| As people economic level promoting,people’s demand for quality of life is improving gradually,the popularity of air conditioning is also further expand,increase building energy consumption amount.Facing the energy situation is increasingly grim,development and utilization of new energy conservation technology have been more and more attention.Air source heat pump air conditioning system is based on outdoor air as heat and cold source of air conditioning mode,through the consumption of small amounts of electricity,the air of low grade heat energy into heat energy to take advantage of the high grade,heat pump technology is high efficiency and energy saving effect,can alleviate environment pollution problem at the same time,so there has been a lot of attention in recent years.The application of air source heat pump air-conditioning system is affected by the geographical environment,hindered the promotion of the system in the north.In this paper the application of air source heat pump system in northern region to carry on the case study,analysis of a Beijing hotel building heating air conditioning system engineering,and the rest hall building as a typical space related parameters,such as temperature,wind speed,relative humidity test,and according to the test data analysis,summer the runtime system can meet the requirements of air conditioning design specifications,the winter when the system running,although the comfort is a bit poor,but generally can meet the requirements.At the same time,in this paper,CFD software to computer simulation experiment,and the rest of the hall space CFD technology is one of the analog simulation,and it is widely used in hvac,the simulation results and experiment test of numerical control,found it’s a little biased,the conclusion and analysis of basic consistent,proved that the application of air source heat pump systems in Beijing area is feasible.In determining the feasibility on the basis of air source heat pump air conditioning system of the building adopts the economic analysis,and lithium bromide absorption refrigerating unit chiller + fuel furnace hot water,the analogy,concluded that running scheme of the system in Beijing area belongs to the most economic.Experimental test,the simulation results and economic analysis show that the air source heat pump air conditioning system running in Beijing area is feasible,for the region and similar environmental condition of application of the system to provide the reference in the region. |
