In some cities, the electric power consumption of the electric water heater accounts for 20-40% of the total household energy consumption. The electricity consumption of China continental residents in 2020 is estimated to be 14576 hundred million kW.h, which is 20.33% of the total electricity consumption. The rapid increase of the consumption of the domestic electric power of residents will intensify the energy and environmental stress of China.
Most of the electricity consumption of the traditional electric water heater belongs to a water storage type electric water heater, and the heat is wasted due to the conduction and heat consumption of the wall of a heat-insulation water storage barrel.
Specifically, the calculation method of the heat consumption Q of the wall of the heat-preservation water storage barrel is as follows: q is F.K (T-T)

δ1The thickness of the material of the outer wall of the water storage barrel is mm;
δ2the thickness of the heat insulating material of the water storage barrel is mm;
δ3the thickness of the material of the inner wall of the water storage barrel is mm;
λ1-thermal conductivity coefficient W/m of outer wall material of water storage barrel2℃;
λ2-thermal conductivity of heat insulating material of water storage tank W/m2℃;
λ3-heat conductivity coefficient W/m of inner wall material of water storage barrel2℃;
In general a1≈8.7~11.6W/m2℃;a2≈3500W/m2℃;
δ1The thickness of the outer wall material of the water storage barrel is usually made of 0.8mm carbon steel plates;
δ2the thickness of the heat insulating material of the water storage barrel is usually made of polyurethane foam plastics and is 25 mm;
δ3the thickness of the inner wall material of the water storage barrel is made of an enamel protective carbon steel plate, and the thickness is usually 0.8 mm;
λ1the thermal conductivity coefficient of the material of the outer wall of the water storage barrel is 48.5W/m2℃;
λ2Barrel partition of water storage barrelThe thermal conductivity coefficient of the thermal material is 0.02W/m2℃;
λ3The heat conductivity coefficient of the inner wall material of the water storage barrel is 17W/m2℃;
Taking a certain brand product in China as an example, the external dimension of 80 liters of capacity is,863mm in length, the heat transfer area of the wall of the heat-preservation water storage barrel to the environment is as follows:
463mm×π×863mm+(π(463mm/2)2×2)
=1592016.8mm2
=1.5920168m2
heat transfer coefficient:
the wall of the heat-preservation water storage barrel consumes heat:
Q=F.K(T-t)
in the formula: f-area m of wall of heat-preservation water storage barrel2;=1.42351m2
K-barrel wall heat transfer coefficient K of water storage barrel is 0.74822W/m2℃(0.6434692kcal/W/m2℃)
T is the temperature of hot water in the barrel is 65 ℃ (most of the existing household electric water heaters are marked as the upper limit temperature of 70 ℃, and 65 ℃);
t is 20 ℃ of the environment outside the barrel (the indoor temperature in winter in the north is 18-23 ℃ due to the existence of heating conditions, and the indoor temperature in winter in south is 5-12 ℃ when 20 ℃ is taken out due to the absence of heating facilities);
the heat consumption of the wall of the heat-preservation water storage barrel is as follows:
Q=0.6434692kcal/m2·h·℃×1.5920168m2(65℃-20℃)=46.099kcal/h

In addition, the existing electric water heater adopts a tubular electric heating element as a water heating electric heating pipe, and consists of a stainless steel outer pipe, a spiral resistance wire and insulating material crystallized magnesia powder.
The high-temperature resistance wires are uniformly distributed in the stainless steel pipe and are positioned in the center of the stainless steel pipe, the gap part is filled with crystallized magnesium oxide powder with good insulating property, when current flows in the high-temperature resistance wires, the generated heat is diffused to the surface of the metal pipe through the magnesium oxide powder, the surface of the metal pipe is diffused for temperature rise, then the surface of the metal pipe forms high temperature, and the high temperature is transferred to the low-temperature water side, so that the aim of heating water is fulfilled.
The higher the temperature of the resistance wire, the higher the efficiency of conduction to the stainless steel tube through the crystalline magnesia powder, but the higher the temperature of the resistance wire, the more prominent the carbonization tendency of the crystalline magnesia powder, and the insulating property of the crystalline magnesia powder is lost when the crystalline magnesia powder is completely carbonized. The heat generated by the resistance wire can be transferred to the water to be heated through the heat resistance of the magnesium oxide and the stainless steel tube shell, and the multi-layer heat resistance is the main reason of low heat efficiency of the electric heating tube heater.
