Fujitsu Ductless Split Air Conditioning – Thermal Balance Calculation.
The overall heat balance anywhere, is calculated by summing the inputs and outputs of total thermal energy produced by heat transfer through walls, heat generated by artificial lighting and equipment, number of occupants, infiltration and solar radiation each of these factors are calculated individually and at the end is calculated individually and at the end you add up all the values obtained.
The gain of heat produced by the occupants of the space to be cooled is tabulated and depends on the activity that people develop within the space and the temperature of that environment. The gain can be considered in two parts. a) sensible heat gain (HS). b) latent heat gain (HL).
Split Ductless Air Conditioning – Thermal load generated by Lights.
All lighting systems, either incandescent or fluorescent basically convert electrical energy for operation in receiving heat, which shows in its entirety and is dissipated inside the space to be cooled, therefore, the following mathematical model to calculate the gain of heat generated by lighting and equipment.
Everywhere there is a continuous flow of outside air into through holes in doors, windows, which tends to alter the temperature of that place. As it is difficult to calculate the air flow area and more difficult to measure its speed, has been experimentally determined the amount of air entering different types of spaces in order to calculate the amount of heat for this item.
