Abstract

The invention relates to an arrangement and method, (means) to evaporate water in an air to air heat-exchanger and collect and circulate surplus water from the evaporation in the air to air heat-exchanger along with precipitation of condensed water (dehumidifying of air). Separation of surplus liquid and contamination's from ventilated air is accomplished through preferably allow supply air and exhaust air in the heat-exchanger first have the streams pointed downwards towards a collecting sump and thereafter pointed upwards whereby kinetic energy and/or gravity in the surplus water and material is collected in the collecting sumps at the bottom of the heat-exchanger. After that draining, drying, heat sanitation take place after which pure water is added and the cooling air conditioner is restarted. When dust and microorganisms have been collected in sufficient amount in the collecting sump the water is changed to clean water. Sterilisation of the arrangement takes place through the use of pre-and/or additional supply of energy that is forced to pass and heat the inner channel system and parts of the arrangement whereby survival and growth environment for microorganisms as bacterium, virus, fungi's become unsuitable within the arrangement and that the air gets rid of aerosols. The method to rinse out the canal system of the heat-exchanger. In the upper part, at need, a sprinkler system is installed to pour water upon and to rinse out the canal system of the heat-exchanger.
