The paper presents the mathematical model, based on the narrow-channel approximation, for calculating the processes of heat and moisture transfer in membrane heat exchangers and taking into account possible condensation on heat exchange surfaces. The possibility of humidifying the supply air with moisture from the exhaust air in the cold period is considered. It is shown that the membrane co-current heat exchangers can operate without freezing up to the outdoor temperature equal to -20 °C.
