Air Conditioning Lab Unit | PolarX - 556
Product Overview
The Air Conditioning Lab Unit PolarX - 556 studies the effect of individual HVAC components on room air conditioning using an open air duct system. This Air Conditioning Lab Unit includes an air cooler, steam humidifier (500g/h, three stages), fan (810m³/h max), air preheater (2kW), and reheater (1kW), all individually switchable. Sensors monitor temperature (9 Type-k, -40~400°C), humidity (5 sensors, 0~100%), and refrigerant pressure/temperature before and after each stage. Optional LABVIEW-based DAQ software supports automated data transmission to a PC.

Construction and Design
The Air Conditioning Lab Unit PolarX - 556 uses an open air duct system incorporating an air cooler, steam humidifier, fan, air preheaters, and reheaters. All components can be switched on and off individually to study their individual and combined effects. Combined sensors for air humidity and temperature are placed before and after each stage, and a sensor monitors the pressure and temperature of the refrigerant. Air flow is determined using differential pressure measurement via an inclined tube manometer. The system runs on R134a refrigerant, which is CFC-free.
Software
PolarX - 556 (optional). A DAQ software package, specially designed in National Instruments LABVIEW environment, measures and calculates the results of the apparatus. The software is optional. When the software is used, a set of electronic sensors is included. The software can be run on any Windows environment.
