Airport central air conditioning energy storage

How important is air conditioning in airport terminals?

The energy consumption attributabled to the central air conditioning system of the airport terminal constitutes around 40–60 % of the total energy consumption of the airport. Therefore, the necessity for energy conservation and carbon reduction within the airport terminal is increasing.

Are airport air-conditioning systems energy efficient?

Airports, as typical large-scale structures akin to small cities, exhibit high energy consumption and considerable potential for renewable energy generation . Therefore, the energy efficiency and flexibility of airport air-conditioning systems have received extensive attention.

How much electricity does an AC system consume in Chinese airport terminals?

This research investigated the AC systems in seven Chinese hub airport terminals by a large-scale on-site measurement. The average annual electricity consumption was 177 kWh/ (m 2 · year), in which 30–60% was consumed by AC systems. The terminal device of AC systems is one of the key components restricting the cooling performance.

Can air-conditioning systems flexibly adjust indoor temperatures?

Air-conditioning systems, as significant energy consumers with considerable flexibility, play a crucial role in integrating renewable energy and regulating power systems. This paper delves into the capability of air-conditioning systems in airports to flexibly adjust, particularly examining how varying cooling loads impact indoor temperatures.

Why are air-conditioning systems important?

The integration of renewable energy sources has led to notable supply-demand imbalances due to their intermittent nature. Air-conditioning systems, as significant energy consumers with considerable flexibility, play a crucial role in integrating renewable energy and regulating power systems.

How efficient are HVAC systems in airport terminals?

The efficiency of HVAC systems to meet the round-the-clock demands for cooling in a large area like the airport terminal depends on the individual efficiency capabilities of individual subsystems like compressors, chillers and cooling systems.
