Does solar water heater work at night？
Publish Time: 2019-12-02 Origin: Site
For a container of solar water heater work at night. Because solar water heaters can only work in the daytime, and people usually use hot water at night, so the hot water produced by the collector in the daytime must be stored through an insulating water tank. Volume is the total amount of hot water used every night.

How to Understand the Working Principle of Solar Water Heater？
Solar water heater converts solar energy into heat energy. Heating water from low temperature to high temperature. So as to satisfy people's use of hot water in life and production. The solar water heater is divided into vacuum tube solar water heater and flat panel solar water heater according to its structure. The vacuum tube solar water heater is the main type. The vacuum tube domestic solar water heater is composed of heat collector, water storage tank and bracket and other related accessories. The collector tube makes use of the principle of floating, cooling and sinking of hot water to produce microcirculation and achieve the required hot water.
Heat absorption process for solar water heaters
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 heat absorption, 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, and the lower temperature water is continuously replenished along the other side of the pipe so that the whole tank water rises to a certain temperature.
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.
Circulating pipes for solar water heaters
Household solar water heaters usually work in a natural circulation mode without external power. Vacuum tubular solar water heater is a direct plug-in structure, hot water provides power through gravity. Flat-panel solar water heaters provide 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 small, considering the loss of heat energy, pipeline circulation is generally not used.
What the ways of working at night ?
Use solar water heater to heat water and generate electricity. The high temperature hot water during the day is stored in a large "thermos bottle" water tower. The water tower of the solar water heater should be insulated and stored at night to ensure that it can be heated at sixty or seventy degrees. In fact, the heating of solar water heater water temperature requirements are not high, not frozen hands and feet is enough. Solar steam turbine power generation, hot water through the condenser variable steam power generation. The temperature can reach boiling point, cloudy days slightly lower, can be used to add power battery fire.
Solar water heater has temperature control, pump, water tank and other components, circulating water 50 degrees can be guaranteed. And electricity consumption is also a circulating pump temperature control. One of the ways that solar water heaters work at night is to make a high temperature water tank. Which stores 100 degrees of water during the day and then supplies it for use at night..Jiangsu SunPower Solar Technology CO not only provide a good product. But also provide high quality service.
