w2 When the correction opening of suction super heat is 0, correct the LEV opening by dischaege temperature.

(1)LEV opening correction by suction super heat (COOL, DRY)

(Suction super heat) = (Minimum gas pipe temperature) - (Evaporation temperature) When COOL and DRY , correct the LEV openings corrected from the table below

(a)Correction by the separate super heat

Correct the LEV separately by temperature difference between each gas pipe temperature thermistor and evaporator temperature thermistor.

1Calculate each super heat of the unit from the expression below;

(Super heat) = (Gas pipe temperature thermistor) - (Evaporation temperature thermistor)

2Select a minimum super heat from among them.

3Correct an each LEV is corrected opening is corrected by difference between each super heat and minimum super heat.
