Refrigerants for deep mine refrigeration.

Number: pap. ID: 914

Author(s) : CALM J. M.


The operating conditions for deep mine refrigeration differ from conventional comfort conditioning and typically are more extreme. The thermal loads are less dependent on ambient air temperatures, cooling requirements are nearly continuous, and system reliability is critical for miner survival, health, and productivity. Refrigerant selections must consider looming environmental phase-outs of some common choices as well as new considerations. First, electricity prices are increasing in many mine locations. Second and particularly in some developing countries, inadequate power supplies are forcing demand limits or even curtailments to make capacity available for other uses. Third, mines are going deeper to reach previously untapped or previously less economic minerals. The greater depths both increase thermal loads and heighten flammability concerns with more limited egress. Additionally, mining firms are under pressure to be socially responsible, to avoid mandates and attract investment. This paper reviews refrigerant options for deep mine systems.
