The purpose of the AIR MIX KIT function is that of exploiting, whenever this is possible, the temperature of the outside air to take advantage of a mixed air to be able to work without using a chiller, i.e. with no energy consumption.
WINTER OPERATION: When the outside air temperature drops below the set-point value for a given time, the chiller works only in free-cooling mode. When the temperature of outside air furtherly decreases, the microprocessor activates, the mix of the outside air with the inside one.
MID-SEASON OPERATION: It is obtained by combining the free-cooling system with the mechanical cooling one. The operation of the unit in free-cooling mode is activated when the temperature of outside air is 5°C lower than the user’s temperature.
SUMMER OPERATION: When the temperature of outside air is higher than the user’s one, the cooling capacity is granted by the work of the compressors; the free-cooling system stays active to optimize the performances of the chiller.
