Description

technical field

[0001] The invention relates to the technical field of water heaters, in particular to a phase change energy storage water heater. Background technique

[0002] The phase change energy storage water heater utilizes the advantages of high enthalpy value and high energy storage density of the phase change energy storage material to store electric energy or thermal energy in the phase change material of the phase change energy storage water heater, and use tap water to pass through the heat exchange plate when hot water is needed The tube displaces the heat stored in the phase change material. The high enthalpy value of phase change materials determines that phase change energy storage water heaters have many advantages. Compared with existing water storage water heaters, this water heater has a smaller structure, less internal water storage, no stagnant water, and can prevent scaling. occurs, electric heating of phase change materials can achieve electricity-w...
