Arrangement til anvendelse i forbindelse med en luftkonditioneringsenhed

The present invention relates to an arrangement in connection with an air conditioning unit, comprising means (15, 16, 19, 20) for conveying exhaust and supply air through the air conditioning unit, a heat recovery unit having at least two stages (1, 2) and means for introducing additional heat or cooling power into the supply air. To enhance heat transfer, the means for introducing additional heat or cooling power into the supply air comprise at least one heating device or cooling device (3) disposed between the stages (1, 2) of the heat recovery unit in the exhaust air flow or separate air flow, adapted to change the temperature of the exhaust air and thereby to influence the temperature of the supply air indirectly through the heat recovery unit.
