popularization of air conditioning
But when it comes to air conditioning, it can be popularized, mainly through cinemas. Most Americans first came into contact with air conditioning in cinemas. In the 192s, cinemas used air conditioning technology and promised to provide cool air for the audience.
Air conditioning has become as attractive as the movie itself, and summer has replaced winter as the peak season for watching movies.

in the 196s and 197s, a rare dry weather occurred in the United States. In order to solve the problem of cold and heat sources of air conditioning in arid and water-deficient areas, the United States took the lead in developing an air-cooled Chiller, which replaced the cooling tower with air heat dissipation. Its English name is: Air Cool Chiller, or Chiller for short!
