and different seasons with the South

Demand determine the market size, the booming solar market is its own advantages of s by the decision. Solar water heaters do not have gas, electricity, or electricity is not small, intelligent control, safe and reliable to use, fast and convenient, environmentally friendly and energy saving.

    Solar water heaters and the South

The source, then the root of solar water heaters should be in the north, and in the north to get a comprehensive application, the solar market is booming, people are bound to ask: Although the North with a good solar water heater, but for the South it? The answer is yes.

As the national government\\ s control, electricity and gas costs have a certain level of improvement, the purpose is to encourage people to use new energy sources, thus, the south of Guangdong, Guangxi and other regions of the solar hot situation. Demand determine the market size, the booming solar market is its own advantages of solar water heaters by the decision. Solar water heaters do not have gas, electricity, or electricity is not small, intelligent control, safe and reliable to use, fast and convenient, environmentally friendly and energy saving.

Some people think that just like solar water heaters in the south tasteless, tasteless gesture. The sun is good you do not want to use hot water in winter, but not want to use. In fact, this idea is completely wrong, large-capacity models of the solar water heater can solve this problem completely, they are water, thermal well, a full sun exposure may be a few rainy days in a continuous supply of hot water. Long rainy season can also use the auxiliary heating, power consumption is only conventional electric water heater 1 / 10, and the safety and long life. Meanwhile, the southern sun in winter and non-monsoon season is not less than the North, and the ambient temperature is high, even if the semi-cloudy day or half-day sun can shower. Now some manufacturers developed solar power can be achieved in the case of non-normal use of solar water heaters, temperature can be described as a sweeping change.

Secondly, Southerners in general have the habit of daily bathing, and water consumption. If long-term use of electricity, gas water heater, would cause great waste of energy. The large-capacity models of water heaters, water is generally 200 liters, equivalent to the water heater or gas water heater 5 to 20 hours produced by hot water, shower and tub for several people.

Again, we all know, in terms relative to the northern, southern life, the level of consumption is relatively high, to accept new things faster, long-term investment for the benefit of a solar water heater, the South generally accepted users. And as energy prices increase, solar energy is also more and more southerners welcome.

Although a variety of reasons, electricity, gas water heater market in the South pre-empted, and heavy use, but this does not affect the rising star of solar water heaters come from behind, but the South also has some well-known manufacturers of solar energy, and some have been developed over the past two decades, and now some manufacturers to enter the solar industry, solar manufacturers want to compete with the level of the North. At present, solar energy markets such as southern Guangdong, Guangxi is booming, huge potential, high consumption may be promoting it as the main battlefield of solar water heaters, research and design products for the South can be a great prospect.

Seasons with different solar water heater

Measure the performance of solar water heater is one of the merits of the thermal efficiency indicators, the so-called thermal efficiency is the per unit area within a certain period of time to absorb the energy and the ratio of global solar radiation. In particular, ambient temperature and solar water heaters, the greater the temperature difference, the more heat loss, the lower the thermal efficiency, so the measure of each quarter, the thermal efficiency are not the same. Thermal efficiency of the more stable, indicating the quality of solar water heaters more reliable.

Solar water heaters is the use of the sun to work, but overall several days each season to God \"face\", or overcast, or rain, rain, or foggy, not to mention the majority of the spring and summer precipitation, then we should borrow the auxiliary energy to meet the shortfall. At the same time, each season the Earth is not the same distance from the sun, at perihelion in summer and winter at aphelion. Perihelion when the solar radiation intensity is high, aphelion is relatively low, so under normal circumstances the heat capacity of solar water heaters in summer than in winter high.

Alternating seasons, orbits the Earth at a different location, the sun angle projected onto the surface of the Earth is not the same. Solar water heater collector surface and the angle of sunlight into the rays are not the same, and the vertical angle is the maximum thermal efficiency of solar water heaters, the best degree. However, the general solar water heater installation angle is fixed, which determines the water heater can not achieve the best efficiency of each season. Technical design of products generally consider high thermal efficiency in the winter because the winter temperature is low, and because at aphelion, this is conducive to the collector. At the same time, this design had a summer solar water heater hot water but not the phenomenon, but because the use of hot water in summer conditions are not harsh, this phenomenon is also no big problem.

Solar water heaters are long life and is closely related to seasonal changes in the environment. Under normal circumstances, air humidity, high temperatures, solar water heater stand, tank and so exposed to the air, over time, there will be corrosion and rusting. Winter is better, but the winter of pipe insulation is very important, especially pipe joints very demanding. Although the winter cold but also to bring some little trouble running their own, but once you have the right to use, does not prevent the user. Now many companies put forward a design standard for the winter, easy to use concept, as technology advances, the winter is not normal to use a big problem, the impact of solar water heaters by the season very much.
