摘要
为满足空气源热泵冬季集中供热的需求,该文采用新型工质将空气源热泵的制热温度提高至90℃以上。首先建立高温空气源热泵的数学模型并对该系统进行理论计算,进而搭建高温空气源热泵试验台,分别在环境温度为0、5、10℃时对模拟结果进行实验验证,当热水进口温度为80℃时,系统实际COP分别较理论结果低5.9%、5.3%和1.7%。该空气源热泵相比现有技术提升制热温度40℃以上,因此具有较好的市场应用前景和推广意义。
In order to meet the demand of air source heat pump central heating in winter,this study uses a new working medium to raise the heating temperature of air source heat pump to more than 90℃.Firstly,the mathematical model of high-temperature air source heat pump is established to simulate the system,and then a high-temperature air source heat pump test bench is built to verify the simulation results at ambient temperatures of 0,5 and 10℃,respectively.When the inlet temperature of hot water is 80℃,the actual COP of the system is 5.9%,5.3%and 1.7%lower than the theoretical results,respectively.Compared with the existing technology,the heating temperature of the air source heat pump is increased by more than 40℃,so it has a good market application prospect and promotion significance.
