Cooling capacity relation with air temperature.


I have noticed on some ac units the total cooling capacity at 80F air temperature is more than the cooling capacity at 75F air temp while the RH is 50% at both the temperatures. I mean why the total cooling capacity is not more at 75F?


Please help me understand how that is possible. Although the sensible cooling capacity is higher at 75F.

Less heat in the air at 75 then at 80. The A/C can only remove heat if its there to remove.
Next, 50% RH at 80 is a lot more moisture in the air then at 70.
