Air-to-Water Heat Pump Operation Training Bench Unit

An Air-to-Water Heat Pump Operation Training Bench for studying the use of heat pumps to transfer heat from one source at a certain temperature to another source at a higher temperature.

The Air-to-Water Heat Pump Operation Training Bench Unit  is designed to allow students to gain both practical and theoretical knowledge of the operation of heat pumps.

The Air-to-Water Heat Pump Operation Training Bench Unit has been designed and manufactured to incorporate all current safety standards.

The refrigerant used complies with anti-pollution legislation.

Experiments

• Studying the operation of a heat pump
• Plant start-up and system monitoring using the protection and safety devices incorporated into the training bench

Analysing system behaviour and reactions with the variation of:

• Thermostatic valve superheat
• Air flow rate at the evaporator
• Water temperature in the tank

Plotting the refrigeration cycle on a p-h diagram

• Obtaining data readings and calculation of:
• Heat balances for the evaporator, condenser and compressor
• Refrigerant mass flow
• Ideal and actual coefficient of performance (C.O.P.)
• Volumetric compression efficiency
