The heat collector

The heat collection element in the system, its function is equivalent to an electric water heater electric heating tube. And electric water heaters, gas water heater is different, the solar heat collector with heat radiation of the sun is, therefore, the heating time can only in the sun during the day, so sometimes the need for auxiliary heating, such as boiler, electric heating.

Thermal insulation water tank

The thermal insulation water tank and electric water heater, is a container for storing hot water. Because the solar water heater can only work during the day, and people in generalin the evening to use hot water, so we must through the heat preservation water tank to store the heat collector in the daytime output hot water up. Volume is the sum of theamount of hot water every night. With enamel inner container bearing heat preservation water tank, good effect of heat insulation, corrosion resistance, the water quality is clean,the service life of up to 20 years.

Connecting pipe

The hot water from the collector is conveyed to the heat preservation water tank, cold water from the heat preservation water tank will be transported to the collector loopchannel, make the whole system to form a closed. Reasonable design, is connected with the circulating pipeline right of solar system whether can achieve the best work condition is essential. Hot water pipe antifreezing insulation processing must be done. Pipe must havevery high quality, ensure that there are more than 20 years service life.

Control center

The difference of solar hot water system and ordinary solar water heater is the control center. As a system, monitoring, operation, regulation and other functions of the control center is responsible for the entire system, technology is already available through the normal operation of the Internet remote control system.

Solar water heating system control center is composed of computer software and theelectrical box, a circulating pump which.

Heat exchanger

Plate type welded the advantages of detachable plate type heat exchanger efficiency,compact heat exchangers, making up the defect of shell and tube heat exchangerefficiency is low, covers an area of large heat exchanger. Plate shell heat exchanger heat transfer plate wavy oval, circular plate increases heat long, greatly improving the heat transfer performance. Widely used for heat exchange situation, the conditions of high temperature and high pressure.

Characteristics of the

The international standard ISO9459 XIX XX 15 put forward the scientific classification ofsolar hot water system, the classification that is according to the seven characteristics of solar hot water system, each of which features are divided into 2-3 types, thus constitutinga solar hot water system and rigorous classification system, as shown in the table.
