Abstract
A method for controlling a heating, ventilation, and air conditioning (HVAC) system, may include: allowing, by a controller, only the indoor air to be directed into a housing when the HVAC system operates in a cooling mode and an engine is stopped by an Idle Stop and Go (ISG) system; allowing, by the controller, the indoor air directed into the housing to bypass a heater core; and maintaining, by the controller, a flow rate of the air directed into the housing at a minimum flow rate.
Claims12
A method for controlling a heating, ventilation, and air conditioning (HVAC) system including a housing having an outdoor air inlet through which outdoor air is allowed to draw in and an indoor air inlet through which indoor air of a vehicle is allowed to draw in, an inlet door for opening or closing the outdoor air inlet and the indoor air inlet, an evaporator mounted in the housing, a heater-side passage and a bypass passage formed in parallel in the housing on the downstream of the evaporator, a heater core mounted within the heater-side passage, a temperature door pivotally mounted between the heater-side passage and the bypass passage and configured for opening or closing the heater-side passage and the bypass passage, and an air blower blowing air into the housing, the method comprising:
- allowing, by a controller, only the indoor air to be directed into the housing by controlling the inlet door, when the HVAC system operates in a cooling mode and an engine is stopped by an Idle Stop and Go (ISG) system;
- allowing, by the controller, the indoor air directed into the housing to bypass the heater core, by controlling the temperature door;
- and
- maintaining, by the controller, a flow rate of the air directed into the housing at a minimum flow rate, by controlling the air blower.
