Vaporiser with a plurality of coolant circuits which are adapted in accordance with the distribution of the air flowing through the vaporiser

摘要

Device for air-conditioning large vehicle compartments, in particular the passenger compartments of buses, consisting of a housing for attachment to the vehicle roof, which housing has an air inlet in the centre for sucking the circulation air out of the vehicle and has two air outlet openings through which the cooled air enters the interior of the vehicle again via two channels which are attached under the roof of the vehicle and in which the vaporiser which is mounted in a droplet tray of an air-conditioning system and a plurality of blowers arranged in parallel are arranged one behind the other, according to the invention the configuration of the tubular length of the individual circuits of the coolant of the vaporiser being adapted, upstream of the vaporiser, to the air distribution brought about by the droplet tray, in such a way that the overheating temperature at the end of the coolant circuits of different lengths is the same, and the coolant-conducting pipe between the injection valve and venturi distributor being bent with predetermined arrangement of the injection pipes in the venturi distributor and at the vaporiser in such a way that each circuit is fed that amount of fluid coolant which is required for the same degree of overheating of the individual circuit outlets. <IMAGE>
