Unlike small amounts of thermostatically controlled appliances (TCAs)

the central air-conditioner (CAC) has huge potential ability of demand response by virtue of its large capacity. Focusing on the features of CAC demand response

an integrated model is proposed to describe CAC’s thermodynamic aspects

including the main devices

circulating water system and terminal devices. This paper presents a new CAC control strategy based on temperature adjustment of partial terminal devices which differs from previous methods in concentrating on all the CAC’s terminal devices. The effects of different precision controlling conditions can be reflected by using this model and strategy. Modeling results show that the proposed approach has better performance and efficiency by rational adjustment.
