It calculates the maximum dissipation in free air of electrical
cabinets containing electrical or electronic equipments.
Difference between the dissipated power and that to dispel naturally will be the thermical potentiality of the conditioner or the cooling system additional to install.
Heat dissipation coefficient
Width . . . W
Height . . . H
Depth . . . D
Maximum ambient temperature
Maximum internal temperature
Real power to dissipate
|Maximum dissipated power in free air||W|
|Equivalent thermical dissipated power||kcal|
|Not dissipable power||W|
|Cooling capacity necessary (equivalent)||frig|
|Cooling capacity necessary (equivalent)||Btu|
Thermical power to dissipate is the summary of all the dissipation of the components into the cabinet, for example :
