We have developed this "back-end" software using Microsoft Visual C++ and Microsoft Visual Basic (Versions 5 and 6). By taking advantage of the power of true object oriented programming (OOP), we can offer you our source code, allowing you to develop custom applications on virtually any platform (Unix, Macintosh, OS/2, and, of course, Windows). In addition, we have just released our Carmel Foundation Classes J+, which are Java classes which allow you to run calculations on any operating system platform, including Linux and Apple OS.

Duct Size 4.0 from Carmel Software is a comprehensive software package that sizes ductwork based upon numerous inputs. You may manually input duct sections, or utilize AutoCad to import single-line duct drawings. The software outputs a complete duct-size breakdown, a pressure schedule, a critical-path pressure drop, a material list output, a heat loss output, and many more types of outputs. In addition, Duct Size will output a double-line/3-D duct drawing to AutoCad that may be used for construction and design purposes.

Enterprise Estimate 5.0 from Carmel Software is a brand new (Summer 2002) HVAC estimating software package that allows you to estimate HVAC service jobs, requisition parts for the job, and keep track of billing. In addition, you can create customized databases of all types of information including customer labor rates, vendor rates, technician addresses, area labor costs, parts costs, and much more.

You can also purchase a Parts Database Subscription that includes the full parts database for Carrier, Lennox, and Trane. This allows you to easily insert the correct parts into your estimates and guarantee that the prices will be correct.

Life Cycle 3.0 from Carmel allows you to perform a number of engineering life cycle analyses. These include the following: Simple payback comparisons, without any discount factors; Simple cash flow analysis with discount factors; Complex life cycle analysis with multiple capital and non-capital investments. Capital investments refer to assets held by a firm that are used in some way in business operations. They can be depreciated for income tax purposes, and can be subject to insurance costs and property taxes. This program provides the capability of financing the project over a set period of years. Capital investments include the cost of purchasing the equipment or building or its components. By comparing two different life cycle scenarios, each with their own set of capital investments, you may determine which one is preferrable, based upon net present value comparisons.

Loadsoft 4.0 is a commercial and institutional HVAC load calculation program. It calculates peak heating and cooling loads for purposes of sizing air-conditioning and heating equipment. The calculations in this software program are based upon the 1993 ASHRAE Fundamentals heating and cooling load equations. In this new version, we have incorporated many of your suggestions, and have offered many improvements and enhancements over the previous versions of Loadsoft. The following is a list of the many enhancements to Loadsoft 4.0:

Pipe Size 2.0 from Carmel Software is a comprehensive software package that performs hot/cold water pipe sizing. This is useful for sizing both chiller and boiler pipe systems. The software allows the user to either manually input the data or import single-line drawings from both AutoCad DXF and Visio. All calculations were derived from the ASHRAE Fundamentals 1997, Chapter 33.

Psychrometric 4.5 The Psychrometric 4.5 software package provides the capability to work with standard psychrometric charts on the computer screen. A mouse can be used to plot points and lines. In addition, a spreadsheet can be brought up which lists up to 31 characteristics of each point plotted on the chart. The chart can be customized to exact needs, whether it be low temperature refrigeration, or normal HVAC cooling processes. This software package is intended for the mechanical engineer and engineering student who wants to better understand psychrometric processes. Psychrometric 4.5 runs under all versions of Microsoft Windows. The psychrometric chart software package utilizes ASHRAE Fundamental calculations to construct the graph, and determine the characteristics of all the points.

This product is geared toward the software developer who wishes to incorporate a psychrometric control within their application. This control is an "OCX" control, which means that you can drag it onto your Visual Basic, Delphi, or C++ application. This control displays a generic psychrometric chart, and it allows you to set its properties to customize it to your exact needs.

The Refrigeration 3.0 load calculation program is a software package that provides refrigeration cooling loads for refrigeration boxes per 24-hour period. It contains inputs for roof and wall dimensions, lighting, people, infiltration, equipment, product and container types, and safety factors. Outputs include a full load break-down by roof, wall, people, container loads, and more. In addition, other out-puts include psychrometric characteristics and a summary output. The software includes a full ASHRAE database of different food and container types and their load contributions (sensible and latent). Refrigeration 3.0 utilizes ASHRAE-based HVAC tables and formulas for calculating loads. Many of the formulas are derived from the ASHRAE 1994 Refrigeration Handbook, Chapter 26.

The Residential HVAC Load Calculation Program is a software package providing light commercial and residential heating and cooling loads based on numerous detailed inputs. This program is geared specifically toward the design/build contractor and residential design mechanical engineer. Residential is 100% compatible with all versions of Windows. The user-friendly interface provides a familiar look and feel found in all Windows-based programs. Residential calculates peak loads based upon the ASHRAE residential calculation methods. The outputs include a summary of all loads and cfms, a detailed breakdown of each and every load component, a psychrometric output summary, and a breakdown of the load profile for each wall and window orientation.

Toolbox 3.0 is a collection of 13+ simple mechanical engineering design routines. It is intended for all engineers who desire quick and easy engineering calculations.

The U-Value 4.0 software contains a full database of major wall, roof, window, and floor constructions with their respective weights, -Values, and thick-nesses. The data is based upon the ASHRAE publication: "Heat Transmission Coefficients for Walls, Roofs, and Floors," 1993, by Timothy James and William P. Gross. This package allows the user to edit values, create new U-Value databases, print information, and export it to the Loadsoft 4.0 HVAC load calculation software package.
