Disclosed is an electromagnetically openable air conditioning system for livestock. An electronically retractable air conditioning system for livestock according to the present invention includes: an air conditioner installed on one side of a livestock house to send out air conditioned at a set temperature; a duct part which is installed long in the barn in a state of being in communication with the air conditioner, and in which a plurality of tuyeres spaced apart from each other in the longitudinal direction are formed through; an opening/closing operation unit provided with a blocking plate that operates to open and close the air outlet according to the operation of the shape memory body, which is deformed by heating and cooling by the application of control power, to adjust the amount of air-conditioned air; a sensor unit provided in the duct unit to measure temperature and contamination level at different points; and a control unit for controlling the operation of the air conditioner and the opening/closing operation unit based on the temperature and the pollution level measured by the sensor unit. According to the present invention, the temperature or pollution degree of the entire livestock house can be easily adjusted based on the temperature and pollution level for each point measured by a plurality of sensor units, and the local temperature control for the unbalanced points in the livestock house and the exhaust of harmful gases are quick It is possible to improve the efficiency of heat management in the livestock house and to promote the welfare and safety of livestock related to the breeding environment.
