Advanced HVACR Trainer

Learning Outcomes

With the Advanced HVAC & R Trainer learners will get hands-on experience using the Air Handling Unit and will develop skills like:

• Investigation of psychrometrics, definitions, relations, and psychrometric charts
• Real-time plotting of the psychrometric process
• Understanding of an air handling unit’s electromechanical components and their function
• Investigation of psychrometric processes including:
  • Single Stage Processes a) Sensible heating b) Steam humidification c) Sensible cooling d) Sensible and latent cooling and dehumidification e) Adiabatic humidification (evaporative cooling) Multiple Stage Processes (typical Examples) f) Heating and humidification g) Cooling, humidification and heating
• Observation of the effect of varying the fan speed, pump flow rates, and temperature settings for all the above psychrometric processes and combinations
• Calculation of the dew point
• Evaluation of the heat transfer across the water-to air heat exchanger and the log mean temperature difference (LMTD) driving force

Using the Water Chiller learners will study topics like:

• Understanding of refrigeration components and their function
• Investigation of the vapor compression refrigeration cycle including:
  • Real-time plotting of the P-h thermodynamic cycle for refrigerant R134
  • Calculation of superheat, subcooling, pressure ratio, saturated evaporating temperature, and saturated condensing temperature
  • Calculation of the isentropic efficiency of the compressor
  • Calculation of the heat balance, mass flow rate, and theoretical power of the saturation cycle
  • Calculation of the effect of varying the load on the refrigeration cycle
