Abstract
The flow of refrigerant is controlled by a strategy that strives to seek and maintain a fluctuating superheat condition. The control system causes optimal use of the evaporator coil by ensuring that the refrigerant in the coil is in the liquid state. A temperature sensor at the evaporator coil exit senses refrigerant temperature and the control system regulates refrigerant flow so that the liquid dry out point (transition between liquid state and superheat state) occurs in the vicinity of this sensor. Thus a single sensor may be used to effect closed loop control.
