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.
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.
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
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?
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.
@@passionateengineer04 thanks for reply. i have done the same but didn.t find any information in HAP report regarding the negative pressure. kindly make a dedicated video for design of negative pressure rooms in HAP.
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.
@@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
@@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.
Group A: In or near ceiling, horizontal discharge. Group B: In or near floor, vertical non-spreading discharge. Group C: In or near floor, vertical spreading discharge. Group D: In or near floor, horizontal discharge. Group E: In or near ceiling, vertical discharge.
@@passionateengineer04 Sir can you share with me your ductwork in sad micu and isolation room just for my understanding that sir how you done ductwork please sir share with me that will be your kindness❣ my email sir👉 faisalhussain8899@gmail.com
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.
Hello sir, I have a final year year project on HVAC, can you plzz give me your nmber, i want to discuss my project that how i can strt it, i will be very thankfull Thank you
@@passionateengineer04 thank you so much for your valuable reply sir can please give me the clean room design related books and excel file ( heat load with pressurisation) at nalavadegaurav@gmail.com
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
