subject: Bringing Home Appliances Products Jiemi Of Solar Water Heaters - Bringing Home Appliances, Solar [print this page] New round of Appliances to the countryside The results of the bidding on May 14 in Beijing announced. In "
Home Appliances The countryside "in the second round of expansion,
Solar water heaters Been incorporated, "home appliances to the countryside" policy started, no doubt the development of solar energy companies new impetus. However, compared with many other home appliances, solar energy industry as a whole less competitive.
Solar Water heater Principle:Solar water heater is a light-heat conversion device, different from the traditional natural advantage, such as drying, lighting. Vacuum tube solar water heater is the core of the structure of his guts like a stretch of the thermos bottle, a vacuum between the inner and outer layers. Including the use of the surface of glass coated with a special process spectral selective absorbing coating, for maximum absorption of solar radiation.
By sunlight, photons impact coatings, solar energy into heat energy, water absorbs heat from the outer coating, water temperature, density decreases upward movement of hot water, while the proportion of cold water down. Water remains in the upper part of the tank. Hot water heating solar water heater in case the temperature has little to do with the outside world, mainly depends on the light. When the open kitchen or bathroom faucet any time, the hot water heater will depend on the natural fall out, the greater the gap, the higher the pressure, the proposed use of DC Habitat seventh floor nozzle (nozzle function, the more the greater the resistance)
As vacuum drying in the air when the pipe temperature can reach about 250, so the tank water or the first time in Sheung Shui to be before sunrise or after sunset and a half hours.
To determine whether the water full of solar water heater?
Solar water heaters generally have An overflow pipe, overflow pipe can determine whether the drainage of water over the state, also can be equipped with water level controller, water full automatic alarm, according to police discrimination.
A long time without water, heat bad will it?
Vacuum tube solar water heaters, high efficiency, in the case of sunny days in summer, less than two days the water temperature up to boiling point, if a long time without water, such as travel, travel to the tank a long time in high temperature and pressure of the state, will promote the ring of aging, accelerated aging of polyurethane, atrophy, and sometimes the exhaust does not flow, too much pressure will make a bad expansion tank, but also furring shorten tank life. Therefore, if you long-term are not at home should arrange for someone else often heat water cold water, or vacuum tube collectors in place to block the sun shelter, to be home, and then removed.
Days of unused water can use it?
Solar water heater for several days without water, are generally used in more hot water, and reach above 70, especially in the summer, sunny weather over two days, the water would boil, to cool down at night will be appropriate to maintain the water temperature of 60 -70 region for a long time, and this temperature region is an excellent bacterial growth in water temperature, so long as several days or without hot water, poor water quality, bacteria and more, to be discharged out, do not take a bath or used boil water for drinking, bathing water on the skin such adverse, long-term use of this water bath will cause skin disease.
