History of Cold-Plus®

Early Days

About COLD-PLUS : Cold Plus is a THERMAL MANAGEMENT TECHNOLOGY chemical additive to improve the energy efficiency of all HVAC systems.

The compressor is the principal rotating shaft device in this system. The coolant (R22 in older units or R-410A or similar in newer units) is compressed into a nearly 100% liquid stream that moves across an evaporator heat exchanger and is partially vaporized as heat is removed from the room or building. The two-phase vapor-liquid stream then travels to the compressor inlet and is re-compressed and condensed. Compressors are predominantly lubricated with oil, categorized broadly as mineral oil or synthetic oil. The rotating seals of the compressor allow a small leakage of oil into the coolant. The oil slowly forms a boundary layer coating on the heat exchanger and other metal surfaces. This predominantly oil boundary layer lowers the heat transfer, requiring longer compressor run times to remove the building heat load and maintain the set temperature.

The Cold Plus, a multi-component suspension, is a once-per-HVAC mechanical system-life additive that displaces much of the oil from the inside boundary layer of metal surfaces and reestablishes a low friction (slippery) polymer (PTFE) to stabilize the metal surfaces. PTFE has a higher thermal conductivity of about 2.7 W/m K while oil is in the range of 0.15-0.25 W/m K. Cold Plus conceptually also reduces fluid drag for coolant flow and improves the heat transfer thus reducing the compressor run time, which at the power (kW) usage reduces energy (kWh) consumed.Cold-Plus™ is a proprietary inert nanoparticle-lubricant for use in the compressors in all HVAC and refrigeration systems.

This PTFE nanotechnology was originally developed by DuPont to increase laminar flow and reduce blood clotting in veins and arteries during invasive surgical procedures. Due to the similarities between a biological heart and a mechanical compressor, the proprietary component, PTFE (Polytetrafluoroethylene) , was then added to an industrial lubricant so that it could create similar results in mechanical systems.

The resulting compound is Cold-Plus™. It has been scientifically proven to reduce the energy consumption of HVAC/refrigeration systems and extend the lifespan of the unit. Cold-Plus™ is the only SRA (Synthetic Refrigerant Additive) with PTFE and is chemically inert and meets OSHA standards for handling safety. Its effect on increasing laminar flow, has been successfully tested at the National Renewable Energy Laboratory (NREL) in Golden Colorado, where it was verified that a 14% increase in laminar flow was achieved when using Cold-Plus™. These tests were conducted using a 20-ton Carrier cooling unit from Walmart.

The effectiveness of Cold-Plus™ in increasing HVAC performance and increasing the system’s lifespan have also been statistically verified by Dr. Elizabeth Clarkson, the Chief Statistician and Senior Research Engineer of the National Center for Advanced Materials Performance (NCAMP) in Wichita, Kansas. Cold-Plus™ has been proven to reduce the electrical consumption of compressors by up to 30% in some older units. Cold-Plus™ has also been successfully implemented and proven in over 20,000 homes, businesses and industrial refrigeration equipment over the last 10 years.

Technology : The basic premise is the primary determinant of efficient heat transfer is the laminar flow of the refrigerant. Oil-fouling in all cooling equipment deteriorates the heat transfer coefficients. Peer reviewed and published papers by Dr. Pete Jenkins, PhD. M.S. B.S. I.E.M and M.B.A confirm claims for patents and along with both Laboratory and Field tests at the University of Colorado have proven this to be a unique solution to the Oil-Fouling dilema with all manufactured HVAC compressors.

Increasing the heat transfer coefficient leads to higher heat flux as more heat is transferred from the surface to the boiling fluid. A one-time Cold-Plus treatment enhances and prolongs this phenomenon without any degradation. The original concept focused on reduced friction in the compressor, and thus reduced energy use, and the removal of oil fouling plus slippery PTFE treatment to prevent the return of oil fouling. The infusion of a micro/nanopolymer particle technonology that remain suspended in the system, has proven to greatly enhance thermodynamics – both heat and cold transfer. It became evident that there was much more involved than just decreasing friction.

Early testing gave results on older equipment much greater than anticipated. Further investigation pointed the way toward heat transfer increases and thus significantly increased efficiency and reduced energy usage.

One of the most important of these became the understanding of “oil-fouling” that occurs when lubricating oil begins to break down and deposit oil particles on metal surfaces within the system. This accumulation reduces the heat transfer ability of the system, and efficiency becomes more detrimental as the unit ages.

Many years of testing revealed a series of improvements that, when combined, today allows a significant increase in the efficiency and a reduction of required energy of the unit.
