In the middle of last month, at the publicity and implementation meeting of the â€œGuiding Opinions of the Ministry of Industry and Information Technology on Promoting the Healthy Development of the Solar Water Heater Industryâ€ jointly organized by the Ministry of Industry and Information Technology and the Household Electrical Appliances Association, Gao Yanmin, Deputy Director of the Consumer Products Department of the Ministry of Industry and Information Technology, proposed that at present, solar thermal utilization in China The most mature industry is solar water heaters, but the solar water heater industry is facing rapid development, but also faces a series of prominent problems such as product homogenization and hot water supply.
Since the start of the solar water heater industry in 1993, after more than 20 years of development, solar water heaters have made great progress, but there are also some problems. On the one hand, the solar water heater market faces the phenomenon of product homogenization caused by the lag of technology upgrade and slow product update; on the other hand, the solar water heaters that users have generally reflected for many years are severely restricted by weather conditions and cannot meet the 24-hour hot water bath throughout the year. The demand has not been resolved. The breakthrough of this bottleneck also requires the industry to inject new ideas and new technologies.
In recent years, the complementary use of solar energy and heat pump, gas, electricity, biomass and other energy sources has been gradually promoted, and â€œenergy integrationâ€ has become a key word for the development of solar thermal utilization industry. Li Dexiang, a member of the China Green Building and Energy Conservation Committee, also said that multi-energy utilization is the direction of the development of the solar water heater industry. Multiple energy sources can complement each other and are not restricted by the sun, satisfying consumers' 24-hour energy demand.
The reporter learned that at present, Haier has developed a dual-energy solar water heater with multiple energy sources. Haier dual-heat solar water heater is a multi-energy water heater with solar energy and complementary energy. It has an intelligent monitoring system that can monitor solar water temperature and water level at all times. When solar heating cannot meet the expected temperature requirements, dual-heat solar energy will automatically switch to Electric heating mode to ensure hot water supply. In addition, consumers can easily complete the hot water switching between solar water heaters and electric water heaters through a knob during bathing, achieving double-channel water supply, and saving more than 80% of electricity throughout the year. It is understood that Haier double thermal solar water heater will be listed and sold in Jingdong Mall recently.
Along with the country's emphasis on renewable energy applications, various forms of energy applications are frequent, and one of the most important trends is â€œcomplementary from single energy to multiple energy sourcesâ€. Nowadays, the complementary use of multiple energy sources has become a development trend. The multi-energy combination can not only achieve the goal of energy saving and emission reduction, but also make up for each other's defects between different energy sources, and improve the green and comfortable living quality of residents through rational allocation of energy.
