PROBLEM TO BE SOLVED: To solve the problem of conventional devices and methods such as that the air blast range by the heating or cooling by air conditioner lies to the opening of a show case in a conventional shop such as supermarket, a convenience store, or the like, that the chill of the air curtain of the show case leaks to the passage in front of the show case and buyers and others feel cold and uncomfortable, that the temperature near an illuminator is high and is used inefficiently, and that the power used in the power system where the illuminator is connected is unbalanced depending upon the time zone. SOLUTION: An air conditioner or a blower is installed so that the wind zone distribution of the air blown out of an air conditioner within a shop may not spread to the air curtain of a show case but may spread to the front passage. Moreover, the input of an air conditioner or an illuminator is controlled, based on the temperature near the illuminator. Moreover, the power system is changed, according to the quantity of used power or the power rate. |
