GYM at a basement: Latent load
GYM at a basement: Latent load
(OP)
Hello:
I have to design an AC system for a gym.
There's no significnat sensible loads from outside, only from the people.
According to my calculations I have a SHT at design condition of 0.28. Coil load is about 15kW.
At part load, SHF can be as high as 0.9(few people in the gym, and not much sensible load either).
Is it possible to manage this situation?
All help will be wellcome
thanks in advance

RE: GYM at a basement: Latent load
• Are there minimum make-up air requirements and what are they based on?
• Are there exhaust air requirements?
• What are the outdoor winter and summer design conditions?
• Latent and sensible loads from people working out?
• Lighting load?
• Any other heat loads?
• Anticipated occupancy?
Please review these first. Answer: yes, there are numerous ways to manage this situation, but you should first be trained before you design HVAC systems.

I don't have senior collegue I can work with, otherwise I woudn't had posted the question. And yes I am green in HVAC business. The fact is I am not ashaimed to admite it.
After all, all we were "green" at a certain time in our lives weren't we?
SLBforever,
Always ready to learn...

No I don´t have any senior collegue I can work with.Otherwise I woudn´t had posted the question. And yes I am "green" in the matter.The fact is I don´t have problems in admite it.
After all, everydoby is "green" at a certain period,is it noot?

I post the design parameters in SI units.
If you want I‘ll do the conversion and repost the values.
I have done a search in the Web and I found a Carrier Rooftop 48/50 HJ with a Humidi-Mizer module, witch is exactly what I’m looking for, however I still don’t know if this unit is not sold where I live (Portugal, in Europe), but probably won’t.
Any experience with this unit?
Area_____________85m2
Floor height________3,2m
Volume__________272m3
ACH____________8
AHU flow________2176, say 2200m3
People(max)__________25
Outside Air requirements: 35 m3/person=875m3(fixed)
OA/SA=40%
Latent load per person______300W
Sensible load per person____160W
Design parameters (worse case cenarios)
Outside Condition-1-
Peak Dry bulb temperature :34ºC
Humidity at Peak Dry bulb temperature: 25%RH
Outside Condition-2-
Peak Humidity: 85% RH
Dry bulb temperature at Peak Humidity: 22ºC
Other internal loads:
Ligthning____3000W
Others_____300W (tv sets and Gym Machines)
I’m still doing the numbers about peak conditions 1 and 2.
I’ll post the complete load calculation when I’m finished., but for now early comments will be appreciated.
Sorry about my english…
