摘要

采用分布参数法

对双蒸发器冷藏车制冷系统的空调侧和冷藏侧蒸发器建立了数学模型

并 对新型混合制冷剂R404A 在空调和冷藏2 种工况下的换热和流动情况与R22 和R134a 进行了模 拟分析比较. 结果表明

在空调和冷藏工况范围内

R404A 在两蒸发器中的换热量仅略小于R134a 而明显高于R22

制冷剂侧压降虽然大于R22

但却比R134a 小很多. 在双蒸发器冷藏车制冷系统 中

R404A 表现出换热性能好、压降小的特点

兼有了R134a 和R22 的优点

并能够适用于比 R134a 更低的冷藏温度.

Abstract

Wit h dist ributed parameter method

mat hematical model s of an air conditioning (A/ C) evaporator and a ref rigeration evaporator in t he dual2evaporator ref rigerator cars were presented. The simulation analysis and comparison of t he heat t ransfer and flow characteristics of R404A

R22

and R134a were performed under A/ C and ref rigeration operating conditions. The result s show t hat t he cooling capacity of R404A is a lit tle lower t han t hat of R134a but much higher t han t hat of R22

and t he pressure drop of R404A is higher t han t hat of R22 but much lower t han t hat of R134a under t he bot h conditions. R404A has good heat t ransfer and low pressure drop per2 formance

and can be used in lower ref rigeration temperat ure than R134a in t he dual2evaporator ref rigerator cars system.
