Advantages of energy storage chiller

Why is thermal energy storage important for solar cooling systems?

Thermal energy storage (TES) is crucial for solar cooling systems as it allows for the storage of excess thermal energy generated during peak sunlight hours for later use when sunlight is not available, thereby extending the cooling coverage of solar-driven absorption chillers .

How does an absorption chiller work?

Here, the absorption chiller is connected directly to the solar thermal collector that provides the required heat energy to operate the chiller. The chiller produces a cooling effect during sunshine hours and charges the cold storage. The stored cool energy can be discharged to cover the cooling requirement of a building.

Can solar cooling systems be controlled with absorption chillers?

Discussed various control strategies of solar cooling systems with absorption chillers. Solar cooling technology is a potential solution for air conditioning and thermal comfort in buildings. However, the intermittent nature of solar energy is a significant challenge for the widespread adoption of this technology.

Can solar energy be stored in a chiller?

While cold energy can be stored when excess solar energy leads to extra generation of cold energy from the chiller. The stored cold energy can be discharged to cover part of the cooling demand. Both cold and hot storage can be in the form of sensible or latent heat.

Can a multi-effect absorption chiller meet the thermal energy demand?

Florides et al. (2002) simulated an 11kW domestic absorption cooling machine and optimized that 15 m 2 CPCs (tilted at 30°) is sufficient to meet the thermal energy demand along with 0.6 m 3 hot water storage tank. Some more research is required to adopt these collectors to match the thermal energy demand of multi-effect absorption chillers.

Are vapor absorption chillers a good option?

PVT collectors are very active to meet the electrical and thermal energy demand simultaneously in the same collector area. Hence it could be a better option to meet the diverse need of the electrical and thermal energy need of the vapor absorption chillers. However, limited physical installations have been reported in the literature.
