In northern my country, most of the winter heating season is heated by coal-fired boilers, so that the haze in winter is becoming increasingly serious, which brings a lot of troubles to the daily life of the majority of residents, and is more detrimental to the development of the green economy. With the country's attention to improving environmental issues, various policies and measures have been issued successively. Among them, the coal-to-electricity reform in 2016 has achieved remarkable results in improving the environment. Among them, air source heat pumps are clean heating equipment with good heating effect, energy saving and economy. They have been strongly supported by the country and are also welcomed by the masses. So why do air source heat pumps get the support of the country and the welcome of the masses?
The air source heat pump heating system is mainly composed of heat pump units, buffer water tanks, circulating water pumps and heating terminals. The system composition of different manufacturers is slightly different. Among them, the air source heat pump unit includes indoor and outdoor units. The main components are evaporators, compressors, condensers and expansion valves. Air source heat pumps work according to the "reverse Carnot" principle. Through the operation of the compressor system, it absorbs low-temperature heat in the air and then converts the heat into hot water. The specific process is: the compressor compresses the refrigerant, and the refrigerant with a higher temperature after compression passes through the condenser in the water tank to produce hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the heat of the air is absorbed by the evaporator and introduced into the refrigerant, and the refrigerant is then introduced into the water to produce hot water.
There are two types of hot water heating in the air source heat pump heating system: circulation heating and buffer water tank; there are three types of heating at the end: radiator heating, floor radiation heating, and radiator + floor radiation heating. Air source heat pump heating is a clean, environmentally friendly, and emission-reducing equipment. The later heating cost is 40% lower than that of electric heating and 60% lower than that of coal-fired boilers. The specific cost of air source heat pump heating is taken as an example in Beijing.
For users in rural areas of Beijing who use air source heat pump heating, peak and valley electricity prices are implemented. The daytime electricity price is 0.4883 yuan/kWh, and the electricity price from 9 pm to 6 am the next day is 0.1 yuan/kWh. The minimum heating cost per unit area is 12.5 yuan/m2, and the average is 20.2 yuan/m2. Taking a 120m2 residential building as an example, the minimum annual heating cost is 1,500 yuan, and the average annual heating cost is 2,424 yuan. The annual operating cost of a loose coal heating furnace is about 39.1 yuan/m2, and the annual operating cost of a gas wall-mounted boiler is about 34 yuan/m2.
In short, under the condition of ensuring good performance of the air source heat pump unit, its economic advantages are obvious.
Finally, for the coal-to-electricity transformation project, it is necessary to rationally choose the heating equipment that suits you, not blindly or follow the crowd. A warm and comfortable home starts with the purchase of an air source heat pump. Today, when the country advocates energy conservation and environmental protection and vigorously develops a circular economy, Leomon air source heat pump products have become the air source heat pump products of the majority of customers with their good product performance and excellent energy-saving effects. Leomon air source heat pump products have huge technical support and have frequently won the praise of customers in the fiercely competitive market.
