The computer program CAMEL is one of the leading air conditioning load estimation programs available. It calculates the design heating and cooling loads and associated psychrometrics for air conditioning plant in buildings.
Carrier HVAC System Design Software for analysis of building loads and energy. Peak Load Calculations, HVAC System Sizing, Energy Modeling: Detailed. CAMEL computer program is an air conditioning load estimation program that calculates the design heating and cooling loads for air conditioning plants in buildings. This computer program models a wide range of systems like constant volume heating and cooling and constant volume face and bypass.
The calculations are based on the AIRAH/IHRACE Application Manual DA9 'Air Conditioning Systems, Load Estimation & Psychrometrics' which incorporates the cooling load estimation techniques and data developed by the Carrier International Corporation with considerable extensions and refinements to these methods and data, developed by ACADS-BSG.

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. Heat load calculations There are several different methods of calculating the heat load for a given area: Quick calculation for offices For offices with average insulation and lighting, 2/3 occupants and 3/4 personal computers and a photocopier, the following calculations will suffice: Heat load (BTU) = Length (ft.) x Width (ft.) x Height (ft.) x 4 Heat load (BTU) = Length (m) x Width (m) x Height (m) x 141 For every additional occupant add 500 BTU. If there are any additional significant sources of heat, for instance floor to ceiling south facing windows, or equipment that produces lots of heat, the above method will underestimate the heat load. In which case the following method should be used instead. A more accurate heat load calculation for any type of room or building The heat gain of a room or building depends on: The size of the area being cooled The size and position of windows, and whether they have shading The number of occupants Heat generated by equipment and machinery Heat generated by lighting By calculating the heat gain from each individual item and adding them together, an accurate heat load figure can be determined. Step One Calculate the area in square feet of the space to be cooled, and multiply by 31.25 Area BTU = length (ft.) x width (ft.) x 31.25 Step Two Calculate the heat gain through the windows. If the windows don’t have shading multiply the result by 1.4 North window BTU = Area of North facing windows (m.
