There is no need to refrigerate your chocolate. It will do just fine at room temperature (68-70 degrees) for long periods of time. In the summer, air-conditioning is fine. In the winter, please try to keep the chocolate away from any heat source as it will soften (70F) and even melt (80).
Chocolate may be frozen but it must first be protected by wrapping with plastic wrap or waxed paper because when the chocolate comes out of the freezer the package will get moisture on it like any frozen food, and it will be wet which can make the chocolate sticky and not shiny.
