Solar water heaters are already familiar technology products, but new scientific and technological content of less and less, the solar water heater manufacturers to be invincible, top priority must be combined with the high-tech products, increase the necessary functions in order to improve its competitiveness, by Large profit margins, and guide the market.
Although solar water heater can really like color TV with remote control, as with auto manufacturers in Sheung Shui for minimal, mainly due to a few years ago, Sheung Shui for the automatic production but the quality of customs, the front of a few years, months, even on days Failure, to the users, manufacturers of solar water heater caused the trouble and losses. Therefore, the solar water heater manufacturers and dealers a bit "Tanhusebian", "once the snake bites, the fear Jingsheng 10 years", unless a last resort they will not install automatically for the Sheung Shui. Although the auto manufacturers in Sheung Shui for the well-intentioned remonstrations, the commitment years warranty, Baohuan and so on, but they still do not believe. When encountered strong demand installation of automatic controller users, but used to replace the water pipes of water temperature, the water level display instrument.Now many Fang Chanshang request entire floor, installed solar water heater, if used to monitor water pipes, due to the restrictions Tongqi Kong diameter, Hu Hu difficult to install, manufacturers have had to install water level, water temperature display instrument to replace the water pipes.Manufacturers from Sheung Shui for automatic promotion. as less than convenient, time-saving and water in the purpose of contradiction. Culprit is automatically Sheung Shui for a few years ago but the quality of customs, customs and quality but also the primary reason is: easy-scale sensors, leading to failure; electromagnetic valve to the water quality (sand, soil) the impact of work is not reliable; In addition, knowledge of weak electrical installers, the installation was not standardized, resulting in failure.
In fact, the solar water heater technology researchers have developed a scale not long the water level sensors, after nearly five years of tests, can solve this problem. Specific approach is: the sensor uses solid-silica heightening elements, rather than forming a metal-containing items (as we all know, pieces of metal guitar-scale), so that the sensor to achieve the objective of long life.
Electromagnetic valve of the manufacturers do not show weakness in the progress of the electromagnetic valve, the outlet-plus water treatment network, water filter mud, sand, iron filings and other impurities, in addition to improving the pads of the electrical performance has greatly improved, life can be 10 million (over 10 years). This increase in Sheung Shui for the automatic implementation of the components of the reliability and security.
If the solar manufacturers to bring to understand the technical installation of electrical workers, and gradually raise their level of physical and chemical installation and technical level, and to ensure accuracy in strict accordance with the Manual good signal to the line, while taking rain, the sun, will be able to resolve the current The existing problems.
Sensors reasons for the formation of scale and its control
At present, solar water heater is difficult to achieve automatic control the water level sensors in hot water easily in the long scale. 。 This time the water level sensors on the front of failure, failure, paralysis of the package of automatic control equipment, automation hinder the realization of solar water heaters. Therefore, improving the quality of solar water heater, solar water heater to increase the functions of the core issue is to solve the problem of scale sensor node.
At present, most of the water level sensors used metal parts, metal components is an important feature of Rezhanglengsu, Rezhanglengsu material changes in the macro-size larger, and its microscopic changes are: access to elements in the heat at the same time, by Large elements of the kinetic energy, while increasing the potential energy of the elements. Because of the increased potential energy, the two elements will take place between the displacement, when the two molecular scale larger than the distance between ions (calcium, magnesium ions) in diameter, the plasma will take advantage of scale, so many were As for the multi-scale Group molecules, thus forming the nucleus scale, when the scale nucleus formed, will scale ion polymer to scale nuclei, the rapid formation of scale. At the macro, the water temperature at 63 ℃ scale can be achieved over the medium to nuclei. Evidently, metal, plastic, glass, stone and so can not be the ideal water level sensor material.
Because of plastic-like material between the material and is entirely different order, it is very difficult acquisition of a nucleus, not easy guitar scale, can be a more satisfactory level sensor. If the plastic-like material to add anti-scaling of high-molecular materials, to achieve the desired anti-fouling purposes.
Virtually eliminating scale, can also tap into the tank before the installation of special filters, the filter is the use of nano-materials technology manufacturing. In this way, first into the water and purified water was heated to achieve the objective of eliminating scale. However, this approach its high cost, frequent cleaning and replacement filters are more ordinary users are not acceptable, so the programme could not be promotional.
To sum up, universal good contact water level sensors, to achieve Anti-scale, not the purpose of failures, must be the type of plastic sensor. Only then can we achieve long life and easy to popularize, promote it so that the solar water heater control to achieve the objective of worry-free.
Solar water heaters, which features more appropriate to increase »
Solar water heaters with the construction of small towns, growing market, but also stimulating additional features of its matching accessories market. Sheung Shui, as automatic, electric heating help, antifreeze detection, emptying devices, etc., for the development of energy the sun has played the role can not be ignored, but also a lot of problems.
Sheung Shui is automatically make people's life convenience and saving water, energy, peace of mind, the significance is great. Sheung Shui automatically for the life of the ordinary life of a decision by the sensor. The general contact sensors and non-contact, contact common good, easy and water heaters, matching the price for promoting universal.Solar water heaters because the water temperature high, the water of calcium and magnesium ions can easily scale to create the conditions nuclei, so that contact with metal sensor easily scaling, malfunctioning sensors, automation, Sheung Shui for the loss of great significance.。 Some solar dealers have paid a price for this, despite the requirements of users with automatic Sheung Shui, dealers are reluctant to give users the installation of automatic-Sheung Shui. If we can solve the water sensor end of the scale and corrosion problems, automatic Sheung Shui for the normal life will be several times the increase, dealers can dare to meet the requirements of users, both water-saving and convenient. Therefore, the universal is a matter of time before. Intelligent solar water heater is advancing with the requirements of the trend of the times.Effective measures are: do not use an e-scaling of metal and plastic sensors, and the use of hard plastic like scaling the sensor, a symmetrical exchange signals in the anti-corrosion control of electrical power.
to resolve the 24-hour hot water supply has played a certain role, the South is so wet areas. However, electric heating, there are many outstanding issues. Electric heating costs are great, according to the asymmetry principle of thermal conductivity, temperature is time to cool down the number of times the power consumption is great. 200 liters of water temperature 30 ℃, excluding the case of heat loss electric heating power consumption required to seven degrees. Electric heating is a security problem must attach great importance to the event, many manufacturers increase the security protection plugs (leakage protection), but security protection plugs in a reliable ground under the conditions of use. The reality is that although the majority of the three outlets, but not ground-grounded. Once the electric heater leakage, security protection such as the hypothetical, the consequences would be unthinkable. Although some products marked "a bath, electricity," but there Manbuzaihu users, ignorance of children is more cynical. To really solve this problem, water is an effective and reliable way to ground, but ground water is very difficult. Leakage issue has always been a major threat. So do not have electric heating equipment frequently used hot water, can take more thickening vacuum tube, increasing water tank insulation layer approach, or the installation of solar water heater separated.
