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.
