1. Introduction Heating, ventilation and air conditioning systems play a significant role in ensuring human thermal comfort and are among the largest energy consumers of the building sector (Vakiloroaya et al., 2014) which consumed 20–40% of total energy use in developed countries (Pérez-Lombard et al., 2008).).
For the power consumption of 0.5 W, the average temperature of the hottest cell with the liquid cooling system is around 3 C lower than the air cooling system. For 13.5 °C increase in the average temperature of the hottest cell, the ratio of power consumption is around PR = 860 .

Liquid air energy storage (LAES) is an emerging technology where electricity is stored in the form of liquid air at cryogenic temperature. The concept of using liquid air for electric energy storage was first proposed in 1977 [9]. Several years later, several companies actively carried out research on LAES technology in Japan, such as ...
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.
