Aircraft cooling systems are great.
Many years ago, airplanes did not have hardly any air conditioner units or heaters.
One day, an Heating, Ventilation and A/C worker named Jerry decided he was done being too frigid or hot on airplanes so he began building an cooling system and a boiler that would work well on an airplane. He started by studying cooling systems and boilers inside other things like cars. He would start the a/c device in the vehicle and then open the hood and watch how the cooling system worked. He proceeded to do this with the car boiler and heater. After his observations, he went to his Heating, Ventilation and A/C shop and began party heating and cooling component and media air cleaners, hot water boilers, window cooling systems, and so several other Heating, Ventilation and A/C units. Once Jerry felt he had enough boiler and a/c parts, he got to work on his Heating, Ventilation and A/C masterpiece… Jerry had a fantastic neighbor that owned a small plane and he let Jerry test his cooling system and boiler prototypes on his plane. After a full year of heating and cooling research and taking apart lots of gas boilers and mini split cooling systems, Jerry finally made an cooling system that would keep any airplane cool and a boiler that would hot up the inside of an airplane. Once the a/c and france were on the market, every airplane company began buying the Heating, Ventilation and A/C units up and Jerry had a strenuous time making enough cooling systems and boilers for these companies. One day, the heating and cooling industry provided to factory produce the airplane z/c units and boilers for him.
