The present invention relates to a sterilization and constant temperature air supply system for livestock using both geothermal and UV-C LEDs having a wavelength of 200nm to 280nm, and more particularly, to maintain the temperature supplied to the livestock using geothermal temperature, which is the temperature of the ground. , In addition, it relates to an air supply system for livestock for both sterilization and constant temperature for supplying clean air by sterilizing pathogens and molds in the incoming air using UV-C ultraviolet rays. The present invention for achieving such a technical problem, in the sterilization and constant temperature combined livestock air supply system using UV LED ultraviolet rays and geothermal heat, an air inlet 100 for introducing air from outside the livestock to the inside of the livestock； An air outlet unit 200 for supplying sterilized and constant temperature air to the inside of the house； A heat exchange unit 300 for controlling the temperature of the air introduced from the air inlet 100 using geothermal heat； A sterilization unit 400 for sterilizing the air introduced from the air inlet 100 through a UV-C LED having a wavelength of 200 nm to 280 nm； A control unit 500 for controlling the power of the UV-C LED having a wavelength of 200 nm to 280 nm； It characterized in that it comprises a. In addition, preferably, the air outlet 200 is characterized in that it further includes an exhaust fan device to control the amount of outflow air. In addition, preferably, the control unit 500 further comprises a recirculation unit 600 for recirculating the air inside the house to the air inlet 100 in order to properly maintain the temperature of the outlet air inside the house. To do. `본 발명은 지열과 200nm~280nm 파장을 가지는 UV-C LED를 이용한 살균 및 항온 겸용 축사용 공기 공급시스템에 관한 것으로서, 더욱 상세하게는 지중의 온도인 지열을 이용하여 축사로 공급되는 온도를 유지하고, 또, UV-C 자외선을 이용하여 유입되는 공기중의 병원균, 곰팡이 등을 살균하여 청정한 공기를 공급하는 살균 및 항온 겸용 축사용 공기 공급시스템에 관한 것이다.이러한 기술적 과제를 달성하기 위한 본 발명은, UV LED 자외선
