Good day engineers!
I am Nelson from philippines and currently studying in Mapua Institute of Technology taking up
Mechanical Engineering. My group mates and I have a project in our Industrial Plant Engineering,
and the design that we are supposed to do involves HVAC. But our instructor doesn't teach us
enough about the HVAC. We are having a hard time finding books or references like ASHRAE
fundamental, application etc.. We searched the net but we are not convinced that all of it are true
(or maybe we just dont understand it that well hehehe). Then someone we know told us that it is
better to learn in online forums where experienced engineers gathers and share knowledge. So
we hope that you guys can help or guide us in what we are doing or just check if we're doing it wrong.
Thank you for your time
Ok, so what is it that you are doing...whats the HVAC project?

Welcome to the forum!
We like to hinder, I mean help...
I r the king of the world!...or at least I get to stand on the roof and look down on the rest of yall
Man I wish i had a dollar for every time i was at a system and said "I wish I had the engineer here that put that there." Welcome to the Boards.
It`s better to be silent and thought the fool; than speak and remove all doubt.
Not for sure but I bet its not the same as a noob job
You should take your dog to a vet.

many thanks for the welcome! just got back from school.. hmmm its a 20 storey building, it has a commercial area, clinic, gym on lower floors and residential on upper floors. We are planning to use and air handling unit in lower floors then use window or split types in the residential area.
Perhaps the info you need to find first is how to make heat load calculations for commercial structures. This is important because you need to determine the correct capacity for whatever kinds of systems you choose.
Even in the Philippines, you should be able to access academic sources for that kind of informations. Perhaps the University at Sydney Australia could be a help to you.

Yes we'll make the heatload calculation first. we're using the CLTD method in determining out heatload. but since our time is not enough our professor told us that we can use manual calculation on different exposure and occupancy of the building but not all since it would really take some time. so he recommended to use the area method like square meter per ton on different occupancy. After we compute or heatload can i ask for some assistance on selecting equipment? I really think its more than just matching your tonnage and cfm.. i dont know but i guess there's much more correct selection. Thank you guys for helping us! We really appreciate it. *and I'm sorry if im not always online, but I'll visit this site when I got home from school* Thanks again
