A.S.H.R.A.E. (American Society of Heating, Refrigeration, and Air-conditioning Engineers) has studied this problem. A.S.H.R.A.E. estimates that this thermal barrier accounts for up to a 30% reduction in efficiency within the first 5 years of the equipments life. 

As studied by A.S.H.R.A.E., during the refrigerant compression process, oil migrates from the compressor to the coil system contaminating the metals that transfer heat. Compressors that use oil for lubrication do not prevent oil from fouling the coil system. Even the smallest amount of oil in the coil system creates a film or coating that will hinder heat transfer reducing the efficiency of the unit.

All HVAC manufacturers know their equipment performance degrades once in service because of oil contamination in the heat exchangers. Most often they will not admit it and adamantly deny the issue. If you ask OEM employees and service partners they will usually deny the problem exists.

The industry does not want you the consumer to know that their equipment degrades in performance causing up to 30% more kWh usage in just a few years.

That little efficiency sticker and EER rating on your equipment is only true when it is new, not after it is installed and in service.

OEM’s do have a solution for the degradation…. BUY NEW EQUIPMENT!

PermaFrost NMR® is a High Value Energy Conservation Measure

 

  • Unmatched in terms of total financial return.
  • For most of our customers the decrease in kWh consumption across their portfolio equates to about a 10% savings on their total power bill.
  • Installation is simple and will not interrupt your business during roll-out.
  • Equipment runs less and lasts longer. Extend the HVAC’s equipment life.
