The Most Unfavorable Loop and the Thermodynamic Stability
摘要
Since the pipe network is the most critical component of HVAC water system, the optimization control for pipe network is becoming more significant. This chapter provides the definition and identification method of the most unfavorable thermodynamic loop (MUTL) under operating and regulating conditions. Furthermore, it introduces an innovative concept of pipe network stability known as thermodynamic stability, which aims to address stability issues arising from the operation and regulation of the HVAC water system. This concept is developed based on the characteristics of the HVAC water system and the control strategy of the terminal air-conditioning equipment.
