Abstract

The invention relates to the technical field of temperature control equipment, and provides a temperature detection device, storage equipment, a refrigerator and a storage chamber temperature control method. The temperature detection device comprises a sealed cavity and a pressure sensing module arranged in the cavity; the cavity is used for storing a phase change medium capable of generating phase change; and the pressure sensing module is used for collecting pressure in real time in the process that the phase change medium in the cavity changes from the first phase to the second phase. According to the temperature detection device, the storage equipment, the refrigerator and the storage chamber temperature control method, whether the target temperature is reached in the storage chamber or not can be judged in time according to the pressure change generated on the pressure sensing module when the phase change medium configured in the device generates phase change, and the wrong influence of external factors of the storage chamber on temperature detection is avoided; and energy loss is caused.

Description

technical field [0001] The invention relates to the technical field of temperature control equipment, in particular to a temperature detection device, a storage device, a refrigerator and a storage room temperature control method. Background technique [0002] The temperature sensor is a sensing element that converts the temperature change into a resistance change, and is mainly used for temperature detection, temperature compensation, temperature control, overload protection and other devices. [0003] Refrigerators generally use NTC (negative temperature coefficient) thermistor sensors. Negative temperature coefficient sensors are sensors whose zero-power resistance value decreases as the temperature increases within a certain operating temperature range. At present, the accuracy of temperature sensors used in refrigerators is generally 0.5°C, which is not high in accuracy and is easily disturbed. [0004] For example, use a temperature sensor to determine whether the tem...
