Background

  • Peak Demand on cooling meets solar Peak
  • Cooling creates expensive peak demand
  • Cooling is the biggest single user of

electricity in buildings

  • Electric Energy Savings

– Electric COP Solar Cooling System incl. recooling ~10-40 – Electric COP Compression Chiller Syst. incl. recooling ~2-6  reduced electric consumption by 70-80%

  • More stable energy expenses
  • CFC Free Chillers – No Ozone Depleting Potential
  • LEED certification - up to 10 additional points possible
  • Quiet operation – no vibrations
  • Reliable operations – no wear and tear on pistons or screws

as there are no such stressed parts
