Overview-:
Chvac quickly and accurately calculates the maximum heating and cooling loads for commercial buildings. The cooling loads can be calculated with either the CLTD method or the new RTS (Radiant Time Series) method. The program allows an unlimited number of zones which can be grouped into as many as 100 air handling systems. Chvac automatically looks up all cooling load and correction factors necessary for computing loads. In addition, it can look up outdoor design weather data for over 2000 cities located around the world. There is also provision for editing the weather data as well as adding data for other cities. Comprehensive reports list the general project data, detailed zone loads, air handler summary loads, outside air loads, total building loads, building envelope analysis, tonnage requirements, CFM air quantities, chilled water flow rates (if applicable), and complete psychrometric data with entering and leaving coil conditions.
Other outstanding features include ASHRAE Standard 62 analysis, automatic building rotation, 360 degree wall orientations, tilted glass, exterior shading, internal operating load profiles, variable indoor design temperatures, people diversity, pretreated outside air, seasonal infiltration and ventilation rates, reheat loads, duct gains and losses, and return air plenums.

Calculation Method:
Chvac performs cooling calculations using either the CLTD method or the new RTS (Radiant Time Series) method. The
RTS method is described in the latest edition of the ASHRAE Handbook of Fundamentals, while the CLTD method is from
earlier editions of the Handbook. The RTS method is especially accurate because it calculates the delayed effect of
radiant heat gains during each of the past 24 hours in determining the current cooling load. That means, for
example, that the program gives proper consideration to the effect of an external shading device that shades a
window in the morning in a zone that peaks in the afternoon. The CLTD method, on the other hand, uses exact table
values from the Handbook where possible, which means that you can verify the results by hand. You can actually
switch back and forth between RTS and CLTD for any project. All you have to do to switch between the two methods is
to enter equivalent Master Data definitions for roofs, walls and glass and then change the Cooling Calculation
Method input to the other method.
