Air duct training system (AR – 009) is designed to introduce trainees to all main components of a central air conditioning system to simulate operation of central air conditioning. The educational unit allows trainees to monitor the temperature and humidity of the system on digital displays and investigate their effects as the system goes through a refrigeration or heating cycle.
- The trainer provides trainees a comprehensive understanding of central air conditioning unit components.
- The trainer demonstrates a central air conditioning unit that contains an air duct and a condensing unit in addition to a large operation and measurement panel.
- The air duct contains an evaporator, an evaporator fan, an electric heater and temperature and humidity sensors measure the temperature and humidity inside the duct.
- The duct is made of a transparent material to allow the various process to be visualized.
- The condensing unit includes a compressor, a condenser and an liquid receiver.
- The trainer operation unit contains trainer ON/OFF switch, emergency switch, humidifier operation button, Heating/Cooling mode selector, humidifier operation indication LED and high/low pressure alarm LED.
- The operation panel also includes high pressure switch and low-pressure switch and four pressure gauges, four temperature digital display, outlet temperature/humidity digital display, inlet temperature/humidity digital display and a power meter
- The operation panel also demonstrates a schematic diagram of the central air conditioning cycle with the psychometry chart.
- The two digital displays provide an accurate reading of inlet/outlet temperature and humidity.
- The pressure switch provides safety to the compressor which takes a protective action in case of any low/high pressure case occurs.
- The led indicator provides warning for any low/high pressure case occurred and provides an indicate for the humidifier state.
- The trainer allows trainees to observe the operation of the central air conditioning and investigate its parameters using sensors at different points throughout the cycle before and after the evaporator & before and after the condenser to measure refrigerant temperature and pressure and display it at the digital displays and pressure gauges at the operation panel.
- The refrigerant temperatures are measured by highly sensitive sensors and displayed on the four digital displays.
- The trainee can investigate how the central air conditioning can be changed from cooling mode to heating mode using Heating/Cooling mode selector,
- The humidifier is electrically operated by using its pushbutton on the control panel.
- This humidifier is used to control the relative humidity inside the duct so the trainees can increase the space moisture.
- The evaporator fan is used to circulate the air in the duct and dissipate the heat.
- The system temperature and humidity are dependent on the process cycle whether it works as cooling or heating and measured via sensors at two different points
