Weather Eye
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. The use of the Weather Eye name for automobile passenger heating and air conditioning systems continued in American Motors Corporation (AMC) vehicles.
The design principles of the Nash Weather Eye system are now in use by nearly every motor vehicle.
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.
This was the first car heater that used fresh air from the outside, and it was advertised as "No dust to soil or spoil your trip! Nash's automatic 'Weather Eye' gives you fresh air, free of dust…rain….insects…chilling drafts!" The Nash system was a significant advancement compared to what was used up to that time: heating by recirculating the air inside the car. Nash also promoted the system's safety feature in eliminating the dangers of carbon monoxide.
A concurrent development, the Evanair-Conditioner was made by Evans Products Company as an aftermarket accessory and also available by Hupmobile on their 1938 and 1939 model cars.
In 1939, Nash added a thermostat to its system, making it the first thermostatic automobile climate control system. The Weather Eye "was the first truly good heating and ventilating system." Additionally, defoggers (defrosters) were incorporated with the introduction of the 3900 series cars that year.
Nils Eric Wahlberg designed the Nash HVAC system, which continues to be the basis for modern automobiles. Nash included the first automatic temperature control for the air side of the heating system, with the thermostat sensing the temperatures of the incoming outside air, the heater's discharge, and the interior of the car; so that a change in any of these three air temperatures resulted in an automatic adjustment to maintain passenger comfort. Nash's Conditioned Air System heater was then marketed as the "Weather Eye", and consumer sales literature explained that the thermostat's "mechanical eye" watched the weather, hence the name.
In 1954, Nash-Kelvinator capitalized on its experience in refrigeration to introduce the automobile industry's first compact and affordable single-unit heating and air conditioning system optional for all Nash Ambassador, Statesman, and Rambler models. It was a true vapor-compression refrigeration system with a compact under the hood and cowl area installation. Combining heating, cooling, and ventilating, the new air conditioning system for the Nash cars was called the "All-Weather Eye".
