Hey guys, I'm currently studying topics about HVAC before I try to get a job as a mechanical engineering designer and I'm currently interested in learning about the different electrical engineering aspects in HVAC, specifically the ones that would be useful for an ME designer to know. For the ME...
So, I recently found out that the power that a motor has and uses are two different things (from what I understand). So the input power of a motor is electrical power, using the equation P = I*V, and the output power is mechanical power, which can be calculated using the equation P =...
So, I've been reading this paper from Carrier in regards to the application of fans in commercial HVAC Equipment (Link to White Paper below) and I have a few questions regarding system effect. First, here is a following excerpt from the paper (Page 6), saying,
"Since the velocity profile at the...
So, the above figure, is almost the same figure that is shown in the 2016 ASHRAE Handbook - HVAC Systems and Equipment (Page 21.4) with Total Pressure being defined as the fan total pressure at the outlet minus the fan total pressure at the inlet. This figure is shown in the handbook when it's...
So, I'm trying to learn what's done in the Mechanical Engineering HVAC Industry in regards to selecting a blade type for a fan. I've looked at Table 1 for Types of Fans in the ASHRAE HVAC Systems and Equipment Handbook and there it talks about the different blade types (airfoil, backward curved...
