Which brand of solar water heater is best?

There are many brands of solar water heaters, such as Huangming, Sanle, Temple, Tsinghua Sunshine, Aucma, etc. The recommendations are as follows:

1. Huangming: Huangming Solar Co., Ltd. (hereinafter referred to as "Huangming Solar"), as a leader in the global solar energy industry, promotes a collector area of ​​3 million square meters per year, which is equivalent to the entire solar energy industry. European Union and more than double that of North America. The business mainly includes: solar water heaters, high temperature solar thermal power generation, solar air conditioners, sea water desalination, etc.

2. Sanle: Shandong Sanle Solar Energy Co., Ltd. was founded in 1987, with Shandong Academy of Sciences as technical support. It is a high-tech joint stock enterprise located in Jinan City. become a national research and development companyement and production. An integrated, large-scale, specialized solar power generation company. Currently, he is the vice president of the China Solar Energy Industry Alliance and the president of the Shandong Solar Energy Society.

3. Temple: Temple began operations in 1989 and is committed to becoming a trusted, comprehensive provider of new energy services globally. In more than 20 years of development, it has always been at the forefront of industrial development, from inventing the first round solar water tank and redefining the appearance of solar water heaters to the first development of the Ф 58, which today represents more than 80% of the market. Vacuum tubes, etc.

4. Tsinghua Sunshine: Beijing Tsinghua Sunshine Energy takes solar energy utilization technology as the core and integrates product research and development, manufacturing, engineering design and marketing,and engages in the promotion and application of clean energy. Tsinghua Sunshine Company has built the world's first automated collector tube production line and the world's largest all-glass vacuum collector tube production base, with an annual production capacity of 12 million collector tubes and 300,000 water heater.

5. Aucma: Aucma adheres to the strategic goal of becoming the world's most reliable refrigeration equipment supplier and "refrigeration expert", constantly promotes technological innovation, and has formed a core business of freezers, refrigerators and of commercial products. cold chain products. The main business focuses on ultra-low temperature equipment, electric bicycles, washing machines, household appliances and vending machines as the development activity, and electric tool carts at ournew energy and new energy household appliances as future business.

Detailed information:

< p>Solar water heater selection method:

1. Among thermal performance indicators, the higher the “average daily efficiency” the better and the “average heat loss coefficient” “The lower the better.

2. The key part of the domestic solar water heater is the all-glass vacuum solar collector tube (called vacuum tube). The quality of the vacuum tube directly affects the performance of the whole house. solar

3. The design of the support of domestic solar water heaters should be reasonable and should have sufficient strength, rigidity and corrosion resistance to ensure sufficient long-term carrying capacity. Buy Home Solar EnergyLoWhen installing a water heater, be careful not to focus solely on the appearance of the support.

4. Reflectors for domestic solar water heaters are very important and come in various shapes, including flat reflectors, curved reflectors, embossed aluminum, etc.

5. It is very important to choose the insulation layer of domestic solar water heaters. Polyurethane foam is generally used, but polyurethane is divided into several grades and their quality varies greatly.

Basically, hydrogen is not the main form of energy in modern society, and there are not many opportunities to use it. When the cost is high, few people naturally use hydropower alone. On the one hand, the electricity transmission method is relatively mature and inexpensive. On the other hand, hydroelectric plants have energy storage measures plPeak efficient: When power consumption is low, simply use the remaining electricity to pump water. But this does not mean that the production of hydrogen by electrolysis of water has no applications. Occasion: As a substance with the same energy density as oil, it can be used as a clean energy source to replace oil in places where electricity is not suitable, e.g. like rockets, planes, ships, etc. ; in addition, as an intermediate substance for energy storage, wind energy and photovoltaic energy can be used. Water electrolysis produces hydrogen, which is then used to generate electricity through a gas turbine, which can effectively solve the problem of integrating a new energy network. The problem with liquid hydrogen is that there is currently no specific storage methodeffectively and safely. Large-scale storage still relies on low temperature and high pressure, which is not only expensive, but also dangerous. Its use is acceptable in rocket engines, but not for civil and commercial use. As a solution, solid-state metal hydride storage has many beautiful dreams and various cruel realities. It still belongs to the category of rare metals, and it is far from possible to safely and efficiently store it in the future, as well as wind energy. photovoltaic and electrical energy provided by nuclear energy have declined considerably, and it is quite possible that hydrogen energy will replace oil energy in some regions.
