In simple terms, the principle of air energy saving is simply using a small amount of electricity to transfer heat from the air to heat water, unlike water heaters electric heaters that directly use electric heating resistors to boil water. The heat of the air costs nothing. One of the expenses is the money needed to hire a professional porter (to buy air power), and the other is the money needed to buy food from the porter (the electricity bill) .
People hope that the air can be used without electricity, because solar energy can directly heat water through the sun. However, during rainy winters, when there is no sun and hot water is not enough, so does solar energy. must use electricity to help with heating. Air heat is low quality thermal energy and the temperature does notst not high enough to directly heat the water enough for a shower. Therefore, electricity is required to operate the compressor, pressurize and heat the heat absorbed by the air, and then transfer it to the water.
