Air conditioning system

A method of operating an air conditioning system, the method comprising:

• determining, by a controller, whether a power supply of a battery is sufficient;
• determining, by the controller, whether a starting signal is generated to determine whether an engine of a vehicle is operated;
• in response to determining that the starting signal is not generated, setting, by the controller, an operation time for discharging internal air to an exterior of the vehicle using a second fan;
• operating, by the controller, the motor to perform a normal rotation;
• supplying, by the controller, electricity to an electromagnet to prevent a first fan from being rotated by a shaft;
• setting, by the controller, a position of an intake door that connects the inside of the vehicle to the exterior to allow the internal air to be discharged to the exterior;
• setting, by the controller, a torque of the motor to apply a predetermined voltage/current to the motor and to discharge contaminated air or smell in the vehicle to the exterior of the vehicle;
• determining, by the controller, whether the operation time of the motor passes;
• and
• in response to determining that the operation time of the motor has passed, operating, by the controller, a switch to set the motor be rotated in a normal direction.

A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:

• program instructions that determine whether a power supply of a battery is sufficient;
• program instructions that determine whether a starting signal is generated to determine whether an engine of a vehicle is operated;
• program instructions that set an operation time for discharging internal air to an exterior of the vehicle using a second fan, in response to determining that the starting signal is not generated;
• program instructions that operate the motor to perform a normal rotation;
• program instructions that supply electricity to an electromagnet to prevent a first fan from being rotated by a shaft;
• program instructions that set a position of an intake door that connects the inside of the vehicle to the exterior to allow the internal air to be discharged to the exterior;
• program instructions that set a torque of the motor to apply a predetermined voltage/current to the motor and to discharge contaminated air or smell in the vehicle to the exterior of the vehicle;
• program instructions that determine whether the operation time of the motor passes;
• and
• program instructions that operate a switch to set the motor be rotated in a normal direction, in response to determining that the operation time of the motor has passed.
