Energy Consumption And Energy-saving Based On The Beijing Area For Air Source Heat Pump

Start by selecting a building in Beijing to study the data through the typicalhousing as a study site, the measured air-conditioning running, aggregate air sourceheat pump system operating parameters in the running of the building. By the climaticconditions of the Beijing area, air source heat pump system to environmentalconditions, the actual run-time analysis of the measured data and on this basis than toexplore the ordinary water air-conditioning simulation analysis of the system in theBeijing area the feasibility and economy. Provides practical guidance for the Beijingarea and the surrounding areas of similar climatic application of air source heat pumpsystem, also made preparations for further study.Studies have shown that air source heat pump system in the Beijing area is quitefeasible. But in winter, the air-conditioned room is uncomfortable, the unit system isinstability and frosting. There are two options to system energy-saving for the above.One is water-air source heat pump transformation; the other is transformation ofsolar assisted air source heat pump. The article closely linked to the study, came toconclusion through the construction of system simulation and scientific analysis ofenergy consumption simulation calculation construction by using the related dada.Transformation scheme: storage energy to water, and then release the energy todefrost, so that the operation reliability, energy efficiency ratio, thermal comfort of theair source heat pump system is improved in winter. Because of the simpler system andthe lower investment, the program is more suited to the renovation project. But itcannot fundamentally solve the problem that the heat efficiency of air source heatpump is not enough under the low temperature environment. Reconstruction schemeof two: using solar energy as the evaporator heat or auxiliary heat source, so that thesituation of evaporation of outdoor is improved greatly, unit energy efficiency ratio isgreatly improved, and operation cost is greatly reduced. The second program cancompletely make the efficiency of the air source heat pump grow in winter. But itsinitial investment of transformation is relatively high. The cost recovery needs verylong time.In this paper, the application feasibility of the air source heat pump technology in Beijing throughout the year to run is analyzed. The reasonable and scientificimprovements are put forward to the traditional air source heat pump air conditioningtechnology. It achieves the purpose of saving the energy, and gives some reference todeal with the building energy-saving questions of cold region similar Beijing.
