However, Rhvac Online cannot show as much information on one screen as does Rhvac Desktop, and you must be connected to the internet when using Rhvac Online. The ideal situation is to have both Rhvac Desktop and Rhvac Online. In this way, you can work on the same projects in the most efficient way possible no matter where you are.
Use Rhvac Online when you are out in the field and you want to do a quick load calculation on your phone or tablet or just the check over a project you have already done on your office computer. And later, access that same project on your computer at home with a large screen and keyboard using Rhvac Desktop.
Rhvac Online gives you the ability to do projects completely from scratch or just review and edit projects you have already done elsewhere. It 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. Rhvac Online is extremely handy to the HVAC professional that wants all his projects available to him at all times, along with the ability to review, edit, and calculate new results.
Included at no additional charge in Rhvac Desktop is a Quick Sales Proposal option that is primarily used to create basic sales proposals. This option is very simple to use as the designer merely checks boxes to indicate what information to include in the proposal. Standard proposal text can be saved and selected to print as well. The input window shown here shows the simple inputs needed to create the sample proposal shown after the input screen.
The report shown here is produced from the Quick Sales Proposal window. The basic sales proposal is not currently in Rhvac Online, but may be added in the future if sufficient demand exists.
Proposal Maker gives you complete control over all aspects of a proposal's appearance. Graphics and text can be mixed in any way desired. This kind of customization capability requires more user input than the built-in basic proposal of Rhvac Desktop, but for those wanting the most professional appearance possible, Proposal Maker is the way to do it. See more details and sample proposals here.
Used just with Rhvac, a designer can select from thousands of parts and equipment items to create a detailed bill of materials with both material and labor cost estimates. If Drawing Board and Graphic Manual D Ductsize are also activated, the BOM module can do automatic material take-offs from Drawing Board drawings which is especially useful for picking up ductwork items. Bill of Materials is not available for Rhvac Online, but may be offered in the future if sufficient demand exists.
The Bill of Materials module is very powerful in that it can import material lists from virtually any supplier so that you can add thousands of new items easily at anytime. In addition, the reports are completely customizable with over 70 columns of data that can be turned on and off as needed. Know your true costs for all your projects so you can profitably price your work.
See more details on the Bill of Materials module here. These data cover nearly 2 million models of standard air conditioners, heat pumps, ground source heat pumps, furnaces, and boilers from over HVAC manufacturers. These data are updated every few months, and Rhvac automatically downloads the new equipment data files as they become available. There is no cost to Rhvac users for the updated equipment data. Click here to read more about expanded ratings data and where you can obtain it.
Model data and pictures can be selected to appear in the reports for each system of an Rhvac project. Some projects require selecting equipment using more than just the nominal ratings as obtained from AHRI model data.
Manual S is an ACCA publication that describes how to select properly sized residential heating and cooling equipment for all types of situations. 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. It 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, whether the cost of cooling or heating is of more concern, and whether cooling comfort, heating comfort or efficiency is the most important consideration.
Manual S explains how to utilize important techniques such as converting latent capacity to sensible capacity when conditions allow for it, and includes rules for allowed oversizing percentages that vary according to climate and type of equipment. Both Rhvac Desktop and Rhvac Online provide the ability to interpolate from expanded ratings of equipment and create an Equipment Data report showing Manual S selection parameters and a Manual S Report that certifies that all equipment has been selected per Manual S requirements.
This report also shows all the associated conditions needed for obtaining specific model performance data from expanded ratings data. Many states, counties, cities and townships around the U. The International Residential Code IRC is a comprehensive, stand-alone residential code that creates minimum regulations for one and two family dwellings of three stories or less.
It brings together all building, plumbing, mechanical, fuel gas, energy and electrical provisions for one- and two-family residences. The IRC also provides a prescriptive approach i. The International Energy Conservation Code IECC encourages energy conservation through efficiency in envelope design, mechanical systems, lighting systems and the use of new materials and techniques.
Each state has its own energy code requirements. Rhvac helps you comply with state energy codes by creating input files that energy code compliance programs such as ResCheck, Energy Gauge, and RemRate can import. The advantage of this feature in Rhvac is that you do not have to reenter the data over again for any Rhvac project that you wish to use in one of the above energy programs. Many states have code laws that technically cover the entire state, but are often not enforced in certain areas of the state simply due to lack of resources.
Some contractors take advantage of this lack of enforcement and disregard various code points as they believe there are no potential repercussions from doing so. While it is true that no immediate penalties are likely to occur in a low enforcement area, it is quite possible that some future problem with the building will arise that causes the owner to investigate details of the installation.
If the investigation, even done years later, determines that various points of the governing state code were flagrantly ignored at the time of the installation, a Mechanical Integrity violation could be invoked causing significant fines and penalties. The Mechanical Integrity concept is a general requirement that a contractor follow all applicable standards in the performance of his work relating to equipment, piping, instrumentation, electrical systems, and other physical items.
Contractors who ignore their state's own implementation of the IRC and IECC codes, no matter how laxly enforced, run the risk of a future Mechanical Integrity violation. As mentioned above, both versions of Rhvac provide nice built-in equipment selection capabilities. But if you need to compare one specific model or a type of model against another and perform an economic analysis of operating costs, then the Energy Audit program is what you need.
It can import all necessary data from both versions of Rhvac or be used stand alone. By calculating pay back and return on investment, Energy Audit is perfect for showing your customers why high efficiency equipment is worth paying more for. See more details on Energy Audit here. Ground source heat pumps and direct exchange heat pumps that use geothermal energy are the most efficient HVAC units on the market today.
The U. Rhvac calculates perfectly for all types of geothermal equipment. What is different about ground source heat pumps is that a "loop" design also needs to be performed. A loop is usually polyethylene tubing that is buried in the ground or submerged in a pond. This loop connects the heat pump to the ground or water. The length of tubing required in the loop is a special calculation. Elite Software offers a program called ECA Earth Coupled Analysis for the calculation of ground loops in horizontal, vertical, and "slinky" configurations.
ECA can import all necessary data from Rhvac or be used stand alone. See more details on ECA here. Direct exchange heat pumps use copper tubing to connect the heat pump to the ground.
