Performance analysis of a coal mine air supply system based on a multienergy complementary energy supply system
Published on 2026-06-03 by @OXFORD
Abstract: AbstractMine ventilation air heating in severely cold regions is commonly supplied by coal-fired boilers, leading to high energy use and environmental impacts. This study proposes a multienergy complementary energy supply system integrating air-source heat pumps (ASHPs), a cascade water-source heat pump, and thermal energy storage to ensure reliable shaft anti-freezing (3°C) and flexible operation under time-of-use electricity pricing. A dynamic TRNSYS model was developed for a coal mine in Wuh[...]
Our summary: This study presents a multienergy complementary energy supply system for mine ventilation heating in cold regions. A dynamic TRNSYS model was validated, showing a 7.57% error margin. The proposed system enhances performance in extreme cold, reducing costs and emissions significantly.
