The present invention discloses a four-season heating and purified air supply apparatus for purifying the room and maintaining the appropriate temperature. The outside air drawn into a housing through an outside air guiding pipe is sterilized and purified by passing through an air filter and a sterilizing lamp discharging UV rays generating ozone and sterilizing the air. The ozone-containing air, which is sterilized and purified, passes through a blower and is drawn into an outside air crossing chamber. A merging induction pipe including a furnace flue is drawn in the outside air crossing chamber and is installed to have the outlet face the front side of the housing. The flame outlet of a burner is surrounded by the inlet of the furnace flue to discharge the heated air to the outlet of the furnace flue. When the blower is operated, ozone-containing air, which is sterilized and purified, is supplied to a room after passing through an air guide path between the merging induction path and the furnace flue. When the blower and burner are operated at the same time, the temperature of the ozone-containing air is raised by the combusted air flows from the furnace flue and the ozone-containing air is mixed to be supplied to the room. A large amount of the sterilized and purified ozone-containing air can be supplied to the room and heated by using a burner if necessary. Accordingly, the present invention can provide the fresh, sterilized, and purified air into the room constantly and adjust the temperature during winter while minimizing the door opening for ventilation, thereby significantly reducing the heating costs. Accordingly, the present invention can increase the combustion efficiency of the burner on the outside of a stable and enhance the immune system of livestock.COPYRIGHT KIPO 2015실내 공기를 정화 및 적정 온도 유지를 위한 사계절 난방 및 정화 공기 공급장치가 개시된다. 외기유도관을 통해 하우징 내부로 흡입되는 외부 공기는 에어필퍼와, 살균 및 오존발생 자외선을 방출하는 살균램프부를 거치면서 살균 정화된다. 살균 정화된 오존함유 공기는 송풍기를 지나, 외기경유챔버 안으로 투입된다. 외기경유챔버 안에는 화로
