With the frequent occurrence of haze across the country in recent years, replacing coal with electricity has become a heating development trend in the north. Paying attention to the development and utilization of low-carbon energy, how to effectively use cleaner energy will be the key to solving energy and environmental protection problems. important means. Conventional solar heating systems are susceptible to climate effects. Cannot run all day. The popular air source heat pump in recent years is a high-efficiency energy-saving device. It can be combined with a solar heating system to make up for the lack of solar heating.
Compared with a single hot and cold source system, the air source heat pump and solar combined heating system can realize the complementary advantages of solar energy and air energy. solar collector uses seasonal heat storage in hot water storage tanks to reduce the operating time of air source heat pump units in winter and save energy. The heat storage function of the air source heat pump unit in the hot water storage tank on cloudy days ensures the user's heating needs all year round.
Moreover, air source heat pumps can absorb heat from the air, greatly reducing the size of solar collectors and hot water storage tanks, and reducing the initial investment cost of solar collectors. The use of solar collectors increases the heat exchange efficiency of air source heat pumps and solves the problem that air source heat pumps are prone to frost in low-temperature environments. The organic combination of the two allows the strategy of replacing coal with electricity to proceed smoothly.
Analysis of the composition of solar + air source heat pump heating system
Air source heat pump introduction:
Air source heat pump is a type of heat pump technology and has the reputation of "porter of nature's energy". It has multiple advantages such as low cost of use, easy operation, good heating effect, safety and cleanliness. The air source heat pump uses the energy in the air as the main power, and uses a small amount of electrical energy to drive the operation of the compressor to achieve energy transfer. It does not require complex configuration, expensive water intake, recharge or soil heat exchange systems and machine rooms, and can gradually reduce Traditional heating brings a large amount of pollutant emissions to the atmospheric environment, ensuring the heating effect while achieving the purpose of energy conservation and environmental protection.

Solar heating system introduction:
Solar heating generally consists of solar collectors, hot water storage tanks , connecting pipes, auxiliary heat sources, cooling components and control systems.
Solar heating system control cabinet introduction:
1. control cabinet surface treatment: The solar heating system control cabinet uses a thickened base box, which is anti-corrosion and rust-proof;
2. Touch screen controller: The heating system is controlled through the main control module Intelligent management and control, the control cabinet has a touch screen controller, which can realize the centralized integration of various functions such as solar thermal collection , constant temperature water supply, and compensation heating on the same working platform, as well as a complete set of fault warning, data storage, energy consumption analysis, energy efficiency analysis, etc. Integrated operation and maintenance management and control of thermal systems.
3. Solar heating module: The solar heating control module has the functions of automatic water replenishment, automatic water return, solar heat collection cycle, automatic electric auxiliary heating, emptying, and anti-freeze heating. At the same time, the control functions have timing settings: water replenishment, water return, electric auxiliary heating, has 4 sets of timing functions, and the start and stop time of this function can be set. A separately designed timer can be used for water supply, drainage and other time controls. Anti-freeze heating runs automatically according to temperature changes.
Huilifeng Intelligent Control Solar Heating Module Function Introduction:
Temperature difference cycle: The heating cycle uses a temperature difference cycle, which is applicable to both direct and indirect heat exchange methods.
system anti-freeze: is mainly aimed at the cold weather in the north. This function can recycle hot water in the solar coke heater to reduce heat loss and at the same time recycle the hot water in the header , vacuum tube and pipeline to the water tank to achieve drainage. Empty state to achieve antifreeze effect.
Electric auxiliary heating: Solar energy + multi-energy complement each other, when the sun's illumination is insufficient or the weather is continuous.The heat of the solar energy is not enough for heating, and the system will automatically control the start and stop of the auxiliary heat source.
Heat tracing function: automatically starts the heating tape for heating by detecting changes in temperature to avoid pipeline freezing under low temperature conditions.
Intelligent heating: The system automatically runs the heating cycle according to the temperature in the room during the heating period. It automatically stops when the temperature reaches the temperature and starts again after the temperature drops, ensuring the continuity and comfort of the heating while being more energy-saving. .
The anti-explosion pipe intelligently fills the water according to the temperature of the sun. The water will not be filled when there is no sun. It is also equipped with anti-explosion pipe protection, so the intelligent water supply will not explode the pipe.
As a renewable energy source, solar energy has received a lot of attention in recent years. It is low-cost, clean and environmentally friendly, does not produce pollutants during use, and is inexhaustible. my country's solar energy resources are very abundant, with an average daily The amount of radiation can reach 4kw/m2, and the annual sunshine hours are more than 2000h. At present, the field where most solar energy is used in our country is solar water heating system. If solar energy is applied to residential heating, it can not only solve the tight oil and electricity supply, but also reduce fossil energy. consumption, alleviating the pressure of energy crisis on today's society, and also contributing to environmental protection and improving the human living environment, which has certain social and economic benefits.
