Disclosed is an electronic expansion valve.

The electronic expansion valve comprises a core structure (50A).

The electronic expansion valve enables effective reduction of the height of the valve body on the basis of the operational reliability.

An electronic expansion valve comprises a housing (1), a magnet (2) and a lead screw (3).

Malfunction of electronic expansion valve in indoor unit of other system

The electronic expansion valve (EEV) operates with a much more sophisticated design.

The structure of the expansion valve enables the sight glass (8) to be easily attached to the valve seat assembly (7).

An electronic expansion valve (48) is positioned between the first heat exchanger (34) and the second heat exchanger (52).

The first opening degree of the electronic expansion valve in the (n+1)th preset period is adjusted according to the difference ΔΤd.

The outlet (82) of the electronic expansion valve (80) is connected to the inlet (62) of the evaporator (60) by means of a tube (74).

The heat exchanger can be isolated by closing an electronic expansion valve, actuating a refrigerant management valve, or both.

The system comprises a compressor (1), an indoor heat exchanger (7), an electronic expansion valve (4), and an outdoor heat exchanger (3).

The outlet (54) of the condenser (50) is connected to the inlet (81) of the electronic expansion valve (80) by means of a tube or conduit (73).

Subsequently, a second control for the electronic expansion valve (216) can be repeatedly adjusted by evaluating the first refrigerant temperature and the slope.

The Vitocal 300-A is the first air/water heat pump with digital scroll technology and an electronic bi-flow expansion valve.
