Abstract
A cooling storage in the present disclosure cools air to be supplied to a display chamber through a refrigeration cycle including an evaporator. The cooling storage includes a drain receiving portion disposed under the display chamber, a first temperature sensor disposed in the drain receiving portion, a second temperature sensor disposed below the first temperature sensor in the drain receiving portion, and a control unit that detects a temperature difference between a detected temperature of the first temperature sensor and a detected temperature of the second temperature sensor.
Claims8
A cooling storage that cools air to be supplied to a display chamber through a refrigeration cycle including an evaporator, the cooling storage comprising:
- a drain receiving portion disposed under the display chamber;
- a first temperature sensor disposed in the drain receiving portion;
- a second temperature sensor disposed below the first temperature sensor in the drain receiving portion;
- and
- a control unit that detects a temperature difference between a detected temperature of the first temperature sensor and a detected temperature of the second temperature sensor.
A method for controlling a cooling storage that cools air to be supplied to a display chamber through a refrigeration cycle including an evaporator, the cooling storage including
- a drain receiving portion disposed under the display chamber,
- a first temperature sensor disposed in the drain receiving portion,
- a second temperature sensor disposed below the first temperature sensor in the drain receiving portion, and
- a control unit that controls operation of each part of the cooling storage, wherein
- the control unit executes a detection step of detecting a temperature difference between a detected temperature of the first temperature sensor and a detected temperature of the second temperature sensor.
A cooling storage management system comprising:
- a cooling storage disposed in a store;
- and
- a management device configured to be communicable with the cooling storage, wherein
- the cooling storage cools air to be supplied to a display chamber through a refrigeration cycle including an evaporator,
- the cooling storage includes
- a drain receiving portion disposed under the display chamber,
- a first temperature sensor disposed in the drain receiving portion,
- a second temperature sensor disposed below the first temperature sensor in the drain receiving portion, and
- a control unit that detects a temperature difference between a detected temperature of the first temperature sensor and a detected temperature of the second temperature sensor, and
- the control unit included in the cooling storage notifies the management device of a detection result of the temperature difference.
