A heat and cold air feeding mechanism is provided to supply the pure air since the internal air is circulated according to using the outside air, and to increase the efficiency of heating and cooling. A warm and cold air feeding mechanism comprises a cold and hot water supply part(10) including a cold and hot water supply conduit(15) which the cold and hot water to one side supply of a cold and hot water tank(11), a heat exchanger(20) including a warm and cool air radiation plate radiating the warm and cold air, a warm and cold air switching section(30) including a warm and cold air supply opening(36) which supplies the warm and cold air to one side of the exchange body(21), a cold and warm breeze feeding port(40) which supplies the cool and warm breeze. The cold and hot water supply part comprises a hot water boiler(12) which is installed at the lower part of cold and warm water cistern in which the water is provided, and which is heated by a hot water heating unit(13). The heat exchanger comprises a pressurized section(35) in which the area is reduced in order to pressurize the cold and warm air passing through the switching section. |
