Question 2

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