THE BIG PROBLEM
“The IEA says cooling accounts for 70% of building energy consumption worldwide. New demand will require new electricity production the equivalent to the combined electricity capacity of the United States, the EU, and Japan today.“
“Growing demand for air conditioners is one of the most critical blind spots in today’s energy debate. Setting higher efficiency standards for cooling is one of the easiest steps governments can take to reduce the need for newer power plants, cut emissions and reduce costs at the same time.”

APPOLLO’S TECHNICAL ADVANTAGE
All HVAC systems require “phase change” to operate. Phase change happens at predetermined temperature and pressure for a giving working fluid illustrated by the graphic at right.
Incumbent technology compresses refrigerant which heats the gas requiring even higher pressures in order to change phase from gas to liquid. This is a near runaway scenario exemplified by the red line.
SOLUTION: Appollo’s patented technology expels heat during the unique centrifugal compression process. The result is that the refrigerant condenses into a liquid lower on the phase change curve saving in excess of
30% of energy.
410A holds 1000X more heat compared to CO2 when released into the atmosphere
CO2 systems are inherently more energy intensive because co2 is a heavier gas
Appollo’s efficiency is due to its isothermal turbo compression which makes CO2 a viable alternative to “green” 410a
Solar powered air conditioners are battery powered. Incumbent technologies have a large start up surge which creates an expensive engineering hurdle. Appollo’s rotating turbo compressor can be ramped up slowly eliminating this “surge hurdle” making it ideal for off-grid and military applications.
