The Influence of Wall Structures to Air Conditioner Energy Consumption Based on the Characteristics of Intermittent and Loculose Energy Use

Abstract:

In some areas like south of China, energy is used in part time of the 24 hours and part space of the buildings, that is the characteristics of intermittent and loculose energy use. The energy consumption of the air conditioner can be calculated from the transient state with the help of numerical computing method. Among different wall configurations of self-insulation, internal insulation and external insulation walls, it shows that self-insulation and internal insulation walls performs better than external insulation walls in energy saving. The energy stored by walls which account for the most part of the energy consumption can be sharply reduced in the configurations of self-insulation, internal insulation walls.
