Description
RA2 Computer Controlled Air Conditioning Unit Didactic Equipment Vocational Education Equipment Refrigeration Training Equipment

DESCRIPTION
The RA2 is a fully instrumented bench mounted air conditioning duct for teaching all aspects of air conditioning systems.
The RA2 duct is a bench top unit fabricated from clear acrylic and mounted on a painted mild steel support frame.
An axial fan moves air through the duct. Heating elements are used to heat the air. Humidification is provided by steam from the boiler.
The steam boiler for the humidifier, the compressor and condenser for the refrigeration system and the electronic control box are all mounted beneath the duct.
Temperature and RH sensors record the temperature and relative humidity at every stage of the operation.
The air flow is measured by an electronic sensor. The mains supply voltage is monitored in the equipment to allow calculation of effective heater powers.
TECHNICAL SPECIFICATIONS
Transparent duct: (200mm x 200mm) for process visibility
Pre-heater: 400w
Re-heater: 200w
Humidifier total volume: 5ltr
Humidifier unit: 2kW
Evaporator: 500w @20°c
Air velocity sensor hot film anemometer: 0-10m/s
Temperature / Relative humidity sensor x4: 10 to 100% relative humidity:
Duct inlet
Before the evaporator
After the evaporator
Duct outlet


EXPERIMENTAL CONTENT
Gain an in-depth understanding of an air conditioning system by demonstrating the effects of essential air conditioning processes: cooling, heating, humidifying and dehumidifying
Simulate different air conditioning environments and perform measurements to allow psychrometric data analysis
To investigate and understand the use of psychrometric charts, understand relative humidity (RH) measurements and the effect of temperature on RH and understand the Humidity Ratio
To investigate sensible heating of air in a duct
To investigate the humidification of air
To investigate the effect of vapour content and temperature on relative humidity
To investigate dehumidification of air by cooling
To investigate and understand the effect on enthalpy, understand relative humidity (RH) measurements and the effect of temperature on RH and understand the Humidity Ratio
