摘要
分析了常规地下室用多联室内机选型方法构成的误差,然后运用过程设计思想,区分初选室内机的潜热与显热,充分考虑冷量随工况变化的特性,提出了一种新的选型方法,根据数学模型编制了相应的计算机程序,并给出了实例。建议厂家提供多联机的全工况数据或拟合的性能曲线方程,为选型提供方便。
In this paper,the error of conventional selection method for multi-connected air condition unit used to basement was analyzed.Considering the change of refrigerating capacity associated with various conditions,the theory of process design was used to develop a new method to distinguish between sensible heat and latent heat.According to mathematic model,the computer program had been obtained.Also,one instance had been given.For the purpose of selection convenience,it was suggested that manufacturers should provide full condition data or fitting performance curve equation.
