【概要描述】my country's north, northeast and northwest regions all need heating in winter, and southern regions such as Jiangsu and Hubei also have greater heating needs. According to statistics, about 100 million households in rural towns and cities in the three major regions do not have a central heating network. Rural houses are generally brick-concrete structures with no insulation on the outer walls. In winter, the indoor temperature should be kept above 15°, and the average household consumes 4.36 tons of standard coal in each heating season. If solar energy is used, 100 million households will save 436 million tons of coal and reduce carbon dioxide emissions by 1.13 billion tons.

my country's north, northeast and northwest regions all need heating in winter, and southern regions such as Jiangsu and Hubei also have greater heating needs. According to statistics, about 100 million households in rural towns and cities in the three major regions do not have a central heating network. Rural houses are generally brick-concrete structures with no insulation on the outer walls. In winter, the indoor temperature should be kept above 15°, and the average household consumes 4.36 tons of standard coal in each heating season. If solar energy is used, 100 million households will save 436 million tons of coal and reduce carbon dioxide emissions by 1.13 billion tons.

Taking Hebei as an example, in Shijiazhuang, Langfang, Gu'an and other regions of Hebei Province, some enterprises have built many demonstration projects of solar heating for farm houses. Complementary systems have achieved better results.

Therefore, in the face of the huge potential demand for heating in winter by users in villages and towns in my country, solar heating has a broad market space. Among them, single-family installation is easy to implement, and the village and town comprehensive system project is relatively large, but it is more convenient to realize intelligent management after completion, and the energy saving effect is also greater.

Solar heating refers to the conversion of scattered solar energy into hot water heat energy through thermal collectors (flat solar collectors, vacuum solar tubes, solar heat pipes, etc.) ), provide the building's winter heating needs, we call it a solar heating system, or solar heating for short.

There are many types of solar heating. According to the different ways of using solar energy, the structure of solar collectors, the structure of hot water storage tanks, the types of auxiliary energy, and the types and types of end radiators, solar heating can have Various combinations.

According to the solar energy utilization method, it is divided into active type and passive type; according to the use medium, it is divided into liquid solar heating system and air solar heating system; according to the heat storage period, it is divided into daily energy storage, weekly energy storage and cross-season energy storage solar heating system; According to the combination of heat collection system and heat storage system, it can be divided into open collector with open water tank, open collector with closed water tank, and closed collector with open water tank. It can be divided into solar heating/air conditioning integrated system, solar heating/hot water combination system, solar heating/air conditioning/hot water combination according to the comprehensive utilization with other systems According to the type of end heat dissipation components, it is divided into ground radiant heating system, ceiling radiant heating system, fan-panel heating system, wall coil radiator system, various forms of radiator radiator system, etc.

Using solar energy for heating, clean, safe and energy saving. Solar heating is different from ordinary heating methods. Traditional heating uses coal, electricity, oil, and gas. The solar heating system project is installed, and hot water can be obtained while heating, and cooling can be realized, forming a solar "triple supply" integrating heating, cooling and hot water. Although the initial investment of solar heating projects is relatively large, the system life span is 15-20 years, and the project payback period is 6-7 years compared with coal-fired, 3-4 years compared with natural gas, and 1-2 years compared with electric heating . Therefore, the economic benefits of solar heating are very good. The various advantages of solar heating determine that it can replace other energy sources in residential, commercial and industrial and agricultural heating applications.

The solar heating control module of Jiangsu Huilifeng Intelligent Control Technology Co., Ltd. has the functions of automatic water replenishment, automatic water return, solar heat collection cycle, automatic heating with electric auxiliary heat, emptying, and antifreeze and heat tracing. At the same time, the control function has timing settings: there are 4 sets of timing functions for water replenishment, return water, and electric auxiliary heat, and the start and stop time of this function can be set. Another separately designed timer can be used for other time control such as water supply and drainage. Antifreeze heat tracing operates automatically according to temperature changes. It is suitable for hot water supply system and heating system. It can be matched with air energy heating system, electric heating system, solar heating system, air energy + solar heating system, and can also be used for solar heating system in the north. , cost-effective products
