  • the space left between the two ends of the outdoor heat exchanger and the casing as the outdoor side air passage can reduce the wind resistance on the outdoor side, increase the air volume on the outdoor side, thereby increasing the heat transfer coefficient of the outdoor heat exchanger, and finally making the entire air conditioner The energy efficiency ratio of the device is further improved.
  • the outdoor portion is provided with two outdoor heat exchangers installed side by side, and the outdoor fan is placed between the two outdoor heat exchangers.
  • the space for the outdoor fan is placed between the two outdoor heat exchangers.
  • the outdoor side air duct As the outdoor side air duct, the wind resistance on the outdoor side can also be reduced, and the air volume on the outdoor side can be increased, thereby increasing the heat transfer coefficient of the outdoor heat exchanger, and finally making the whole The energy efficiency ratio of the air conditioner is further improved.
  • the outdoor fan is an axial fan. The axial flow fan consumes less energy, so this can reduce the energy consumption of the entire air conditioner.
  • the outdoor heat exchanger includes a coil and a fin sleeved on the coil, the coil is bent by a copper internally threaded tube, and the surface of the fin is coated with a hydrophilic film.
  • the indoor heat exchanger includes a coil and a fin sleeved on the coil, the coil is bent by a copper internally threaded tube, and the surface of the fin is coated with a hydrophilic film. This can increase the heat transfer coefficient of the heat exchanger, thereby increasing the energy efficiency ratio of the entire air conditioner.
