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. A control knob controlled ventilation in summer and heating in winter.
Automotive heaters for the passenger compartment of closed cars at that time were simple space heaters of a recirculation type. Most were mounted under front seat with coils for the engine coolant, some were gasoline-fired, and others using engine manifold exhaust heat. The systems had no provision for fresh outside air and most lacked a fan to move the air. Ventilation for the car's cabin was provided by opening a window or even the windshield.
The innovative "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.
Concurrently developed, the Evanair-Conditioner was made by Evans Products Company as an aftermarket accessory. The air was drawn through special hood louvers through a heating coil system mounted on the engine side of the firewall. The Evanair system was available from the factory or installed by a dealership on 1938 and 1939 Hupmobile cars.
