AIR CONDITIONING TRAINER GENERAL CYCLE TYPE : PSAW-204RA
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). Measurements of various parameters Torn cooling cycle and
heating cycle are provided and students can easily visualize and understand the
basic principles of air conditioning.
