Should I use the recirculation button when running my air conditioning in the summer?

Is it true that you should have your recirculation button on all the time in summer when you are running the air conditioning?

Using the recirculation button in conjunction with your air conditioning can result in a consistently lower temperature, as the system is chilling the air from the cabin which is already cold rather than having to cool fresh air from outside, which is likely to be a higher temperature.
