For large environments the recommended provisions
are those given in Fig . 1 and Fig . 2.
Positioning air blowers
With this provision it is aimed to obtain a circular air
flow in the environment and to neutralize the loss of
heat at the origin .
For modest size environments are advisable
provisions such as those of Fig . 3 and Fig . 4 .
