摘　　要：通过数学公式推导并结合经验数据给出了焓差室回风口处干湿球温度取样器内不同风速下额定制冷量偏差的计算方法。The indoor air enthalpy method is the most common method to measure the cooling capacity,in which the ambient humidity has a great influence on the measurement results of the cooling capacity,and the wind speed in the wet and dry bulb temperature sampler is one of the influencing factors.In this paper,the calculation method of the rated cooling capacity deviation under different wind speeds in the wet and dry bulb temperature sampler at the air return outlet is given by means of mathematical formula derivation and empirical data.
