Fluorine Chemical Company as the leading enterprises in this area does have the technical capacity and technical reserves, such as alternatives to halon F227, or the field of non-refrigerant used.

氟化工公司在这一领域的龙头企业确有足够的技术能力，如对哈龙F227，还是非传统安全领域，制冷剂的替代技术储备。

Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes.

实际上，Teflon炊具的核心物质碳氟键有着广泛用途，我们还把它用到衣物、润滑剂、制冷剂、麻醉剂、半导体，甚至血液替代品里面。

The difference between these two amounts of heat content is the amount of work being done by each pound of refrigerant as it passes through the evaporator and picks up heat.

区别这两个数额的热含量是大量的工作正在做的每一磅的制冷剂，因为它流经蒸发器，并拿起热量。

The enhancement factor of boiling heat transfer was independent of refrigerant.

试验管的沸腾换热强化倍率与制冷剂的关系不明显。

In some conventional fan revolution speed control methods, variable control of the number of revolutions of a cooling fan is performed by a process comprising steps of detecting an actual temperature of cooling target fluid, ie fluid to be cooled by the cooling fan, such as hydraulic oil and circulating radiator cooling water for cooling an engine (such cooling water is hereinafter referred to as coolant), determining a target fan revolution speed by a system of a proportional integral control unit based on the difference between the actual temperature detected and a target temperature, and changing the fan revolution speed based on the target fan revolution speed so as to bring the actual temperature of the cooling target fluid down to the target temperature.

在一些传统风扇转速控制方法，控制变量的数目革命的一个冷却风扇，是由一个过程组成的步骤检测到一个实际温度冷却目标流体，即流体被冷却，由冷却风扇，如液压石油和散热器循环冷却水用于冷却发动机（如冷却水是以下简称为制冷剂），确定一个目标风扇转速由一个系统的比例积分控制单元基础上的差异，实际温度检测和目标温度，并改变风扇转速的基础上，针对风扇转速，使实际温度的冷却液指标下降到目标温度。

R12 on the ozone layer due to the destruction of the requirements of the developed countries for environmental protection from 1996 to start using refrigerant R134a Automotive Air-conditioning and the construction of air-conditioning at home in a similar, it is often installed in the compressor engine, and with a belt drive, the condenser installed in the car in front of the radiator, and evaporator in the car inside, and work out from the evaporator of low pressure gaseous refrigerant flows through a high-pressure high-temperature gas compressor After cooling condenser cooling tube cooling into the low-temperature high-pressure liquid, through the desiccant dryers and storage of buffer, and then to a more stable flow of pressure and flow expansion valve, the final expenditure and the flow of relief evaporator.

由于R12对大气臭氧层的破坏，出于环保的要求发达国家从1996年开始改用R134a做制冷剂汽车空调的构造和家用的分体空调类似，它的压缩机往往是安装在发动机上，并用皮带驱动，冷凝器安装在汽车散热器的前方，而蒸发器在车里面，工作时从蒸发器出来的低压气态致冷剂流经压缩机变成高压高温气体，经过冷凝器散热管降温冷却变成高压低温的液体，再经过贮液干燥器除湿与缓冲，然后以较稳定的压力和流量流向膨胀阀，经节流和降压最后流向蒸发器。

The refrigerants that are used in the foaming agents that help to insulate and those in the circuit used in refrigerating should only have an ozone depleting potential of zero.

在中所使用的发泡剂帮助隔离和在制冷只能用具有零消耗臭氧潜能电路的制冷剂。

The coolant flows through the thin flattened tubes that make up the core of the radiator and is cooled by the air flow through the radiator.

制冷剂流向薄管，这是水箱的核心，液体被进入到水箱的气流冷却。

ABSTRACT Introduces three methods that can adjust refrigerating output according to the variation of load aimed at the varying duty condition during the practical operation process of refrigeration system,frequency inverter technique,parallel unit with several compressors and liquid refrigerant storing method.

摘 要针对制冷系统实际运行过程中存在的变负荷工况，介绍三种根据负荷变化调节制冷量的方法：变频技术、多机并联压缩机组以及液体制冷剂储存方法。

Then the generalized equation that is implicit and used to calculate saturated vapor density of refrigerant mixtures was proposed.

进而给出了计算混合制冷剂饱和气体密度的通用方程，该方程是隐式的。

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。
