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.
