Protective clothing and protective clothing temperature control method

The invention discloses a protective garment and a temperature control method thereof, and the protective garment comprises an obtaining device which obtains an inner-layer temperature value and an outer-layer temperature value of the protective garment; the calculation module is used for calculating a temperature interpolation coefficient of the protective clothing according to the acquired inner-layer temperature value and the external temperature value, and calculating a theoretical temperature value of the protective clothing according to the temperature interpolation coefficient; and the processor controls the air supply device to supply air to the inner layer through the air inlet to cool the inner layer when the inner layer temperature value is greater than the theoretical temperature value. The temperature interpolation coefficient of the protective clothing is calculated according to the inner-layer temperature value and the outer-layer temperature value of the protective clothing, the relevance betw
