ENGLISH
The metering device is an electronic expansion valve. The
valve consists of an electrical operator and a valve body with
internal variable size orice. When operating, the PCB will
send pulses of voltage to the electrical operator. The operator
will then magnetically move the position of the metering
orice pin to vary refrigerant ow.
The metering device position is determined by input from
a Suction Line Temperature Sensor. The EEV will change
the internal orice size to maintain an acceptable level of
superheat.
During COOL MODE the valve meters low pressure
refrigerant to the indoor coil. During HEAT MODE the valve
meters low pressure refrigerant to the outdoor coil.
The electrical expansion valve is electrically connected to the
Main Control Board at PLUG CN-16.
The 4-Way Valve redirects the ow of refrigerant in the piping
circuit to allow the system to reverse the functions of the
indoor and outdoor coils. When de-energized in COOL MODE,
the valve will direct the refrigerant hot gas to the outdoor coil.
When energized in HEAT MODE, the valve will direct the hot
gas to the indoor coil.
The valve ow direction capability is controlled by an electrical
solenoid. When energized with 230 VAC, the solenoid will
magnetically move an internal slide within the 4-Way Valve to
change the direction of refrigerant ow.
The 4-Way Valve is electrically connected to the Main Control
Board at PLUG CN-10.
The Accumulator is located in the suction line circuit at the
entrance to the compressor. The accumulator helps prevent
liquid refrigerant from entering the compressor during run
operation.
The system has debris-catching strainers that protect internal
system components from contaminants in the refrigerant.
The strainer is a permanent part that is not typically replaced.
The liquid and gas seperator is located on the suction line
circuit before accumulator. It can help prevent the liquid
refrigerant entering the compressor during the operation.
