Cooling system configuration
Especially in warmer climates, Nautel recommends an air conditioned cooling system with ducted
exhaust and free-air return. A split system air conditioner can be cost effective, provided the distance
between the evaporator and condensor can be kept to a minimum. This configuration also minimizes
dust and sand buildup within the equipment. An example of this type of system is shown in
, which shows a combined NX400, 800 kW transmitter system with each transmitter having
a dedicated split system air conditioner, with a third split system air conditioner used to cool the heat
load in the room from various sources (e.g., power transformers, combiner losses, solar, other
equipment, etc.).
shows a diagram of a split system air conditioner system, as well as examples
of indoor an outdoor unit components.
