The indoor parameters are generally non-uniform distributed. Consequently, it is important to study the space cooling/heating load oriented to local requirements. Though the influence of indoor set point, heat sources, and ambient temperature of convective thermal boundary on cooling/heating load has been investigated in the uniform environment in previous research, the influence of these factors, particularly the convective heat gain/loss through a building envelope, on cooling/heating load of non-uniform environment has not yet been investigated. Therefore, based on the explicit expression of indoor temperature under the convective boundary condition, the expression of space cooling/heating load with convective heat transfer from the building envelope is derived and compared through case studies. The results can be summarized as follows. (1) The convective heat transferred through the building envelope is significantly related to the airflow patterns: the heating load in the case with ceiling supply air, where the supply air has a smaller contribution to the local zone, is 24% higher than that in the case with bottom supply air. (2) The degree of influence from each thermal boundary to the local zone of space cooling cases is close to that of a uniform environment, while the influence of each factor, particularly that of supply air, is non-uniformly distributed in space heating. (3) It is possible to enhance the influence of supply air and heat source with a reasonable airflow pattern to reduce the space heating load. In general, the findings of this study can be used to guide the energy savings of rooms with non-uniform environments for space cooling/heating.

室内参数通常是不均匀分布的。因此，研究针对当地需求的空间冷/热负荷非常重要。尽管在先前的研究中已经在均匀的环境中研究了室内设定点，热源和对流热边界的环境温度对制冷/制热负荷的影响，但这些因素的影响，特别是建筑物对流热损的影响对于非均匀环境的冷/热负荷，尚未进行研究。因此，根据对流边界条件下室内温度的明确表示，推导并比较了从建筑围护结构进行对流传热的空间冷热负荷表达式。结果可以总结如下。（1）通过建筑物围护结构传递的对流热与气流模式显着相关：在天花板供气的情况下，供热对局部区域的贡献较小，在这种情况下，供暖负荷比供热负荷高24％。底部供气的情况。（2）从每个热边界到空间冷却箱局部区域的影响程度接近于均匀环境的影响程度，而每个因素的影响，特别是送风的影响在空间加热中是不均匀分布的。（3）可以通过合理的气流模式来增强送风和热源的影响，以减小空间加热负荷。通常，本研究的结果可用于指导环境不均匀的房间进行空间制冷/供暖的节能。
