TEST METHOD OF HEAT RECOVERY UNITS IN SINGLE HOUSES

摘要

The study was to test five units used in single house mechanical ventilation systems with heatrecovery. Tests were made according to CEN project prepared by CEN TC 156/WG2/AH7including air tightness, pressure-airflows curves and temperature ratios. A fill test on frostand condensation was also realised on one unit to determine the influence of these parameterson pefiormances. Test results, influence of wet or dry conditions and main conclusions forusing these results in dimensioning, will be given.
