What does the solar water heater swimming pool project need? Is it a collector or something?

Do a good job in the swimming pool project of solar water heater: firstly, calculate the required heat collection area and the capacity of the engineering water tank according to the water consumption of the swimming pool; Secondly, according to the project budget, surrounding environment and sunshine duration, determine the heat collector: heat pipe or flat plate, or air energy water heater, with different costs; Then, according to the actual situation of the swimming pool project, design drawings to determine the placement position of the collector; Location of engineering water tank and laying of water pipeline, etc.

Solar water heater is a device that converts solar energy into heat energy and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, with vacuum tube solar water heaters as the main one, accounting for 95% of the domestic market share. Vacuum tube household solar water heater consists of collector tube, water storage tank, bracket and other related parts. The conversion of solar energy into heat energy mainly depends on the vacuum collector tube, and the principle of hot water floating and cold water sinking is used to make the water produce microcirculation and reach the required hot water.

Photothermal utilization: it collects solar radiation energy and converts it into heat energy through interaction with matter for utilization. At present, there are three kinds of solar collectors that are used most, namely flat plate collectors, vacuum tube collectors and focusing collectors. Solar power generation: the large-scale utilization of solar energy in the future will be used for power generation. There are two main ways to use solar energy to generate electricity:

① Optical-thermal-electrical conversion. That is, using the heat energy generated by solar radiation to generate electricity. Generally, solar collectors are used to convert the absorbed heat energy into working medium steam, and then the steam drives the gas turbine to drive the generator to generate electricity. The former process is photothermal conversion, and the latter process is thermoelectric conversion.

② photoelectric conversion. Its basic principle is to directly convert solar radiation energy into electric energy through photovoltaic effect, and its basic device is solar cell.

Photochemical utilization: This is a photoelectrochemical conversion method that uses solar radiation energy to directly decompose water to produce hydrogen.

Photobiological utilization: the process of converting solar energy into biomass through photosynthesis of plants. There are mainly fast-growing plants (such as firewood forests), oil crops and giant algae.

principle of operation

Sunlight shines on the black heat absorption layer of the second glass through the first glass of the heat absorption tube to absorb the heat of solar energy. Because the two glasses are vacuum insulated, the heat transfer will be greatly reduced (radiation heat transfer still exists, but there is no heat conduction and convection), and most of the heat can only be transferred to the water in the glass tube, so that the water in the glass tube can be heated, and the heated water will gently enter the insulated water storage tank along the heating surface of the glass tube, and the water with relatively low temperature in the barrel will enter the glass tube along the backlight surface of the glass tube for replenishment.
