Rhvac Online - Manual J Load Calculations, Manual D Duct Sizing, and Manual S Equipment Selection

Rhvac is Elite Software's best selling product. It is an ACCA approved program for Manual J load calculations, Manual D duct sizing, and Manual S equipment selections. Available for many years only as a Windows program, Elite Software is proud to announce Rhvac Online for use on all web enabled devices.

Works on Everything: Rhvac Online is a web application able to run on all internet devices, including iPads, tablets, computers, and smart phones. Rhvac Online is the only web based application on the market today that can do all three code required ACCA Manual J, D, and S calculations.  Rhvac Online has all the major features of the basic Rhvac 9 Windows software that many of you already have.

Does Whole House or Room by Room: You can enter your project as a whole house or as room-by-room. When doing whole house, you simply enter the entire house envelope into room 1.

Rhvac Online and Rhvac 9 Share Project Files: Rhvac Online gives you the ability to do projects completely from scratch, or review and edit projects you have already done with Rhvac 9. Project files can be shared back and forth between the online and Windows version. Rhvac Online can even upload projects that were done graphically and let you review and edit all data that is non-graphic and download it back down as well. Rhvac Online gives you the ability to access all your projects anywhere and anytime you can get on a web connected computer or mobile device.

Unlimited Cloud Storage: With Rhvac Online, projects are stored in the "cloud," and are available to you from any internet connection. Projects can also be saved to your local computer and can be uploaded and downloaded from different computers as desired. Unlimited project file storage is allowed. You can even use the cloud project database of Rhvac Online to store backup copies of all your Rhvac 9 for Windows projects.

Unlimited Free Phone and Email Support: Most online products are minimal applications with pared down features and no support. Not so with Rhvac Online. You get the same unlimited free phone and email support with Rhvac Online as you do with the Rhvac 9 Windows software.

Low Cost: Rhvac 9 has a one time $499 fee, and works on all Windows computers. Rhvac Online is subscription based, and is $239 per year if you don't have Rhvac 9, and only $149 per year if you do own Rhvac 9. See more details here.

Manual D Ductsize Online

Manual D is ACCA's procedure for sizing residential duct systems. The procedure matches duct system resistance (pressure drop) against the blower performance of the air handler or furnace. The total duct system pressure drop is dependent on the roughness of the duct material (galvanized, duct board, flex, etc.), the length of the ducts, the size of the ducts and the duct fitting losses. Manual D software factors in all of these variables when calculating total system pressure drop and optimal duct sizes. A Tabular Entry Manual D is built-in to both Rhvac 9 and Rhvac Online, and a Graphic Manual D option is available for use in Rhvac 9. For those of you who might want a stand alone Manual D duct analysis capability using a phone, tablet, or computer, there is now a low cost way to have this by subscribing to Manual D Ductsize Online. Manual D Ductsize Online uses a tabular input procedure that shows how ducts are connected in an explorer tree format.  This input procedure is shown above where you can either enter your entire duct system or just individual ducts for separate analysis. This unique tool includes a powerful Fitting Selector that makes it easy to select from hundreds of fittings from ACCA's Manual D.

For those who don't need the complete Rhvac 9 or Rhvac Online J, D, and S capabilities but still want a low cost online Manual D analysis tool, Manual D Ductsize Online is the product for you, with only an $89 per year subscription fee. Manual D Ductsize Online is simply Rhvac Online with only the tabular Manual D features activated. See more details here.

Manual S Calculator Online

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.

Both Rhvac 9 and Rhvac Online provide 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.

For those who don't need the complete Rhvac 9 for Windows or Rhvac Online J, D, and S capabilities but still want a low cost online Manual S report tool, then Manual S Calculator Online is the product for you, with only a $49 per year subscription fee. Manual S Calculator Online is simply Rhvac Online with only the Manual S features activated. See more details here.
