"If you want to find the secrets of the
universe, think in terms of energy, frequency
and vibration" - Nikola Tesla

In my many decades of Energy Research, I have determined that
one of the most energy efficient pieces of equipment on the planet is
the freon heat pump.

Today's state of the art compressors can operate at a Coefficient Of
Performance, i.e.. Output divided by Input of 3-5 (300-500%
efficiency) which is very good. But I believe the COP can be
increased to >10+.

A freon compressor produces a high pressure gas inside the pipes
and heat-exchangers of an HVAC unit, in order to produce the
cooling/heating effect in air conditioners and refrigerators. A lot of
energy is required to produce that pressure. But, that pressure is
wasted in today’s modern freon compressors, because the pressure
is dissipated in the expansion valve and/or the orifice tube, and
called Adiabatic expansion. (*See below)

That pressure drop could be turned into work in an expansion
turbine, if attached to the same shaft as the freon compressor motor.
The compressor discharge could  help turn the motor shaft that runs
the compressor. So, instead of using 3,700 watts to run my
geothermal heat-pump compressor, to supply 3 tons of
cooling/heating to my home, it may be possible to put 85% of that
input power directly to an expansion turbine, that puts torque to the
shaft, thereby increasing the COP, to >10+.  Therefore I could heat
and cool my home with 370 watts. Now that is a machine that should
sell very well to OEMs as well as the retrofit market.

This proposal is based on an idea put forth by Peter Lindemann.

video for more information.

The one thing I’m still trying to work out is how to route the high
pressure liquid/gas to the expander. It may require a second 4 way
reversing valve in parallel with the existing 4 way reversing valve. I
am looking for collaborators to work on this proposal as an open
source project. There is plenty of room in the HVAC market for all
comers, in my opinion. Please use the "Contact us" app for feedback

*Adiabatic process Description:
An adiabatic process occurs without transferring heat or mass
between a thermodynamic system and its surroundings. Unlike an
isothermal process, an adiabatic process transfers energy to the
surroundings only as work. Wikipedia
