使冷却的

First, a system for providing liquid refrigerant subcooling (10), subsequent to the subcooling accomplished by the primary condenser of an air conditioner, refrigeration or heat pump system, by means of evaporative cooling utilizing the condenser water of said air conditioner, refrigeration or heat pump system and/or some other water supply to wet the surface of the subcool heat exchanger and then passing the cold, dry building exhaust air (13) required for good indoor air quality across the wetted surface of the subcool heat exchanger or by using building exhaust air only to conductively subcool.

首先，一个提供液态制冷剂过冷的系统(10)，在由空调、制冷或热泵系统的主冷凝器实施完成过冷之后，通过蒸发冷却，利用所述空调、制冷或热泵系统的冷凝器水和/或一些其它水源来润湿过冷热交换器表面，然后使为达良好质量室内空气所需的建筑物干冷排气(13)通过穿过过冷热交换器的润湿表面，或只利用建筑物排气以传导方式过冷。

The ice/liquid mixtures of the coolant and the sample solution were respectively added in the Dewar bottle and the sample container to precool for 2~3 hours under stirring. Then some of the coolant liquid was replaced with coolant ice, the motor stirrer was restarted, and the temperatures were read from the Beckmann thermometer.

实验时，先调节寒剂的组成使其凝固点低于待测溶液的凝固点～2℃，然后分别在保温瓶和凝固点杯中加入寒剂和待测溶液的冰水，启动搅拌器预冷却2~3小时，接着更换保温瓶中的寒剂冰水，重新启动搅拌器，记录贝克曼温度计读数。

Such systems must be designed to keep the lighting uniform and repeatable, keep the system's internal electronics cool, be able to withstand the harsh environments found within the plant (e.g., daily washdown), and be simple and inexpensive to fabricate.

这种系统的设计必须使照明均匀，重复性好，保持系统内部电子的冷却，能够承受在植物中发现的恶劣的环境，以及简单、成本低廉的制造。

--- Disclosed are a process and plant for the recovery of water from humid air, in which at night cool humid air is passed through an adsorbent medium layer which adsorbs water from the air and in which, by day, air heated by solar energy up to a temperature which is above the ambient temperature is passed first through this layer to absorb water from the layer and then is cooled down so that the water condenses.

摘要---透露，是一个过程和植物为香港经济复苏的水从潮湿空气，在这种在夜间凉爽潮湿的空气是通过一吸附剂的介质层，其中吸附的水，从空中和在其中，由天，空气加热太阳能能源最多的温度是高于环境温度是通过第一，通过这层吸收水层，然后是冷却下来，使水凝结。

Transfer the filtrate to a tared beaker, evaporate to dryness without charring, dry at 105 for 1 hour, cool in a desiccator, and weigh: the difference between the weight of the residue and the weight obtained from a blank determination does not exceed 12.5 mg (0.25%).

将滤液转入已称重的烧杯，105°下干燥1小时，在不烧焦的前提下使其蒸发至干，在干燥器中冷却，称重。测得的残渣重量与空白测定中得到的残渣重量之差不超过12.5 mg (0.25%)。

Aiming at the problems occurred in the analytical process of determining the total phosphorus in industrial circulating cooling water by ammonium molybdate spectrophotometry and based on the experience summary,the original analytical method has been improved.

针对用钼酸铵分光光度法测定循环冷却水中的总磷在实际分析过程中遇到的一些问题，经过总结经验，改进了原有的分析方法，降低了测定中的干扰因素，提高了一次分析结果的准确可靠性，使分析结果更为准确可靠。

First, pre-heating the preform; then stretching it with stretch-rod meanwhile blowing it so that the preform becomes the real shape of mold of the bottle; finally, cooling the product and taking it out mold.

本课题所论述的PP瓶的拉伸吹塑成型是采用二步法，即成型好的瓶坯先预热，后用拉伸杆拉伸型坯并通入压缩空气吹胀型坯使之贴紧模具型腔，把模腔的形状与尺寸赋予制品，然后冷却最后脱模。

Rated at extraction conditions, one pump is running, because the cycle of water to reduce the system's water resistance decrease the flow of water pumps 12274T / H, head will drop to 15.0-16.0 m, in the extraction steam turbine at the maximum operating conditions, the recycled water to meet the system requirements to run a pump, because of substantial reduction in the volume of water supplied, so that substantially improve pump head, a direct result of the cooling tower water gushing, increase淋水device with a flow rate of the sink, fill up water in the hot淋水exchange reduce the time and reduces the cooling effect of cooling towers.

在额定抽汽工况下，一台水泵运行，由于循环水量减少、系统的水阻下降，水泵的流量12274T/H，扬程将下降至15.0-16.0米，在汽轮机在最大抽汽工况时，为满足循环水系统要求运行一台水泵，由于供水量大幅度减少，使水泵扬程大幅度提高，直接造成冷却塔涌水，加大淋水装置配水槽的流速，水流在淋水填料上热交换的时间减少，降低了冷却塔的冷却效果。

NF 99 is a heavy duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 99 contains chlorinated additives, fatty oil and special lubricity fortifiers to impart quick release of chip from tool even under extreme high cutting pressure. The low viscosity ensures good cooling and flushing properties, which are essential for high speed machining.

NF 99是一款专为非铁金属而配制的切削油，适用於铜金属、铝金属及其合金的重负荷切削，含有氯化物、脂肪及特殊润滑添加剂，增进其极压及润滑性能，就算在高切削压力下，也能使屑片容易与刀具分离，低的黏度确保了足够的冷却及冲屑性能，都是高速切削所必需。
