The system is composed of the energy storage process and the energy release process, which stores the off-peak electric energy and supplies the cooling, heating and power at the peak time. During the energy storage process, the ambient air (A1) is pressurized by the compressors (COM1 to COM5) driven by the off-peak electricity.
