Cooling Load Spreadsheet
HVAC COOLING LOAD CALCULATIONS AND PRINCIPLES 1.0 OBJECTIVE Cooling load calculations may be used to accomplish one or more of the following objectives: a) Provide information for equipment selection, system sizing and system design. B) Provide data for evaluating the optimum possibilities for load reduction. Apply RTS to Radiant Gains HOURLY COOLING LOAD. With ASHRAE Load Calculation Principles Book Software that comes. For Design Cooling Load Calculations. Perform online ACCA Approved load calculations in minutes. Supports block load or room-by-room. 100% cloud based, can be accessed anywhere, anytime, from any device. Some simplified cooling load calculation methods, such as transfer function method (TF) 20 and radiant time series method (RTS) 21, have also been developed for air system. These algorithms. Uses ASHRAE commercial load calculation methods using Right-Draw or the. Calculations), and supports both CLTD and RTS load calculation methods. This program uses the 24-hour by 12 month ASHRAE Handbook of Fundamentals methods to compute light, medium or heavy heating and cooling loads for an.
Cooling Load Spreadsheet
I'm an ME, but not in HVAC. I'd love to get a pointer to a spreadsheet or some demo software that would help us put our minds at ease that we won't be cooking next summer.
The rough details for those of you who love to solve problems:
Location: Atlanta, GA
Roof: 48x58ft 2' gypsum with membrane
SW Wall: 48X14ft Brick over block, interior finished
SW Windows: ~40X8ft 1/4' glass with 50% darkening film
NW Wall: 58X14ft block shared with conditioned space, interior finished
NE Wall: 48X14ft Brick over block, interior finished
SE Wall: 48X14ft Brick over block, interior finished
SE Windows: 25x8ft 1/4' glass with 50% darkening film 80% shaded.
Floor: 48x58ft slab on grade.
Occupants: about 20 people and computers
We want to make sure enough cooling gets to the SW windows. They've got 3 tons going over in their new plan, and another 5 ton unit for the rest of the space. Previously we had 2.5 tons near the windows, and it felt inadequate.
I'm not trying to get someone to do work for free, but I did want to provide all the details. A pointer to a good web reference/spreadsheet/demo would be great.
Cooling Load Calculation Rts Programming
[Note: this version uses I-P units only]The 2017 Radiant Time Series (RTS) Method Load Calculation Spreadsheets (in I-P units) are intended as an educational tool both for the student and for the experienced engineer wishing to explore the RTS method. They have been updated for use in the examples found in Chapter 18, Nonresidential Cooling and Heating Load Calculations, of the 2017 ASHRAE Handbook--Fundamentals.These spreadsheets allow the user to perform RTS cooling load calculations for lights, people, equipment, walls/roofs, and fenestration components. Calculate component loads for design day weather profiles for any month. Updated weather data for stations in the United States, Canada, and elsewhere around the world from the 2017 Fundamentals volume are included for ease of user selection. Solar equations in the spreadsheets are applicable to the southern hemisphere, as well.Calculate cooling and heating loads for individual rooms or block load zones. Use the 12-month cooling calculations to determine the month and time of peak cooling load for each room or block load zone. Room/zone worksheets can be copied and modified within the spreadsheet to analyze as many rooms or zones as desired; the number of rooms/zones is limited only by the available computer memory.System Requirements: WinZip and Microsoft Excel. File size is 25 MB, so we recommend a broadband internet connection when attempting to download. Zip file includes 2 files totaling 99 MB.
