Embodiment approach

[0134] According to a first embodiment of the present invention, a low-valley electric heat storage device is provided, the device comprising:

[0135] 1) The heat storage device box or shell 1,

[0136] 2) The central heat storage component, which includes: an upper water distributor 2, a lower water distributor 4, and an array of multiple heat storage elements 3 arranged between the upper water distributor 2 and the lower water distributor 4 or stacks,

[0137] 3) the first coil (such as a hot water coil) 5 surrounding the central heat storage component,

[0138] 4) an optional (ie optional) second coil (eg heating coil) 6 surrounding the periphery of the first coil (eg hot water coil) 5,

[0139] 5) an electric heating device 8 with an electric heating element 7 that heats the circulating water in the casing outside the heat storage device casing 1,

[0140] Wherein, the cold water inlet or tap water inlet 5a of the first coil (such as a hot water coil) 5 is located at t...

Embodiment 1

[0189] Phase change heat storage materials include the following components:

[0190]

[0191] Preparation process: heat and melt the component a), continue to heat up to 90°C, then add other components, stir and mix to form a phase-change heat storage material in the form of a mixture. The density (ρ) of the mixture is 2520kg / m 3 . Phase transition temperature range: 82-95°C. Latent heat of phase change (L) = 322-333kJ / kg. Specific heat capacity (Cp) = 5.52 kJ / kg·°C. The mixture was heated from 50°C to 90°C with a volume expansion rate of 0.05%.

[0192] Filling: Let the mixture cool to about 40°C, fill it into the tube-shaped or rod-shaped heat storage element (3), and weld the sealed port.

Description

technical field [0001] The invention relates to a low-valley electric energy storage heating device and a use method, which belong to the energy-saving and environment-friendly field of indoor heating, hot water supply and reduced use cost. Background technique [0002] In the process of heating indoors and providing hot water, where does the "heat source" come from and how to make good use of it is one of the key issues. For a long time, technicians in various industries have been continuously researching and considering from many aspects and perspectives. Various energies are fully utilized, some use wind energy, some use solar energy, each has its own advantages and disadvantages. The present invention utilizes low-peak electricity at night to store heat and use it during the day. The low-valley electric heat storage technology will be described below. [0003] CN203518237U discloses a high-density energy-storage electric heating domestic water device without a liner, wh...
