Abstract
Systems and methods are provided for controlling an expansion valve of a climate control system evaporator coil. An evaporator coil temperature sensor senses temperature of refrigerant within the evaporator coil near the evaporator coil outlet. A controller determines a control set point based on the refrigerant temperature near the evaporator outlet. The control set point is used to determine a valve opening area to regulate refrigerant flow into the evaporator coil such that temperature of refrigerant at the evaporator coil outlet is within a temperature band having a lower bound within a predetermined range above the liquid-to-vapor transition temperature.
