Abstract
A vehicular air conditioning system includes: an intake part including an intake door configured to open an outdoor air inlet to introduce an outdoor air in an outdoor air mode, open an indoor air inlet to introduce an indoor air in an indoor air mode, and control an opening degree of the outdoor air inlet or the indoor air inlet, and a blower configured to suck the indoor air or the outdoor air through the indoor air inlet or the outdoor air inlet and blow the indoor air or the outdoor air into a vehicle interior; and a control part configured to control a rotational speed of the blower according to an air flow rate level of the air conditioning system.
Claims10
A vehicular air conditioning system, comprising:
- an intake part including an intake door configured to open an outdoor air inlet to introduce an outdoor air in an outdoor air mode, open an indoor air inlet to introduce an indoor air in an indoor air mode, and control an opening degree of the outdoor air inlet or the indoor air inlet, and a blower configured to suck the indoor air or the outdoor air through the indoor air inlet or the outdoor air inlet and blow the indoor air or the outdoor air into a vehicle interior;
- and
- a control part configured to control a rotational speed of the blower according to an air flow rate level of the air conditioning system,
- wherein the rotational speed level of the blower is automatically adjusted according to the temperature conditions inside and outside the vehicle and the user-set temperature or the rotational speed level of the blower is adjusted according to the rotational speed level selected by the user when a user manually selects the rotational speed level from off to seventh level, and
- wherein the control part is configured to control the blower to rotate at different rotational speeds according to the outdoor air mode or indoor air mode at the same air flow rate level of the air conditioning system, and
- wherein the control part is configured to execute control to make the rotational speed of the blower higher in the outdoor air mode by a preset value than in the indoor air mode at the same flow rate level.
