Conversion of existing HVAC equipment, typically centrifugal chillers, to operate on the alternative refrigerants should by undertaken only when economically or operationally appropriate. An engineered conversion should be made in consultation with the original equipment manufacturer to ascertain the effect on capacity and energy usage, and to determine the proper conversion program to minimize degradation in capacity and increase in energy consumption. Consideration should be given to supplementing lost capacity with an additional chiller by comparing the cost of this approach to the cost of the various conversion options.
