Instrumented Thermodynamic Water Heater

This bench allows the study of the operation of a thermodynamic water heater with a heat pump. Educational Objectives: Visualize and identify system components. Adjust a thermodynamic water heater. Learn about Instrumented Thermodynamic Water Heater specifications for optimal educational outcomes.. Perform an energy balance using parameter measurements: energy consumed, temperatures and flow rates on water and air. Understand a refrigeration circuit through pressure and temperature measurements. Learn about Instrumented Thermodynamic Water Heater manufacturers for optimal educational outcomes..

The unit is based on a thermodynamic water heater. It has been modified for better understanding by students.
