[暖通供热论文] 摘要： 屋顶式空调机冷却方式为风冷直接冷却。风速、分液器对其性能均有影响，同时集气管的形状、尺寸对它也有一定的作用。通过一系列的实验，可以看出集气管对蒸发器换热的影响，同时也间接反映了分液不均和风速不均。 关键字： 集气管 分液器 风速 蒸发器

Abstract: Cooling method of the rooftop air-conditioner is air cooling directly. Both air velocity and liquid-distributor have some effects on the performance. At the same time shape and size of the discharge pipe have a certain effect. By a series of experiments, influence of the discharge pipe to evaporator performance can be obtained. This is also reflects of the uneven liquid distribute and air velocity.
Keywords: Discharge pipe; Liquid-distributor; Air velocity; Evaporator
