EER

• Energy Efficiency Ratio =

Cooling Capacity in Btu / Hr

Power Consumption in Watts

Mechanical Subcooling• Moving cooling

load from the main compressor to the subcooling compressor increases efficiency.

R410A - A New Opportunity

• R410A = compressor EERs of 14 to16

• Not a refrigerant for medium or low temperature refrigeration.

• Line sizes must stay small due to high pressures, which points toward a one on one design.

R410A Subcooling Medium Temp

• R410A EER = 16.0

Frio Verde and R22 to R404A conversions.

    1.  Some stores are converting R22 to R404A.

    2.  Standard R404A has 66% more mass flow than R22 for the same heat transfer.

    3.  The mass flow increase calls for suction line re-piping with standard R404A systems.

    4.  Frio Verde R404A has the same mass flow as R22 due to subcooling at 50 ºF to 60 Deg ºF.

    5.  Frio Verde saves $30k to $40k of re-piping cost on a 50,000 sq ft. supermarket conversion.
