SUMMARY:
The goal was to demonstrate operation under all conditions to instill confidence in XDX® technologies used with XSTREAM technology, with regard to improved performance and reliability. The patented XSTREAM® technology from XDX® performed to expectation and is a desirable solution for the Commercial Refrigeration Equipment.
The complete installation time for the retrofitted technology, including pump-down, piping, evacuation, and adjustment was three and one half hours, or 1.75 hours per evaporator.
Substantial energy and performance benefits are experienced.
In the segment of totalized data collection, in summary†:
• Baseline average daily electricity usage of 94.19 kWh is 18.39 % higher than with operation with XDX® which had a daily average of 79.56 kWh.
• Baseline average demand of 4.87 kW is 50.77 % higher than operation with XDX® which had a kW average of 3.23 kW.
• Baseline average Maximum kW of 8.49 is 35.84 % higher than with XDX® which had an average Maximum kW of 6.25.
• Power factor, kVA and amperage were also consistently lower with the XDX® operation.
• Compressor protection has improved through more stable superheat.
• Defrost was reduced from three (3) defrosts daily to one (1) defrost daily.
Annualized savings of average maximum kW at 0.49 to 2.82 kW reduction
($10 per kW per month at twelve months) $58.80 to $338.40
Annualized savings of average kWh at 9.57 to 19.98 kWh reduction per day
(8 cents per kWh and 12 cents per kWh) $279.44 to $583.42
