This is a recirculating air conditioning unit with transparent windows and a climatic chamber.

Inlet air is cooled by a refrigeration system, heated by a preheater, and added moisture or latent heat by a humidifier before entering the climatic chamber for demonstration of climate control. The air in the climatic chamber is further heated by a reheater and a humidifier before leaving. A fan installed after the preheater is used to circulate the air in the duct. Part of the air leaving the climatic chamber is vented and the remaining is recirculated and mixed with fresh air entering the inlet duct. The amount of air recirculation is controlled by ventilation dampers. Steam generator, compressor and condenser are installed underneath the duct.

Measuring instruments are provided for air flow rate, and temperature and humidity at various stages. Additional instruments are provided for measurement of refrigerant flow rate, temperature and pressure as well as power for the compressor and heat sources.

The unit is on steel frame on wheels.
