A versatile, floor-standing unit for the in-depth study of heating, ventilation, air conditioning and refrigeration (HVAC & R) systems. Facilitates the analysis of individual and combined psychrometric processes commonly used in air conditioning. Also allows study of the vapour compression refrigeration cycle, including the use of pressure enthalpy (P-h) charts.

Benchtop apparatus that allows students to investigate the fundamental principles of air conditioning, including enthalpy change in the air flow.
