Abstract
An outside air conditioner unit includes a heat exchanger for conducting refrigerant, and a fan for circulating outside air across the heat exchanger. The fan is disposed coaxially within a hollow cylinder which can be adjusted axially relative to the fan by a motor to vary the intensity of the air flow. The fan motor is connected to a controller which actuates the motor in response to a difference between outside air temperature and a reference temperature to reduce the air flow intensity when the heat exchanger is in an overload condition.
Claims7
An air conditioner, comprising:
- a housing;
- a heat exchanger in the housing for circulating a refrigerant;
- a fan in the housing for circulating outside air across the heat exchanger;
- a temperature sensor for sensing a temperature of the outdoor air;
- a controller connected to the temperature sensor for determining a difference between the sensed outdoor air temperature and a reference temperature to determine in response to that difference, whether the heat exchanger is in an overload condition;
- and
- a flow-regulating mechanism connected to the controller for increasing an intensity of air flow produced by the fan when an overload condition is determined, the flow-regulating mechanism comprising a hollow cylinder in which the fan is coaxially disposed, the fan being movable axially relative to the fan to vary the intensity of the air flow.
