摘要

为了从理论上研究系统在环境温度改变时的运行特性

需要耦合系统各个部件的数学模型来确定系统的运行性能.在采用已有数据的基础上

对系统部件的运行参数进行拟合

建立起一组表示部件特性的经验关联式

进而联立求解

得到系统变工况下的运行特性.结果表明:在夏季温度为33～35 ℃、冬季温度为0～5 ℃时系统的运行性能最佳; 当环境温度向两端偏离最佳温度区域时

都将导致有效燃气消耗率增加

一次能源利用率降低; 制热工况一次能源利用率高于制冷工况

其最大值约是制冷工况最大值的1.7倍.

Abstract

In order to analyze system performance

empirical equations were fitted with the operating performance curves of the system parts. By coupling the equations

the relationships of primary energy ratio(PER)and effective gas consume rate(EGCR)with environment temperature were obtained. The result shows that the system had its optimum performance at 33-35 ℃ in summer and 0-5 ℃ in winter. When the environment temperature diverged from the appropriate temperature

the EGCR of the system would increase and the PER of the system would decrease. The system PER in heating conditions is higher than that in refrigerating conditions. Its maximum system PER in heating condition is about 1.7 times that in refrigerating condition.
