你知道真空管式和平板式热水器两者的差异是什么吗?
很多人以为太阳能的真空管式热水器和平板式热水器是相同的,其实它们大有不同,下面小编给大家介绍下真空管式热水器和平板式热水器的差异。
Many people think that solar energy's vacuum tube water heater and flat water heater are the same, in fact, they are very different. Here's the difference between vacuum tube water heater and flat water heater.
家用太阳能热水器一般按自然循环方式工作,没有外在的动力。而真空管式太阳能和平板式太阳能在循环管路方面有很大不同。
Household solar water heaters generally work in a natural circulation mode without external power. Vacuum tube solar energy is different from plate solar energy in circulation pipeline.
1.真空管式太阳能热水器为直插式结构,热水通过重力作用供给动力。
1. Vacuum tubular solar water heater is a direct plug-in structure, hot water supplies power through gravity.
2.平板式太阳能热水器通过自来水的压力(称为顶水)供给动力。而太阳能集中供热体系均采用泵循环。由于太阳能热水器集热面积不大,考虑到热能损失,一般不采用管道循环。
2. Flat-panel solar water heater supplies power through the pressure of tap water (called top water). Pump cycle is used in solar central heating system. Because the solar water heater collector area is not large, considering the loss of heat energy, pipeline circulation is generally not used.
3.吸热进程也不相同
3. The endothermic process is also different.
真空管式热水器的吸热时,太阳辐射透过真空管的外管,被集热镀膜吸收后沿内管壁传递到管内的水。管内的水吸热后温度升高,比重减小而上升,形成一个向上的动力,构成一个热虹吸体系。随着热水的不断上移并储存在储水箱上部,一起温度较低的水沿管的另一侧不断补充如此循环往复,终究整箱水都升高至一定的温度。
When the vacuum tube water heater absorbs heat, the solar radiation passes through the outer tube of the vacuum tube and is absorbed by the collector coating and then transferred to the water in the tube along the inner tube wall. After the water in the pipe is absorbed heat, the temperature rises, the specific gravity decreases and rises, forming an upward motive force and constituting a thermosiphon system. As the hot water moves upwards and is stored in the upper part of the tank, a lower temperature water is added to the other side of the pipe so that the whole tank water is eventually raised to a certain temperature.
平板式热水器,一般为分体式热水器,介质则在集热板内因热虹吸自然循环,将太阳辐射在集热板的热量及时传送到水箱内,水箱内通过热交换(夹套或盘管)将热量传送给冷水。介质也可通过泵循环实现热量传递。
Flat-plate water heaters, generally split water heaters, the medium in the collector plate due to the natural cycle of thermal siphon, solar radiation in the collector plate heat transfer to the water tank in time, the water tank through heat exchange (jacket or coil) heat transfer to cold water. The medium can also transfer heat through pump circulation.
