In this research work, results on optimization of parameters related to energy consumption for indoor climate control of a building enclosure are discussed. The analysis is carried out for a building unit maintained at comfort level using Mitsubishi 1.5 ton of refrigeration split air conditioner. A mathematical model based on energy balance and experimental trials were used to compute energy consumption for space cooling/heating conditions. For the purpose of optimization, six control variables at three levels have been chosen from environment, thermo-physical properties, and geometrical variables. Taguchi optimization was carried out using L₂₇ orthogonal arrays to obtain an experimental test strategy for cooling and heating modes, which gives rise to two sets of parameters. With the implementation of utility concept, a single set of optimum level parameters were obtained for both heating and cooling mode operations. Taguchi technique predicted 1.606 kW and 1.252 kW as optimum energy consumption for space cooling and heating modes, respectively with 95% confidence level. Inside humidity ratio, overall heat transfer coefficient and wall to window ratio are predicted as the most influencing parameters for both cooling mode and heating mode operations by the Taguchi method and utility analysis.

在这项研究工作中，讨论了优化与建筑围护结构室内气候控制能耗相关的参数的结果。该分析是针对使用三菱 1.5 吨制冷分体式空调保持在舒适水平的建筑单元进行的。基于能量平衡和实验试验的数学模型用于计算空间冷却/加热条件的能耗。为了优化的目的，从环境、热物理特性和几何变量中选择了三个级别的六个控制变量。使用 L ₂₇进行田口优化正交阵列以获得冷却和加热模式的实验测试策略，这会产生两组参数。随着公用事业概念的实施，为加热和冷却模式操作获得了一组最佳水平参数。田口技术分别预测 1.606 kW 和 1.252 kW 作为空间制冷和制热模式的最佳能耗，置信度为 95%。通过田口方法和效用分析，室内湿度比、总传热系数和墙窗比被预测为对制冷模式和制热模式运行影响最大的参数。
