    摘要： A method for identifying a state of a stream of refrigerant includes capturing a plurality of sample images of a sensor for sensing the stream of the refrigerant, processing each of the plurality of sample images to identify a first color indicative of a dry refrigerant and a second color indicative of a wet refrigerant. The method also includes calculating an aggregated volume of each of the first color and the second color, wherein the aggregated volumes of the first color and the second color indicate a dry refrigerant or the wet refrigerant respectively in the stream. Further, the method includes comparing an aggregated volume ratio of the first color and the second color with a first threshold ratio and a second threshold ratio and determining the state as one of a dry state, a transient state, and a wet state based on the comparison.

    摘要： The present invention discloses a ambient temperature barocaloric refrigerating machine based on a barocaloric effect, which belongs to the technical field of refrigerating machines. The refrigerating machine comprises a high-precision high-pressure electric injection pump, a barocaloric element, heat exchange fluid, a cold end heat exchanger and a hot end heat exchanger. The phenomena of heat release after pressurization and heat absorption after depressurization are generated due to phase change through a barocaloric medium under the action of the high-pressure injection pump. The heat exchange fluid flows back and forth between the barocaloric refrigerators and exchanges heat and cold. The high-precision high-pressure electric injection pump of the present invention provides pressure for the barocaloric refrigeration cycle, and the pressure is constantly output. The pressurization form is fluid pressure, which well overcomes the defect of uneven transfer of mechanical pressure. The pressurization oil is also used as the heat exchange fluid and in direct contact with a sample. Pressure-driven heat and cold are directly brought into the hot end heat exchanger and the cold end heat exchanger to complete the cycle, thereby reducing the heat loss.
