Same bro. His offline video class helped me to work efficiently without asking help from my senior hvac engineers in my company. I wonder why one should choose other mep institue if AMNEAR is there.
Great Explanation I would like clear one point. what will be the total cooling load tonnage from (36 to 13 deg c) & (36-24) As per my estimation it is arround 7 ton & 5 ton respectively. could you please confirm this
Thanks for your support. Delta T alone is not enough to determine the tonnage. Your question needs clarification. Are you asking for the tonnage required to reduce the temperature of a specific quantity of air from 36°C to 13°C? If so, we need the mass flow rate of air to calculate it. Alternatively, if you're asking about reducing the temperature of a room, we need to calculate the room's sensible and latent cooling load to determine the tonnage. Delta T by itself cannot provide the tonnage of refrigeration.
@@amnearmep Thanks for your reply I was considering 400 LPS fresh as per your videos 400 from 36 to 13 400 from 36 to 24 outdoor air without recirculation (100% Fresh air)
If the temp.and RH of air at machine outlet is 24C and 50% then what will be the temp.and RH of air at diffuser outlet? Suppose inside design condition is same as air at machine outlet.pls clear it.
Hi, ITS SAME. In practice, as the air travels through the duct system, there may be a slight increase in dry bulb temperature due to heat gain in the ducts. This gain is sensible, meaning it won’t change the humidity ratio, only the temperature. So, a small increase from 24°C may occur. Since we are already considering duct heat gain allowance while doing the heating and cooling load calculation, its not an issue. If the air leaving the cooling coil is at 24°C and 50% relative humidity, ideally, the air leaving the diffuser should also be at 24°C and 50% RH.
Well explained.
I had already learned this in your class, once more thank you for sharing this valid information.❤❤❤
Thanks alot dear for your support❤

Sir can u please do smoke ventilation calculation ..?
Please..
@@Alex.p-oo1xw Noted. It's already included in our course. But, didn't upload in youtube. I will do that in future.

it can slightly more that 24 due to sensible gain.
