While it may be impossible to create a calculator that is both simple and all encompassing. With many simple HVAC calculators already available, I choose to emphasize accuracy and customization over simplicity. In order to display all the necessary data, these calculators are best viewed on a laptop or desktop computer; sorry, but they are not mobile-friendly without zooming in and panning around. If you should find that a calculator has an error (and have a moment), would you mind helping me fix it by sending me a description of the issue, or just a screenshot? I will never use your email address for any purpose other than a “thank you”! Ever wondered if a systems Line Set contributed to the demise of its compressor? For residential and light commercial split systems up to 7.5 tons, this tool calculates the minimum and maximum acceptable pre-fabricated Line Set tubing sizes that will accommodate correct velocities without excessive pressure drop.
Roof-top Curb Adapters that retro fit any new HVAC Unit to. Duct Calculator. Home >My Tools >Duct Calculator. Air Duct Calculator Flexible Duct. Duct Calculator, Free Download. Duct Calculator is a powerful tool that provides access to duct. It is a precise and powerful tool designed for HVAC&R.
Calculations assure proper oil return without the use of vapor line oil traps which reduce capacity and efficiency. Download Free Software Ewa Chodakowska Skalpel Rapidshare Library. Credit and thanks goes to Bruce Porter P.E. He provided me the Engineered Factors critical to performing the line size calculations. This calculator provides notes for when 'Long Line' and/or 'Maximum Vertical Separation' accessories are recommended by manufactures (at least those who publish line sizing design procedures).
A calculating web form for recording and calculating the Stepwise air balancing process. Enter the outlet description (optional) and the design airflow, click 'Calculate' to display the 10% range. Enter the measured value of each outlet and it will tell you the percentage you are over or under, if within 10% it displays 'OK'. Balancing a 'Rule of Thumb' designed duct system is difficult if not impossible. Balancing is easy when the branch ducts are the size determined by the Manuals J and D procedures. Then only small changes in damper position are required. Typically less than 25%.
