8.4 ELECTRONIC EXPANSION VALVE

ELECTRONIC EXPANSION VALVE

The Electronic Expansion Valve (EEV) is an electroni- cally controlled expansion valve. The control algo- rithms to control the EEV reside in the micorprocessor software. The superheat setpoint can be programmed on the control panel.

The purpose of the EEV is to meter a ﬂow of liquid refrigerant into the evaporator to maintain a superheat

setpoint. The refrigerant ﬂow direction is designated by an arrow on the expansion valve body.

There are two safeties associated with the EEV; Low Superheat Cutout and Sensor Failure Cutout.
