Heating method and heat recovery potential prediction of underground railway station using waste heat from equipment rooms

Adopts the water-loop multi-connected split heat pump technology to recycle the waste heat of the equipment room for an underground railway station’s heating. Analyses the particularity of the water-loop multi-connected split heat pump system, and discusses the special precautions. Calculates the best temperature of loop water, discusses the operating characteristics, and predicts the heat recovery potential.
