Date Sep. 1, 1983.A sphere of house building technology and refers to the heat-insulating part of an outer wall in a building. Also other walls in the building may be suitable if there are temperature differences between spaces and a need for ventilation. The basic principle consists in the wall construction itself constituting a heat exchanger of counterflow type and transmitting both humidity and heat from the exhaust air (fresh air) to the fresh air (exhaust air). At the same time the same surface temperature is achieved as that of the ambient air. |
