The Information Technology block of classrooms required a solution which could both cool the classrooms and have a positive benefit on the rest of the building.
Three top discharge coolers have been wall mounted adjacent and below the first storey classrooms.
Air is ducted upwards and then split into two branches which deliver the air to two separate classrooms.
The air flow and cooling can be controlled manually or automatically using a combined thermostat/humidistat which sets the fan speed and cooling mode according to the temperature set point.
It can be seen from the above performance chart that in Surrey the air temperature from an evaporative cooler rarely exceeds 200C making it an ideal solution for this type of application.
