VAV design guide

VAV design guide

VAV design guide

Could anyone familiar with VAV design recommend a book basic guide that I could download or purchase? Something that starts with the basics and goes from there. Thank you

RE: VAV design guide

You should try manufacturer sites, ie, McQuay, Trane, Carrier and etc.

RE: VAV design guide

Depending on how advanced you are, read this
how much do you already know?

RE: VAV design guide

Thanks for the suggestions and link. I know the engineering fundamentals (I have an EIT and PE), but have been out of the business for awhile and have never designed a VAV system before so I thought I review some basics. I am reading that URL you posted energyprofessional which looks to be a very good overview.

RE: VAV design guide

Perfect, thanks

RE: VAV design guide

Have you read the ASHRAE manuals on the subject?

RE: VAV design guide

Excellent material!!

RE: VAV design guide

interesting thread..
thank you sir, because i interesting to know too..thumbsup2thumbsup2

RE: VAV design guide

hi all,

i found there are many material talking about the method to determinate the min flow of the VAV boxes.

However, may i ask why there is a non-zero min flow required for VAV? (although i know that there are zero min flow VAV in the market). is it only because

1) to prevent overheat/damage to the heaters, so to keep manufacturer's recommended min flow rate?
2) to keep min flow just because of to keep min ventilation rate and thus better IAQ? to my understanding, flow rate should vary according to thermostat to maintain required temperature and thus no need to be non-zero min flow rate. in order to keep better IAQ, the VAV should vary according to the CO2 sensors and thus also no need to be non-zero min flow. however, i found most applications have non-zero min flow rate. why?
