The way solar water heaters share with natural gas water heaters is that the solar outlet pipe only needs to be connected to the inlet pipe of the gas water heater in this way, when the solar water temperature is not high. enough, gas can be used to heat it.
Photothermal use of solar water heater
It collects energy from solar radiation and converts it into thermal energy by interaction with matter for use. Currently, the most commonly used solar energy harvesting devices include flat plate collectors, evacuated tube collectors and focused collectors. Solar Power Generation: Large-scale use of solar power in the future will be used to generate electricity.
Basic working principle
Cold water enters the water heater and flows through the body of the water-gas connection valve sou the action of a certain difference in pressure of the flowing water, the water-. The gas link valve is pushed and the DC power is pushed at the same time. The microswitch turns on the power and starts the pulse igniter. At the same time, the gas transmission solenoid valve is opened. until the ignition has successfully entered the normal operating state. This process lasts about 5-10 seconds, when the gas water heater encounters problems such as lack of water or insufficient water pressure, lack of electricity, lack of gas, excessive water temperature. hot water, accidental switching off, etc. During the working process or the ignition process, the pulse igniter will detect the signal returned from the detection needle, automatically cut off the power supply, and the gas transmission solenoid valve immediately returns to the. original state of normally closed valve in case of lack of electrical powerelectrical, meaning the gas path has been cut off at this time and the gas water heater is shut off for safety reasons.
Gas water heater
It refers to a type of gas that uses gas as fuel and transfers heat to cold water circulating through the heat exchanger. heat by combustion and heating to achieve the purpose of preparing hot water. It is mainly composed of valve body, main burner, small burner, heat exchanger, safety device, etc.
Is there a relationship between coal, oil, natural gas and solar energy?
Natural gas is more profitable. Although solar energy costs nothing, it relies on the sun to produce heat. Guangdong has longer rainy days and fewer sunny days. Solar energy cannot be used when it rains. Although natural gas consumes gas, it is not aAffected by weather conditions, natural gas is therefore more profitable.
It's important. Coal, oil and natural gas all store solar energy.
Oil is derived from ancient organic materials. Over long geological periods, large numbers of marine organisms have reproduced in the ocean. Their dead remains sank to the seabed with the sand and accumulated layer by layer over the years, isolated from the outside air after being decomposed by bacteria. , and Under the action of high temperature and pressure in the formation, the biological remains gradually decompose and turn into oil and natural gas.
Coal is derived from ancient plants. At that time, after a large number of ferns died, the remains sank into water and were buried deep underground. Under the action of anaerobic bacteria (microorganisms that do not like oxygenne) and the wave movement of the earth's crust, the content. Hydrogen, oxygen and nitrogen slowly decrease, the carbon content increases relatively, and the remains of the plant gradually turn into peat, lignite, bituminous coal and even anthracite.
Coal, oil and gasIt is formed by animals and plants and is the product of solar energy.
