Windows BTU = South Window(s) BTU + North Window(s) BTU Obviously if you are in the Southern Hemisphere you would swap the conversion factors as the heat on North facing windows is then greatest.Īdd together all the BTUs for the windows.

South Window BTU = South Facing window Length (m) x Width (m) x 870 North Window BTU = North Facing windows Length (m) x Width (m) x 165 If there are no blinds on the windows multiply the result(s) by 1.5. If, however there are windows you need to take the size and orientation into account. Room Area BTU = Length (m) x Width (m) x 337 Window Size and Position If, as is quite common, your Server Room has no windows, you can ignore this part of the calculation. The heat load depends on a number of factors, by taking into account those that apply in your circumstances and adding them together a reasonably accurate measure of the total heat can be calculated*.įactors include: The floor area of the room The size and position of windows, and whether they have blinds or shades The number of room occupants (if any) The heat generated by equipment The heat generated by lighting Floor Area of Room The amount of cooling required depends on the area of the room. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). Early warning of problems and spare capacity in theĬooling system are both highly desirable.Ĭalculating Heat Load The amount of heat generated is known as the heat gain or heat load. Failure of the air conditioning can have serious consequences for the equipment itself and for your company. Providing sufficient cooling is essential to ensure reliable running of servers, routers, switches and other key equipment. Fire regulations often require that Server Rooms have levels of insulation far above that of a normal office. In practice it’s rather more complicated.

In principle it’s easy to calculate the size of air conditioning unit you need for your Server Room, just add together all the sources of heat and install an air conditioning unit that can remove that much.

"Indian Interface to EnergyPlus: HLCP Hourly Load Calculation Program HLCP (Hourly Load Calculation Programme) is a graphical user interface for design-day and hourly load calculations for Indian cities, meant to be used with the Energy Plus simulation engine. The convective component is converted to space cooling load instantaneously. The difference between the space heat gain and the space cooling load is due to the storage of a portion of radiant heat in the structure. Figure 3 shows the difference between the space heat gain and the space cooling load. Space cooling load is the rate at which heat is removed from the conditioned space to maintain a constant space air temperature. The portal is co-ordinated by Rajeev Kakkar more POSTED BYĬooling load calculation Space Heat Gain and Space Cooling Load Space heat gain is the rate at which heat enters a space, or heat generated within a space during a time interval.
