Heat Load Calculation | HVAC Design | HVAC System
The Heat load calculation is very important part in HVAC Design. Whether its an important for an energy upgrade system in new home or building. Its getting accurate heating and cooling load calculation is vitally important role for HVAC system design. HVAC design is more impact on home’s construction costs, comfort, air quality and energy efficiency.

Solar <strong>Heat</strong> Gain:<br />
Solar heat gain for a specific room greatly depends on its direction or<br />
alignment - consider that the sun’s position in the sky changes throughout<br />
the day. In the morning, east-facing walls and windows are exposed to<br />
direct sunshine. South-facing surfaces are exposed to direct sunshine<br />
during noon, and west-facing surfaces during the afternoon. Walls facing<br />
north experience the lowest solar heat gain.<br />
Depending on how solar heat gain occurs, its effects can be felt<br />
immediately or over a period of time. For example, solar heat entering via<br />
glass windows (radiation) has an immediate effect. On the other hand,<br />
when heat gain occurs by conduction across walls, the walls themselves<br />
store heat and it continues to be released indoors at night.
