Traditional air conditioning (AC) faces low energy efficiency and thermal comfort challenges. This study explores the integration of thermal energy storage (TES) containing a phase change material (PCM) with a conventional AC unit (PCM-AC) to meet the challenge.
The LHTES can be used as thermal storage to store the thermal energy from the solar or waste energy systems that would be used as an energy resource for the absorption air conditioning or desiccant cooling technologies.
A new direction for utilization of energy storage technologies is given. Due to higher energy consumption for application of chilled energy storage technology in air-conditioning system in China, this paper provides two new air-conditioning systems

Abstract Phase change material (PCM)-based cold energy storage systems (CESS) offer a promising solution for improving energy efficiency and cost-effectiveness in air conditioning systems. However, their limited heat transfer efficiency hinders widespread adoption.
This review introduced the air condition with cold storage devices, conducted a classified study on various cold storage technologies or applications and introduced these cold storage technologies and phase change materials whose phase change temperatures are in the range of 7–14 °C in detail.
LHTES for air conditioning systems Thermal energy storage is considered as a proven method to achieve the energy efficiency of most air conditioning (AC) systems.
In this review, we will mainly introduce cold energy storage applied in air conditioning systems. Compared with the conventional air conditioner, cold storage air conditioning has an additional energy storage tank, which is connected to both the evaporator and heat exchanger in parallel.
This review presents the previous works on thermal energy storage used for air conditioning systems and the application of phase change materials (PCMs) in different parts of the air conditioning networks, air distribution network, chilled water network, microencapsulated slurries, thermal power and heat rejection of the absorption cooling.
However, the chilled water storage system primarily utilizes sensible heat (4.2 J/g·°C) to store cold energy; therefore, it requires a relatively large storage tank compared with the PCM-based energy storage system that has a large latent heat of fusion.
Many researchers have conducted experimental or numerical research to make the cold storage technology better serve the air conditioning system. It is obvious that a lot of boons have been obtained.
A mixed cold storage air-condition system is a combination of a PCM cold storage tank, an ice cold storage tank, a refrigeration unit and a cooling supply unit, as shown in Fig. 5. The experimental studies showed that the PCM cold storage tank could increase COP of the chiller by more than 5% and increase cold storage capacity by 20%. Fig. 5.
