The Measurement And Energy-saving Analysis Of Ground Source Heat Pump Demonstration Projects In Hefei

Ground source heat pump technology as the new technology in HVAC thatused by renewable sources, which development is becoming more and more quicklyin our country and get strongly supported by state. In2006, the Ministry ofFinance-Housing and Urban-Rural Development Ministry has launched theconstruction of renewable energy demonstration projects, At the same time, theMinistry also provides that the demonstration projects needs for testing andacceptance of assessment. In2008,"renewable energy demonstration projectevaluation guide " has introduced, this regulations has explained the contents of thetests and engineering evaluation method in detail, and has regulated the energyefficiency evaluation of ground source heat pump system.At the end of2009, the city of Hefei had became one of the "Nationalrenewable energy demonstration cities". Subsequently, in the city of Hefei,RuralConstruction Committee announced the first batch of21renewable energydemonstration project, including7projects about the ground source heat pump.Faced with this situation of an increasing number of ground source heat pumpsystems engineering in Hefei, currently, ground source heat pump system is stilllack of practical engineering tests and the contrast energy analysis of the testresults, it is still lack of ground source heat pump system in Hefei integrity of theinvestigation and summary analysis, this article will as a center for research.Renewable energy demonstration project, for example,this paper first willintroduces a ground source heat pump system energy efficiency evaluation methodand evaluation criteria. The Secondly, to use DeST software to simulate calculatethe energy consumption in the traditional air conditioning program. Finally, basedon the measured data of the project, in-depth analysis of the test results to study theoperation of the system. At the same time, it is calculated to obtain the actualenergy consumption of ground source heat pump system. By comparing thetraditional air-conditioned analog data, highlighting the ground source heat pumpsystem with the advantages of energy efficiency and environmental benefits.In addition, the other ground source heat pump demonstration projects testresults obtained through actual testing in Hefei comprehensive computationalanalysis, ground source heat pump system application in the Hefei different building types. In the overall analysis,this article tries to discover the problemsthat exist in the test, and then, give a solution, specific measures to controlproblems, as well as the design and operation recommendationsThrough the research, this paper attempts to research the results to indicatethe suitability of the ground source heat pump system in Hefei area; At the sametime, through the introduction of the sample projects, to make the detectiontechnology of ground source heat pump system to some extent understand andimproved. In addition, the study on the collection and analysis of the measuredresults can also provide some reference value for the engineering design andpractice.
