太阳能-空气源热泵联合运行系统方案设计及仿真模拟

Design and Simulation of Solar-Air Source Heat Pump Combined Operation System

随着经济的发展,社会能源消耗也在快速增长。巨大的能耗在给能源供给带来压力的同时,也产生了对环境污染等的社会问题。建筑能耗是社会能源消耗的重要组成部分,因此在目前煤改电的背景下,研究如何实现建筑的高效节能且清洁化的供热对节能减排战略具有重要意义。本文基于太阳能与空气源热泵技术的结合为学校学生宿舍楼中央热水系统的改造方案设计,利用TRNSYS软件搭建太阳能-空气源热泵联合运行系统及电加热器的仿真模型,在验证系统可行性的同时,分析系统运行能耗的影响因素,改造后取得显著的节能效果。

With the continuous development of the economy,social energy consumption is also growing rapidly.Huge energy consumption not only puts pressure on the energy supply,but also causes social problems such as environmental pollution.Building energy consumption is an important part of social energy consumption.Therefore,under the background of current coal-to-electricity reform,it is of great significance to study how to achieve efficient and energy-saving and clean heating of buildings.In this paper,based on the combination of solar energy and air source heat pump technology,the central hot water system of a student dormitory building has been designed,and the simulation model of solar-air source heat pump combined operation system including electric heater was established by using TRNSYS software to verify the feasibility of the system.At the same time,the factors affecting the energy consumption of the system are analyzed,and the significant energy saving effect after the transformation is obtained.
