Vehicle and building integrated air conditioning system and control method thereof

A vehicle and building integrated air conditioning system which fluidically communicates internal spaces of a vehicle and a building with each other when the vehicle is docked to the building to integrally perform air conditioning, the vehicle and building integrated air conditioning system comprising:

• the vehicle which includes a vehicle control unit configured of controlling a vehicle air conditioning device in the vehicle;
• the building which includes a building control unit configured of controlling a building air conditioning device, is provided with a station to which the vehicle is configured to be docked, and fluidically communicates an interior of the building with the vehicle to perform the air conditioning when the vehicle is docked to the station;
• and
• an integrated control portion which is electrically connected to the vehicle control unit and the building control unit and configured to allow the vehicle control unit or the building control unit to integrally control the vehicle air conditioning device and the building air conditioning device,
• wherein the integrated control portion is configured to set target temperatures of the internal spaces of the building and the vehicle, to control so that the air conditioning is executed in a dual mode in which the vehicle air conditioning device and the building air conditioning device are operated when differences between the target temperatures and current temperatures are equal to or greater than predetermined values by checking the current temperatures, and to control so that the air conditioning is executed in a single mode in which one of the vehicle air conditioning device and the building air conditioning device is operated if the differences therebetween are equal to or less than the predetermined values.
