Become a HVAC Professional - Part 2/3- Load Calculations HAP

Identify the difference between roof and ceiling by understanding sun exposure, where the roof is exposed to sun and the ceiling is not, a crucial concept before load calculations.

Learn about external and internal heat loads and how heat transfers through conduction, convection, and radiation, with examples like kitchens and partition walls.

Explore wall heat load calculations using the overall heat transfer coefficient U, outside minus inside temperature, and wall area, with HP software auto-calculating U and noting glass conduction and radiation.

Understand glass heat load by examining conduction and radiation through windows. Learn how the overall heat transfer coefficient (U) combines window area and temperature difference to estimate heat gains.

Open the hap load calculation software, click new to create a project, and set ventilation standards, units, and preferences before proceeding with load calculations.

Add window details in hap by creating and renaming window entities, duplicating them to form A, B, C, D, and setting a U value of 2.1 with shading coefficient 0.4.

Add general properties for the living room in the load calculation, defining space, ventilation requirements per 62.1, and enabling auto-populated values from the library.

Analyze heat transfer through partition walls between conditioned and unconditioned spaces and learn to input area and temperature values in HAP to generate the design report for load calculations.

Perform load calculations to determine the AC tonnage for the master bedroom by duplicating the living room layout, adjusting floor area, windows, and partition heat.

Learn to create a system for each space, name each system after its space, uncheck central heating for cooling calculations, and set thermostat and design reports for the next video.

Preview design reports to verify total tonnage and room loads for the four-bedroom system, review airflow, coil loads, and psychometric analyses, and export the report in English.

Save your project by clicking here, selecting a folder, and creating a folder to store your files. Archive your current project to send by email as a single file.

Archive the project by saving it to a chosen location and optionally send the archive via email; the next video covers reading a drive and opening an audio analysis program.

Learn how to retrieve a project your friend sent from the desktop and share it using the archive option without compressing files.
