A refrigerating system includes a bypass channel, a second temperature sensor and a controller, the bypass channel communicates a first channel with a second channel and is provided with a throttling portion, which is located between an inlet and an outlet of the bypass channel; a sensing head of the second temperature sensor is arranged in the bypass channel, and is between the throttling portion and the outlet of the bypass channel and close to the outlet; when the system is in operation, a working medium in the bypass channel where the sensing head of the second temperature sensor is located is in a saturated state, and the controller obtains sensing results of a first temperature sensor and the second temperature sensor, determines the difference between the sensing results, and determines the degree of superheat at an inlet of a compressor according to the difference.
A refrigeration system, comprising a compressor, a condenser, an expansion valve, an evaporator, a first passage, a first temperature sensor, and a second passage, wherein the evaporator and the compressor are in communication with each other through the first passage, a sensing head of the first temperature sensor is arranged in the first passage, the second passage is arranged between the condenser and the evaporator, and the expansion valve is configured to form a throttling position in the second passage, and the refrigeration system further comprises:
An expansion valve assembly, applied to a refrigeration system, wherein the expansion valve assembly comprises an expansion valve, a first temperature sensor, a bypass passage, a second temperature sensor, and a controller, the expansion valve comprises a valve body and a valve core, the valve body has a first hole passage and a second hole passage, a sensing head of the first temperature sensor is arranged in the second hole passage, the valve core is configured to cooperate with the first hole passage to form a throttling position, and the first hole passage and the second hole passage are in communication with each other through the bypass passage;
