制冷剂

Stabilization of system is flux of compressor is equal to flux of capillary tube.

本文把制冷剂流量作为系统的基本参数，系统模型的收敛条件为压缩机的质量流量和毛细管的质量流量相等。

Simulation of capillary tube:Choice of capillary tube is related with pressure of condensation、state of super-cooling、pressure of evaporation and so on.

毛细管中的制冷剂流速很高，流过毛细管的时间很短，毛细管进出口状态的影响认为是即时的，故采用稳态模型。

The impacts of refrigerant charge amounts and capillary tube lengths on the refrigeration system are studied through experiments.

通过试验的方法研究了空调器制冷剂充注量与毛细管长度对制冷系统的影响，得出了相应的试验曲线，找出了最佳匹配结果。

Air is regarded as the best refrigerant to substitution of the CFCs.

空气无毒无害，作为制冷剂可以被认为是氟利昂的最佳替代物。

Yet the CFCs already in the air are still doing their dirty work.

但是空气中现有的氟利昂制冷剂还在继续肆虐。

So the model has good adaptability for air source heat pump water heater/chiller running in winter.

该模型为分布参数模型，且考虑了制冷剂侧两相流对换热的影响，具有很强的适用性。

The amount of ozone-eating chlorofluorocarbon in the atmosphere is dropping faster than anyone expected;the chemicals should peak around the year 2000,then decline.

在大气中会侵蚀臭氧层的氟利昂制冷剂的含量，其降低的速度超出所有人的预期；这种化学物质的量应该在公元2000年达到高峰，之后才下降。

Hydrofluorocarbons are new potential fire suppressions due to the character of effective, nontoxic and low global environmental impact and widely used in industry as replacements of the ozone-destroying chlorofluorocarbon and halon fire suppression agents.

氟代烷烃因其高效、无毒、臭氧消耗系数小的特点，被公认为新型的极具开发潜力的发泡剂、制冷剂及火焰抑制剂，其商业产品已日益成为臭氧耗损严重的氟氯昂和氯氟烃类化合物的替代物。

They don't employ chlorofluorocarbons as refrigerating agents, and they can be driven by lower grade energy such as solar energy and industrial waste heat.

吸附制冷采用无CFCs的制冷剂，可以直接由太阳能、工业余热等低品位能源驱动，是节能、开发利用太阳能等新能源的有效工具。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
