WebVarious refrigerant-type air chilling systems have been successfully employed for combustion turbine inlet air cooling. These range from compressor-type chillers to absorption chillers, which utilize “waste” heat as an energy source for the chilling process. Thermal storage systems have also been successfully applied to CTs. http://www.accessen.com/support-and-service/fouling-factor.html
Webcan be caused by many factors, including the following: 1) uneven air flow distribution due to air-side fouling, and/or improper design and installation of evaporators; 2) uneven refrigerant flow distribution due to refrigerant-side fouling, and/or manufacturing and design defects of refrigerant distributors; and 3) uneven air-inlet temperature WebJan 23, 2024 · The fouling factor of the chiller is F.F: 0.0001, which is often said to be one ten-thousandth of the fouling factor.
