How does cooling/refrigeration help in maintaining the taste and shelf life of food products, especially CSD (Carbonated Soft Drinks)? For example, chilled drinks have a nicer taste than a normal drink and may have longer shelf life. Why is that?

It has a longer shelf life because the bacteria, (which is the reason it will go bad), cannot reproduce as fast in cold temperatures.
As far as taste goes with carbonated soft-drinks, I think it is mostly just about preference.
Refrigeration condenses the CO2 and allows for a "softer" bubble feel in the mouth.
As for shelf life of soda, it should not effect a "canned" soda one way or another.
