◉ Capability introduction
Jiayu Testing Enthalpy Difference and Heat Pump Performance Comprehensive Laboratory mainly meets the performance testing needs of air-cooled cold air conditioners, hot air fans, chillers, heat pumps, dehumidifiers, refrigerators, and other products. This laboratory is a specialized equipment that uses enthalpy difference method to measure the cooling/heating capacity of air conditioners. At the same time, it can also measure various performance parameters of air conditioners, including pressure and electrical parameters. It consists of two temperature controlled environmental compartments, one on the outer side A and one on the inner side B. It is equipped with two sets of air handling units, a compression condensing unit, an electrical cabinet, and a computer data acquisition system. In addition, one set of air volume measurement device is installed in the environmental compartment B.
Jiayu Testing provides customers with more convenient and fast testing and certification services, guarantees various testing services, and helps products become more efficient and energy-saving.
