The general procedure for calculating cooling load for each load component (lights, people, walls, roofs, windows, appliances, etc.) with RTS (ASHRAE) is as follows: Calculate 24 h profile of component heat gains for design day (for conduction, first account for conduction time delay by applying conduction time series). Split heat gains into radiant and convective parts. Apply appropriate. Constructions using the latest ASHRAE Radiant Time Series (RTS) cooling load calculation method. The work involves calculation of cooling load theoretically by introducing the design data for Iraq, and verifies the results experimentally by field measurements.

About This Item
Full Description
[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.Citation: ASHRAE Radiant Time Series (RTS) Method Load Calculation Spreadsheets, 2017

Cooling Load Calculation Rts Program 2
Commercial HVAC 'ASHRAE' Loads
Chvac quickly and accurately calculates the maximum heating and cooling loads for commercial buildings. The cooling loads can be calculated with either the CLTD method or the new RTS (Radiant Time Series) method. The program allows an unlimited number of zones which can be grouped into as many as 100 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 2000 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 zone loads, air handler summary loads, outside air loads, total building loads, building envelope analysis, tonnage requirements, CFM air quantities, chilled water flow rates (if applicable), and complete psychrometric data with entering and leaving coil conditions. Other outstanding features include ASHRAE Standard 62 analysis, automatic building rotation, 360 degree wall orientations, tilted glass, exterior shading, internal operating load profiles, variable indoor design temperatures, people diversity, pretreated outside air, seasonal infiltration and ventilation rates, reheat loads, duct gains and losses, and return air plenums. Chvac project data files can also be used by Elite Software's EZDOE energy analysis program.
