Abstract:
Study achievements and progress in cold air distribution systems which are combined with ice storage systems were summarized in recent years. It was found that research of cold air distribution systems was focused on both economical efficiency evaluation and ventilation as well as thermal comfort evaluation. The economical evaluation mainly depended on parameters of indoor air, supplied air temperature and selection of outlet. The influence of less economizer cycle's operating times due to using cold air distribution systems on annual economical efficiency of air-conditioning system was analyzed. Otherwise, the assessment of ventilation and thermal comfort mainly depended on if the structure of cold air jet was reasonable and if certain indexes which described the indoor air's quality and thermal comfort could reach the standard. Then, some potential investigation orients of cold air distribution systems in the future were put forward.
