How we assess efficiency performance


Measurements of HVAC systems


Chiller performance testing

The cooling effect of refrigeration systems is measured in Tonnes of Refrigeration (TR)

A ton of refrigeration is defined as quantity of heat to be removed in order to form 1 ton of ice in 24 hours when the initial temperature of water is 0degC

1 TR = 3024 kcalhour = 351 kW = 12000 BTUhour
