An air conditioning system charged with R-410A is operating with a suction pressure of 130 psig which equates to a 45°F saturation temperature. If the manufacturer calls for a 15°F superheat, what should the suction line temperature be?
A) 45°F + 15°F = 60°F suction line temperature B) 45°F - 15°F = 30°F suction line temperature
C) 130 psig + 15°F = 190°F suction line temperature D) 130 psig - 15°F = 115°F suction line temperature
