HOW IT WORKS



A/C Re-New improves the lubrication in the compressor of you air conditioner and system's heat transfer capability so that it will blow colder air. As a result, air conditioners with A/C Re-New will run less, use less electricity, last longer, and run quieter. See the Efficiency Loss Due to Oil Build Up graph below. With the cost of energy rising every year on average of 3% per year, doesn't it make sense to reduce long-term consumption without sacrificing your lifestyle?

The video below demonstrates how A/C Re-New improves the efficiency of air conditioning systems.

Excerpt from ACHR News article by Jack Sine

"Everyone knows that excess oil in a chiller’s refrigerant can create serious performance problems. But what many don’t know is the frequency with which oil migrates to the refrigerant side and what percentage of chillers and refrigeration systems suffer from oil logging."

"In recent years, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has been emphasizing that not only does oil entrained in the refrigerant of a chiller significantly degrade performance, but it is also a far more common problem than previously thought."

WHAT IS IT?



A/C Re-New is a remarkable breakthrough in lubrication technology for residential and commercial air conditioning systems that dramatically improves the performance and efficiency of your unit. It is a synthetic oil that is injected into your air conditioner and mixes with the system's existing oil and refrigerant to reduce friction and wear in the compressor and to improve the heat transfer characteristics. To better understand how A/C Re-New improves your air conditioner, let's first quickly review how an air conditioner works.

How does an air conditioner work?

The goal of an air conditioner is to transfer heat from one place to another. In your home or business, quite simply, heat inside is transferred outside. This is accomplished through the heating and cooling of a liquid, commonly referred to as a refrigerant in air conditioning systems.

In your home, the air that needs to be cooled is blown across coils that contain the refrigerant. The refrigerant absorbs the heat from the air. The refrigerant then travels to the outdoor or condenser coil where the heat is released. Since the refrigerant absorbs the heat, the resulting air inside is cooler and less humid. This cooler air is then blown back through your house or building.

Ways to improve your air conditioner

One way to improve how well your air conditioner cools your home is to improve the refrigerant’s ability to absorb heat. The more heat it can absorb, the cooler the resulting air.

Another way to improve how well your air conditioner cools your home is to improve the equipment (the compressor) that pumps the refrigerant throughout the house and extracts the heat out of the refrigerant. The more efficient the equipment pumping the refrigerant and releasing the heat, the faster your house can cool, and less amount of energy it will take to do so.

Oil Compatibility

All air conditioner’s have oil to help lubricate the compressor. There are three different oil types and A/C Re-New is compatible with all standard air conditioning oils - mineral oil, alkylbenzene, polyol esters.

Refrigerant Compatibility

Depending on type of air conditioner and when it was made, your system can contain one of many different refrigerants. Fortunately, A/C Re-New is compatible with all standard air conditioning refrigerants and with standard system materials - metals, polymers and plastics. Refrigerant compatibility includes:

CFC – R11, R12

HCFC – R22

HFC – R134A, R410A

ASHRAE-97 TEST



Standard
ASHRAE 97 (American Society of Heating Refrigeration and Air Conditioning Engineers)
Title
14 Day Sealed Tube Method to Test the Chemical Stability of Materials for Use within Refrigerant Systems
Purpose
The primary industry test that establishes how the thermal and chemical properties of metals and refrigerant are impacted over time when exposed to the lubricant.
Description
The lubricant is sealed in a tube along with the refrigerant, various metal specimens, and elevated moisture levels. The tube is then taken to 347°F and a high pressure for 14 days. Stability is measured by the degree of refrigerant decomposition, metal deterioration, acid formation and visual appearance of the oil. The test and results are extensive. A/C Re-New was tested with R-22, the standard refrigerant in most home and business air conditioners, and against an industry standard oil - POE.
Results
The full results are too extensive to list, but A/C Re-New exceeded the standard in all scenarios. Results show significant improvement in chemical stability and metals protection. Some of the key test results with Zerol Ice are:

R-22 decomposition was reduced by 60%

Corrosion of copper was reduced from 384 ppm to 56 ppm (86%)

Corrosion of steel was reduced from 21 ppm to 0.05ppm (99%)

No increase in the total acid number (TAN)

Oil retained clarity and cleanliness in appearance

What does this mean to me?

A/C Re-New will not impact the refrigerant over time.

A/C Re-New will not impact the metal components of your air conditioner over time.

This is one of the reasons why one application lasts the lifetime of the air conditioner.

HEAT TRANSFER TEST



Standard
ASTM D2717
Title
Standard Test Method for Thermal Conductivity of Liquids
Purpose
This test evaluates how well the lubricant conducts or transfers heat.
Description
The tests results in a factor. This factor indicates how much heat is transferred. The higher the factor, the better the lubricant's ability to transfer heat. A/C Re-New was compared against mineral oil and POE.
Results

A/C Re-New is 5% better than mineral oil

A/C Re-New is 10% better than POE

What does this mean to me?

A good air conditioner is one that is able to more effectively transfer heat – move heat from inside to the outside.

Improved Heat Transfer => Cooler Air

Improved Heat Transfer => More Efficient System => Reduced Energy Consumption

FALEX PIN TEST

Standard
ASTM D2670 & D3233
Title
Standard Test Methods for Measurement of Extreme Pressure Properties of Fluid Lubricants (Falex Pin and Vee Block Methods)
Purpose
The test is used to evaluate wear and tear, friction and extreme pressure properties of materials and lubricants.
Description
A rotating pin, also referred to as a journal, is lubricated with the test oil and is compressed between two vee-shaped blocks. Pressure (depicted by the red arrows) is added at increasing levels until the pin fails. The goal is to determine how much load or force the lubricant can withstand before it fails. Therefore, the higher the load, the better the lubricant. Three typical industry oils (Mineral Oil, Alkylbenzene and POE) were tested, both alone and then mixed appropriately with A/C Re-New.
Results
A/C Re-New significantly improved the oil's load-to-failure points.
What does this mean to me?

Improved lubrication reduces the friction between the air conditioner compressor's moving or wear surface. Less friction results in lower energy (electricity) demand and reduced incidence of failure.

Higher Pressure Tolerance => Less System Failures => Lower Maintenance Costs

FOUR-BALL FRICTION TEST



Standard
ASTM D4172 & D5183
Title
Standard Test Method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method)
Purpose
This test evaluates how well the lubricant reduces wear when metal is rubbed together.
Description
Three steel balls, which are immersed in the lubricant being tested, are locked into a test cup. A fourth steel ball is placed on top of the three steel balls and is rotated at a speed of 1,200 rpm under a 40 kgf (kilograms of force) load at 167ºF (75ºC) for one hour. After the one-hour test period, the three stationary balls are washed and the wear scars are measured to the nearest 0.1 mm. The smaller the scar, the less the wear, and the better the lubricant.
Results
A/C Re-New significantly reduced the scarring of the balls.
What does this mean to me?

Less Scarring => Less Wear and Tear => Longer Lasting Equipment

Less Scarring => Less Friction => Lower Energy Consumption

Less Scarring => Less Friction => Quieter System

COMPRESSOR WEAR TEST



Standard
Consulting Services International, Louisville, KY
Title
Compressor Wear Analysis
Purpose
This test evaluates how well the lubricant reduces wear when metal is rubbed together in various compressors.
Description
Six reciprocating compressors and six scroll compressors were tested with R-22 refrigerant at full load for a period of 500 hours. The reciprocating compressors used mineral oil while the scroll compressors used alkylbenzene. A/C Re-New was applied to three reciprocating and three scroll compressors.
Results
The full results are too extensive to list, but A/C Re-New performed well in all scenarios. Some of the key results are:

Reciprocating compressor – bearing wear was significantly reduced in those compressors containing A/C Re-New

Scroll compressor – bearing wear and copper plating was reduced in those compressors containing A/C Re-New

See below for some example results

What does this mean to me?

Equipment will last longer - less scarring means less wear and tear on the equipment.

Reduced scaring also reduces friction which results in lower energy consumption.
