Energy storage air conditioning thermal simulation

What is a thermal energy storage air-conditioning system?

Building envelope composition and heat transfer coefficient. This thermal energy storage air-conditioning system is mainly composed of an air source heat pump (ASHP), an energy storage tank, a circulating water pump, an air handle unit (AHU), and a variable air volume box (VAV box), fan coils and control system.

What is a thermal energy storage system?

A thermal energy storage (TES) system is a good alternative solution for demand-side management to shift the AC electricity usage from peak hours to off-peak hours, thereby also reducing the overall carbon footprint compared to a conventional air conditioning system.

What is thermal energy storage for space cooling?

Thermal Energy Storage (TES) for space cooling, also known as cool storage, chill storage, or cool thermal storage, is a cost saving technique for allowing energy-intensive, electrically driven cooling equipment to be predominantly operated during off-peak hours when electricity rates are lower.

What are the limitations of thermal energy storage systems for building cooling?

As stated above, traditional thermal energy storage systems for building cooling, such as ice, chilled water, and phase change material (i.e. organic, inorganic, and hydrated salts) are limited by low efficiency, slow response time (due to its low thermal conductivity) and necessity of large equipment sizing.

What is an Enn model for a thermal energy storage air-conditioning system?

An ENN model is developed for a thermal energy storage air-conditioning system. Both load forecasting and TES prediction is established. A demand response is implemented by field test based on the ENN model. Maximum energy reduction without comprising occupants comfort level is achieved.

Can a PCC-TES (phase change composite-thermal energy storage) improve AC performance?

This case study explores whether or not the concept of integrating a PCC-TES (Phase Change Composite-Thermal Energy Storage) into an AC system can have a positive impact on the overall air conditioning system performance and electricity consumption. The validated simulation model was used to address the performance comparison. 7.1.1.
