Refrigeration Technology Research Of Automobile Air Conditioning Special High Temperature Area

For a long time,the design and manufacture of automotive air conditioning refrigerationin special high-temperature region plagued by major automobile manufactures and themain parts manufactures.Air conditioning design departments of company technologycenter spent more time,effort and cost to study this subject.This article is the research ofthis topic,and put forward a set of solutions to the problem,look for automobile airconditioning practioners and major manufacturers have some significance in resolving thisissue.The article mainly is divided into four parts.The first part is an introduction and automotive air conditioning refrigeration principle.The second part is through a high temperature environment simulation test to reproducethe problem.The third part is the automotive air conditioning theoretical calculation,to various partsof the structure and parameters design provide a reference design.The fourth is related Parts bench experiment test certification,simulation under hightemperature environment of automobile air conditioning refrigeration experiment.Through to reproduce special high-temperature environment of the area,looking for theproblems,the average temperature of the car can not meet the standard demand,in additionthe vehicle air conditioning system liquid impact phenomenon exists. Then through theprofession benchmarks, theoretical calculation and considering the actual situation topropose the feasible solution. Finally using parts bench test and simulation of hightemperature environmental test are sure to improve. Through automotive simulation testunder the condition of high temperature environment, to determine the optimal designresults.
