冷凍・冷蔵ショーケースの温度警報発報方法
Document Type and Number:
Japanese Patent JP6654329
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress damage of commodities caused by delay in issuing temperature alarm and no issuing of temperature alarm by adjusting a timing of issuing temperature alarm according to a degree of increase of inside temperature of a freezing/refrigerating showcase.SOLUTION: A temperature alarm issuing method includes a process for measuring an inside temperature of a refrigerating/freezing showcase, a process for determining that the inside temperature increases to a predetermined alarm temperature or more, a process for determining a correction lapse time obtained by multiplying the lapse time of every lapse time from the increase of the inside temperature to the alarm temperature or more by a multiplication rate predetermined according to temperature difference between the alarm temperature and the inside temperature, a process for determining an integrated correction lapse time by integrating the correction lapse time, a process for determining that the integrated correction lapse time reaches a predetermined alarm issuing integration time, and a process for issuing the temperature alarm when the integrated correction lapse time reaches the alarm issuing integration time.SELECTED DRAWING: Figure 2
