The internal fan draws return air from the shelter into the Silencio, to:
• Circulate the internal air, when the return temperature is not too high (Recycle)
• Draw out the return air and push it through the air condition system to cool the air
(active cooling)
• Blend the return air with fresh air and push this new cooled air back to the shelter
(recycle/free cooling)
• Push warm air from the shelter to the outside in order to remove excess heat (free
cooling)
• Circulate the internal air and push it through the heating system to warm up the
supply air back to the shelter (heat)
• The internal fan is active in all modes, and runs continuously in various speeds.
The external fans draw ambient air into the Silencio to:
• Cool the condenser (active cooling), or
• Provide ambient air to the shelter (free cooling or emergency cooling)
• The external fans are active in active cooling, free cooling and emergency cooling
The compressor circulates the refrigerant in the cooling system.
The heater keeps the internal temperature at an adequate level at low ambient
temperatures, and is often also used to heat up the shelter in start up conditions.
The control board allows the user to change settings and to obtain information.
The control board controls the following active parts:
• Heater element
