When you create a distributed application , you might find it difficult to test the application in the manner in which it will be used 在创建分布式应用程序时,您可能很难做到对其进行实际使用条件下的测试。
The object to study in this paper is the electric heat reservoir boiler , which is used to supply heat water and bask for the resident population . the use of the system define the character of the output medium with the lower request on quality and parameter , at the same time , it ask the boiler should has the higher character on the respect of the cost , reliability , economy , and so on . hence , the paper carefully design and study the system for the choice and design of the boiler core heating componet , the lay of the heat exchanger , the working status of the heat reservoir equipment , the adjustment and control mode of to supply heat water . the study work mainly include underside some contents , forexample : 1 . to confirm the heat medium parameter to adapt the requirements of the most of the heating equipments and to design the instruction of the boiler and heat reservoir as simple as possible 围绕上述原则,本文从电热锅炉核心加热元件的选型及设计、换热面的布置、蓄热设备的运行工况、供热的调节方式以及控制方法进行了较细致的研究和计算,具体研究工作有以下几个方面: 1 .根据使用要求,确定适用于多数采暖设备的热介质参数,设计在结构型式上尽可能简单的锅炉和蓄热器; 2 .对制造加热元件电热管的各种材料进行了对比和分析、在结构尺寸上进行了仔细的分析和计算,根据实际使用条件给出合理的设计,使其具有较高的可靠性和使用寿命; 3 .对不同换热面布置形式进行传热分析。
