Exergy economics analysis of mine water source heat pump systems

Taking the costs of unit cooling or heating exergy and unit cooling or heating quantity as evaluation index, sets up the thermodynamic models of mine water source heat pump system and refrigeration unit plus boiler room system separately, and analyses the thermal efficiency of the two systems. With a project, calculates and compares thermodynamic costs of the two systems. The results show that from the viewpoint of thermal economics, the mine water source heat pump system is obviously better than refrigeration unit plus boiler room system, particularly in winter condition.
