operating status of rotary dehumidifiers. Test data can be accessed via mobile devices around the clock, providing valuable reference for further research on fault diagnosis and performance evaluation.
Chiller Unit Performance Test Center
This center supports performance testing for chiller units as well as water-source and ground-source heat pumps. It can simulate year-round operating conditions, with a maximum single-unit testing capacity of 1200 kW.
100HP Environmental Simulation Laboratory
This laboratory supports testing for hot and cold water units, direct expansion units, modular air handling units, and fan coil units. It is also capable of testing explosion-proof units. The laboratory can simulate year-round operating conditions, with a maximum single-unit testing capacity of 300 kW.
Environmental Simulation Enthalpy Difference Laboratory
This laboratory can simulate ambient temperatures ranging from -30°C to 50°C. It is used to test dehumidifier performance under different climate conditions, while the central monitoring room tracks operating parameters and system status in real time. This provides an important basis for ensuring stable and reliable dehumidifier operation.
