<P>PROBLEM TO BE SOLVED: To provide an open showcase of high energy saving performance by suppressing temperature rise in a showcase storage space due to the influence of air current outside of a showcase body. <P>SOLUTION: In the open showcase 100 including a control means 21 for controlling an air distribution amount of an inner fan 20 according to the difference between a temperature in the storage space 13 and a prescribed target temperature of the storage space 13, and forming an air curtain 5 at an opened face 14 of the storage space 13 by sucking the air supplied from a supply opening 16 from a suction opening 17, the control means 21 controls the air distribution amount of the inner fan 20 on the basis of the temperature in the storage space 13, after operating the inner fan 20 in a state of lowering the air distribution amount to a prescribed amount for a prescribed time, when the air distribution amount of the inner fan 20 reaches a prescribed maximum value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
