本文指明用换气次数法计算泵房的排风量,有时不能满足排除泵房内余热的需要,并给出了根据水泵自身发热量及泵房室温要求计算排风量的计算式。
In this paper, it is indicated that calculating the exhaust air volume of pump house by the frequency of ventilation can not meet the need of eliminating residual heat in the pump room at times. The calculation formula of exhaust air volume based on the self-heating of the pump and the room temperature of the pump room is given.
