1.3.4 Electronic Expansion Valve (EEV)
The EEV is designed for modulating control of the refrigerant mass flow with precision. The EEV collects
temperature and pressure signals at the same time to accurately regulate the refrigerant flow. The EEV's
wide operating envelope also lowers down the condensing pressure, thereby resulting in significant
energy savings.
 Designed for modulating control of the refrigerant mass flow with precision
 Ensures effective control on super-heating at t
he end of the evaporator
 Better low load capacity
 Designed for easy Installation-and-Service
