Calculation of air exchange in battery rooms

1. The purpose of the calculation is to determine the supply air flow to the battery rooms.

Set: - space area - F = 15.7 m2,

- room height H = 4 m,

- number of rooms m = 2 pcs,

- surface area of battery cans electrolyte

in one room Fa = 2.6 m2,

- highest charging current Iz = 143 A,

- number of storage battery elements z = 108 pcs.,

- heat generation in room Q = 0.9 kW,

- maximum ambient air temperature tl = 31.10 С,

- maximum permissible temperature in rooms

storage batteries tdop = 350С.
