Re-Circulating Air Conditioning Trainer.
Re-Circulating Air Conditioning Trainer
The re-circulating air conditioning trainer is designed to study
different air conditioning processes & performance analysis of
refrigeration cycle in Air Conditioning. The trainer consists of an air
conditioned chamber which houses the electric load bank. The heater load
is controlled by a dimmer. There are three ducts, each for Fresh Air,
Recirculated Air & Exhaust Air. Each duct is fitted with damper to
control amount of air flowing through it. In order to study
Humidification process a Steamer is also provided.
The refrigeration
system consists of a hermetically sealed compressor, air cooled
condenser, expansion device & finned tube evaporator. The evaporator
coil is fitted inside the inlet duct. Refrigerant R-22 is used in the
trainer.
The measuring instruments are provided to measure
Temperature & pressure of refrigerant cycle, Refrigerant Flow, Power
Supplied to compressor & Heater Load.
