“…(3) In the third category, q evap and q cond match q sol,cool and q sol,heat , respectively. Thus, no auxiliary equipment is required to be installed in this case (Bergero and Chiari, 2010Zhao et al, 2011;Yamaguchi et al, 2011;Zhang et al, 2013). There is no information mentioned about capacity matching in the studies in this category and therefore, it is not clear whether capacity matching exists under design conditions or all operating conditions of the heat-pump LDAC system.…”

“…It was found that the proposed system was not only able to solve the problem of condensation; it also improved the responsiveness to internal load changes. In another study, a temperature and humidity independent control (THIC) system was implemented and tested in the atrium of an office building [9]. It was shown that radiant floor cooling and separate humidity control increased the temperature of the chilled water and improved system efficiency.…”

“…If a CWS is adopted in such an air-conditioning system, the temperature difference of the CWS system is no more than 5°C (considering the temperature differential loss due to heat exchangers). However, in temperature and humidity independent control (THIC) air-conditioning systems (also called as ''independent control of temperature and humidity system''), the indoor air temperature and humidity can be regulated independently using a separate temperature control subsystem and a humidity control subsystem respectively [19]. The return water temperature from the cooling coils of the temperature control subsystem can be increased significantly (e.g., from 12°C to 21°C) and the storage density of CWS can be increased consequently.…”

a r t i c l e i n f o Article history: Available online xxxx Keywords:Proactive demand response Smart grid Chilled water storage Temperature and humidity independent control Air-conditioning systems a b s t r a c t Power demand response is considered as one of the most promising solutions in relieving the power imbalance of an electrical grid that results a series of critical problems to the gird and end-users. In order to effectively make use of the demand response potentials of buildings, this paper presents a novel airconditioning system with proactive demand control for daily load shifting and real time power balance in the developing smart grid. This system consists of a chilled water storage system (CWS) and a temperature and humidity independent control (THIC) air-conditioning system, which can significantly reduce the storage volume of the chilled water tank and effectively enable a building with more flexibility in changing its electricity usage patterns. The power demand of the proposed air-conditioning system can be flexibly controlled as desired by implementing two types of demand response strategies: demand side bidding (DSB) strategy and demand as frequency controlled reserve (DFR) strategy, in respond to the day-ahead and hour-ahead power change requirements of the grid, respectively. Considerable benefits (e.g., energy and cost savings) can be achieved for both the electricity utilities and building owners under incentive pricing or tariffs. A case study is conducted in a simulation platform to demonstrate the application of the proposed system in an office building.
