That is the electronic control system activating the pump for spray circulation, and lowering the air intake of the condenser, raising the condensing temperature of the cooling system, and therefore raising the evaporation and exhaustion speed of the condensed water.
  • the air intake of the condenser under strong draining mode is about 40% to 80% of the air intake of the normal operation, and the condensing temperature is 5 to 20° C. higher than normal operation.
  • the condenser and evaporator use a fan and motor, and a exhaust valve by the electronic control system is set up at the air intake channel of the condenser and the air intake channel of the evaporator, the indoor air after being extracted into the movable air conditioner is divided into two directions, one enters evaporator wind channel and later discharged indoor for cooling after exchanging heat with the evaporator, another enters condenser wind channel and later discharged outdoor after exchanging heat with the condenser.
  • the electronic control system controls the exhaust valve to decrease the air intake of the condenser and increase the air intake of the evaporator, and thereby controls the discharge speed of the condensed water.
  • the movable air conditioner employs a dual shaft motor to drive two independent condenser fan and evaporator fan
  • the wind channel systems of the condenser and evaporator are independent as well
  • the electronic control system controls the exhaust valve to decrease the air intake of the condenser and increase the air intake of the evaporator, and thereby controls the discharge speed of the condensed water.
