Table (d): Indoor Air Temperature Shifting

1.Target room temperature shift value (dGetaDst)

To offset the absolute gap between detection temperature with actual room temperature.

The heat exchanger unit’s temperature is different based on operation mode, it become the action operation mode value.

2.Room temperature shift value (dGeta)

When compressor ON/OFF, correction of detected room temperature by shift value during defrost etc.

i) Initial value when operation starts, or changing the actual operation mode.

Set the offset value at each operation mode. However, in order to improve the heating start up efficiency, the offset value will be changed based on the gap between setting temperature and room temperature.

ii) Updating during operation

During operation, it will compare with the target room temperature offset value at specific period, then the room temperature will be updated.

Update the room temperature offset value (dGeta)

Temperature condition

Room temp. offset value after modified (dGeta)

Target room temp. offset value > Room temp. offset value

dGeta + (0.5)

(dGetaDst > dGeta)

 

 

 

Target room temp. offset value < Room temp. offset value

dGeta - (0.5)

(dGetaDst < dGeta)

 

Target room temp. offset value = Room temp. offset value

Do not change

(dGetaDst = dGeta)

 

However, if the following condition is occurred, temperature cannot detect correctly and therefore no updating will be done.

Heating zone E and above (Temperature gap is big and great capacity increased)
