What Role does Air Source Heat Pump Play in "Coal to Electricity"?

The "coal to electricity" clean energy heating transformation project is implemented in northern China, mainly to improve the quality of air, reduce the frequency of fog caused by winter heating, improve the quality of life of residents, and contribute to the sustainable development strategic plan. What role does air source heat pump play in "coal to electricity"?

1. Improve air quality and reduce the frequency of fog.

Air pollution is mainly caused by industrial pollution, automobile exhaust, coal combustion, etc.; in the winter heating season in the north, the pollution caused by using coal-fired boilers for heating should not be underestimated. The burning of scattered coal has not been cleaned, so the pollution is the greatest. The emission of one ton of scattered coal is equivalent to the pollutants emitted by 5-10 tons of power plants. After "coal to electricity", the quality of air has been significantly improved. In 2017, a total of 27.7 billion kWh of electricity was replaced, 27.62 million tons of carbon dioxide emissions were reduced, and 8.78 million tons of sulfur dioxide, nitrogen oxides and dust pollutants were reduced.

2. Improve the quality of life of the people.

In winter, coal-fired boilers are used for heating. Whether it is day or night, coal and coal slag must be frequently added. The most important thing is that people are needed to watch over it, for fear that the stove will go out. It wastes manpower and material resources, and the temperature fluctuates. After the "coal to electricity" policy, many people installed air source heat pumps, which can be controlled by intelligent remote control and can maintain a comfortable temperature for 24 hours with one-button setting. It is more convenient than burning coal, and the comfort is incomparable. In addition, the government has electricity price subsidies for "coal to electricity" families, and they can enjoy low electricity prices at night. After a heating season, the cost is not much higher than that of coal heating. It is really a convenient and beneficial policy.

3. Enhance the sense of security of the people

People are prone to carbon monoxide poisoning accidents when burning coal for heating, and they can't sleep well at night. Because many people are sent to the hospital for emergency treatment every year for using coal, gas, and electric heating, they are terrified to use them. It is better to use air source heat pumps for comfort and peace of mind. Air source heat pumps do not require gas and do not emit harmful gases; the unit has water and electricity separated, and there is no risk of leakage and injury, which greatly enhances the sense of security of the people.

4. Energy saving and environmental protection

Air source heat pumps are a kind of equipment that uses pipes to absorb low-grade heat energy in outdoor air, compresses these low-grade heat pumps into high-grade heat energy, and then uses these high-grade heat energy to heat cold water, and finally produces a large amount of hot water for domestic hot water and heating. Because it mainly uses free heat in the air for heating, the heating efficiency of air source heat pumps is as high as 400%, which is 4 times that of ordinary electric water heaters. According to statistics, it only takes 11 degrees of electricity to heat one ton of tap water with an air source heat pump to a temperature that can be used for bathing.

5. Long service life

Electric water heaters must be replaced after 10 years of use, and solar water heaters are exposed to wind and rain all year round, and their operation and use are unstable. The design life of air source heat pumps is generally 15 years, and some even reach 20 years. Moreover, as the technology of air source heat pumps continues to mature, the warranty period provided by manufacturers is getting longer and longer, bringing more protection to users.

With the emergence of air source heat pumps, not only has the quality of air been improved, the frequent occurrence of fog caused by winter heating has been reduced, and the quality of life of the people has been improved. It is efficient, stable and safer. From a long-term perspective, the use of air source heat pumps is an investment in the future. To improve the quality of life, we must first start with winter heating, summer cooling, and 24-hour uninterrupted domestic hot water throughout the year.
