CO2 Cascade Rack System
DETALLES DEL PRODUCTO
A Natural Refrigerant Solution
Hussmann’s cascade rack is a low temperature subcritical direct expansion refrigeration solution using CO2, a naturally occurring refrigerant. The use of CO2 as a refrigerant reduces the HFC charge with a minimal impact on energy efficiency to reduce the carbon footprint of the system.
Unlike CO2 secondary or liquid recirculation systems, cascade CO2 systems use a vapor compression cycle similar to traditional direct expansion systems. Instead of condensing against ambient air or water, the CO2 condenses against a primary refrigerant.
CO2 Cascade Environmental Advantages vs. Traditional Rack Systems:
- Rejecting heat to another refrigerant
- Provides flexibility with regulatory changes
- Designs include R-449A and R-513A to further reduce GWP
- Reduces the efficiency impact of high ambient temperatures
- Use of a lower cost natural refrigerant
- GWP of 1 vs. R404A with 3920
- Approximately an 80% reduction in total refrigerant cost
- 60-70% Reduction HFC charge
- All HFCs are removed from the sales area for low temperature loads
- Primary HFC receivers sized for winter flooding charge
- 30-50% Reduction in carbon footprint
- Reduction in the HFC charge
- All low temperature circuits are CO2
- Less HFC piping equals fewer HFC leaks
- Use of CO2 as refrigerant
- Smaller diameter piping required
- CO2 has 7x the volumetric efficiency of R404A which reduces line sizing tremendously
