What are the major differences between an R-22 and R-410A compressor?

There are three distinct design differences between and R-22 and R-410A compressor:

* Different Oil: Because mineral oil, normally used in R-22 compressors, is not miscible with HFC refrigerants such as R-410A, Copeland uses a synthetic Polyol Ester Oil (POE) in R-410A approved compressors.

* Reduced Compressor Displacement: A pound of R-410A has approximately the same heat carrying capacity relationship to R-22 as R-22 has to R-12, therefore, the compressor displacement has to be reduced approximately 40% for a given motor horsepower. Using a compressor designed for R-22 to pump R-410A would overload the motor and cause protector trips.

* Higher Shell Burst Pressure Requirement: At any given saturated temperature, R-410A has approximately 60% higher pressure than R-22, which require compressor shells to meet this higher pressure requirement.

Benefits of Going Green: Return on Investment (ROI)

As development continues to take its toll on the environment, there is a growing impetus to further the importance of green building and sustainability. While governments are implementing regulations and incentives to drive building owners to consider sustainability strategies, it is equally important to understand its financial benefits before investing in these methods.
