Product Description
ISO 15042 7.5HP Air-Enthalpy Energy Difference Test System
System Overview
This 7.5HP air enthalpy method test laboratory consists of indoor and outdoor side rooms designed to test air conditioner performance by measuring temperature, pressure, and electrical parameters. The system is suitable for testing window type, split type, and free-standing air conditioners, supporting both standard operating condition tests and expanded testing requirements for product sampling inspection and development.
System operation is controlled via programmable controller and HMI interface, with high-accuracy data collection and real-time data transfer to upper-level computers for processing, display, storage, and report generation.
Compliance Standards
Designed and tested according to:
  • ISO 5151:2010
  • ISO 15042:2017
Operating Principle
The test room adjusts air dry bulb and wet bulb temperatures through balanced temperature and humidity control. The refrigeration system provides continuous cooling and dehumidification, while temperature control meters regulate heater and humidifier output to achieve desired air conditions.
