Energy Efficiency of Air Conditioning Units

Energy Efficiency

HVAC typically accounts for 40-50 percent of the total energy bill for businesses and commercial buildings. Any inefficiency in your air conditioning system will be shown by higher than expected electricity bills and continuous breakdowns.

Over time the surfaces of air conditioning coils become dirty as the air moving over the coils contain dust, dirt, pollen, moisture and other contaminants. A build of of these contaminants decreases the available surfaces area for heat transfer, reducing the efficiency of the heat transfer process, leading to excessive energy consumption and poor system performance. It is important that air conditioning coils are regularily inspected and maintained to ensure optimum performance.

Heating, ventilation and air conditioning (HVAC) is essential in most settings to ensure a pleasant, comfortable and safe work environment. In commercial buildings in Australia, 70 percent of energy usage and 63 % of greenhouse gas emissions are estimated to be contributable to heating, cooling and ventilation. HVAC typically accounts for 40-50 percent of the total energy bill for businesses and commercial buildings. Any inefficiency in your air conditioning system will be shown by higher than expected electricity bills and continuous breakdowns.

Simply cleaning your air conditioning system and protecting it from corrosion and slim can save you electricity. Corroded dirty systems are very inefficient and don’t cool as they were designed. The systems have to work hard and ultimately use more power.

In the Office

Regular cleaning and maintenance of your air conditioning system will save electricity and maintain the systems efficiency. Keeping your system working efficiently will also greatly improve the indoor air quality of your occupied space. Not only will your system cost less to run but also the occupants of the building will feel better with better indoor air quality.

The COIL DEFENDER range of cleaners and coatings enhances your systems ability to maintain a constant temperature and humidity while working efficiently. The coatings will extend the life of the unit and allow it to operate as it was designed.

Graph of Energy Efficiency Coated vs Uncoated HVAC Coils

The data above shows a comparison between a coated HVAC coil and an uncoated HVAC coil. In just 12 months the uncoated HVAC coil lost 7 % efficiency. This would equate to a higher electricity bill for the uncoated air-conditioning unit.
