摘要
住宅厨房空间因存在高温燃烧热源和烹饪空气污染源,是热舒适和空气品质问题相对集中的区域.随着生活水平的提高,人们对厨房热湿环境的舒适性要求越来越高,新的厨房空调产品也逐渐出现,而现有的负荷研究无法为厨房空调的设计提供有效依据.为了探索住宅厨房空调冷负荷及其影响因素,以某典型住宅厨房为例,研究了厨房冷负荷的大小分布、来源构成、影响变量以及地域差异.结果表明,厨房空调冷负荷集中分布在800～1600W/m2,潜热负荷占比高达75%,室外补风在显热负荷和潜热负荷中平均占比30%和71%.地域差异导致峰值负荷大小和出现小时数不同,这对空调选型有重要影响.现有的厨房空调需要匹配合理的运行策略和补风形式才能满足厨房冷量需求.
Abstract
The residential kitchen space is a relatively concentrated area for thermal comfort and air quality problems due to the presence of high-temperature combustion heat sources and cooking air pollution sources.With the improvement of living standards,people have higher and higher requirements for the comfort of the thermal environments in kitchens,and new kitchen air conditioning products have gradually emerged,while existing load studies cannot provide an effective basis for the design of kitchen air conditioning.In order to explore the air conditioning cold load and its influencing factors in residential kitchen,a typical residential kitchen is studied on the size distribution,source composition,influencing variables,and geographical differences of the kitchen cold load.The results show that the air conditioning cold load is concentrated in the distribution of 800～1600 W/m2,with latent heat load accounting for up to75%,outdoor make-up air accounting for 30%of the sensible heat load on average,and 71%of the latent heat load on average.Geographical differences result in different peak load sizes and hours of occurrence,which have important implications for air conditioning selection.The existed air conditioners for kitchen need to be matched with reasonable operation strategies and forms of make-up air to meet the kitchen cooling demand.
