Energy saving technologies based on natural heat sources for heating outdoor air

[摘要] Estimation of energy input when heating external air during the winter period for the coal mines located in regions with severe climate is given. The basic diagram of external air heating in winter due to heat of mine water and the thermal pump is given. The parametrization procedure offered energy saving solutions is developed. The sustainable field of application of the thermal pump when heating external air depending on climatic and mining conditions is established.
