Research On Energy Consumption Of Air Conditioning And Saving Energy Technology Of Housing In Guangzhou City

Guangzhou is situated at the coastal area where the economy is developed, the residential building air-conditioner inventory is huge, and increases progressively year by year.. The air conditioning inventory keep increase has brought the enormous pressure for the urban electrical network it is known that air conditioning electricity consumption has accounted for about 30% which the electrical network always shoulders in the summer peak time. Therefore it has the important meaning regarding the housing air conditioning energy consumption's research.This article survey the power consumption carry on as the household in a saving energy residential district to month by month in 2008. It has obtained the whole year annual average power consumption is 31.44kWh/㎡ a, the annual average air conditioning power consumption is 11.63 kWh/㎡ a. Afterward it analyzed the power data for various building in this residential district ,the finally result had indicated housing faced and the position has the importance effect to the air conditioning energy consumption, the housing that faced unreasonable the average air conditioning power consumption to be possible higher than 33.7% compared to the mean value.Moreover, in order to understanding the saving energy measure's actual result for saving energy residential district, we had selected other one residential district that not use the energy conservation measure to carry on the air conditioning energy consumption investigation to take the contrast, it had obtained the summer air conditioning power consumption for two residential district through the computation, it carries on the contrastive analysis to the power consumption data. The finally result show that the residential district used energy conservation measure could reduce 34% air conditioning power consumption.Finally, in order to understand the influence of saving energy measure on the housing air conditioning energy consumption that under the actual work and rest, we had carried on questionnaire survey in the saving energy residential district, it obtained the inhabitant's actual work and rest pattern. Through simulated the effect under the kind of energy conservation energy measures for housing under in DEST-h that take the actual work and rest as the input parameter, the finally result show that each saving energy measures has achieved the anticipated design purpose.
