摘要
APF作为空调机组性能评价指标,其测试计算过程复杂,影响因素繁多。提出了实际运行APF——aAPF,并建立了APF及aAPF计算的数学模型,在给定的不同因素组合下进行全年模拟。结果显示各aAPF值相差最大可达36.9%,与APF相比相差可达-19.9%～8.5%。通过该模拟结果分析APF值使用范围,并给出了APF的修正建议。
As a performance evaluation factor of air conditioning,APF has a complex computational process with many factors.In this paper,actual Annual Performance Factor-aAPF is proposed,the mathematical model of APF is established,and the simulation is performed under different conditions.The result shows that the maximum difference of aAPFs can be 36.9%,and the difference between aAPF and APF can be-19.9%~8.5%.The application range of APF is analyzed by the simulation results,and a suggestion is offered that APF should be modification.
