The forth chapter analyzes the physics processes of heating exchange in gfeenhouse , uses the principium method to set up the dynamic model of greenhouse temperature based on heating balance 第四章分析温室内热交换的各个物理过程，运用机理分析法，建立了基于热平衡的温室温度动态模型，以该模型为依据，建立了温室加温时室内温度模型。
As the validation test , the system is applied to three barrier stations on suzhou xitang river for measuring and controlling indoor tempeature and etc . it proves that this approach is feasible , and the system is of good performance 作为本文方法的可行性的测试与验证,文章给出了利用该嵌入式web对苏州西塘河的3个闸站的室内温度等物理量进行采集与控制。
The devices aim at a 25 per cent reduction in the emission of particulate matters . in 20022003 , the department supported the government property agency s proposal of shortening the air conditioning hours and setting the indoor air temperature at 24 在二零零二至二零零三年度，本处支持政府产业署的建议，把入境事务大楼的供应空气调节时间缩短，并把室内温度设定在摄氏24度，以节约能源。
( 4 ) the paper compares the economical efficiency of the vrv heat pump air condition system to the traditional heating systems . form the results , nearly 740 , 000 yuan can be saved when this system is be used to maintain 18 ? indoors every year 通过采暖费用与vrv热泵空调系统运行费用计算及比较可知，采用vrv热泵空调采暖在保证冬季室内温度+ 18条件下，每年可节省近74万元，经济效益十分明显。
The results indicate that thermostatic radiator valves can regulate and control indoor temperature effectively and save heating energy consumption , and that using thermostatic radiator valves can produce good economic benefit because the initial investment is lower and the payout period is shorter 分析结果表明散热器恒温控制阀可以有效调控室内温度和节约供暖能耗；恒温控制阀初投资低和投资回收期短，在实际应用中可以产生良好的经济效益。
With the help of it , air - conditioner , namely fuzzy inverter air - conditioner , has the intelligence character that temperature is adjusted automatically , continuously , according to temperature ' s change indoors . all this will avoid frequent switches of the compressor and economize energy 控制系统能够根据室内温度变化，连续、动态、实时地对压缩机变频调速，即调节温度，这样克服了传统空调器在室温波动时压缩机工作状态频繁切换的问题。
Every parameter of microclimate in greenhouse was analyzed respectively by using the model , the results are that the temperature and humidity outside are the most important factors respectively , and solar radiation and lai strongly influence the temperature and humidity inside 利用该模型对影响温室小气候的各个因子进行单独分析，其结果是：室外温度和湿度分别是影响室内温度和湿度的最主要因子，太阳辐射和叶面积指数对室内温湿度都具有很大的影响。
That means the controlled temperature al1ow waving in a range in a period . when the change of the temperature indoor is out of the range we enacted , the system begin to regulatc . compensate the windage last time leave behind } before decide the heatsupply parameter for the next time 即允许被控室内温度在一段时间内存在一定幅度的波动，当室温变化幅度超过设定值时系统开始调节，在确定下一时间段的供热参数之前对上一时间段的遗留偏差在短时间内给予补偿。
