16. ELECTRONIC EXPANSION VALVE CONTROL
The most proper opening of an electronic expansion valve
is calculated and controlled under the present operating
condition based on the following values.
The compressor frequency, the temperatures detected by
the discharge temperature sensor, the indoor heat-exchanger
sensor, the outdoor heat-exchanger sensor, and the outdoor
temperature sensor.
Pulse range
The EEV is set up at 480 pulses when a compressor is stopped.
Initialization (Input of 528 pulses toward closing direction) is operated under the following condition.
* When the power is turned on.
* 4 hours has passed since the last initialization, and 3 minutes has passed after the compressor stop.
(If 12 hours has passed since the last initialization, the compressor is compulsorily stopped.)
