Title (EN) A HEAT EXCHANGER IN PLANTS FOR VENTILATING ROOMS OR BUILDINGS
(FR) ECHANGEUR DE CHALEUR POUR LA VENTILATION DE PIECES OU DE BATIMENTS
Abstract: front page image
(EN)A heat exchanger in plants for ventilating dwelling rooms, for example. The heat exchanger (10) is of the recuperative type with two duct systems (11, 12) separated by a plurality of heat-transferring partition walls (16). Supply air and exhaust air are controlled by a valve means (33) to alternate, so that the two air streams are periodically shunted between the two duct systems depending, inter alia, on the outside air temperature and the inside air temperature and humidity. By means of shunting there is avoided, inter alia, condensation and possible frost formation in the heat exchanger simultaneously as the efficiency of the heat exchanger is improved.
(FR)Echangeur de chaleur pour la ventilation de pieces d"habitation, par exemple. L"echangeur de chaleur (10) est du type a recuperation avec deux systemes de conduites (11, 12) separes par une pluralite de parois de division de transfert de chaleur (16). L"air d"alimentation et l"air de refoulement sont commandes par une soupape (33) qui assure leur alternance, de sorte que les deux courants d"air soient periodiquement devies entre les deux systemes de conduite en fonction de la temperature de l"air a l"exterieur et de la temperature de l"air a l"interieur et de l"humidite. Au moyen de la deviation ou bifurcation, on evite la condensation et une eventuelle formation de givre dans l"echangeur de chaleur, augmentant simultanement le rendement de l"echangeur de chaleur.
