Abstract：A mine pneumatic water chilling unit based on the underground mine compressed air as a power could be mainly applied to a ice storage refrigeration and air conditioning of the refuge chamber in underground mine and could be applied to the mining and excavation gateway and other places re-quired to have a local temperature cooling.The mine pneumatic water chilling unit would have a struc-ture simple ,moving convenient ,safety reliable and other advantages.Under different environment temperatures ,the operation parameters of the mine pneumatic water chilling unit were measured from the experiment conducted.Under the condition of the environment temperature as 24.2℃ ,the paper analyzed the steadily decreasing of the cooling water temperature affected to the operation parameters of the water chilling unit and the analysis could provide the references to the optimized design ,applica-tion and selection of the pneumatic water chilling unit.
