The unit consists of ducting fitted  with various  air conditioning components. Airflow is

generated by an axial flow fan and in the airflow, heaters, cooling coil and steam humidifier

connection is  provided. Cooling circuit consists of  a  hermetic compressor; air cooled

condenser, thermostatic expansion valve and evaporator (i.e. cooling coil).

SPECIFICATIONS:

  1.  Cooling circuits - It consists of:

    a)  Hermetic compressor, having the capacity of 2/3 ton of refrigeration (approx.) 

using R-22 refrigerant.

    b)   Rotameter for liquid refrigerant flow measurement.

    c)  Pressure gauges

    d)  Prescott (i.e. high and low pressure cut-out).

    e)  Thermometers for temperature measurement at various points In the cycle.

    f)   Energymeter for compressor 

    g)  Condensate measuring arrangement.

  2.  Heating Circuit - Air heaters with input control provided with energymeter for input 

measurement. Maximum heating capacity 1 Kw.

  3.  Steam generator and injector for humidification of air. All above components are 

connected to a duct of size 200mm. X 200mm. in which airflow is generated by axial 

flow fan.

  4.  Floor space area about 3 m. X 2 m.
