| 1. | New design of control system and communication technology of air - conditioners 一种空调控制系统及通讯技术设计新思路 |
| 2. | In this paper the design and realization of power control system used for air - condition in electric locomotive is performed . it includes two parts which is software section and hardware one 本文完成了电力机车空调控制系统的设计与实现,共分为硬件和软件两个部分进行阐述。 |
| 3. | By means of variable frequency and adjustable speed , the variable air volume air conditioning automatic control system saves energy through setting different static pressure values in different time periods 变风量空调控制系统以变频调速为手段,分时段设定静压值以实现节能。 |
| 4. | The key points of the air - condition system designing are : firstly , selecting the control rules . now the more often used control rules are pi , pd , pid . but the question is which one fit air - condition control system most 空调控制系统的设计关键在于:一是选择控制规律,目前常用的有pi 、 pd 、 pid控制规律,但究竟哪一种控制规律更适合于空调控制 |
| 5. | There are 10 suite , 57 deluxe standard room , 200 superior standard room of chinese and western style . all rooms are equiped with the air - conditioaer controlled system , close - circuit tv facility , mini - bar and internatinoal and domestic direct dial 酒店拥有10套房57间豪华标房200间中西式高级标准房。全部客房均设有空调控制系统闭路电视设施迷你型酒吧及国际国内直拨电话等。 |
| 6. | In a conventional hvac control system , only air temperature and air humidity are controlled . as a result , the air - conditioned room is always not thermal comfortable enough , and the energy - conservation potentials is ignored either 传统的空调控制系统以室内空气的温湿度为控制对象,结果是空调系统不仅不能提供满足人体热舒适需求的热环境,并且常常忽略了系统的节能潜力。 |
| 7. | 2 utilize matlab simulating optimization design for first - order system with large time - delay and compare their results with the system designed by pid . 3 design the hardware system and software system of the fuzzy intelligence inverter air - conditioner based on genetic algorithms 2 、利用matlab软件对基于遗传算法模糊智能空调控制系统进行仿真,中文摘要基十遗传算法模糊智能变频空调机理的研究并与模糊逻辑控制算法、 pid算法仿真进行对比研究。 |
| 8. | As we all know , occupants " thermal sense is mainly dependent on the six factors : inside air temperature , humidity , air velocity , mean radiant temperature , clothing and metabolism rate . the traditional hvac control system , neglecting other factors concerned with human comfort , only considering the inside air temperature and air humidity and indirectly impacting on occupants by the two parameters control , cannot satisfy the comfort requirement of occupants and is energy wasting as well 传统的空调控制系统以室内空气的温湿度作为控制对象,而实际上影响人体热舒适的因素不仅包括温度与湿度,还有风速、平均辐射温度、人体的衣着热阻和人体的新陈代谢率,人体对环境的冷热感受是这些因素综合作用的结果,因此在很多时候系统并不能满足人体对热舒适的需要而且节能性较差。 |
| 9. | In this thesis , the decoupling unit of vav system is designed in the way of feedforward conpensation . then the transfer function matrix of the feedforward conpensation decoupling unit of the 5 inputs & 5 outputs vav system is worked out . the decoupling conpensation unit can change the transfer function matrix of the open loop and closed loop control system into diagonal matrix , so that the coupling among the five control loops is eliminated , and vav system is decoupled 本文采用前馈补偿法设计了变风量空调系统的解耦补偿器,并得出了五输入、五输出变风量空调系统前馈补偿解耦器的传递函数矩阵,该解耦补偿器可以使本文所研究的变风量空调控制系统的开环传递函数矩阵和闭环传递函数矩阵都变换为对角矩阵,从而解除五个控制回路之间的耦合,使变风量空调系统实现解耦。 |
| 10. | Now tongdy have two branches in hong kong and in chengdu . hong kong office can take charge of southeast asia . through out years development , now tongdy control can supply dozens of controllers for hvac and six series gas monitors controllers for ambience gas detection and control 公司拥有强大的技术开发和产品设计力量,依托于中关村众多高校及中科院的人才优势,以及我公司深厚的计算机技术背景,已在空调控制系统的产品开发系统集成方面拥有自主产权,并已取得了骄人的业绩。 |
