Commercial HVAC 'ASHRAE' Loads

Cooling load and the methodology of calculation, an user can start running the program and perform the cooling load calculation for a model house. The selected model house is taken from an example in the ASHRAE Handbook 8. Load Calculation Program For the present program, the load calculation is based on the CLTD/SCL/CLF method. Mar 27, 2017 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.

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.

I have been using this program for load calculations, including accurate infiltration determination, and for all types of energy modelling. This program is awesome for suppoting LEED projects and comparing various choices of system types and control as well as thermal storage and load shifting. See full list on carrier.com. ASHRAE RTS/CLTD Load Calculations: Right-CommLoad ™ is based on the internationally accepted ASHRAE heat loss/gain standards (ASHRAE 62 standard ventilation calculations), and supports both CLTD and RTS load calculation methods.
