Abstract
An air conditioning and ventilation system for a motorcar has an outdoor air passage for introducing fresh outdoor air into the passenger room and another passage for guiding room air to the atmosphere. The two passages intersect at a point where a heat exchanger is provided for exchanging both of the actual heat and the latent heat of the airs flowing through the two passages. Air heating and cooling units are provided in the outdoor air passage downstream of the heat exchanger. The outdoor air flows first through the heat exchanger in heat exchanging relationship with the room air flowing therethrough outwardly and thus is heated or cooled by the room air, whereby the thermal load on the air heating and cooling units is greatly reduced.
