What you'll learn
HVAC Cooling & Heating Load Calculation with Project & E-20
Requirements
Basic Knowledge of HVAC
Description
Learn cooling and heating load calculation in detail with Project, E-20 Chart & E-20 Excel
will begin with building survey to extract all parameters to prepare input file in detail to start load calculation
A building or room gains heat from many sources. Inside occupants, computers, copiers, machinery, and lighting all produce heat. Warm air from outside enters through open doors and windows, or as 'leakage' though the structure. However the biggest source of heat is solar radiation from the sun, beating down on the roof and walls, and pouring through the windows, heating internal surfaces.
The sum of all these heat sources is know as the heat gain (or heat load) of the building, and is expressed either in BTU (British Thermal Units) or Kw (Kilowatts).
For an air conditioner to cool a room or building its output must be greater than the heat gain. It is important before purchasing an air conditioner that a heat load calculation is performed to ensure it is big enough for the intended application.
