Thanks alot man this video is so helpful and I learned many things from it 🤔🤔🤓🤓

[@ManojSharma-gu8re]

Sir, can we get the revit arch model of this drawing for practice? Or any other model for practice?

[@muntekimgicirbey]

Hi, again many thanks for your video. I have a question about the software. I want to see the effect of filtration like HEPA filters on energy consumption of the HVAC system ( mostly pressure drop related energy consumption). Is it possible to do with this software? If not, do you have any suggestions?

[@yokeleetan8525]

sorry please check your input data and definition. you only input the walls if your walls are external walls exposed to sunlight. for internal wall, please use partition. and floor above conditioned space means that your calculated room is above another room which is conditioned to same room temperature.

[@passionateengineer04]

Yes, you are right but these are only just examples. Select wall that are exposed, it depends on orientation of building. For internal walls you will use partition walls and fo roof also.

[@JWu-jt7fz]

Exactly that's what I was thinking when I saw this

[@johneziekelcagape5694]

Hello, very informative. CAn i ask where to find the sofware that you used for cooling load calculations?

[@passionateengineer04]

HAP 4.9 or 5.1 can be downloaded from internet for free

Sir, ideal place of HVAC department in Hospital ? which floor? can i keep it at basement ?

Nee ductless AHU systems ...are they NABH accredited?

[@passionateengineer04]

Yes, if it follows guidelines. Do you want to use it in OT?

[@SonuChoudhary-hd9sg]

I think there is some problem in this video regarding that and window exposure in its properties you expose all 4-side wall how???

[@passionateengineer04]

It's just for calculations.all depends on the building orientation

I have a question, you defined room one as zone 1, is that correct? also how could I gain access to the software, is there a free download, or a website where I could purchase a membership? Thank you so much this has been so helpful, I'm a mechanical Engineer in NYC and I'm working on a project to design a HVCA system for a two story house....Thank you again for the video and the help

[@muzaffershaik8336]

Sir. in HAP software, Equipment class: Hygienic units not available plz tell me how to add

[@passionateengineer04]

Can you please guide me why you want to add a Hygienic unit in HAP? Because AHU is enough in system data for cleanroom and others. If your country have high humidity in some seasons than you have to calculate load on that temperature in which humidity is high, else you can use dedicated software for load calculation of cleanroom and healthcare facility.

[@muzaffershaik8336]

@@passionateengineer04 sir in our country we have high humidity and i am doing calculations for Health care facility (veterinary clinic) (Rooms , Surgical, Pharmacy, and Examination/Treatment rooms) for that i need to select hygienic units

[@passionateengineer04]

@@muzaffershaik8336 you need to calculate load at high humidity, e.g in August humidity is high, so you need to calculate load on these parameters not on ambient temperature. Once you get the load, then you need to select hygienic AHU based manufacturer selection.

[@Shamiyusif]

Why u are considering all 4 wall? , you need to consider the wall facing outside and other wall shall be partitions wall if it is not air conditioned

[@passionateengineer04]

It depends on your building orientation and exposure, if 3 walls are exposed than do calculation for these 3 walls and consider 4 th one is partitioned space or you can only do calculation for 3 walls only. in video these are just examples everyone have different scenarios.

Hi bro,I'm go with fcu So what I select air system type?

[@passionateengineer04]

Fcu is not suitable for hospitals, or you can use ducted type with filter bank.

[@sonao4201]

in Patient room, why outdoor ventilation air =0 , SA=280 CFM, it means using 100% RA, I seen you input= 23 CFM but result =0

[@passionateengineer04]

Yes, you right, i think it was mistakenly removed, during video recording. You can follow the procedure by yourself, i was teaching the method to do such calculations

[@abidmohd006]

Why did you give 100 percent ventilation when it was asking only 15 percent extra exhaust?

[@passionateengineer04]

15% extra exhaust mean you have to exhaust 15% more air than supply air.

[@abidmohd006]

PASSIONATE ENGINEER yes but you gave 100 percent ventilation there

[@passionateengineer04]

Yes but we do that in excelsheet later, like once we get the total exhaust cfm we add 15 per more

[@crazycontroller7751]

Kindly explain how to design a room with a negative pressure in HAP.

[@passionateengineer04]

Negative pressure means more exhaust than fresh air, you need to account for 100% fresh air and put direct exhaust cfm in the thermostat option. This way you can calculate load for negative rooms.

I will try to upload a video on this topic
