PURPOSE: An indoor heating and cooling system is provided to improve heating and cooling efficiency and to help users of the system to easily control the amount and temperature of air being discharged. CONSTITUTION: An indoor heating and cooling system includes a heating and cooling device (10), a duct unit (20), branch pipes (30), a controller (40), a user controller (50), and a main controller (60). The heating and cooling device generates warm or cool air by heat-exchanging outside air. The duct unit is connected to the heating and cooling device and provides the warm and cool air indoors. The multiple branch pipes are connected to the duct unit. The controller is installed in the branch pipes and controls the opening degree. The user controller is installed on the outer surface of the branch pipes and controls the controller. The main controller controls the heating and cooling device. |
