    Heat Loss/ Gain Calculation

    Thank you all for your response. I know it's easier to do it on the computer and it's automatic..BUT sometimes it's nice to get it and learn it how did that 'value' comes out. Rather than just punching it in the keyboard. Lots to learn! Thanks again

    Heat Loss/ Gain Calculation

    It might be a funny question but here goes..I'm just curious, how do they do the heat loss calc back when theres no computer or software. How do they do it manually. I ask someone, and says 'you can only get the value on the computer, it calculates it for you'..and i say, is there a way to do it...

    Reduce cfm

    Sorry, so replacing the unit to a lower cfm is not an option because the owner doesnt want to spend. My question remains, is there a way to reduce the cfm? can you adjust anything? can you add something to the unit to reduce it's cfm? can you redirect the air? I'm NOT really sure, I'm new to...

    Reduce cfm

    Actually its 4 point something. To round it off, it will come up to 5 ton. It's actually inside the shopping mall, so there's no exposures. it's only a typical retail space with minimal lighting and equipment.

    Can't wait to be an HVAC/r expert

    It might be a bit optimistic to mention the word 'expert'..pardon me. Anyway, I'm new to the HVAC world and I'm working in a engineers office doing hvac and plumbing. And to tell you the truth, I liked it! I'm just thinking is there somebody out there who knows a school in Ontario...

    Increase cfm

    The unit is a shell space with roof top unit. The base building engineers assume that whoever occupy the space, 12 ton would be enough. So to answer your question, I'm going to say no.

    Increase cfm

    I'm working on a retail space and heres my prob. the heat loss calc comes up to 14 ton. The existing roof top unit only has 12 ton. The client doesn't want to add anymore ac units to cover the required 14 ton. Is there a way to increase the cfm to 14 by just using the 12 ton. sorry i'm new to...
