What are the components of the solar water heater and what role?
The solar water heater is a great achievement in the application of solar energy industry, it is for people to provide environmental protection, new water heater products, health safety and energy saving, solar water heater is to absorb solar radiation heat, heating and cooling for people using energy-saving equipment in life and production.
system compositionThe collector: the heat collecting element in the system. The function of electric equivalent electric water heater in the tube. And the electric water heater, gas water heater is different, the solar collector is the use of the heat radiation of the sun, so the heating time are only in the sun day.The heat preservation water tank: tank insulation and electric water heater, hot water is stored container. Because the solar water heater can only work during the day and at night, people generally use hot water, it must be through the heat preservation water tank to store the collector in the daytime output hot water. Volume is every night with hot water. The amount of the sum an enamel container bearing water tank insulation, good heat insulation, corrosion resistance, water quality, service life of up to 20 years.
The connecting pipe: the hot water from the collector is transported to the heat preservation water tank, the cold water from the water tank insulation transported to the collector loop channel, make the whole system to form a closed circulation pipeline connection. Reasonable design, the right of the solar system is able to achieve the best working conditions is very important. Hot water pipes must be insulated. The pipe must be of high quality, which has more than 20 years of life.Per square meter flat solar heat collector average normal sunshine day, can produce the equivalent of 2.5 kwh of heat, annual savings of 200 kilograms of standard coal, can reduce emissions of more than and 700 kg CO2. Extensive use of solar water heaters, including domestic hot water, heating, air conditioning, pollution and greatly improve the earth will save money at the same time.
