HEAT LOAD CALCULATION

When we calculate the heat load, we have to know the location of space (Country,City)
And then building information such as building type,material,orientation & authority standard (Which standard we have to follow? local or international ).
Main Heat Source are Internal Heat Gain , External Heat Gain and Heat Gain from OA (FA)
See following Heat Load Chart.


1-Internal Heat Gain
  • Heat Gain from Lighting 
  • Heat Gain from Human
  • Heat Gain from Electrical Equipments
2-External Heat Gain
  •  Heat Gain from Wall 
  •  Heat Gain from Window
  •  Heat Gain from Roof
  •  Heat Gain from Floor
  •  Heat Gain from Partition
3-Heat Gain from Outdoor Air /Fresh Air 
  •   Fresh Air Requirement for Comfort Air
  •   Fresh Air by infiltration
