2. EER Energy Efficiency Ratio = Cooling Capacity in Btu / Hr Power Consumption in Watts

3. Mechanical Subcooling Moving cooling load from the main compressor to the subcooling compressor increases efficiency.

4. 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.

5. R410A Subcooling Medium Temp R410A EER = 16.0 R404A EER = 7.1 Transferred BTUs 200% Efficiency Gain Big Compressor Small Comp

6. R410A Subcooling Low Temp R410A EER = 16.0 R404A EER = 3.7 Transferred BTUs 400% Efficiency Gain Big Compressor Small Comp

13. 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.
