HVAC Software and Psychometrics Calculator for the most Efficient Installation and Functioning of Bu

HVAC software is at the cutting edge of technological innovation in the building services industry. HVAC software, such as psychrometrics calculators, is used by building services engineers to increase productivity and profits. This is made possible by HVAC software's automation features, which make HVAC system installation in buildings faster and more efficient. HVAC software, such as psychrometrics calculators, perform advanced engineering calculations that save project engineers a significant amount of time compared to doing it manually. Furthermore, the possibility of error is greater in manual calculations. HVAC software's 3D simulations enable the visualisation of any HVAC system in a building prior to its actual installation. Changes to the simulation can be made to find the one that is best suited for a building. Building engineers can thus increase the accuracy of their work while saving money and time.

The usability of HVAC software is increasing as cities become more densely populated, with high-rise buildings posing unique HVAC system installation challenges. Furthermore, public spaces with large open spaces, such as malls, have their own specific requirements for an efficient HVAC system. In this section, we will look at some popular HVAC software and the key technical details that make these programs so useful to building services engineers.

CAMEL for air conditioning load estimation and psychrometrics

The CAMEL psychrometrics calculator by the ACADS-BSG loading building services company calculates the design heat and cooling loads as well as the associated psychrometrics for air conditioning plants in buildings. CAMEL is a computer program that works in both the Northern and Southern Hemispheres and is currently used by over 250 organizations in Australia, New Zealand, and Southeast Asia. Overhangs are accommodated by the psychrometrics calculator, which includes drop panels and reveals on both windows and walls. It also lets you see the pattern of shading devices like drop panels, balconies, and light wells.

Technical details of CAMEL psychrometrics calculator

On a design day in each month of the year, the program runs an hourly cooling load analysis that takes thermal storage into account.

Specific monthly 3 pm design dry and wet bulb temperatures are available in CAMEL psychrometrics calculator for over 600 locations in Australia and for many offshore locations.

Precalculated U values and surface densities for a wide range of standard wall and roof constructions are available in the computer program.

Fresh air quantities can be entered at room or zone level as I/s/person with the plant fresh air quantity determined using Compartment formula from AS1668-1991 for multiple rooms/zones.

Walls orientations can be at any azimuth and the entire building can be readily rotated.

Summary tables by CAMEL psychrometrics calculator include loads and air quantities, load charts and tables of check figures that can be selected using a series of checkboxes.

The results can also be displayed graphically and a psychrometrics chart is provided for each AHU.

The results viewing and printing screen provides for selection of various tables, load charts and summaries in viewing and printing modes.

DONKEY for air conditioning duct design

The ACADS-BSG computer program DONKEY determines the size of a duct network, performs a complete acoustical analysis, and calculates quantities for costing purposes. The psychrometrics calculator can perform powerful and comprehensive calculations thanks to features such as automatic connection of run out ducts to terminals and automatic insertion of fittings. The data for the psychrometrics calculator's calculations is extracted from the drawing, and the calculations are performed using items from the Utilities Menu.

Technical specifications of DONKEY psychrometrics calculator

The ductwork system and its various components can be sized using one of three methods: static regain, constant pressure gradient, or balanced pressure drop.

Allow for duct leakage on the basis of an I/s per joint per kilopascal pressure drop.

The computer program DONKEY includes pressure loss data for a wide variety of fittings, and balancing dampers can be inserted manually or automatically.

The noise level algorithms in the computer program DONKEY are extremely detailed, with many of them being quite unique and representing the most recent methodology available.

The breakout NR level is calculated for each duct individually based on its location in the ceiling space above the standard room.

Comprehensive help is available in all DONKEY dialogue boxes and drop-down menus, describing the various commands and input time.

On the actual duct layout drawing, the overall results, including duct sizes, pressure drop terminal NR levels, damper out-of-balance pressure, and noise levels at selected frequencies, can all be displayed on screen.

DOLPHIN for sizing and pressure drop calculations of duct runs, HYENNA+ automatic fire sprinkler or hydrant piping analysis, PYTHON for design of water piping system for air conditioning, WOMBAT sound transmission in and around buildings, and many more are examples of ACADS-BSG building services software that building contractors and vendors may find useful.

Acads-Bsg is a leading building service design software firm. We aim to provide building services designers with the software to design and check services.
