Discuss methods for dealing with frost formation on blower air filters in winter
Thread Content
The air filter of the furnace blower tends to frost over in winter, resulting in negative pressure in the furnace and fluctuations in oxygen levels! I welcome all experts to share their ideas and discuss this, in the hope of finding the most ideal solution!
A coarse mesh is installed at the inlet perimeter to trap some water vapor molecules. Connect one from the fan outlet to the suction chamber, create an outward-facing porous nozzle; it’s advisable to install a self-controlled solenoid valve to perform reverse blowing of the filter at regular intervals. Typical filter systems are set up in this way, with an additional layer added on the outside for coarse filtering or for manual cleaning at regular intervals. The key is that the humidity in the surrounding area is high. I’m not sure about your filters; it’s better to have two sets. If the resistance is too high or the moisture content in the filter screen is too high, it is necessary to replace it and switch to using another one. For reference.
Either add electric heating or a steam coil!
