DPF electronic expansion valve is a kind of promising throttling device suited for the demands of mechano-electronic refrigeration system. It can give fast response and a wide modulating range. And moreover it can work under the preset modulating method to achieve the excellent quality of superheat modulation. So it can guarantee the chiller to be used efficiently and the system to be run with steady-state, low energy losses and accurately controlled temperature. It is used widely in refrigeration system such as inverter air conditionor.
WORKING PRINCIPLE:
When the inputting voltage pulses are applied to the coil in ***ermined sequence, a rotational magnetic field is produced. Thus the rotor, which is made of permanent magnetic material, is rotated by the magnetic torque, making the valve pin up or down through the transmitting structure, and to change the mass flow area of valve. In this way, the mass flow can be adjusted automatically to ensure that the system is kept in the best state.
