Problems solved by technology

The current water cold storage uses the sensible heat of the water temperature between 4-7°C for cold storage, but it has the disadvantages of low density, large volume of water, and easy mixing with cold water at different temperatures in the cold water tank.
Ordinary ice storage has the advantage of high density, but its refrigeration host must reduce the evaporation temperature by minus 6°C to minus 8°C to achieve (0°C) freezing, and it must be equipped with a dual-working condition refrigeration host, which increases the complexity and Increased power consumption

Abstract

The invention relates to an energy storage material, in particular to a phase change material for the cool storage of an air conditioner. The phase change material for the cool storage of the air conditioner in the invention is prepared from the following raw materials in part by weight: 55 to 65 parts of seawater or sea brine, 20 to 30 parts of NaSO4, 1 to 3 parts of aluminum reduced powder, 4 to 7 parts of thickening agent, 0.8 to 1.2 parts of NHCOOS, 0 to 5 parts of Na2B4O7.8H2O, 2 to 4 parts of H2O, 0.8 to 1.2 parts of CaO and 1 to 3 parts of H3BO3.H2O. The phase change material provided by the invention is a new material, is extensive in resources, low in cost and high in energy storage density, takes seawater resources as main resources, and compared with water of the same volume, is 3 to 5 times as great as the water in energy storage, thus the volume of stored ice and the cost can be reduced. Because a regulator and a supercooling preventing agent are added, supercooling and separating phenomena are avoided, the energy storage effect is improved, and the economical efficiency and practicability of the energy storage air conditioner are achieved. As total designed inverse-induction sets can be reduced, the cable investment, the power consumption and the pollution can be reduced, which is favorable for environment protection.

Description

Technical field: [0001] The invention relates to an energy storage material, in particular to a phase change material used for air-conditioning cold storage. Background technique: [0002] The energy storage air conditioner is designed to help the power grid to shift peaks and fill valleys, that is, the main unit of the air conditioner starts to cool water at night when the trough is low, and the cold water circulates in the water tank of the ice storage ball (board), so that the phase change material inside the ice ball (board) freezes, - At a temperature of 9°C, the main unit of the air conditioner operates under normal conditions during the ice making process, without adding other auxiliary equipment and consuming less power. The current water cold storage uses the sensible heat of the water temperature between 4-7°C for cold storage, but it has the disadvantages of low density, large volume of water, and easy mixing with cold water of different temperatures in the cold w...
