alessandro volta
bullet::::- 1902 – willis carrier of angola, new york, invented the first indoor air conditioning. "he designed his spray driven air conditioning system which controlled both temperature and humidity using a nozzle originally designed to spray insecticide. he built his "apparatus for treating air" (u.s. pat. #808897) which was patented in 1906 and using chilled coils which not only controlled heat but could lower the humidity to as low as 55%. the device was even able to adjust the humidity level to the desired setting creating what would become the framework for the modern air conditioner. by adjusting the air movement and temperature level to the refrigeration coils he was able to determine the size and capacity of the unit to match the need of his customers. while carrier was not the first to design a system like this his was much more stable, successful and safer than other versions and took air conditioning out of the dark ages and into the realm of science."
1900s (decade)
in a thermodynamically closed system, any power dissipated into the system that is being maintained at a set temperature (which is a standard mode of operation for modern air conditioners) requires that the rate of energy removal by the air conditioner increase. this increase has the effect that, for each unit of energy input into the system (say to power a light bulb in the closed system), the air conditioner removes that energy. to do so, the air conditioner must increase its power consumption by the inverse of its "efficiency" (coefficient of performance) times the amount of power dissipated into the system. as an example, assume that inside the closed system a 100 w heating element is activated, and the air conditioner has a coefficient of performance of 200%. the air conditioner's power consumption will increase by 50 w to compensate for this, thus making the 100 w heating element cost a total of 150 w of power.
