摘　　要：根据目前现有燃池加温系统的结构、材料性质和运作条件,利用ANSYS软件对日光温室燃池辅助加温系统进行有限元分析,模拟T型、圆形、方形的燃池结构,比较3种形状对土壤加温效果,选出最优形状。同时以T型燃池为例,模拟1.2、1.3、1.4m池深,确定燃池的适宜深度。结果表明:在外界条件相同的环境下,具有相同深度、相同池顶面积的圆型燃池对土壤加温效果最好;T型燃池深度1.3m对土壤加温效果最好。通过对燃池深度和形状的分析,可为今后燃池加温系统的设计提供理论依据。According to the current existing fire-pit heating system of structure,material properties and operating conditions.With help of ANSYS software,finite element analysis of fire-pit heating system in the solar greenhouse.Tfire-pit,circular fire-pit,square fire-pit were simulated,the effect of soil heating was studied between three types of firepit,to select the best type.Meanwhile,as T-fire-type as example,depth of 1.2m,1.3m,1.4mwere simitaled,to select the suitable depth of fire-pit.The results showed that,in the outside conditions under the same environment,the same depth,the same pool area of circular,square,T-fire-pit had the best effect of soil heating.Using the T-fire-pit,the fire-pit depth of 1.2mhad the best effects on the soil heating.Through the analysis of the fire-pit depth and shape,could provide theoretical basis for the design of fire pool heating system in the future.
