摘要
蛋鸡叠层笼养舍在纵向通风情况下鸡舍断面空气不能充分混合，鸡舍热湿环境受围护结构传热影响较小。建立了鸡舍非稳态环境预测模型，引入围护结构传热影响系数对模型进行改进，并提出简化模型。验证结果表明，简化模型能满足生产管理要求。
A transient mathematic model was provided to analyze the thermal behaviour, air temperature and moisture conditions of layer housing in summer. The response factor was used to calculate the heat transfer through opaque structure. Because of high bird density,large ventilation rates and tall erect cages, air flow can not be fully mixed. The insulation of existing house has little effect on the inside air thermal environment. An efficiency index which describes the influence of the heat transfer through opaque structure was given to build an improved and simplified model.
