4. Single Phase Motor Speed Control
Most AC compressors need to run at full speed only 25% of the time.
There are a billion single phase, single speed motors that are used in air conditioners, heat pumps and refrigeration compressors in the USA; these could run at half speed 75%+ of the time.
Annual electricity savings would be huge.
Peak demand would cease to be a problem.

5. What Nikola Tesla Never Knew…
Existing single phase electric motors can run at half speed ( RPM) at about half torque at about half the electricity (KWH) consumed and NOT overheat.
There are no useful speed controllers for single phase electric motors on the market.

6. The Fix
A black box can be added to any single phase electric motor to make it run at any number of speeds down to 25% with proportional torque and electricity consumption reduction and not overheat.
$Payback will be under a year (depending on climate and internal heat load) .

7. Caveat
Some AC / heat pump / refrigeration equipment might need to be fitted with a different thermal control expansion valve TXV if the existing valve will not provide proper expansion at lower RPM (“out of range”).
A wider range off-the-shelf high-efficiency valve can be installed.
The Cirrus “black box” can contain a circuit for an electric thermal control expansion valve.

8. The Good News *Working test units and patents needed.
The Cirrus “black box” can contain a circuit to operate an off-the-shelf electronic thermal control expansion valve.
Cirrus has a break-through design for an electric thermal control expansion valve WITH NO MOVING PARTS.*
This will provide the highest possible efficiency under all operating conditions.
The Cirrus valve is very low cost (a “disruptive technology”).
*Working test units and patents needed.

9. Extras All with hundreds of hours of testing in our heat chamber.
Cirrus has a design for a very high efficiency condenser fan blade.*
Working blade on hand was tested 500 hours.
An on-hand proportional speed condenser fan controller can be added to any system to save an average of ½ horsepower / 1,600 Watts / 1.6 KWH per hour of operation!
All with hundreds of hours of
testing in our
heat chamber.
*With special design fan shroud.

10. The Cirrus Technologies motor speed controller:
Environmental
The Cirrus Technologies
motor speed controller:
Due to significantly less electricity used:
= up to and over 50%+
Reduction of carbon and CO2
Reduction of greenhouse gasses
Reduction of pollutants
Significant reduction on
reliance on foreign oil

11. Next Steps:
Accelerated Life Testing (A.L.T.) on running systems at all speeds.
SEER rating.
UL certification.
Endorsement of the design and the equipment.
Technology credibility for wide spread rapid deployment.
