Compare The Cooling(Heating) Supply Project Of Luoyang Gongshui Mansion

With the growth of economy and synthetic national power in China, concentrated air conditioning system was more and more frequently used in the building for civil use. The energy consumption and cost of concentrated air conditioning system reasonably puzzled many building owners and air conditioning system designers. The cooling(heating) supply and use cost occupy 60 - 70% in all the air conditioning system, different cooling(heating) supply projects were widely different. The paper compares the cooling(heating) supply projects in practical work-Luoyang Gongshui Mansion.With the use of BIN weather data, the paper analyzed the supply cost of four different projects by use, by means of economy and heat economy. Establish the heat economy model of four cooling(heating) supply project, compare the net present value of the four, analyse the cooling(heating) supply cost and refrigerant to the influence of surroundings, compare the four cooling(heating) supply project all in all and recommend the practical project.
