Problems solved by technology

[0002] At present, water geothermal or electric geothermal are basically pouring concrete, using concrete as the heat storage material of geothermal heat, but the heat storage capacity of concrete is limited, when the heating is stopped, the floor, furniture and walls of the room will release heat to the room
Not durable due to limited heat storage capacity
In addition, at present, the development of special heat storage and cold storage products for water geothermal or electric geothermal is relatively slow
This phenomenon is a waste of energy to a certain extent

Abstract

The invention discloses a low temperature step phase change heat storage and cold storage device which comprises black plastic pipe bodies and a long fixing plate. The two ends of each black plastic pipe body are fixed or directly bonded to the long fixing plate respectively. A material A or a material B is arranged inside the black plastic pipe bodies, the black plastic pipe bodies which are adjacent to the black plastic pipe bodies with the material A are all provided with the material B, and the black plastic tube bodies which are adjacent to the black plastic tube bodies with the material B are all provided with the material A. The material A is composed of 80%-84% of Na2SO4 10H2O, 1%-3% of borax, 1%-2% of sodium carboxymethyl cellulose, 3%-6% of white carbon black, 2%-4% of NaCl, and 0.5%-1% of sodium hexametaphosphate. The material B is composed of 80%-94% of CaC12H2O, 1%-3% of barium hydroxide, 0.5%-2% of NaCl, 0.5%-2% of sepiolite, and 0.5%-2% of sodium silicate. The low temperature step phase change heat storage and cold storage device prolongs heat storage and heat releasing time, and achieves the effect of saving energy.

Description

technical field [0001] The invention relates to a heat storage device, in particular to a low-temperature stepped phase change heat storage and cold storage device. Background technique [0002] At present, water geothermal or electric geothermal are basically pouring concrete, using concrete as the heat storage material for geothermal heat, but the heat storage capacity of concrete is limited. When the heating is stopped, the floor, furniture and walls of the room will release heat to the room. Due to the limited heat storage capacity, it cannot last long. In addition, the current development of specialized heat storage and cold storage products for water geothermal or electric geothermal is relatively slow. This phenomenon is to cause a certain degree of energy waste. Contents of the invention [0003] Aiming at this situation, the present invention is a low-temperature stepped phase change heat storage and cold storage device. When the water geothermal or electric ge...
