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

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.
