容积式热水器设计方案 Design proposals of storage gas water heater 普通燃气快速热水器具有造价低、体积小、安装方便、加热快等优点。但它有如下不足，冬季用于家庭洗澡时，无法同时采暖；其它地方大量用水时，使热水突然变小，变烫；高楼层住户常会遇到水压低，热水器不能正常工作；停水时，更是无法洗浴。容积式燃气热水器，能有效解决以上问题且，建立家庭热水供应系统。Common instantaneous gas water heater has low cost, small size, convenient installation, quickly heating, etc.But it has some defects,such as it can not be used for home heating when someone is showering on Winter; hot water suddenly become smaller and very hot when water is used on other place in same house.Water heater also can not be normally used which be installed on high floor and the water pressure is lower; Can not shower when water supply stoped. Storage gas water heater can effectively solve the above problem and create a family hot water supply system.A 方案一（基础型） A Proposal one(basic model)1 结构、性能及特点(Structure,function and feature)容积式燃气热水器一般采用较大高径比（高度与直径之比）的立式结构，燃烧器在中央最底部;采用双层炉胆，内胆烟管内设有多组齿形热气流阻隔板，烟气出口处设气流阻隔罩，减缓燃烧烟气流速度，保证燃烧产生的热量最大程度地传导到水中；全自动控制系统，可实现意外熄火保护，缺水保护，温度过热保护，保证整个系统安全运行；使用功能上还具有下面的特点：Vertical Structure of using big height- diameter ratio is normally used on storage gas water heater,burner is seted on the middle of the bottom, boiler furnace has two layers,the pipe of inner container has some flue obstructing parts,There is a cover be setted on the outlet of chimney and it can retards the flue gas transfer speed,guarantees the heat be transmited in water furthest.the automatic control system can realizes accident extinct protection, hydropenia protections, temperature overheating protection, guarantee the safty of system running; the functional also has the following features 1.1它是家庭热水供应中心，在淋浴或盆浴的同时，其他地方同样可以用热水洗衣、洗菜、洗碗等；It is the domestic hot water supply center, in the shower or tub at the same time, other place can also use hot water to wash clothes, wash dishes, wash dishes, etc1.2它没有启动水压的要求，冷水可达哪里，热水就送到哪里，特别适合于水压低的高楼层住户；It does not has requirement of the water operating pressure, cold water to where, hot water can be delivered to everywhere based on cold water transmission, particularly suitable for high floor residents which has low water pressure;1.3热水器提前已把需要的热水储存好，即使在使用时停电、停气、停水，都能照常使用热水，解决后顾之忧；The needful hot water has been stored before using,hot water can be used sa usual even no gas, no water supply, no power, solve the trouble back at home.2 技术参数 Technical parameters可用液化石油气、天然气、城市煤气等作为燃料，具体参数如下表。LPG,NG,TG can be used in this appliance.基本参数 Basic parameters气源 gas type燃气压力(Pa) Gaspressure水温控制Temperature of hot water环境温度ambient temperature热效率EfficiencyCOa 液化气LPG28003080080850.10天然气NG2000人工煤气TG10003 控制原理 Controling principle控制器通过测试常明火的存在，来决定燃气供气系统是否给主燃烧器供燃气；通过置于热水器水中的感应器自动感应水温与预设水温的关系来决定主燃烧器是否开启。因此，整个系统不受外部供电系统的影响，同时具有熄火保护功能和超温保护功能，从而实现运行安全。Controller decide whether to supply gas to main burner by checking the existence flame;The temperature sensor automatically control whether to open main burner by checking the difference value between hot water temperature and the setted temperature.So,the whole system can not be effected by external power supply, and has flameout protection and overheating protection fuctions, so as to guarantee the safety operation.。5 结论Conclusion5.1 立式结构，受热方式独特，先进合理； Vertical structure, unique heating way, advanced and reasonable5.2全自动控制，实现“无人值守”； automatic control, to achieve the unattended5.3 高效燃气系统，使燃烧彻底，无污染，节约能源；Efficient gas conbustion system, make burning thoroughly, no pollution, save energyA 方案二（两用型） Proposal two(multi-purpose model)另外还有比较复杂的两用型，既可以取暖又可以供热。其控制系统及燃烧系统更加复杂。但基本原理与简单型类似，通过一个加热系统和一个储热系统来实现热水供应。 There are some other multi-purpose models which have c
