1.3.7 Sensor Location
1.3.6 Valves and Functions
EEV: Electronic Expansion Valve
EEV controls super heat at the evaporator outlet
and controls the refrigerant supply quantity
to the evaporator by means of temperature
sensors installed at the evaporator outlet and
inlet.
DMV: Discharge Modulation Valve
DMV is usually used at fully-open. However,
while in defrosting operation, the opening is
adjusted to conduct release control.
EMV: Economizer Modulation Valve
EMV controls the refrigerant supply quantity to
the economizer while in pull-down operation
by adjusting EMV opening by means of
the temperature sensors mounted at the
economizer outlet and inlet. The EMV is also
used for the discharge pipe temperature control
and charging control during defrost and heating
operation.
ESV: Economizer Solenoid Valve
ESV is opened and closed in conjunction with
the EMV.
LSV: Liquid Solenoid Valve
LSV is opened while in compressor operation. It
is closed while in defrost and heating operation
and automatic pump-down.
HSV: Hot gas Solenoid Valve
HSV is opened while in defrost and heating
operation to supply hot-gas from the
compressor to the evaporator and drain pan.
It is also opened to equalize the pressure to
protect compressor in case of large pressure
difference of high and low pressure while in
compressor start up.
RSV: Reheat Solenoid Valve
RSV is opened while dehumidification
control operation to supply hot-gas from the
compressor to the reheat coil.
PRV: Pressure Relief Valve
PRV is mechanical type pressure regulating
valve. It releases the refrigerant to the low
pressure side when the pressure rises
abnormally.
