Join me in an interview with Don Yeganeh...
Don is a licensed Professional Engineer in New York State and also a Certified Measurement and Verification Professional who graduated from Columbia University as a Mechanical Engineer in 2009. Since then he has spent 6 years as a commissioning engineer and the last 2 years of his professional experience has been with a start-up company Ener.co
In our interview we talk about the existing problems with Air Cooled Condensers and, their special coating solution, that has a payback in less than a year in some cases. Enercoat® is a performance coating designed to prevent corrosion and increase thermal conductivity, resulting in the most energy efficient condenser coils on the market. Their coating does the following:
Reduction of energy cost by 14%
Increase in energy efficiency by 50%
Reduction peak kW consumption by 8%
Increase in cooling capacity by 55%
Improvement of indoor air quality with an increase in moisture removal
and YES they have the field monitoring devices that prove these results.
Air-cooled heat exchangers lie at the heart of the energy efficiency of air conditioning systems. Weather, environmental conditions, dirt and debris are constantly damaging outdoor cooling equipment. Untreated coils begin to corrode from the first day they are exposed to the elements. There is an estimated 3 – 5% loss in efficiency per year due to corrosion.
Traditional coatings aim to create a smooth fin surface that accumulates less debris over time and protect against fin corrosion. However, traditional fin coatings noticeably impair thermal conductivity – how well heat is transmitted. These coatings possess low levels of conductivity, transfer less heat, and negatively impact energy efficiency. They are also susceptible to tears and cracking, which leaves gaps at the point of the fin-to-tube bond or unfinished edges where fins are cut during the manufacturing process.
Their product Enercoat® addresses all of these issues by:
Inhibiting causes of fouling and the adhesion of dust and grime to coils
Decreasing power consumptionIncreasing cooling capacity
Optimizing compressor operation; reduces stop/start cycles; extends compressor life.
Extending overall equipment life, deferring capital investment in new a/c units
Why is their coating so special?
They have leveraged graphene nanomaterial technology to create a one-of-a-kind coating that delivers real performance change. Multiwall nanotubes of carbon (CNT) and graphene have a very high thermal conductance. The products twin properties of high thermal conductivity along the axial direction and poor thermal conductivity in the radial direction provide an excellent heat conduction channel that can confine heat currents on the nano scale. Incorporating these at high doses into a polymer produces a stable corrosion protective conductive layer. Application to the metal surfaces of tubes and fins in a heat exchanger ensures the retention of a condenser’s heat exchange capacity. Nano layers of conductive graphene platelets enhance the coating and makes it extremely conductive both electrically and thermally.
