Study On Model Of Parallel Flow Condenser In Bus Air Conditioning

With the development of automotive industry and the increasing of material civilization, people require more for amenity,reliability and security of auto mobile, so automotive air conditioning has been widely used. As the key heat exchanger equipment, the structure size and heat exchang performance of condenser have important impact on the layout,function characteristic and economy of bus air conditioning. High efficiency,lightweight and small-sized of condenser and the matching design of bus air conditioning system is one of the research priorities of bus air conditioning.In this paper, for 12-meter bus air conditioning system of Yangzhou Jiexin Auto Air-conditioner CO., LTD, use the Matlab software to establish the components of bus air conditioning system numerical calculation model, focus on simulation studying on parallel flow condenser and tube-fin condense. Using Simulink tools in Matlab to optimized simulat the model of the bus air conditioning, Access the main performance parameters of changes of bus air conditioning in used the parallel flow condenser and the tube-fin condenser, provide the basis for matching design of bus air conditioning system. And the bus air conditioning system performance experiment is done on the roof-mounted bus air conditioning performance experiment system, the experimental results verify the model of rationality and reliability.The result shows that the parallel flow condenser has better performance compare with the traditional tube-fin condenser, it is a new type heat exchanger that can increase the energy efficiency,realization the lightweight and small-sized,reduce the consumption of metallic materials and substantial increase the comprehensive benefits, also verified the numerical analysis tools has an important project value.
