The present invention relates to a system for controlling the temperature and humidity of a livestock barn based on a heat quantity index. The present invention provides a control system which includes a thermometer and a hygrometer measuring the inner temperature and the inner humidity of the livestock barn and installs a heating device and a ventilating device controlling the temperature and a humidifying device and dehumidification device controlling the humidity in the livestock barn receives an applicable temperature and humidity range for a precise control, and the minimum valve (A) and the maximum value (B) of an optimal heat quantity index range (A-B) detects the temperature (T) and the humidity (H) of the livestock barn control the temperature (T) and the humidity (H) of the livestock barn to be within the applicable temperature and humidity range for the precise control increases the temperature and the humidity if the heat quantity index obtained by multiplying the temperature (T) (unit:°C) by the humidity (H) (unit:%) is lower than the minimum valve (A) and lowers the temperature and the humidity if the heat quantity index is higher than the maximum valve (B). Therefore, the present invention can maintain the optimal inner heat quantity index of the livestock barn with the control system, thereby improving productivity by minimizing diseases of livestock.COPYRIGHT KIPO 2014[Reference numerals] (AA) Detecting a temperature(T) and the humidity(H) and calculating a calorie index(Q) (BB) Temperature and humidity ranges for applying a precise control ?
