The lab is used for measuring the performanceof air conditioneraccording to ISO5151and ASHRAE16 standards. It measures various kinds of data including capacity, EER, COP,pressure and temperature of the Air-con. The lab consists of compartments (2 chambers), controlled-temperature air spaces (2 rooms), air handling unit, chillers, power panel, computer system and so on.
Room type Calorimeter Method: Using the adiabatic rooms as calorimeter, to evaluate the capacity of the UUT by measuring the heat input or removed from the calorimeter (electrical heat capacity or cooling capacity generated by a cooling coil) in order to maintain the rated working condition.
The method can be performed both in indoor and outdoor rooms of the calorimeter independently at the same time. The test result of the indoor room is considered as standard rating, and the outdoor can be regarded as the proof experiment.
