Wind energy, heat energy, solar energy, nuclear energy, hydrogen energy, geothermal energy. Are you familiar with all the clean energy which including air energy?
Air energy, the low-grade heat energy contained in the air, is the air energy (source) heat pump to collect and utilize the air energy. In 2009, the EU formally incorporated air source heat pump into renewable energy technology.
The benefit of air source heat pump is its energy saving and environmental protection. According to the public data, its thermal efficiency can reach 400% - 600%, and its use cost is equivalent to about 25% of the electric water heater. At the same time, the energy-saving efficiency of air source heat pump is much higher than that of the traditional electric auxiliary heat mode, and it has a great market space in the South under the high average ambient temp conditions.
Because the industry generally agrees that the ambient temperature of the air source heat pump is maintained at - 5 C to above 0 C, and the ideal effect of the air source heat pump below 40 C is almost the same as that of the suspect. That is to say, the efficiency of air source heat pump will be greatly reduced under the northern winter low ambient temperature conditions, which limits its market expansion to a certain extent in theory.
However, the market demand has made subtle changes in the North-South situation of air source heat pump. As a matter of fact, up to now, the market demand of the North is obviously better than that of the South. The great driving force behind this is the imminent cleanliness of winter heating in the north, and the improvement of atmospheric environment has given an ultimatum to the traditional heating methods such as bulk coal heating.
