AI Technical Summary

⚠Technical Problem

High energy consumption and resource waste caused by power grid load fluctuations, especially the uneven energy consumption of air conditioning systems during peak and off-peak periods, affect the operating efficiency and cost of the power system.

⚗Method used

The system utilizes a solid-state energy storage module to store energy by heating magnesium-zirconium alloy through trough electric heating. The circulating gas is then heated via a heat exchange module to drive hot water circulation. Combined with a switching three-way valve and control module, it enables flexible switching between heating and cooling modes. The stored thermal energy is used to drive the air conditioning system, replacing the traditional electric compressor.

🎯Benefits of technology

It reduces the operating electricity cost of air conditioning units, improves the flexibility and efficiency of the system, reduces the high energy consumption and maintenance costs of compressors, and achieves optimized utilization of power resources.

Abstract

This invention discloses a solid-state energy storage air conditioning unit with dual-mode heating and cooling, belonging to the field of air conditioning technology. It includes an energy storage module that uses off-peak electricity to heat a magnesium-zirconium alloy for thermal energy storage; a heat exchange module that uses the heated magnesium-zirconium alloy to heat circulating gas, which in turn heats water in a steam circulation pipeline; and a control module that controls a first and a second switching three-way valve to synchronously switch between each other. In heating mode, the heating circulation loop is activated; in cooling mode, the cooling drive circulation loop is activated. Based on monitoring data from sensor components in each pipeline, the module controls the operation of the circulating fan between the energy storage module and the heat exchange module, as well as the pumps and valves in each pipeline. By incorporating an energy storage module and utilizing off-peak hours for thermal energy storage, this invention significantly reduces the operating electricity costs of the air conditioning unit during peak daytime hours, bringing substantial economic benefits to users.
