摘要
本文通过仿真系统模型的建立,确定诊断逻辑、修正诊断方向。对一实际工程中地源热泵系统建立TRNSYS模型,运用控制变量法,进行了"水系统流量不足"等2类6组对照试验,验证了以温度、流量为系统特征值确定地埋管系统故障诊断方向的有效性。
The diagnostic logic is established by establishing the simulation system model to determine the diagnostic logic and correct diagnostic direction. In the established TRNSYS model which is based on a actual project,"water system flow shortage"and other six groups controlled trials in two aspects were also established by use of control variables method. Temperatures and flow rates were verified as the system eigenvalue to determine the effectiveness of fault diagnosis direction.
