Energy Consumption Analysis Of Aluminum Alloy Venetian Blinds Movable Ezternal Sunshade In Hot Summer And Cold Winter Areas
Aluminum alloy venetian blinds have many advantages, such as, high corrosion resistance, sun shading, insulating heat and so on. And it is the new extemal sunshading facility which has a significant energy-saving effect and Its prospects of the development will be quite broad. This paper, on the basis of the climate features of hot summer and cold winter zones, taking a south window of Nanjing as the model and making use of MATLAB software to program, calculated in theory the energy consumption of the extemal window which had a aluminum alloy venetian blinds movable external sunshade facility and that of the extemal window without external sunshade facility in summer for different types of windows. After calculation results were compared and analyzed, it can be fred that the solar radiation heat gain of the external window reduces by 42.27％ and the solar direct radiation heat gain reduces by 96.37％ in the situation of external sun shading. The cumulative air-conditioning cooling load of the external window which has the external sunshading facility reduces respectively by 33.57％, 28.56％, 28.07％, 34.10％, 29.86％ and 29.28％ for ordinary aluminium alloy single-glass window, hollow glass window and Low-E hollow glass window and PVC plastic single-glass window, hollow glass window and Low-E hollow glass window, compared with that of the external window which has no extemal sunshading facility. So it can be seen that energy consumption of the external window which has a movable external sunshading facility can be reduced greatly in summer in hot summer and cold winter zones.
