(3) LEV opening correction by discharge temperature

When LEV correction output is 0 pulse by the suction super heat at cool or dry operation, or dry operating, correct LEV is cor- rected according to the following table.

The target discharge temperature is determined according to frequency zone and number of operation unit of the compressor.

Correct the LEV opening according to difference between the target discharge temperature and discharge temperature.
