Enthalpy Difference Testing Service for Electronics and Electrical Appliances

1. Capability Introduction

Jiayu Testing's 10HP Enthalpy Difference and Heat Pump Performance Comprehensive Laboratory is primarily used for testing air conditioning products up to 10HP and heat pump heating/cooling units up to 10HP/15HP. It meets the performance testing needs of products such as air-cooled air conditioners, heat fans, heating/cooling units, dehumidifiers, refrigerators, and freezers. This laboratory is specialized equipment that uses the enthalpy difference method to measure the cooling/heating capacity of air conditioners, while also measuring various performance parameters, including pressure and electrical parameters. It consists of two temperature-controlled environmental chambers: outdoor side A and indoor side B, two air handling units, a compressor condensing unit, an electrical cabinet, and a computer data acquisition system. Additionally, chamber B is equipped with one set of air volume measurement device.

Jiayu Testing provides more convenient and faster testing and certification services for a wide range of customers, ensuring various testing services and supporting the advancement of high-efficiency and energy-saving products.
