The Elite Software RHVAC Program quickly and accurately calculates peak heating and cooling loads for residential and small commercial buildings in accordance with the seventh edition of the ACCA Manual J. The Heat Transfer Multipliers (HTM values) for all the walls, windows, doors, and roofs listed in Manual J are stored and automatically looked up by the program as needed. Although HTM values are taken from Manual J directly, the user does have the option of entering his own U-Value for each wall, roof, or glass section so that a modified HTM value is used. Design weather data for over 1500 cities is built-in to the program.

In addition, the user can revise the existing weather data and add additional weather data as desired. Zoning cfm adjustments are automatically handled by the program as needed. Other outstanding features include exterior glass shading, ventilation air, miscellaneous latent loads, default room data, automatic rotation of the entire building, hydronic heat calculations and much more. Besides calculating peak heating and cooling loads, RHVAC also performs runout and main trunk duct sizing, creates sales proposals and selects hvac equipment. Duct sizing options include all types of duct materials, height and width restrictions, velocity limits, and more.

For equipment selection, RHVAC is provided with a database derived from ARI and GAMA of thousands of equipment models from over 80 hvac manufacturers. Standard air conditioners, heat pumps, furnaces, boilers, and ground source heat pumps are among the types of equipment RHVAC can select. The sales proposal feature of RHVAC prints key features of the proposed equipment and work to be performed. Also included are standard terms and conditions of the proposal. RHVAC shares data with Elite Software's AUDIT operating cost analysis program, DUCTSIZE, Quick Quote, and Drawing Board program. RHVAC can be used stand alone or in conjunction with any of these programs.

CALCULATION METHOD
The RHVAC Program follows the exact methodology described in the Air Conditioning Contractors of America (ACCA) Manual J, Seventh Edition entitled "Load Calculation for Residential Winter and Summer Air Conditioning". Although intended primarily for residential applications, the Manual J calculation procedures are also appropriate for some light commercial applications with additional data. All results computed by the RHVAC program can be easily verified by hand to be in accordance with ACCA Manual J.

PROGRAM INPUT
The RHVAC program is a true Windows program complete with toolbars and hyperlinked help. All input data is checked at the time of entry so that no improper data can be entered. Two types of data are requested: general project data and specific room data. The general project data includes the summer and winter design conditions, the outside air requirements, exterior shading and overhang data, the project name, the client name, and the designer name. The room input data includes specific information on the roof, walls, doors, and windows as well as general information on the room name, the number of occupants, and the number of appliances. Help is provided on all inputs. Data sheets are also provided for the easy organization of your information.

PROGRAM OUTPUT
The RHVAC program provides numerous presentation quality reports including a title page, general project data, total building and system load summaries, room summary data grouped by zone, detailed room load reports, sales proposal, and numerous color pie charts and bar graphs.
