Energy storage for building air conditioning

What is thermal energy storage?

Thermal energy storage (TES) is one of several approaches to support the electrification and decarbonization of buildings. To electrify buildings eficiently, electrically powered heating, ventilation, and air conditioning (HVAC) equipment such as a heat pump can be integrated with TES systems.

Can thermal energy storage be used in building integrated thermal systems?

Thermal energy storage in building integrated thermal systems: A review. Part 1. active storage systems - ScienceDirect Thermal energy storage in building integrated thermal systems: A review. Part 1. active storage systems TES implementation in buildings should be as helpful as possible for architects and engineers.

How to integrate a thermal energy storage active system?

Fig. 1 presents different ways to integrate the thermal energy storage active system; in the core of the building (ceiling, floor, walls), in external solar facades, as a suspended ceiling, in the ventilation system, or for thermal management of building integrated photovoltaic systems.

What are the benefits of thermal energy storage?

Advances in thermal energy storage would lead to increased energy savings, higher performing and more affordable heat pumps, flexibility for shedding and shifting building loads, and improved thermal comfort of occupants.

Does a building air conditioning system work at 100% capacity?

Realistically, no building air conditioning system operates at 100% capacity for the entire daily cooling cycle. Air conditioning loads peak in the afternoon -- generally from 2 to 4 PM -- when ambient temperatures are highest, which put an increased demand for cooling and electricity.

Why do we need integrated energy storage systems?

Integrated designs are required in active systems such as renewable energy facilities (i.e. photovoltaic, solar thermal) or energy efficiency HVAC systems. Many studies have been focused on improving the efficiency of these technologies by incorporating thermal energy storage systems that implies an additional storage volume .
