ENErgy SAviNgS/hvAC Air FiLTEr ByPASS AUTHOR carl nottberg, chief Marketing officer COMPANY bonded Filter company chAllenge: When reviewing the elements involved for a HVAC preventative maintenance program, all too often the air filter program is overlooked and low quality air filters are used. The air filter protects the most important part of the HVAC system, the heat exchange surface – the evaporator coil. Air bypass, or air that does not go through the filter due to gaps between filters, at the top and bottom and improperly installed filters cause the evaporator coil to become fouled with dirt and debris. This causes the equipment to consume more energy, work harder and shorten its life. Department of Energy studies have shown as much as a 30 percent increase in energy consumption as a result. best PrActice: When the proper air filter is installed and serviced on a consistent basis this can be prevented. The air filter should be at least a MERV 7 according to ASHRAE standard 52.2. The MERV rating is the Minimum Efficiency Reporting Value or the particle removal capability using particle size and worst case performance over a filter’s operational life. The higher the MERV rating the better it will be at removing particulate from the air stream. The best filter type to use should be a continuous pleated filter which goes from edge to edge of the filter track and the media should be oversized to effectively create a gasket seal around the entire filter rack. This seal eliminates air bypass, allowing equipment to run cleaner, in turn making it less susceptible to failure related to inadequate air flow and heat transfer. Time between filter services will vary between 30 and 120 days depending on the application. Most often, a 90-day cycle is employed for filter service. However, the determining factor is the pressure drop that occurs as the filters become loaded with particulate. Refer to the specifications for the type of filter used to determine the frequency. results: With proper air filtration and a global preventative maintenance perspective, savings as high as $.04 per square foot can be achieved for energy alone, the life of the HVAC equipment can be extended and the time between evaporator coil cleanings can be increased to three to five years. Taking all of these factors into account will produce results that save money. 2012 Best Practices | 115 http://www.prsm.com/bestpractices
