Abstract


The construction industry as an important part of the development of the national economy , has played a very crucial role in promoting China's social modernization process . But at the same time, high pollution and high energy consumption of the building industry as people 's awareness of environmental protection increasingly prominent , reduce building energy consumption has become an inevitable choice in the industry . Sea water source heat pump ( SWHP ) as a new heating (cooling ) has a traditional HVAC equipment can not match the great advantages of technology, energy saving and emission reduction , its relatively high cost , however , makes it the promotion and application has been very limited . It is for this reason , its economy from the perspective of project management evaluation . The article first introduces the sea water source heat pump and its technical characteristics , analyze its running costs , to prove in order to compare the full life-cycle costs and benefits of the economy of the heat pump ( compared to traditional heating and cooling ) . The accuracy of a variety of mathematical models SWHP and traditional heating (cooling ) costs - commercial electricity to predict and take advantage of the sales price of its upstream coal industry to measure the predicted results . Monetization of the pollution effect of the power generation industry , model building , power plant pollution product unit value were calculated , to prepare for the economic evaluation of the heat pump in the later based on the theory of environmental value . Finally, Dalian City , a sea water source heat pump works as an example, by calculating the contrast Although SWHP than traditional central air conditioning cost to more than double , but only by virtue of the electricity savings , six years can be filled more investment , average annual operating cost savings of more than 1500 million . In terms of environmental benefits , the annual use SWHP about the creation of the environmental value of 395 million . Discussed above , we can draw the following conclusions : a life - cycle perspective , SWHP is entirely feasible economically , and will create a huge environmental benefits for the whole community .
