Air carrier pilot reported they refused an aircraft due to its history of multiple engine over temps.

Narrative

Refused Aircraft X due to multiple (3 or more) Aircraft Maintenance Logbook write-ups for the #1 engine EGT over temping.This aircraft had a history of over temping the #1 engine; yet Maintenance would sign off the entry as EGT within maintenance tolerances; all 3 times prior. There were no corrective actions applied either time. Our flight also was leaving ZZZ with a full load of pax; outside air temperature at 100F; over max landing weight at TO by over 10;000 pounds; and the affected engine also had one of two fire detection loops inoperative and on MEL. I had no doubt given the local conditions and the deteriorated engine that this engine would over temp again and again. Align maintenance EGT tolerances and the Airbus EGT tolerances to match each other. Allow Maintenance Task Card to be more proactive when it comes to fixing aircraft sooner rather than later. Maintenance Task Card could have done an engine wash at a Maintenance Task Card base sooner; which I believe they did after the 4th write-up.
