Comparison And Analysis Of Various Energy Sources As Heat And Cold Source Air Conditioning System

The environmental pollution and energy crisis have been two major problems in current society,and how to enjoy life while paying the least price gradually becomes the human consensus.It has become the development direction of air conditioning to create comfortable environment for buildings with little energy consumption,as far as possible,and the development and utilization of natural cold/heat source can bring both energy saving and environmental protection benefits to air conditioning,so it has been gotten more attention from researchers.The underground layers as a natural source of heat,contains heat resistance,with relatively small fluctuations in each year and dosn't subject to the conditions of other geographical factors and interference.The energy storage of underground layers is abound and the storage area is wide,so it become an innovative form of renewable energy in the clean energy and regional idealized hot or cold natural resource.Taking a park in Beijing as an example,this paper introduces the compound energy system of geothermal cascade utilization + energy storage type ground source and water source heat pump in detail,making use of various available forms of energy to complement each other and maximizing the economic benefits in the aspects of initial investment and operation costs,based on the comparative analysis of distribution,operation cost,initial investment,investment recovery period and carbon emission reduction of five energy modes,we can conclud that " the compound energy system of geothermal cascade utilization + energy storage type ground source and water source heat pump " is the best reasonable scheme.The exploitation and utilization of geothermal resources can reduce atmospheric pollution and protect atmospheric environment,and contains certain social benefits.At the same time,the low price of geothermal energy,with good economic benefits,is in line with the green energy situation advocated by China and further promotes and implements the policy of "bringing back clean water and blue sky for mankind".
