Ray Mckenzie and Mac Chaney designed the RayMac Compressor and obtained US and International patents on an Advanced Concept Linear Compressor.

Realizing the huge stress placed upon sustainable energy from heating and cooling demands in residential and small to medium-sized business locations, we began work on a sizable energy reduction plan. Our objectives began to focus upon developing a sustainable HVAC compressor with as many advanced features as possible to improve the environment in the most efficient way. However, we realized that with our advanced concept, we could offer many more features that would allow us to serve energy reduction in other markets as well. In the process, we began to focus upon common HVAC problems in other compressors as well.

We began with a "design by objective" approach to focus upon efficiency and improving compressor reliability. We soon realized that this approach was obviously missing and deficient in previous designs. Except for the scroll compressor, which reduced part of the rotating mass, compressor technology has changed little in a century. Thus, industry demanded a disruptive solution to the overall industry problem.

By building a Pareto distribution of almost every failure in half a million field units, we sorted them into a descending list as shown below and began to work on eliminating the highest cost factors. It became obvious that the current technology made it virtually impossible to eliminate many of the HVAC failures we tracked.

By designing an advanced concept linear compressor, we ;
1. Eliminated the possibility of Hydraulic Lock
2. Eliminated the need for both start and run capacitors.
3. Eliminated the compressor cycling, the resulting power surges and the associated noise.
4. Eliminated approximately 98% of the friction inherent in the conventional rotating mass compressor.
5. Eliminated much of the moving mass that produced excessive friction and wear during operation.
6. Eliminated more than 90% of the expensive and weighty copper inside conventional compressors.
7. By varying the stroke, we managed the compressor output to meet the demands upon the system
gaining an additional 20% efficiency and with an overall efficiency of up to 50%.
8. By utilizing advanced non conductive materials, we minimize heat transfer from the hot zone.
9. To match the improved efficiency and reliability of the linear motor, we designed a floating valve in the
end of the piston.
11. No oil in the refrigerant gives a 3% gain in efficiency.

In addition, we reduced the compressor weight, manufacturing costs, electric power requirements, noise, machining cost, and the costly power surges. The compressor would be a good candidate for robotic assembly.

By using one major moving part, we doubled the reliability and the life of the system compared to conventional compressors. The cost of manufacturing would be comparable to conventional compressors.

Over 1 Billion compressors in the 2-4 ton range are manufactured worldwide each year. If we supplied 1% of the market and saved only $10 in energy cost per unit per year, that is $100,000,000 in energy savings!
