/ 127 BOOST AIR CONDITIONING AVL ConsysBoost The ��oost air conditioning system AVL ConsysBoost conditions the ��oost air temperature to a pre-defi na��le value and keeps it within a tight tolerance range mainly for steady state applications, or at least those with constant demand values. The ��oost air from the tur��o charger is indirectly conditioned ��y controlling the cooling water �� ow on the secondary side of the heat e��changer. CONTROL PRINCIPLE The boost air temperature control is performed indirectly by controlling the cooling water �� ow through the heat e��changer. A circulation pump ensures an ade��uate �� ow of cooling water in the heat e��changer even for low-power applications. In addition, this pump improves control behavior by returning the heated cooling water to the heat e��changer inlet. For simulating the pressure drop of different engine intercoolers, a valve is installed ��etween the AVL ConsysBoost and the engine intake duct. APPLICATION The standard ConsysBoost 1200 or 3000 units are ��asically designed for stable temperature control during a steady state or dynamic engine operation. Alternative solutions, such as spray variants or intermediate circuits, are availa��le for simulating dynamic temperature profi les. BENEFITS AT GLANCE �� The precise adherence to a pre-defi ned ��oost air temperature signifi cantly improves the reproduci��ility of measurements on turbo-charged combustion engines and, therefore, increases the test��ed effi ciency • The ability to simulate different pressure losses for different vehicle intercoolers allows use on a wide range of engines • The compact and mobile unit can be moved to different testbeds, saving investment costs by eliminating the need for extra units • Space-saving installation close to the engine by separating the conditioning part from the heat exchanger The AVL ConsysBoost is installed in the test room, close to the engine for a fast response time and good control stability. To save space around the engine, the intercooler and stand can easily be removed from the conditioning unit and located separately, close to the engine.
