This software package comes on a CDROM that includes versions of Adobe Acrobat Reader and Microsoft WORD for displaying the documentation (manual is included on the CDROM). BMP images files for each page of the manual are also included. This is a full (not just a demo) MSDOS product (will run in an MSDOS window with Windows 95, 98, 2000, XP, Vista). RESIDENTIAL COOLING AND HEATING HVAC ANALYSIS RCF calculates the cooling and heating loads, supply air, energy requirements, and heating/cooling costs for houses, apartments, mobile homes, and light industrial applications. Versions of RCF have been in use for over ten years. The present product has been fine-tuned to the needs of HVAC contractors, developers, equipment manufacturers, engineers, utilities, and energy agencies. In particular, the reports are personalized and professionally laid out in presentation format. The reports may include comparisons between sets of equipment for demonstration purposes (e.g., high-end vs. low-end). Thereby operating cost savings and differences in installation expenses may be examined for trade-offs. RCF uses the entire expanded "Manual J" list of construction materials, including insulation up to R-33 (walls) and R-57 (roofs). You can also enter your own specific materials. It handles air or water-cooled A/C, gas/oil/electric/coal/wood heating, and heat pumps (with or without other heating). Weather data for design conditions is stored on disk for 900 locations in North America and elsewhere, and you may add your own. It will handle shading from roof overhangs; internal glass shading; skylights; jalousies; sliding glass doors; tinted, reflective, low emittance, double- and triple-pane glass; storm windows and doors; and cathedral ceilings. Global changes in construction materials (such as the type of glass, insulation, etc.) can be easily made for "what-if" comparisons. RCF uses the ASHRAE/ACCA bin method for energy calculation. This is the most detailed and accurate method available for residential use. Loads are calculated using the ASHRAE/ACCA "Manual J" method. The calculated display of loads closely follows the "J" format. In addition to the above, other calculations include: o Sensible and latent heat requirement for infiltration and ventilation air. o Advice as to whether ventilation or combustion air is required. o Duct heat gain and loss, with allowances for duct location and insulation. o Linear feet of baseboard heat required for each room. o CFM of air required for all systems. o Overall "U" values for composite wall and roof constructions. o Changes which occur when the floor plan is "flipped" (as in a housing development). o Runs multiple systems with multizones. o Accesses the ARI equipment database if you have the ARI data disk. o Overlaid windows, automatic recalculation for changed inputs, "hot-spot" escape, many other user-friendly features. Data entry is easy and fast. Wherever possible, RCH provides default values for inputs. You can accept these values by pressing the return key, or enter your own values. There are pop-up windows and a pop-up calculator. Also, there are 200 context-sensitive messages and help screens, as well as extensive input error checking. Data is saved to disk under job names, and can be recalled for alterations and new runs. The RCF package includes a 100 page manual (on disk) suitable for even the most inexperienced user. Also, a sample job is included on disk for practice. Requires a dot matrix (e.g., Epson, IBM, etc.) or laser printer using the standard LPT1 port (as recommended by Microsoft).
