Now, there're tens of manufacturers, including Yangdong Stock which produces small-bore (80, 85) multi-cylinder diesel engineers; Jiangsu Shuangdeng Power Supply which produces valve-controlled sealed lead-acid battery, sealed traction battery and gelled battery; Jiangsu Feichuan Stock which produces gear and auto parts; Jiangsu Gangyang which produces crankshaft connecting rod assembly of motorcycle engine; Jiangsu Yafang Cooling which produces medium and heavy duty truck air conditioning system; Jiangyan Sutai Friction Material which produces clutch facing, brake block and brake band; and Jiangsu Pacific Precision Forging which produces cold precision forging, cold extrusion special-shaped part and gear.

现有生产厂家数十家，主要是生产80、85小缸径多缸柴油机的扬动股份有限公司；生产阀控密封铅酸蓄电池、密封牵引蓄电池、胶体电池的江苏双登电源有限公司；生产齿轮、汽车零部件的江苏飞船股份有限公司；生产摩托车发动机曲轴连杆组件的江苏罡阳股份有限公司；生产中重型卡车空调系统的江苏亚方制冷有限公司；生产离合器面片、刹车片、刹车带的姜堰市苏泰摩擦材料厂；生产冷精锻、冷挤压异形零件、齿轮的江苏太平洋精密锻造有限公司等企业。

The central heating system seems to have gone wrong .

中央空调系统好象坏了。

This user information such as the distance to the central office in the central air-conditioning system can be managed.

此用户到局端的距离等信息都可以在中央空调系统中得到管理。

The development of the building equipment automation makes the centralized control of air conditioning possible.

自动化及电子技术的发展和完善，使空调系统的集中控制成为可能。

In a typical general office building, the difference in fan cfm between a constant volume system and the average flow in a VAV system is typically 30%- 40%.

在一个典型的普通办公楼，差额采用CFM风扇之间的恒容体系和平均流量的变风量空调系统通常是30 ％- 40 ％。

Introduces the characteristic and function of balance valve and its application in engineering.

讨论了空调系统水力平衡问题，介绍了平衡阀的特性、作用及其在工程上的应用。

As long as the root of the characteristic equation is within the unit circle of z-plane and the corresponding PID parameter is got, the closed loop control system is sure to be stable. Although the root of the characteristic equation can vary within the unit circle of z-plane,different value may affect the control property differently.

本文所采用的这种确定PID参数的方法，虽然可以使特征方程的根在z平面的单位圆内任意取值，但各种取值情况对变风量空调系统的控制品质的影响却不同，因此，要对各种特征方程的根的取值情况进行寻优，本文采用遗传算法对特征方程的根进行寻优，从而使控制器的参数得以优化。

The high-leaving temperature chiller is very important equipment for an independent temperature and humidity control system, and also it was widely used in industry process.

高温冷水机组是温湿度独立控制空调系统中的重要设备，也是工业生产过程中常常用到的大型装备。

As chiller for central air-conditioning system is the largest power equipment in the project, the crucial importance of energy-saving impact.

由於冰水机是中央空调系统设备中最大耗电的项目，对节能具有关键性重要的影响。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
