Electronic expansion valve for room air conditioner control

Electronic-expansion-valve

Electronic expansion valve is used in Inverter air conditioning system to adjust flow of refrigerant automatically. Thus the air conditioner can always stay at the optimized working conditions with quick cooling, precise temperature control, low energy consumption, etc. This valve can also be used for other controls. This valve is reversible and can control the flow under either cooling or heating condition.

Series O Electronic Expansion Valve (EXV) is mainly composed of valve body and coil. The controller in the air conditioning system can control the step motor of EXV to synchronize the turning of geartrain which convert the rotation of gears to a pull/push force and mover the valve pin axially which can change the flow area and flow of refrigerant accordingly.
Characteristics of Series O EXV: low noise, high resolution, long life.
Function of Series Q EXV: The controller sends pulse signal to the coil which controls the rotor synchronizing the turning of feed screw and nut, converting the rotation to movement of valve pin. Thus the flow area and flow of refrigerant will be changed accordingly. The stopper controls the stroke of valve pin within 0<->500P by slide rings.
Series Q EXV is composed of:The EXV is driven by PM type step Motor(Claw pole permanent Motor) which consists of two relative separate parts: 1)step motor coil;2)multi pole rotor valve body. The coil is fixed onto the body through a clipper.

The main Characteristics of Series Q EXV: small size, light, the flow path is versatile to handle noise of refrigerant, high reliability and long life.

Series R EXV is mainly used in HP water heater with CO2 to adjust flow of refrigerant automatically. Thus the water heater can always stay at the optimized working conditions with quick heating, precise temperature control, low energy consumption, etc. This valve can only be used in one direction to automatically control the flow under heating condition.

Series R Electronic Expansion Valve (EXV) is mainly composed of valve body and coil. The pulses applied to the coil drive the current to control the step motor inside the valve which can synchronize the turning of valve pin to open or close the valve. The flow will change automatically.
Characteristics of Series O EXV: small size, high pressure proof, reliable operation.

    Hi,

    I am looking at the series R valve, for a domestic hot water heat pump application. The documentation indicates that flow should be from A to B in heating, but I am unable to identify which port is A and which is B. Please could you confirm the port numbering and perhaps provide a schematic of a recomended install?

    Thanks
    Leon
