According to Boyles law the volume is inversely proportional to the pressure applied providing the temperature remains constant. So for example if a condensor coil were sized for a temp difference of 15k it would equate to a certain pressure. Now if i were to put in a larger coil the volume would increase and the pressure would drop causing a lower temperature difference say for example 5k. My question is applying this rule to the evaporator side of the system. If i we're to increase the size on the evap thys increasing the volume and decreasing the pressure? I've always been led to believe that a larger coil would cause lower evap temp difference thus a higher low side pressure but this seems to contradict the theory i've applied to the condensor?
