Heating and Air Conditioning – Variable speed fan motors are designed to eliminate the energy losses associated with heating and cooling systems cycling on and off. Variable speed fan motors increase homeowners comfort and also can help a homeowner save quite a bit on energy consumption related to heating and air conditioning the home.
Utilizing only 1/8th of electricity in comparison to traditional motors, variable speed fan motors accomplish this at 50% of full speed. Variable speed fan motors operates at variable speeds in order to provide greater energy efficiency all the while maintaining the comfort levels in the home. With fixed speed fan systems a heating and cooling system will not be able to operate at optimum energy efficiency. Below we will go over the differences associated with the functions for a more in depth look and understanding of the operations and the benefits.
First off, not to confuse a variable speed fan motor with a three speed motor we will go over the differences between these two. A three speed motor has 3 preset speeds for the fan to operate on such as high, medium and low. A three speed motor contains a circuit board that will dictate the speed based an analysis of the home’s indoor environment. With a three speed motor the system will always perform at one of the three speeds, regardless of whether or not the speeds are too fast or even too slow.
However, a variable speed fan motor can operate at 0 RPM all the way up to full speed. It will operate at the RPM that its circuit board will analysis and dictate based upon the home’s current indoor environment. Whether that speed is 0, 5, 10, 50, or 500 RPM, you will receive exactly what your home requires and not a single RPM more or less in order for your home’s heating and air conditioning to provide optimal energy efficient comfort levels.
When a heating and cooling is removing heat from the air in order to lower the temperatures in the indoor environment it also has the job at removing moisture from the air also. When an HVAC system’s fan is running at fixed speed on its fastest setting all of the time it will actually result in more heat and less moisture being removed from the air. Variable speed fan motors will be able to handle both effectively, by turning the fan down to a slow sped when the air compressor first turns on, allowing for the humidity to be extracted from the air. While the humidity is being removed, the air conditioning coil will cool the air that moving over it, which will cause the blowers speed to increase and send the cooled, conditioned dry air throughout your home.
When balance is achieved between both humidity and heat, the fan motor will run lower. However, the typical fixed-speed motors will run at high speed, which will allow for the air to retain the humidity and reduce comfort. When a variable speed fan motor is installed, when the air conditioning first turns on, the fan motor will simply run slower in order to extract all of the moisture from the air. When the indoor relative humidity is reduced to a more appropriate level then the air coming from the vent registers will be cooler and the force of air being delivered from the registers will increase.
When there are excessive amounts of humidity in the indoor air, it makes it harder for that air to be cooled and will cause heating and air conditioning systems to run more often with fast blowing motors that are just not capable of removing the indoor relative humidity properly. Humidity makes the surrounding temperatures seem hotter than it truly is due to the moisture in the air and on top of that excessive humidity can also proliferate the growth of mold and mildew. A variable speed fan motor will solve most of these problems by limiting the air flow throughout the home until the excessive moisture has been removed from the indoor air.
When it comes to savings in electricity, a variable speed fan motor cannot be beaten. When a variable speed fan runs at half speed at 8 hours it is the equivalent of a full-speed motor running for only 1 hour.
