Etan Energy announces a new combination technology that reduces both air conditioning and heating cost up to 29% with an average of 15% for small businesses such as restaurants, office buildings, and auto dealers. According to the Department of Energy, up to 55% of total energy costs for businesses come from HVAC Systems.
Using a dual microprocessor called the HVAC Smart Chip Plus, Etan Energy states they are able to reduce energy costs by extending the HVAC fan cycle for a longer period of time after the heating and cooling cycle is complete, thereby capturing latent heating and cooling that would have otherwise dissipated. Most manufactures of HVAC systems have no fan delay, or one of an additional ninety (90) seconds. Recently, a California Energy Commission (CEC) study of the HVAC Smart Chip Plus, conducted by Pacific Gas and Electric, revealed that a longer fan cycle yields better energy efficiency.
The HVAC Smart Chip PLUS utilizes a simple retro fit and has dual microprocessors that operate in both heating and cooling modes. The first microprocessor monitors system cycle time and adjusts the HVAC fan to stay on for an extended amount of time after the cooling or heating unit cycles off. Most systems are designed for the fan to turn off after 60-90 seconds. The chip records how long the cooling or heating unit has been running and, using that data, automatically programs the fan to remain on for a precise amount of extended time. According to the CEC study, this extra fan run time helps utilize additional hot or cold air left in the system that would have been wasted and subsequently reduces the number of times the HVAC systems cycles on/off.
The second microprocessor is designed to monitor and manage the compressor run time. For all systems cycling 30 minutes or greater, the chip will automatically schedule a 5-minute reprieve for the compressor, allowing for maximum benefit without additional wear and tear on the compressor, producing additional electric bill savings, says Etan Energy.
According to a spokesperson for the company, their goal is to provide “better system efficiency, no wasted energy, and reduced utility cost all while maintaining the comfort of the environment”.
