Solar Water Heater is a kind of household or commercial equipment that uses solar energy to heat water, which belongs to the category of light and heat utilization in solar power generation equipment. The following is a detailed introduction to the categories of Solar Water Heater:
I. Basic definition
Solar Water Heater is a device that uses a solar collector to convert
Solar Light energy into heat energy and then heats water through heat conduction. It works with a renewable energy source - solar energy, which is an environmentally friendly and energy-saving way to supply hot water.
Second, the working principle
The working principle of solar water heaters is mainly based on the conversion of light and heat. When sunlight hits a solar collector (such as a vacuum tube or flat plate collector), the collector absorbs solar light energy and converts it into heat energy. The heat energy is then transferred to the water in the collector by means of thermal conduction, so that the water temperature gradually rises. The heated water flows into the storage tank through the pipe for storage for users.
Three, product classification
According to the different parts of the heat collection, solar water heaters can be divided into the following categories:
Glass vacuum tube solar water heater:
Features: Using the heat pipe effect in the vacuum tube and the principle of hot water floating up and cold water sinking, the operation efficiency is high.
Application: Widely used in families, small business places, etc.
Flat panel solar water heater:
Features: large heat collection area, long service life, suitable for large hot water systems or large area heat collection occasions.
Applications: commercial buildings, schools, hospitals, etc.
Ceramic hollow flat panel solar water heater:
Features: light and heat absorption ratio is high, the absorption rate is even higher than the national standard.
Application: High efficiency hot water systems for specific needs.
Four, components
Solar water heaters are mainly composed of the following components:
Collector: The part that absorbs the sun's light energy and converts it into heat energy, and is the core part of a water heater.
Tank: A container for storing heated water, usually made of insulating material to maintain the temperature of the water.
Bracket: Structural components that support the collector and storage tank to ensure the stability and safety of the entire water heater.
Piping: Connecting the collector, the storage tank and the user's piping system for the circulation and supply of hot water.
