Abstract

Abstract:

A model of air source heat pump air conditioning system is built based on TRNSYS.Based on the model, the operation of air source heat pump air conditioning system is simulated using the meteorological data of five climatic regions in China.The result shows that air source heat pump air conditioning system can be applied to most areas in China except severe cold regions, and the COP can reach to 3.2-3.5.Besides, the effect of heat transfer coefficient of building's exterior wall on the performance of air source heat pump air conditioning system is analyzed.It shows that the load of building and the energy consumption of the air conditioning system are linearly related to the heat transfer coefficient of building's exterior wall, and reducing the heat transfer coefficient of the external wall can effectively reduce the energy consumption.

Key words: air source heat pump, TRNSYS, energy consumption, climatic region, building envelope, heat transfer coefficient

摘要：

基于TRNSYS软件建立了空气源热泵空调系统的仿真模型。基于该模型，分别利用我国五大气候区域的气象数据对空气源热泵空调系统进行了仿真分析，仿真结果表明，空气源热泵空调系统能够适用于我国除严寒地区之外的大多数地区，COP能够达到3.2~3.5。此外，还分析了建筑外围护结构传热系数对空气源热泵空调系统运行性能的影响，结果表明建筑负荷与系统能耗和外墙传热系数呈线性相关关系，降低外墙传热系数能够有效地降低系统能耗。
