1. For many years the prevailing opinion of automotive engineers held that from an engineering standpoint the refrigerated air conditioning application of an automobile was impractical due to the variable natures under which the system must operate It was seen that the demand for air conditioning included a rapid cool down of an extremely hot car interior this temperature sometimes soaring to as high as 1657F The same amount of refrigeration capacity would be adeguate for a building interior space of perhaps 20 or more times the interior space of the average automobile It was felt that this type air conditioning would require special equipment which was at the time not available and to make it available would result in too much cost after taking into account the anticipated low sales volume Even though there were automobile air conditioners before World War Il it was not until after the war that automobile air conditioning gained a good foothold This foothold was in the southwestern part of the United States where several small manufacturers began assembling equipment for use in designing automobile air conditioning which equipment was being manufactured for residential air conditioning and commercial refrigeration The first attempts were crude but the results were effective and it began to look as if a new business was born Quickly the manufacturers of the components that make up a refrigeration apparatus began designing spe2.
