(Source: Aalborg Universitet) 20.02.2017 kl. 13.00 - 17.00 English description In cold climates, mechanical ventilation systems with heat recovery, e.g. air-to-air exchangers, are often used to reduce energy demand for heating. This, however, creates a risk of ice accretion on the fins of the heat exchanger as warm and humid exhausted air cools down which may lead to the deterioration of equipment performance.There are two approaches to controlling ice formation on heat exchangers: active and passive methods....
