Abstract
An air conditioning unit includes a passage having a heat exchanger; a blower for blowing air through the passage; a blower motor driving the blower in response to a drive signal; an energy recovery ventilator (ERV), the blower drawing outside air from the ERV; and a controller for adjusting the drive signal in a ventilation mode to reduce power used by the blower motor.
Claims6
An air conditioning unit comprising:
- a passage having a heat exchanger;
- a blower for blowing air through the passage;
- a blower motor driving the blower in response to a drive signal;
- an energy recovery ventilator (ERV), the blower drawing outside air from the ERV;
- and
- a controller configured to control the drive signal;
- wherein in heating or cooling mode, the blower motor uses a first power;
- wherein in a ventilation mode, the controller adjusts the drive signal to reduce power used by the blower motor to a non-zero power less than the first power;
- wherein the blower motor is a pulse width modulated (PWM) motor;
- the drive signal being a PWM signal to drive the blower motor.
