Carmel Software develops and markets Heating , Ventilation and Air-Conditioning software (HVAC Software) for commercial heating and cooling load calculations, Residential heating and cooling loads, Duct sizing, Psychometrics, Refrigeration, and HVAC estimating. Carmel has customer through the world including many from the Fortune 500 and the U.S. Government.

Design-Build 6.0 program from Carmel Software refers to a suite of software programs that perform HVAC design-build analysis including commercial and residential load calculations, duct sizing, cost estimating, and proposal generation

Duct Size 6.0 is an engineering software program that performs HVAC (Heating, Ventilation,and Air Conditioning) duct design based upon the ASHRAE 2005 Fundamentals. This program allows the user to input a wide variety of information about a duct system, and it displays numerous reports such as duct dimension and airflow breakdown report, a material list, a heat loss breakdown report, friction loss breakdown report, sound-power breakdown report and many others.

Estimate 6.0 provides you the means to estimate new construction HVAC jobs. It includes a comprehensive database with many types of HVAC equipment, parts, metals, duct material, liner and insulation, labor, and much more. All of this information can easily be accessed from the estimate spreadsheet so you can create complete cost and labor estimates. After the estimate has been completed, you can export it to a custom Microsoft Word or Excel proposal template to be presented to the customer.

Loadsoft 6.0 by Carmel Software is a commercial and industrial HVAC (Heating, Ventilation, and Air Conditioning) load calculation software package whose calculations are based upon the ASHRAE 2005 Fundamentals radiant time series (RTS) method. These are the latest and most update-to-date calculations provided by ASHRAE.

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.

Residential 5.0 is a residential and light commercial HVAC load calculation software based upon the ASHRAE 2001 Fundamentals residential algorithms (Chapter 28). This program is geared specifically toward the design/build mechanical contractor, design mechanical engineer, and building maintenance supervisor or engineer.

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.
