I don't recommend the refrigerator. I tried this one year, ended up with mushy rotten bulbs. Refrigerator can be too damp and temperature varies too much (bulbs along the back wall actually froze).. Fruit in the same refrigerator give off a gas that will also cause bulbs to rot. In zone 9A there isn't a place, indoors, that is really cool enough to let the bulbs go truly dormant. You best bet is to leave them in the pots out of sunlight, stop watering and let them dry out completely for a few weeks. The leaves will eventually die back. Some gardeners repot in fresh soil to jump start the bulbs into flower production after dormancy. In the South, we are just fighting Mother Nature since dormancy depends on day length, temperature, and dryness. I've given up on trying to force them for winter bloom. Mine are all in the ground, they die back when the nights get into the 30s, and will start to put up new growth as the nights get back into the 40s, as early as late Feb in milder winters. Just a warning for keeping them outside year round In zone 9A: If you have frost, cover the bulbs with a frost blanket or mulch heavily so the bulb itself doesn't freeze.
