Chvac has been an industry leader in commercial eite calculation software since Try Elite Software’s flagship program today and see why so many professional engineers are choosing Chvac.

Chvac quickly and accurately calculates the maximum heating and cooling loads for commercial buildings. The program allows an unlimited number of rooms which can be grouped into as many as 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 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 room loads, air handler summary loads, outside air loads, total building loads, building envelope analysis, tonnage requirements, CFM air quantities, chilled water flow rates if applicableand complete psychrometric data with entering and leaving coil conditions.

Other outstanding features include ASHRAE Standard 62 analysis, automatic building rotation, degree wall orientations, tilted glass, exterior shading, internal operating load profiles, eltie indoor design temperatures, people diversity, pretreated outside air, seasonal infiltration and ventilation rates, reheat loads, duct gains and losses, and return air plenums.

Keep in mind that a room is a single space, and that rooms can be grouped into air handling systems which in turn make up the building. Rooms can optionally be grouped under vav boxes as well zones.

This allows Chvac to compute diversified peak loads at four levels in one run of the program: The maximum number of air handling systems allowed for any version is the number of rooms allowed orwhichever is the lesser. Each Chvac version is exactly the fhvac with the exception of the room capacity and price.

However, there is a generous upgrade policy. If at any time you decide to obtain a version of Chvac with greater capacity than the original one you obtained, all that is required is to pay the difference in price between the two versions. Chvac contains many, many advanced features. Here chvc just a few of its capabilities. The RTS method is especially accurate because it calculates the delayed effect of radiant chvxc 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 room that peaks in the afternoon.

The CLTD method, on fhvac other hand, uses exact table values from the Handbook where possible, which means that you can verify the results by hand. 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.

Chvac is very easy to use and includes a specific “dropdown” help window for virtually every input, including a list of choices where appropriate. The program performs extensive checks on the data you enter and alerts you to chcac problems that it finds, eliite as a wall having too much window area, or a leaving coil temperature for an air cbvac outside of the expected range.

Five types of data are requested: The general project data includes the project and client name, designer, building opening and closing hours, internal operating load schedules, and any desired safety factors.

The outdoor design data includes the summer and winter outdoor design conditions automatically looked up for you if a city reference is given and the desired ventilation and infiltration rates. The building material data includes the definition of master building material types for roofs, walls, partitions, glass sections, and exterior shading. A user defined material library is available for saving the data on common material types.

The air handler data includes the fan and terminal type, the desired heating and elife supply air temperatures and data for duct heat gains and losses. The room data includes the room name, floor length and width, number of people, equipment watts, lighting watts, external shading data, and specific roof, wall, partition, floor and glass data.

Chvac elitd several different types of reports which can be selectively previewed on screen or printed. Virtually all calculated data can be exported to a comma delimited text file that you can then import into your favorite spreadsheet program such as Excel.

The Chvac load calc program calculates a great deal of the data needed to define a system in the HVAC Solution schematic diagramming program. Traditionally, this data has simply been transferred using a manual entry process. Chvac not only calculates peak heating and cooling loads, it also aids in selecting HVAC equipment and analyzing building operating costs.

In the future, we plan to also provide a link to the Energy Plus program. Export to Energy Audit when you want to analyze residential and light commercial projects, essentially any application which uses unitary HVAC equipment.

Chfac to eQUEST when you want to analyze large commercial projects that require precise modeling of variable loads, equipment, operating schedules, and control schemes.

We give you extensive control over the import process, including the ability to select which spaces, walls and windows to include in the import see screenshot below. If you are familiar with the data that CAD programs typically write to gbXML files, you know that material definitions are usually incomplete for purposes of load calculation, since they do not usually include data such as wall U-values or roof ASHRAE numbers.

So on the import dialog we let you select the default definitions for each kind of master material in the project. First, you enter your project in Chvac and let it determine your peak loads. A functional demo of Drawing Board is built into this version of Chvqc.

Question for anyone who uses Elite Chvac. – HVAC/R engineering – Eng-Tips

The built-in demo version of Drawing Board allows you to draw and save floor plans of unlimited size, but HVAC calculations chva only be made for two rooms of the floor plan. Chvac version 7 users can update to version 8 for a substantial discount off the full cuvac price. See the Upgrade Pricing page for more information. Chvac version 8 can be installed on the same computer as version 7, and will not interfere with version 7 at all.

You can download a limited, functional demo of EnergyPro from here. Each applicable master data item now has an EnergyPro Code input, which you chvax use to map that master item chvsc an EnergyPro material. Click the button beside any EnergyPro Code input and you’ll see an EnergyPro Material dialog, which lets you select the mapped material from dropdown lists. There is built-in mapping if you leave an EnergyPro Code input blank, but the e,ite mapping is easy to do, and is of course more precise.

Multiple items of equipment cooling chvacc for each room. Elit dialog is filled with sensible and latent load information for various kinds of equipment listed in various tables in both the and ASHRAE Handbook of Fundamentals. Multiple items of lighting loads for each room. Click the button beside the Lighting input on the Room Data window and a new Lighting Elitf window opens.

This window lets you create as many individual lighting load items as you need for each room, each with its own characteristics, such as Space Fraction, Usage Factor, etc. Dlite the button beside the Description column and a new Typical Lighting Loads dialog opens, which lets you choose from several lists of lighting items that come from tables in the and ASHRAE Handbook of Fundamentals. Click the menu “Project Load Preview” to open this new window. It’s similar to the window with the same name in Rhvac, but this one has over 90 columns of data available.

You can choose which columns to make visible. There is a corresponding Print Preview report. The Load Preview Layout dialog lets you choose one set wlite visible columns for the Load Preview window itself, and another set of columns for the Print Preview version of it. Plenum-Room temperature difference automatic adjustment. When you enter a return air plenum you can now specify that you want the program to automatically adjust chvca entered temperature difference between the rooms and the plenum until it converges on a solution.

You can select the maximum number of iterations to perform for each plenum, as well as whether or not to round to the nearest whole number temperature.

You can enter project defaults for these settings on the Design tab of the General Project Data window, and you can override them for each plenum on the Plenum Data window. In each room you can now calculate the latent load due to indoor swimming pools. All you have to do is enter square footage of the water surface, enter the water temperature, select an activity factor, and select an airflow velocity.

The program will then calculate a latent load for the swimming pool. Sloped Ceiling Area Calculator dialog. This dialog lets you enter dimensions for a room’s sloped ceiling, and calculates the resulting area of the ceiling.

The area is copied to the roof’s Width input, and the number 1 is copied cchvac the Length input. On the Air Handler Data window you can now enter miscellaneous supply and return latent equipment cyvac.

Loads can be positive or negative, and can occur on either the supply or return side of the coil. New Features in Version 7 The following new features were added to version 7 that were not in version 6. The RTS method is found in the latest ASHRAE Handbook of Fundamentals elitd is very accurate because it calculates the delayed effect of radiant heat gains during each of the past 24 hours on the current cooling load.

You can easily switch back and forth between the two methods simply by entering equivalent master roof, wall and glass data on the Master Data window for both methods.
