Comparative Analysis 2011 Sanyo 10 Ton HVAC And Sanyo 10 Ton HVAC Equipped with Mysticool® Max from XDX®

Summary Overview • A validation was conducted under laboratory conditions of a Ten (10) Ton Sanyo HVAC and Heat Pump System • Heat Pump operation demonstrated a hotter supply air temperature making the unit more suitable for operation in colder climates. Energy consumption was reduced by ~ Twenty (20)% • HVAC improved capacity 19. 8% while reducing k. Wh. EER was improved. • Baseline: » » 101, 512. 80 BTU/Hr 8. 45 Tons of Net Cooling Effect » 8. 968 EER • Mysticool® Max from XDX®: » 128, 837. 46 BTU/Hr » 10. 74 Tons of Net Cooling Effect » 13. 81 EER – Energy was reduced by 17. 6% (In line with Global Results) – Reduction in k. Wh of 1. 99 per hour (16 hours 31. 84 k. Wh per day per system) – 31. 84 k. Wh would amount to ~ ¥ 19. 19 daily

Validation Protocol • • • Test was conducted upon Sanyo Heat Pump and HVAC in sequential baseline tests. Generator was operated to run at 50 Hz Voltage, k. Wh, Amperage, k. W, PF were monitored Temperatures, Pressures, RH% were recorded at Ten (10) second intervals. Test was repeated upon addition of Mysticool® Max and Heat Pump Optimizer™ from XDX® to the Sanyo Heat Pump and HVAC in sequential tests.

Heat Pump Comparison Test was conducted upon Sanyo Heat Pump in sequential baseline tests and was repeated upon addition of Mysticool® Max and Heat Pump Optimizer™ from XDX® to the Sanyo Heat Pump in sequential tests. The Piping Diagram of the Heat Pump Optimizer™ from XDX® is shown. On the following slides, graphs of performance data and power are shown. Work has not been calculated as the supply outlet air relative humidity sensor became erratic during the baseline test for the heat pump and with only the return air relative humidity sensor operational, delta h could not be determined. Warmer discharge temperatures and a larger delta T is clearly demonstrated.

HVAC Comparison Test was conducted upon Sanyo HVAC in sequential baseline tests and was repeated upon addition of Mysticool® Max to the Sanyo HVAC in sequential tests. The Piping Diagram of the Mysticool® Max from XDX® addition to the Sanyo HVAC is shown. On the following slides, charts of airside performance data and power are shown. Work has been calculated as the supply outlet air relative humidity sensor operation was restored and calibrated; delta h therefore has been determined. Colder supply air temperatures, a larger delta T and Delta RH% are clearly demonstrated, and EER is calculated.
