Oct 25, 2020 · These values will be put into the calculation. "A" = COP or EER at Capacity. "B" = COP or EER at 75% Capacity. "C" = COP or EER at 50% Capacity. "D" = COP or EER at 25% Capacity. So, when the chiller is running at , 75%, 50% and 25% we'll put in the EER that corresponds to that datapoint.

the time, at the part-load condition. The part-load efficiency is less than full-load because of transient losses, the need to reheat or recool ductwork when the system comes back on, operation of pumps and fans at full speed when not needed, throttling losses, etc. The system efficiency is derated to account for reduced part-load performance.

Dec 27, 2018 · If the quoted rate is $0.15/freight ton and the weight is 1,500 kilograms, or 1.5 tons, the freight rate calculation is as follows: 3.5 x 2.3 x 2.1 = 16.905 cubic meters. 16.905 CBM x $0.15 = $253.575. 1.5 tons x $0.15 = $22.5. The CBM rate is higher, meaning the freight rate of about $253 will apply to the shipment.
