In order to better reduce the consumption of coal, reasonably control environmental pollution and improve the air index, most regions in northern China have carried out the "coal to electricity" reconstruction project. With the continuous promotion of the "coal to electricity" reconstruction project, it will not be too difficult to find that the energy efficiency of ultra-low temperature heat pump products has become a key point that the bid inviter particularly cares about. Therefore, the air source heat pump cold and hot water unit company with a technical level on the low-temperature heat pump has become a familiar customer of "coal to electricity".
Energy efficiency is often critical because it immediately determines the cost of heating in winter. In addition to environmental pollution, traditional coal heating is only 80% less efficient, and the efficiency is slightly lower, so it is gradually replaced by new electric heaters, air energy heat pumps, and other methods. And electric heating, although it has eliminated environmental pollution, its energy consumption is too large. The efficiency ratio of 95% of the heating energy is equivalent to consuming 1kw of electromagnetic energy, which can only produce less than 1kw of energy. Therefore, if we want to use thermal storage electric heaters in a large-scale way in the "coal to electricity" project, it will take a long time to upgrade the ultra-low temperature air energy heat pump brand power grid, which not only increases the construction period but also poses a problem in terms of economic development pressure.
Compared with electric heating, the commercial ultra-low temperature air source heat pump with a higher heat efficiency ratio has obviously become a stronger choice of "coal to electricity". Air energy heat pump heating uses the basic principle of reverse Carnot to digest and absorb a lot of air energy water heaters, which are all machines and equipment. According to the work done by the refrigeration compressor, the air is compressed, causing high-temperature kinetic energy. The novel idea left behind the sunshade hat is that the energy efficiency ratio of electric heating is too low.
