When summarizing the various settings shown in Figures 7 to 12, the systems and blocks of 10 merchandise display cases 101~110 are set as follows: System 1: 101~108 (master slave 101, slave slave 102~108). Block 1:101~106 (master slave 101, slave slave 102~106). Block 2: 107, 108 (master slave 107, slave slave 108). System 2: 109, 110 (master slave 109, slave slave 110). Blocks 1:109, 110 (master slave 109, slave slave 110) cooling control settings are as follows: System 1 (101~108): Usually. System 2 (109, 110): The usual defrost control settings are as follows: System 1 (101~108): Block unit. System 2 (109, 110): System unit In addition, the business hours of the reference time at which the cooling start and stop times are set are as follows: Summary (common). The business start time is 9:00, and the business end time is 20:00. System 1 (101~108) The cooling schedule is set as follows: Linked to business hours. Cooling starts 30 minutes before the start of business (8:30). Cooling stop 40 minutes after the end of business (20:40) The cooling schedule of System 2 (109, 110) is set as follows: Not linked to business hours.

After the setting is completed, the centralized control device CCU is transmitted to the terminal control devices TCU1 to TCU10 of the commodity display cases 101-110, and the cooling start and stop of each of the product display cases 101-110 are based on the above settings. The data is controlled by the terminal control devices TCU1 to TCU10.

In this way, after the end of the business hours, the merchandise display case, which has no obstacles even if the cooling is stopped, is based on the start and end time of the business, and the cooling start and stop times can be set based on the time difference from the time. Therefore, if the time difference is set in advance, even if the business hours of the store change, the cooling start and stop times of the merchandise showcase can be appropriately set by inputting only the changed business start time and end time. According to this, the setting error of the cooling start time to the cooling stop time and the business start time to the business end time is not generated, and it is possible to surely provide the product that is cooled at an appropriate temperature at the start of business.

In addition, the time difference required for the product display operation performed before the business start time and the time required for the product removal operation performed after the business end time can be set, so that it is possible to prevent the product display from catching up with the business start time and the like. By setting the cooling stop time to the maximum, it is possible to effectively reduce the energy cost of cooling down.

Moreover, the time difference can be set and applied in each block. Therefore, if a time difference from the system is set in each block and the business time is linked, a different cooling start and stop time can be set in each block. Further, appropriate cooling and non-cooling control is performed by the type of the displayed product, the cooling temperature, and the like.

In the above centralized management system, the cooling, non-cooling and cooling operation modes of the respective merchandise showcases 101 to 110 can be manually operated by the operation panel of the centralized control device CCU. This point will be described in detail below.
