HVAC Load Calculation Using HAP 6.2 Software

Explore how HAP 6.2, Carrier early analysis program, performs hvac load calculations and energy analysis to determine cooling and heating loads, system capacity, and energy cost aligned with ASHRAE standards.

Learn to add weather data in HAP 6.2 by selecting a weather station from the ASHRAE database, configuring design parameters for Hyderabad, and setting cooling and heating design conditions.

Create ground, first, second, and roof levels for the floor plans, name each level, set occupiable or roof type, and align floors with a shared reference marker, then lock positions.

Learn to draw and trace external, interior, glass, and partition walls in Revit, assign wall types, name spaces, and verify ceiling and level heights for accurate 3d models.

Define wall layers in HAP 6.2 by configuring an exterior wall with absorptivity settings, detailing bricks, air gap, plywood, metal stud, and gypsum board, then compute R and U values.

Define roof layers in hap 6.2 by creating a default roof, selecting a single 12-inch masonry concrete layer, and removing extras to yield the 1.66 R and 0.55 U values.

Define floor layers by selecting slab on grade and setting absorptivity (light 45% or medium 67.5%), then specify masonry concrete 12 inch and U value 0.553 with ASHRAE 0.92 resistance.

Add door data in HAP 6.2 by specifying door name, type (glass or opaque with light), and adjusting glass U value (0.83) and SHGC for accurate performance.

Implement thermal zoning by dividing the building into zones served by one thermostat and one airflow control, assign spaces to zones, and designate unconditioned areas across floors.

Select exterior and interior wall, roof, ceiling, and floor layers from the project library in HAP 6.2, and create new assemblies by entering layer details when needed.

Select and configure an air system in HAP 6.2 for an educational building, choosing AHU with chilled water, a VAV system, space model, and notes per ASHRAE standards.

Size hvac systems with the HAP 6.2 sizing data: compute AHU airflow, coil capacity, and system size using computer generated calculations; learn when to use system versus zone sizing.

Define a default plant and educational building alternative, then activate the view design report for system inputs; resolve wall assemblies, review coil loads, and note zone sizing for duct design.
