The incoming air cools down in the WT to room temperature the used air takes out their warmth The humidity increases if it enters into the room but it will be mixed with the existing air This has a stable humidity of only 60 65 Why Because the plaster at the wall and at the ceiling can store the surplus humid ity but slowly The saving process needs sufficient time which it gets from the con trolled airing In the case of uncontrolled airing plaster can not rapidly react it would be too much water Now there is the reserve in order to let evaporate the plas ter and it cools fantastically It feels agreeable also if the room temperature is 25 and more By controlled airing with the CVS the quantity of the incoming water will be strongly limited so that the lower quantity of water can be dry in the cooler nights For this reason you should use little air flow at the day in order to work in the night with a higher flow because the outside temperature is mostly lower as the room tempera tures For this reason you must consider the different airing demands in the winter and in the summer This kind of cooling costs no additional cent because the controlled airing should run everywhere at every time A cooling machine is not necessary energy devourer and climate killer but only the assumption A good insulated house leak proof and all air exchange will be made via the heat exchanger Function of the CVSrobusto The Comfort
