(cfm) measures the volume of air that flows through a space in a minute. in hvac, cfm airflow is important. it helps determine the correct size and capacity for your air conditioner, heat pump, and furnace. your hvac system heats, cools, and moves air - that’s what the v in hvac...
A computer's internal fan may be rated for a particular CFM to guarantee specific cooling performance, for example, to handle overclocking and other situations where internal computer temperatures may rise significantly. In some ways, this is similar to the use of CFM in HVAC systems, except ...
If you tend to cook quickly, choosing a lower CFM model might make sense. On the other hand, if you like to spend long hours preparing meals or do heavy cooking, you might want to invest in a high CFM range hood. Quality of ducting Smooth metal ducting is the most popular type of d...
Does anyone know what happened to the "Tim's HVAC Tools" shareware program? It was a neat little bunch of HVAC calculation tools but when I go to the website to download it, I get one of the web hosting messages that that site is no longer available. Does anyone have a copy of ...
I’ve just scratched the surface of this topic here. And as you can tell, it’s a tricky subject. But doing it right in the HVAC design process doesn’t ensure you’ll have the correct air flow. How the unit is set up by the installer can make a difference. And how well the duc...

Sizing a heat pump seems like a daunting task. How do I calculate what size heat pump do I need? How many BTU heat pump do I need? This is usually an estimate that you need an HVAC expert for. We are going tosimplify how to calculate what size heat pump do you need. That will ...
Is HVAC Mold A Common Problem? Since mold is frequently found in household dust, your HVAC system's interior will always include some mold. However, it is not typical nor desirable for there to be visible mold growth on the inside of your system or your ductwork. This is almost always br...
mean the PSC motor will be steamrollered out of existence. Barely able to convert a paltry 65 per cent of its electrical input into mechanical work, PSC motors suffer from asynchronous alignment, that is, the rotor constantly lags the magnetic field in the stator. Known as slippage, it mean...
Anthropogenic climate change is increasing the risk for devastating wildfires [1]. Over the past thirty years, the area burned by forest fires in the western U.S. has nearly doubled due to drier forests [2]. About half of the observed increase in length of fire season and days with high...
