Air-conditioning Usage Pattern and Energy Consumption for Residential Space Heating in Shanghai China

Air-conditioning (AC) is discontinuously used in Shanghai residential buildings during the winter time. The AC usage pattern, therefore, has great influence on its energy consumption. In order to figure out the space heating energy consumption for Shanghai residents, it's necessary to have an accurate description of AC usage model. In this study, questionnaire surveys and continuous measurements of 10 residents were done in Shanghai. Based on the Marcov Chain and AC usage conditional probability model, the descriptive parameters under three different energy levels were calculated according to test data. Then, the AC energy consumption is calculated by DeST-h software for validation. The results of this paper can serve as a reference for AC heating energy consumption studies. (c) 2017 The Authors.
