National Comfort Institute New Knowledge Base Questions
Access Level: NCT Member Only
Question Category: Air Diagnostic
Question: How can I measure air volume on a system with a 12-inch air sock as the duct? The customer has gone through 2 heat exchangers in three years.

Question Category: Testing
Question: Last year a member asked the best way yo charge a heat pump in the heating mood in the winter.At that time jim davis gave an answer to the effect of put a digital thermomater on the discharge line between the compreser and the reversing valve an add 126 degree above ambient temperture. I have serched for this question and answer but cant find it any where this year jim tell me if this answer is still avelable and where can i find it.

Question Category: Technical
Question: Hot air goes to cold and wet goes to dry? right?

Can i have help with calculating what size fan is needed? i don't trust my math just want to double check.Can you point us in the right direction with the math formula? Thanks

Access Level: NCI Online User
Question Category: Heating
Question: Do you have anything in writing I can share with my customer about High Low fire or staged equipment?

Question Category: Test Instruments
Question: I'm thinking of buying a TSI flow hood. It seems that it will read up to 2000 cfm, but I will be reading values much lower than this that may total 2000 cfm. How accurate is it when reading individual 4" to 9" supply ducts that are no where near the high range? Is it more accurate as the volume of air increases or is uniform accuracy across all volumes? I have read where some lose accuracy at low volume levels. I just want to trust my measurements if I fork out that kind of dough.

Question Category: Air Flow
Question: I recently finished servicing a montgomery ward furnace model # SRM54-4345B 80 BTU. The blower had not been cleaned ever. My before static pressure readings were return .016 supply .041 after cleaning the S.P. were return .042, supply .095. here is my question. The before and after delta T remained at 70 degrees. I expected the temp. difference to drop by some amount say 5 degrees? If I'm moving more air across the heat exchanger why did the temp. reading stay the same? Is this usually the case?

Question Category: CO AND COMBUSTION
Question: We have a customer that has a paint booth type oven that fires on natural gas and is interested in having a combustion analysis done on it. Do you have any suggestions?
