Description of Recirculation Air Conditioning Unit With Climatic Chamber for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers

Recirculation Air Conditioning Unit With Climatic Chambe is a recirculating air conditioning unit with transparent windows and a climatic chamber. Inlet air is cooled and preheated by a heater and 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 heater and a humidifier before leaving. A fan after the preheater circulates the air. Part of the air leaving the climatic chamber is vented and the remaining is recirculated with make up fresh air entering the inlet duct. The amount of air recirculation is controlled by ventilation flaps. Steam generator, compressor and condenser are 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.
