Abstract
A system and method for measuring odor from an air conditioner of a vehicle which are able to accurately measure air conditioner odor that varies in each operation mode of the air conditioner. The system and method enable accurate measurement of air conditioner odor that varies in each of operating modes of air conditioner such as a blower-on step, an air conditioner-on step, and an air conditioner-off step, and enable accurate examination and measures for an air-conditioning system on the basis of the measured result.
Claims16
A system for measuring odor from an air conditioner of a vehicle, the system comprising:
- an odor measurer connected to an air-conditioning system and configured to measure air conditioner odor in each operation mode of the air conditioner;
- a controller configured to compare a maximum concentration of air conditioner odor in each of the operation modes of the air conditioner with a reference concentration based on measurement signals of the odor measurer, and to determine different examination items of the air conditioner for each of the operation modes of the air conditioner when the maximum concentration of air conditioner odor in each of the operation modes of the air conditioner is over the reference concentration;
- and
- a display configured to display examination items of the air conditioner determined by the controller.
A system for measuring odor from an air conditioner of a vehicle, the system comprising:
- an odor measurer comprising a pre-chamber, an air intake line connected between a first side of the pre-chamber and a duct, an air flow line having a first end connected with the air intake line and a second end connected to a second side of the pre-chamber, and disposed across an inside of the pre-chamber, a valve mounted on the air intake line and configured to be opened and closed in accordance with control signals from a controller, an odor sensor mounted in an odor sensor chamber and configured to measure air conditioner odor that is suctioned through the air intake line and the air flow line, a connecting pipe connected between an inlet of the odor sensor chamber and the air flow line, and a suction pump connected to an outlet pipe of the odor sensor chamber;
- and
- a controller configured to open the valve to enable odor concentration to be measured by the odor sensor for a predetermined time from an on or off time point of an air conditioner switch, to calculate maximum concentration from the measured odor concentration, and to determine an examination item of the air conditioner when the calculated maximum concentration is over reference concentration by comparing the maximum concentration with the reference concentration.
A method for measuring odor from an air conditioner of a vehicle, the method comprising:
- measuring air conditioner odor in each operation mode of the air conditioner by an odor measurer connected to a duct of an air-conditioning system;
- comparing a maximum concentration of the air conditioner odor in each of the operation modes of the air conditioner with a reference concentration based on measurement signals of the odor measurer by a controller;
- determining different examination items of the air conditioner for each of the operation modes of the air conditioner by the controller when the maximum concentration of air conditioner odor in each of the operation modes of the air conditioner is above the reference concentration;
- and
- displaying, on a display, determined examination items of the air conditioner by control of the controller.
