AI Technical Summary

Technical Problem

Existing air compressors have relatively low energy efficiency when heating and cooling, and the practicality of compressed air energy storage is poor, especially when there is unstable natural energy source, there are problems of wind and solar power curtailment.

Method used

By modifying the air compressor and combining it with a pressurized air storage device, a constant pressure air storage device, and a vortex tube unit, an energy storage-type hot and cold air system is constructed. The vortex tube is used to separate hot and cold air, and combined with a solar heat-absorbing coating and a fresh air fan, a high-efficiency hot and cold air supply is achieved.

Benefits of technology

It enables energy storage during off-peak hours and efficient output of hot and cold air during non-off-peak hours, solving the problem of wind and solar power curtailment caused by unstable natural energy sources. It has a high energy efficiency ratio and is suitable for drying, building HVAC, and energy centers, achieving energy saving, cost reduction, and emission reduction effects.
