1-10. ELECTRONIC EXPANSION VALVE CONTROL
The most proper opening of the 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
and the outdoor temperature sensor.
The pulse range of the electronic expansion valve control is
53 ~ 480 pulses (Cooling) and 40 ~ 480 pulses (Heating).
The pulse range of the electronic expansion valve control is
53 ~ 480 pulses (Cooling) and 53 ~ 480 pulses (Heating).
At the time of supplying the power to the outdoor unit, the initialization of the electronic
expansion valve is operated (528 pulses are input to the closing direction).
The compressor won't enter operation status for 3 minutes after the compressor is stopped,
even if any operation is given.
At the time when the air conditioner is switched from the cooling mode to heating mode,
the compressor is stopped, and the 4-way valve is switched in 3 minutes later
after the compressor stopped.
