The Weather Eye was a trade name for a Nash Motors-designed fresh-air system for automobile passenger compartment heating, cooling, and ventilating. The Nash "All-Weather Eye" was the first automobile air conditioning system for the mass market.〔(【引用サイトリンク】title=A Counterpersons Guide To Climate Controls )〕 The use of the Weather Eye name for automobile passenger heating and air conditioning systems continued in American Motors (AMC) vehicles. The design principles of the Nash Weather Eye system are now in use by nearly every motor vehicle. ==Conditioned Air System== In 1938, Nash Motors developed the first automobile heater warmed by hot engine cooling water, and using fresh air. This "Conditioned Air System" is characterized by a cowl-mounted outside air receiver that passes fresh air through a heater core utilizing hot engine coolant for a heat source. The Nash system also pioneered the use of slight pressurization within the passenger compartment to eliminate the infiltration of cold outside air during winter use. This was a fan-boosted filtered ventilation and heating for the passengers, not the modern meaning of an "air conditioning" system.〔 Nash was also the first automobile to make use of a disposable filter in the air-intake to clean incoming air.〔 The Nash system was a major advancement compared to what was used up to that time: heating by recirculating the air inside the car.〔 A concurrent development, the Evanair-Conditioner was offered by Hupmobile on their 1938 and 1939 model cars. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Weather Eye」の詳細全文を読む スポンサード リンク
