Indoor temperature prediction method and system

The invention relates to an indoor temperature prediction method and system.The indoor temperature prediction method comprises the steps that the indoor heat dissipating capacity, the exhaust temperature, the air inlet temperature and the outdoor temperature of a target space are obtained; according to the indoor heat dissipating capacity, the exhaust temperature and the air inlet temperature, the target air volume provided for the target space by a heating and ventilation system is obtained; and according to the outdoor temperature, the indoor heat dissipating capacity and the target air volume, an indoor temperature predicted value of the target space is obtained. By adopting the method, the prediction accuracy of the indoor temperature of the target space can be improved, so that the potential high-temperature steep-edge effect in the space adopting direct-current ventilation cooling can be identified more accurately, an operator can be reminded to take corresponding measures in time, and the safety is imp
