Building and construction industry professionals require specialized software to provide thermal comfort and good air quality for the occupants of a building. There is an increased focus of late on energy saving and environment-friendly HVAC systems. Building services software allows for higher energy HVAC system installations with a focus on energy and cost-efficiency. The software provides simulations that help engineers and contractors to see how the final installation will work and perform. The software programs improve the efficiency of professionals in the industry by eliminating manual calculation and human errors. They provide long-term value and make the entire process highly streamlined and output-focused.
Here, we will discuss some of the popular air conditioning and other building services software used in the building, construction and HVAC industries.
This feature-packed and intuitive air conditioning, load estimation and psychometrics computer program calculates the design, heating and cooling loads and associated psychometrics for an air conditioning plant. Psychometrics can predict the changes in the environment when the amount of heat and moisture changes. Psychometric analysis helps determine the volume flow rates of air that needs to be pushed into the ducting system.
Camel air conditioning heat load calculation estimation program provides the summation of heat transfer elements into gains or losses in a building space. Each heat transfer element is a load component that could be external, internal or system load. A psychometric chart provides a graphical representation of the relationship of the state or condition of the air at any particular time.
The psychometric chart displays various properties of the air such as:
• Dry-bulb temperature
• Wet-bulb temperature
• Dew point temperature, and
• Relative humidity
If any of these two properties are known, the other two can be determined with the help of a psychometric chart. The chat’s usage goes beyond these representations as it provides an amazing amount of information about the air including its moisture content, specific volume, energy content and a lot more. This information can be used in diagnosing environment problems such as whether or not moisture condensation will occur at a given surface.
Drop panels, balconies, light wells and shading schemes can be modeled with the help of Camel. You can view the shadow patterns of the shading devices as they traverse any selected wall or roof with varying time.
Technical details of Camel air conditioning load estimating and psychometrics software
• Hourly cooling load estimation can be performed taking into account the thermal storage on a design day for each month of the year.
• Fresh air quantities can be entered at room or zone level as i/s/person. The program calculates the fresh air quantity with the help of Compartment Formula from ASI668-1991 for various rooms and zones.
• Specific monthly 3 pm design dry and wet bulb temperatures are available for more than 600 locations in Australia and other regions of the world.
• The entire building can be easily rotated in the simulation with actual elevations.
• Recalculated U values and surface densities for a wide range of standard wall and roof constructions are available.
Camel air conditioning heat load calculation program provides a comprehensive set of results including summary tables of loads and air quantities. The results can be displayed graphically and a psychometric chart is provided for each AHU. Camel is designed to work in both Northern and Southern Hemispheres.
This air conditioning load estimation software can be used for estimating air conditioning loads in small buildings. This cut-down version of the widely-used Camel air conditioning heat load calculation software produces a load chart for up to 10 zones in a commercial or residential building. The program’s detailed load chart produces each individual component of the load. Drop down selection menus make data entry easy.
Graphics are provided on the Windows and External Walls & Roofs Screens for checking the input data. The air quantity for each zone is determined based on the leaving coil temperature or by-pass factor entered by the user.
Temperatures are provided for a number of preset result selections. Koala program results include a cooling and heating load chart for each zone. Summary results and tables can be individually selected with the help of checkboxes to build a print file.
Koala can be used to analyze buildings in the Northern and Southern Hemispheres. Users can enter their own design conditions for locations not provided in the program.
Dolphin is another useful HVAC software for duct and fitting pressure loss calculations. It calculates pressure loss on a series of ducts and fittings for determining the required fan pressure for a duct network. The program performs an hourly cooling load analysis taking into account thermal storage on a design day. Summary results include total pressure loss of the supply and return ducts and fittings. The maximum velocity in the supply and return duct is also displayed.
Donkey is an air conditioning ductwork design software that determines the size of a duct network. It carries out a complete acoustical analysis and determines quantities for costing purposes. Supply and return networks can be entered in duct coils and silencers can be entered.
These are just some of the useful building services software by ACADS-BSG. The company has designed many more air conditioning heat load calculations and building software for the benefit of HVAC professionals who need accurate and advanced engineering calculations and simulations for their various building services needs. Comprehensive, in-screen help is available at each screen to assist the user. For more information, ACADS-BSG customer care can be contacted by email or phone.
