Research on the evaluation of air conditioning of the solar energy or the wind energy-ground source heat pump based on the cost year-end value

摘要

This dissertation analyzed and evaluated air conditioning of ground source heat pump, air conditioning of the solar energy-ground source energy-ground source heat pump and air conditioning of the wind energy-ground source heat pump from the angle of technology and economy. First, it is analyzed that the operating principle, technical specialty and problems of air conditioning of ground source heat pump; Then, as an auxiliary heat source, solar and wind energy can solve problems of air conditioning of ground source heat pump in the running. Finally, with a civil dwelling in Urumqi as an engineering example, a comparative calculation is made of the air conditioning of ground-source heat pump plan, air conditioning of the solar energy-ground source energy-ground source heat pump plan and air conditioning of the wind energy-ground source heat pump plan. The initial investment, the annual operation cost, the annual maintenance cost, the cost year-end value and the life cycle cost (LCC) of three plans are given. The results indicated that the civil dwelling of air conditioning of solar or wind energy-ground source heat pump plan has the distinct economic advantages as an auxiliary heat source.
