Abstract: An air-conditioning clothes system used in car, which has an air-conditioning device having a cooling unit and with air-conditioning clothes to be worn by the driver and passengers. The air-conditioning clothes include, in its interior, a pipe duct having air openings. The air-conditioning device is connected through connection pipe ducts to the air-conditioning pipe duct of the clothes so that cold air is driven by a convection fan located at the cooling end of the cooling unit of the air-conditioning device. When it is hot, cool air is delivered into the air-conditioning pipe duct of the air-conditioning clothes and is blown from the air openings to the ambient environment. When it is cold, warm air produced by a heating end converted by the cooling unit and driven by the convection fan to be dispersed into the ambient environment through the air openings provided on the air-conditioning pipe duct of the clothes.
