Is your AC not cooling as well as it used to?
Three signs that your A/C system is no longer working efficiently:
- the temperature of the air dispensed is not as low as it was initially;
- the system is noisier than usual;
- the energy consumption is higher and, therefore, the bill as well.
Why does the efficiency of an AC/R system decrease?
The reduction of an AC/R system efficiency could be due to:
- the presence of leaks or micro leaks in the rubber and metal components of AC/R systems (a specific case explained by our R&D Manager in an interview that you can read here)
- a reduction of the heat exchange between the refrigerant and the system’s heat exchangers.
Let’s see the reasons linked to the second point and, above all, how to solve the problem with an easy, safe, and fast method.
Studies estimate that, on average, between 1% and 8% of the volume of compressor oil is carried by the refrigerant throughout the system, generating what is known to experts as oil fouling.
As time passes, some of this oil becomes less soluble and heavier, ending up settling inside the condenser and evaporator pipes.
These residues reduce:
– the diameter of the pipes
– the heat exchange
– the volume of lubricant in the compressor and, therefore, its lubricity
A further problem caused by oil fouling is that these residues collect moisture in the system, triggering acidification and oxidation processes, conditions that inevitably decrease its efficiency. Research carried out by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) has shown that oil fouling generates a 30% reduction in system efficiency.
Easy, fast, safe: the method that restores the original efficiency of an A/C system reducing electricity consumption by 20%.
Understanding and preventing oil fouling is essential to guarantee a long life for your air conditioner! That’s why experts suggest using specific additives to remove oil residues and prevent the formation of new ones.
Cool-Shot Ultra is the additive developed by Errecom to quickly and easily solve the oil fouling problem in air conditioning and refrigeration systems and restore their original efficiency. Consisting of two synthetic catalysts and a lubricating agent, Cool-Shot Ultra removes all the lubricant sediments settled on the walls of the system, solubilizes them, and conveys them back into the compressor.
Compatible with all refrigerants (CFC, HFC, HCFC, R32, HFO), except R717, its efficacy is immediately visible in older systems, while when used in new systems, it performs a preventive action, avoiding the natural efficiency reduction over time.
Research carried out by Errecom’s laboratory has estimated that the use of Cool-Shot Ultra leads to the following benefits:
-5°C in an extremely short time
+76% heat exchange
-20% system energy consumption
+62% compressor lubricant efficiency
+80% AC/R system lifetime.
NOTE: The data shown come from an average of the results recorded by Errecom after having placed Cool-Shot Ultra into different types of AC/R systems (old, new, containing different lubricants and refrigerants).
With Cool-Shot Ultra, additionally, you also contribute to sustainability and the future of the planet.
On the one hand, Errecom’s innovative patented injection method ensures that the problem is solved with a tiny amount of product and zero waste: because “less is more”. On the other hand, by restoring system efficiency, Cool-Shot Ultra reduces energy consumption and CO2 emissions.
Filling Cool-Shot Ultra into the system is extremely easy.
