How To Compute Chiller Efficiency Hvac Master Youtube The amount you can save really depends on how much fouling has built up on the surfaces. cleaning heavily fouled chiller could lead to an energy saving of up to 10% where as a lightly fouled chiller would see 1 3% improvement. this is going to depend on how much fouling builds up as well as how long the chillers run. The electrical power demand of the chiller to produce this is 460kw. the metric calculation would be: 2,500kw 460kw = 5.4 so the cop is 5.4. this means that for every 1kw of electricity you put into the machine, you will produce 5.4kw of cooling. the imperial calculation would be: first convert btu’s to kw’s. 8,533,364btu s 3412.142 = 2. Air and moisture are two non condensables that can leak into low pressure chillers. non condensables can reduce chiller efficiency by as much as 4% at 60% load and 7% at 100% loads. air insulates tubes, preventing exchange and elevating condensing temperatures, which also makes the compressor work harder. Here are three things to consider when making operational changes to guarantee the efficiency of chillers all year long. 1. consider variable speed retrofits. most components within a chilled water system will benefit from variable speed drives. in fact, most current energy codes require vfds for these components in new systems and major retrofits.
