Abstract
The measuring of the title unit is described. The unit is a Kantherm ES 4000, a heat recovery unit with two heat accumulating parts and a switching valve. The aim of the measurements was to determine the temperature efficiency and the moisture transport from the outlet air to the supply air. It concerns heat recovery from ventilation air. First a measuring method is developed, based on data from available literature, expertise within the TNO-institute IMET, bench-scale experiments and a few practical experiments. Attention is paid to measuring points, measuring equipment and data processing. Next a practical measurement was carried out within the project Merwedekade in Dordrecht, Netherlands. The Merwede-project is a U-shaped 4 to 6 storeyed building for the elderly people, a service centre, offices, and an atrium. The most important conclusions with regard to the performance testing of a heat recovery system in a Kantherm heat recovery unit are that 1. practical measurements can be carried out satisfactory; 2. the measured efficiency appears to be constant; 3. the temperature efficiency RT lies between 72 and 77%. RT is the quotient of the temperature rise of the supply air and the maximal feasible temperature change, related to the outlet air
