About This Product
An air conditioning unit trainer lets students follow the processes that treat air: heating, cooling, dehumidifying and humidifying. Air is blown through the duct by the fan and passes each process in turn, and its state is read with wet and dry bulb thermometers before and after. Because the electrical power to each resistive load can be measured, students balance it against the change in air enthalpy and the mass flow, a standard psychrometry exercise. Upgrades can be added later to extend the experiments.
Frequently Asked Questions
Q1. What is in the duct of the Air Conditioning Unit?
The variable speed fan discharges into a 250 mm square duct fitted with a steam humidifier, electrical pre-heaters, a direct expansion cooling coil and dehumidifier, electrical re-heaters and an orifice plate for airflow measurement.
Q2. How is the air condition recorded?
Wet and dry bulb thermometers record the condition of the air before and after each process.
Q3. What can be balanced against the electrical power?
The electrical power to each resistive load can be measured and balanced against the air enthalpy change and mass flow.
