HVAC engineer development
1st of all, I would like to mention that I am glad to find this great website. I am a Mechatronics Engineer, during my degree program, i had couple of courses of Refrigeration and air conditioning systems + load calculations.
Now I would like to focus on HVAC engineering, so Im seeking for a guide to a start point from zero. In order to be an HVAC engineer and maybe a certified one, whats the best approach to develop myself, resources to read, courses or training.
The reason I wanted to focus on HVAC is because a friend has an engineering company and we would like to start a new activity which is air conditioning design service for residential as a start and then maybe light commercial.
I appreciate your co-operation. Waiting for the experts ..

residential? lol, get real, you will go broke
Hey, as i said it is a start for me to develop myself technically + there is a high demand on ACs for residences in my country since today is 48 degrees celcuis
Residential systems usually don't require engineering expertise. Any half-decent resi tech should be able to design and install a proper solution. Industrial-Commercial-Institutional is where you wanna be. Already being a mech eng is a huge leg up, but you will need to take some additional courses to develop a proper level of understanding for the subject. Here's a good resource to get you started http://www.youtube.com/playlist?list...5&feature=plcp
here in the US HVAC techs use ACCA manual J for residential load calculations, books and software can be purchase from the website: https://www.acca.org/store/
As you know unlike the rest of the world we here use crappy inch-pound/Fahrenheit units, dont know if the ACCA has the manuals in metric units.
in my country, the demand on residential applications is very high, we need the AC mostly even during winter. I understand that I need extra training and this is I posted this thread to know where to start from. I will check the link you provided.
I appreciate it, Thanks
Thanks for the link. I did the calculations based on ASHRAE standard in college, which uses the same units you mentioned (PI).
Ahmad, the demand may be high, but for resi applications, it's already been engineered at the factory. The technician runs the air distribution system (if there isn't a decent one in there already) based on established best practices and installs the equipment. If you wanna get in on the technical side of it, great.. We could use more engineers willing and able to get their hands dirty without making a mess of things. I'm just telling you that there is precious little engineering work done in resi applications and it's usually done by the manufacturers and techs.
One resi scenario where it pays off to hire an engineer: When you're doing lots of identical units, like a townhouse complex, as a package deal, that's when the builder can save on space/equipment/materials if an engineer gets in there and starts tweaking the design.
Need to get into duct design. A lot of installers don't give a crap about good air distribution. Manual D tells how to do it. ASHRAE Fundamentals Handbook 2009 Edition is even better. Get them and become an ace on proper air distribution / duct design and that should help you a lot along with load calculation which ASHRAE covers in the same book. Manual J is great but I like ASHRAE method in chapter 17 of Fundamentals book even better. Good luck

what kind of residential HVAC systems are predominant in your country?
the middle east has a love affair with mini-splits,VRF etc.
You are right, there is a huge demand on split-duct AC systems and Central AC.

We have big families that live together and build big villas, and they demand package AC systems and split-duct system. For townhouses complexes in some areas, they tend to use chillers and then of course ducts for air distribution, especially air cooled chillers.
thanks and regards .
I have studied some duct design, from the aspect of sizing. I had practices calculating the required size during my college course. I Agree with you, air distribution is critical, as calculating the cooling load required is not enough.

Yup I agree 100% with you, the residential projects is the target as a start as you mentioned, the townhouse complexes which is so popular and increasing in here
