Overview
Rhvac is available in both an online and desktop version. The desktop version has a one time fee and works on all Windows computers. Rhvac Online is subscription based and works on all computers, tablets and smartphones with internet connection. The online and desktop versions can import and export project files between each other. Both versions calculate peak heating and cooling loads (both block and room by room) for residential buildings and some light commercial applications in accordance with ACCA Manual J, D, and S. Both versions of Rhvac include a complete ACCA Manual D duct sizing capability and a complete Manual S equipment selection. Data can be manually entered or automatically taken from a floor plan drawn with the optional Drawing Board program (available only within desktop Rhvac). The Heat Transfer Multipliers (HTM values) for all the walls, windows, doors, and roofs listed in Manual J are automatically looked up by the software as needed. Additional construction materials are easily added as well.
Design weather data for over 2,000 cities is built into the software. In addition, the user can revise the existing weather data and add more data as desired. Drag and drop zoning control is provided through the powerful and graphic Project Explorer feature of Rhvac Desktop. Zoning CFM adjustments are automatically handled by the software as needed. Equipment can be selected from AHRI databases that are included at no extra charge. Comprehensive reports list the general project data, equipment information, total building load summary, detailed room load calculations, and a room load summary for each zone and system complete with heating and cooling CFM values. Color graphic bar graphs and pie charts can be printed as well (Desktop Only). Other features in both Rhvac versions include glass shading, ventilation air, equipment loads, and default room data. Advanced features in Rhvac Desktop include complete rotation or mirroring of the entire building, and the ability to share data with Bill of Materials, Energy Audit, Proposal Maker, EnergyPro, Energy Gauge, REM/Rate, Ekotrope, REScheck, and Energy Star.
