Abstract
Air-conditioning systems in commercial buildings play a vital role in the demand respond (DR) of cities. At present, many researches are focused on zone temperature reset strategies which are used frequently in the commercial buildings of the United States. However, this strategy requires the support of the energy management and control system (EMCS), which is not suitable for most commercial buildings in China. This paper focuses on the DR effect of the chiller-side control strategies in Chinese commercial buildings. Taking an office building as the research object, the coupling thermal inertial model of the building and the air conditioning system was built; based on the coupling model, the demand reduction effects of the typical chiller-side DR control strategies, including intermittent shutdown, chiller quantity reduction and chilled water temperature increase, were simulated; and the characteristics and applicability of these strategies were pointed out.
