Air Conditioning and Refrigeration Systems Oil Fouling
The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) have addressed the results of the interaction between the oil and the refrigerant. Oil fouling of the heat transfer surfaces of air conditioning and refrigeration systems, will cause a loss of about 7% efficiency the first year, 5% the second year, and 2% per year the following years. According to ASHRAE, performance is degraded by as much as 30% due to the build-up of lubricants on internal surfaces. Higher percentages up to 40% have been observed in systems 20 years old or older.
1998 ASHRAE Handbook, Refrigeration, Chap. 6.7
There is no one product line that can have such an impact on the environmental movement,
sustainability and your bottom line.- Oil is needed to lubricate the compressor’s cylinder, rings and piston to prevent burnout
How Oil Fouling Occurs
- - This oil leaks around seals and into the refrigerant loop
- The refrigerant then carries the oil particles into the coil system
There is no one product line that can have such an impact on the environmental movement,
sustainability and your bottom line.- Unwanted oil contaminates the coils making them dirty
Visual Effects of Oil Fouling
- This Oil Fouling happens continuously until the coils are completely covered with oil
- After just a few years in operation, your HVAC unit is operating at only 60-70% of original design efficiency
PermaFrost fills in the Space Lattice
PermaFrost ® is a 3-Part Chemical Solution to the Mechanical Problem of “Oil Fouling”
PermaFrost® then imbeds itself into the space lattice of the metal at the molecular level, forming a microscopic filler and coating that increases the thermo conductive properties of the metal itself
PermaFrost® first dislodges the oil adhering to the inner walls of the coils, putting it back into circulation where it is picked up by the dryer filters or returned to the sump
By reducing the laminar friction associated with “oil fouling”, PermaFrost® increases the flow rate of the refrigerant, improving the heat transfer of the system
Basic Refrigeration Measurement
What is Delta T?1.
Why is it used?2.
What can change it?3.
Difference between Supply Side and Return Side Temperatures
Like a fever, it is an indicator if something is wrong with HVAC system
A whole number of things such as…
Delta-T issues that your Service Technician can have an impact on:
• Pressure Levels (refrigerant)• Flow (air or refrigerant)• Filters• Dirty coils• Several other issues
There is one important thing affecting Delta-T that your service technician cannot do anything about without taking your system out of service…
Clean the oil off the inside of the coils.
How much does Delta-T affect cost?
•16-19º is optimal target of efficient HVAC systems
• Every 1º in lost efficiency = 4% more power used
• Every 1º in improvement = 4% total power saved
Lower Delta-T = Shorter Equipment Life
When the Delta-T is out of optimal range, your HVAC systems…
Runs longer
Wears out faster
Breaks down more often
Wastes energy
Costs your company $$$$
What PermaFrost® will do…
Installed into the lowside port while the unit is running, PermaFrost® will clean the coil system from the inside and prevent the oil from reattaching to the surface ever again
PermaFrost® will return the “fouled” oil back to the dryer filter or oil sump where it belongs
PermaFrost® will aid in lubricating the compressor by treating the metal, making it smoother and slicker, reducing amp draw
PermaFrost® will protect your overall HVAC system from common degradation problems
What PermaFrost® will not do…
PermaFrost® is not an oil additive. It will not change or negatively affect the chemical properties of the oil in an HVAC system in any way.
PermaFrost® uses refrigerant as a transport mechanism to deliver the product throughout the coils, but it will not stay suspended. It takes itself out of circulation by completely imbedding into the metal lattice within 30-60 days
PermaFrost® will not harm your system; it’s chemically impossible when right product is correctly matched to the system’s refrigerant.
Value Proposition of PermaFrost®
• A one-time eco-friendly sustainable treatment that delivers lifetime system efficiency by permanently improving cooling performance
• Improved thermodynamic characteristics of the heat exchange process means less run time, lower energy costs, and longer equipment life
• Sold by the ton of cooling capacity of a system, the ROI for PermaFrost ® is measured in months instead of years
• Treated units reach set temperatures quicker, allowing them to shut off or throttle back and there are no better KWh savings than OFF!
Now that’s GREEN!
How you know PermaFrost® is working?We measure Delta-T (difference between supply side and return side temps) directly at the unit to minimize the effects of building variables on the test results.
Powertron Global guarantees a 2° improvement in Delta-T and/or 5% more in Energy savings or we’ll refund the cost of the product.
We measure COP (coefficient of performance) which equates to cooling efficiency by determining the Kilowatts needed to produce one ton of cooling capacity.
Powertron Global guarantees 4% COP improvement in a chiller or we’ll refund cost of the product.
Reduce Energy ConsumptionCitibank installed PermaFrost™ in 51 of their retail branches in southern Florida. The results showed a decreased kWh consumption of 8% from July to December of 2008 and 9.9% reduction from January to June of 2009.
The following year showed approximately 9% reduction of kWh off the power bill which was due to 18-20% less energy used by the HVAC units treated with PermaFrost™
This data compelled Citibank to begin a worldwide rollout of PermaFrost™.
Citibank already has over 1,000 installations.
Reduce Carbon Emissions
According to the US Department of Energy, for every 1,000 kWh saved by the “off-time” there is a reduction of 1,341 pounds of CO2 released into the atmosphere.
In just one year, Citibank reduced their kWh consumption by 1,292,724 kWh in the 51 locations in South Florida.
That means Citibank reduced their green house gas emissions by 1,712,575 lbs for the 12 month period.
