What is air energy?

Air energy is a low-grade energy that exists widely, is given equally and can be used freely. It uses heat pump circulation to improve its energy grade and then uses it to heat domestic hot water. Because one part of the electric energy can absorb 3 parts Air energy can be used to supply 4 parts of heat energy to heat the hot water system. Therefore, it is an energy-saving and environmentally friendly new technology with great potential for development and application, and is of great practical value.

In recent times, a new product called "air energy water heater", which is called the 5th generation water heater, has been widely hyped in major media, boasting an energy saving of more than 70%, which is really extraordinary. ability.

The high energy efficiency and economic and social value of "air energy water heaters" have been widely publicized and reported in major newspapers, the Internet and other media. The report claimed that "air-source water heaters will replace gas and electric water heaters in the near future," and claimed that "the popularization and use of air-source water heaters will save a Three Gorges Power Station."

According to reports: air-energy water heaters use the principle of the reverse Carnot cycle. Driven by electrical energy, the compressor does work, causing the heat-absorbing working medium to undergo a physical cycle phase change, and uses the heat exchanger to absorb heat and It is the process of releasing heat that heats up cold water to produce hot water. But how much power is really consumed? How much heat energy is absorbed from the air? Are you really saving so much? Whether air-source water heaters are really so energy-saving remains to be studied
