This paper will examine the various design and performance criteria for optimized internal heat exchanger performance as applied to R134a and HFO-1234yf systems. Factors that will be considered includ....
As global automotive manufacturers prepare for the introduction of HFO-1234yf as the low GWP refrigerant solution in Europe, concern over compressor durability and material compatibility still remain.....
The European f-Gas Directive phases out HFC-134a from Mobile Air Conditioning systems (MACs) in new vehicles by 2017. In the US pending California and USEPA regulations have incentives to phase out HF....
Experimental investigations have been carried out to determine the AC system performance with HFO-1234yf as the working fluid. System level bench tests have been conducted with an AC system from a 200....
Virtual simulation of passenger compartment climatic conditions is becoming increasingly important as a complement to the wind tunnel and field testing to achieve improved thermal comfort while reduci....
Following the previous reports, ventilation characteristics in automobile was investigated by using a half-scale car model which was created by the Society of Automotive Engineers of Japan (JSAE). In ....
Under increasing pressure to address global warming concerns, the use of HFC-134a refrigerant in mobile air conditioning in European Union (EU) countries will be phased out starting January 1, 2011. H....
The present study describes the design optimization of blower scroll of an automotive AC system to improve the overall performance. An automobile AC unit mainly consists of blower unit and heating/coo....
In recent times, CFD (Computational Fluid Dynamics) simulation tools have been deployed by automotive OEMs for investigating Climate Control applications. In automotive vehicles, one such critical app....
The purpose of this article is to study current refrigerant emission levels in China with reasonable accuracy of the first year vehicles. This is an initial survey on refrigerant irregular emissions b....
