HVAC-R Experimental Equipment
The air conditioning systems widely used in various industries, as well as for improving living standards, not only maintain comfort in daily life but also refer to the control of industrial process environments. The EC1550V is a device equipped with an HVAC-R air conditioning system that demonstrates the thermodynamic processes of heating and humidifying, cooling, and refrigeration within ducts.
The portable experimental device, using R134a as the refrigerant and equipped with movable casters, draws air from the intake grille on the left side of the duct, passing through a manual opening and closing damper, a variable speed axial fan, a primary heater, a steam humidifier, a heat exchanger (water-cooled), a water sprayer, a mist eliminator, and a secondary heater, before being discharged from the exhaust grille on the right side of the duct.
It digitally displays the temperature and humidity for each air conditioning process, the air velocity at one location within the duct, the refrigerant pressure (high and low), temperature, refrigerant flow rate, and the power consumption of the compressor. The chilled water tank, temperature-controlled by the refrigeration system, sends chilled water to the heat exchanger in the duct via a variable speed pump, and the inlet and outlet temperatures and flow rates of the heat exchanger are displayed digitally. The primary and secondary heaters, controlled by PID, can be compared in performance with different power inputs.
