Abstract: A blower device including: a motor holder having an opening; a motor housed within the motor holder; a blower fan coupled to the motor; an electronic circuit adapted to control the motor. The motor holder includes an air inlet and an air channel configured to supply the electronic circuit and the motor with an airflow from the air inlet. The air channel includes a first deflector wall and a first liquid trap wall arranged in series between the air inlet and the electronic circuit. The first deflector wall and the first liquid trap wall extend in opposite directions and form a meandering path for the airflow.

Abstract: A method and HVAC system having a heat exchanger and a device for adjusting parameters of an HVAC system via an algorithm, in an incremental or linear fashion, is provided. Various aspects provide a method for altering and/or controlling auxiliary evaporator temperature in an automotive HVAC unit and an HVAC system having an HVAC unit with a blower and a temperature sensing device capable of detecting temperatures that drop below a desired minimum operating temperature and sending a corresponding signal, ultimately preventing evaporator freezing.
