FAQ:
1.How to calculate cooling capacity for chillers
Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-t2)/0.86
Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)
2.Cooling capacity unit conversion?
1 kcal／h ＝ 1.163W,1 W ＝ 0.8598 kcal／h；
1 Btu／h ＝ 0.2931W,1 W ＝ 3.412 Btu／h；
1 USRT ＝ 3.517 kW,1 kW ＝ 0.28434 USRT；
1 kcal／h ＝ 3.968 Btu／h,1 Btu／h ＝ 0.252 kcal／h；
1 USRT ＝ 3024 kcal／h,10000 kcal／h ＝ 3.3069 USRT；
3.This chiller could heat?
Yes,if heat recovery,only 30%. If fully heating,that is heat pump.
