Abstract

This research presents an energy performance analysis of the heat pump system with internal heat exchanger (IHX). The mathematical model of the heat pump outlined in this paper has been created by the author, it is steady-state with lumped parameters. The experimental validation of the model has been carried out using R1234yf and R134a as refrigerant. The aim of this work is to compare the energy performance in a wide range of operating conditions of a monitored heat pump system using both refrigerants. Finally, the heating capacity for R1234yf was lower from 0.63 % to 7.54 % compared with R134a, while the compressor power was similar from 0.12 % to 3.51 %. The COP values of R1234yf were lower than those obtained of R134a, ranging from 1.39 % to 4.22 %.

采用R1234yf和R134a的IHX热泵系统对比分析

本文对带内热交换器的热泵系统进行了能量性能分析。本文所概述的热泵数学模型是由作者建立的，它是具有集总参数的稳态模型。以R1234yf和R134a为制冷剂对模型进行了实验验证。这项工作的目的是比较在广泛的运行条件下，监测热泵系统使用这两种制冷剂的能源性能。与R134a相比，R1234yf的热容量从0.63%降低到7.54%，压缩机功率从0.12%降低到3.51%。R1234yf的COP值低于R134a，为1.39% ~ 4.22%。
