摘要

本文比较了三种不同的基于天然制冷剂的系统配置,包括制冷性能、每年的总等效变暖影响和拟议制冷系统的年耗电量。选择两种不同的冷负荷水平来代表一个典型的超市和一个便利店的应用。本研究选择的系统包括R717/R744级联系统配置、典型R744增压配置和R744并联压缩机增压制冷系统。英国伦敦和塞浦路斯拉纳卡的天气条件分别用于能源消耗和环境影响的建模,以代表温和和温暖的气候条件。

Analysis of Typical Booster Configuration, Parallel-Compressor Booster Configuration and R717/R744 Cascade Refrigeration System for Food Retail Applications. Part 2: Energy Performance in Various Climate Conditions.

This paper compares three different natural refrigerants based system configurations in terms of cooling performance, total equivalent warming impact per year and annual power consumption for the proposed refrigeration systems. Two different cooling load levels were selected to represent a typical supermarket and a convenience store applications. The systems selected in this study include the R717/R744 cascade system configuration, a typical R744 booster configuration and a R744 parallel-compressor booster refrigeration system. The weather conditions of London, UK and Larnaca, Cyprus, were used for the modelling of energy consumption and environmental impacts to represent moderate and warm climatic conditions respectively.
