It is heat - resistant , durable , has high degree of adapting capacity , sound - proof , anti - frosting and able to reduce the radiation of the sun 具有很强的隔热性、耐久性和适应性的采光节能防噪声功能、防结霜，降低阳光辐射等功能。
This machine is provided with function of anti - frosting and auto frost removing , and this can make sure the machine work stably under the low temperature 机组具有防结霜和自动化霜功能，确保机组在低气温环境条件下性能稳定可靠。
In our country , most buses still use cctxv system and ccot system to control air - conditions . these ways have not a higher accuracy in control 在汽车空调控制中，防止蒸发器结霜，使空调高效运行和控制车厢内的温度是控制的根本任务。
In addition , the effect of several parameters including the type of the blast , the spacing of fins , and the fin thickness on the frost performance was discussed 讨论了改变风机类型、翅片间距以及翅片厚度在内的几种设计参数对结霜性能的影响。
A forced convection finned tube exchanger model with constant blast volume was constructed and its reliability was confirmed by the performance test 摘要建立了恒流条件下的强制对流翅片管式换热器的结霜模型，并用实验结果验证了模型的可靠性。
But the frost , which is accumulated on the evaporator for certain surrounding conditions , can degrade the performance of ashp and the periodical defrost is necessitated 然而机组的本身特点决定了在一定环境下必然存在结霜的现象，因此需要周期性地除霜。
The next morning , the freezing temperatures awoke the seasonal park ranger before dawn ? just in time for him to capture this frosty , foggy field at sunrise 第二天早晨，冰冻的温度把这个季节公园护林员惊醒，天还没亮，刚好来得及让他在太阳升起来之前，拍下这结霜、有雾的大地。
Thermal character of the exchanger was simulated during the frost time , considering both the frost model and the fan - coil performance curve under the engineering situation 将结霜模型和风机性能曲线联合起来考虑，在更加切合实际的情况下，模拟了换热器在结霜工况下的热力性能。
It is shown that the fin efficiency , air flow - rate , and fin performance are significantly decreased while pressure of the air side is increased when frosting occurs at the exchanger 研究发现，换热器结霜引起了翅片效率、空气流通率及翅片性能的显著降低，同时还伴随着空气侧压力降上升。
The property ' s feeding sites and frost - free water areas make it suitable for african elephants , which can stand 10 feet tall at the shoulder and weigh more than 10 , 000 pounds , officials said 人员的说法，这家牧场的草地以及永不结霜的河流非常适宜非洲象的生长。匹兹堡动物园及该动物园的ppg
