CCF Calculator The Cooling Capacity Factor (CCF) is the ratio of total installed nameplate cooling capacity to critical load. This ratio should be about 1.2x or 120%. If the CCF is greater than 1.2 then it is very likely there are opportunities for right-sizing cooling capacity. In turn,...
The last thing we need to do is calculate the refrigeration capacity to handle this load, a common approach is to average the total daily cooling load by the run time of the refrigeration unit. For this I’m estimating the unit to run 14 hours per day which is fairly typical for this ...
If there are 10 cooling units installed with a rated capacity of 30 tons each and 7 are running, then the total running cooling capacity is 739 kW (7 x 30 tons = 210 tons, 210 tons x 3.52 = 739 kW). To convert tons to kW, multiply tons by the constant 3.52. For many reasons,...
The moisture holding capacity of air increases with temperature. Calculating Cooling Loads Calculating chiller and cooling tower refrigeration loads - in tons. Cooling Load - Convert between kW/ton to COP or EER Convert between cooling load units like kW/ton, COP and EER. Cooling Power vs. ...

Additionally, the new GVAF range features models specifically designed for data centre applications with capacity up to 1900kW. A stronger operating map is said to allow the units to deliver reliable cooling at 48°C ambient. The GVAF XSS, the smaller version of the Sintesis eXcellent is ...
That said, a typical price for custom 6 kW PSU’s in recent weeks is about $500/each, so we can just add this to our S19j Pro cost and bring it to $9000/machine. Running at 5500 W each, we need 1727 S19j Pro’s with custom PSU’s to fill our 9.5 MW available capacity. ...
