  • the indoor unit and the outdoor unit are connected via piping for refrigerant circulation. Since the outdoor unit is installed outdoors, the main body of the outdoor unit and the surrounding area of the outdoor unit become hot during high temperatures such as in summer.
  • the outdoor unit is equipped with a heat exchanger that exchanges heat between the outside air and the refrigerant.
  • the heat exchanger mounted on the outdoor unit functions as a condenser when the air conditioner is performing cooling operation. At high temperatures, the heat exchange efficiency of the heat exchanger decreases, the cooling capacity of the air conditioner decreases, the load on the air conditioner increases, and power consumption increases. Therefore, there is a need to improve the heat exchange efficiency by cooling the outdoor unit.
  • One technique to improve the energy-saving performance of air conditioners is to sprinkle water on the heat exchanger installed in the outdoor unit.

  • a water spray nozzle is installed at a location away from the heat exchanger, such as the type 1 nozzle and type 2 nozzle described in Patent Document 1, to reduce the heat exchanger's energy consumption. Sprinkling water over a wide area is effective. However, if the droplets are atomized or the nozzle is moved away from the condenser, the sprayed droplets become more susceptible to external disturbances such as crosswinds, resulting in the problem of not being able to spray water on the intended areas of the heat exchanger due to external disturbances. occurs.
