3.12.7 Control when frequency is changed
When the target discharge pipe temperature control is active, if the target frequency is changed
for a specified value in a certain time period, cancel the target discharge pipe temperature
control and change the target opening of the electronic expansion valve according to the shift.
3.12.8 Target Discharge Pipe Temperature Control
Obtain the target discharge pipe temperature from the indoor and outdoor heat exchanger
temperature, and adjust the electronic expansion valve opening so that the actual discharge
pipe temperature become close to that temperature. (Indirect SH control using the discharge
pipe temperature)
Determine a correction value of the electronic expansion valve compensation and drive it
according to the deflection of the target discharge temperature and actual discharge
temperature, and the discharge temperature variation by the 20 sec.
