Manual S Online Calculator
Elite Software’s Manual S Online Calculator is a web app that works on all smartphones, tablets, iPads, and computers with internet access. It performs ACCA Manual S HVAC equipment selection calculations and references over one million models of for all manufacturers listed with AHRI. The Online Calculator provides the ability to interpolate from expanded ratings data of HVAC equipment and creates a Manual S Report that certifies that all equipment has been selected per Manual S requirements.
HVAC equipment manufacturers provide their performance data in numerous different formats. The Manual S Online Calculator handles all the different manufacturer data formats and is flexible concerning what data items are analyzed. In the most complex case, performance adjustments are made for outdoor air dry bulb temperature, air flow CFM, entering dry bulb temperature, and entering wet bulb temperature.

Background Information on the ACCA Manual S Procedure
Manual S is ACCA’s procedure for the optimal selection of HVAC equipment. It emphasizes the importance of using performance data sometimes called “expanded ratings data” that document the sensible, latent or heating capacity of a model for a wide variety of operating conditions. Manual S suggests sizing strategies that differ according to the type of equipment being used. And it provides steps for these different strategies that involve things such as considering whether the latent load is large or small compared to the sensible load, whether the cost of cooling or heating is of more concern, and whether cooling comfort, heating comfort or efficiency is the most important consideration.
Rhvac Online provides the ability to interpolate from expanded ratings data of equipment and create a Manual S Report that certifies that all equipment has been selected per Manual S requirements.
When evaluating Manual S software, it is important to review the flexibility of the software concerning how expanded ratings data are handled. HVAC equipment manufacturers provide their performance data in numerous different formats. The best Manual S software is designed to allow for all these variable formats.
Not only should Manual S software handle all the different manufacturer data formats, it should also be flexible concerning what data items are analyzed. In the most complex Manual S case, performance adjustments are made for outdoor air dry bulb temperature, air flow CFM, entering dry bulb temperature, and entering wet bulb temperature. The Manual S Online Calculator allows for all of these variables or any combination desired.
