    摘要: A measurement apparatus (100), which is arranged on a pipe (101), and is configured to measure the liquid content of a medium within the pipe (101); said apparatus comprises: a light transmission member (210), a light generation device (203), and a light reception device (204); the light generation device (203) is configured to emit emission light toward the light transmission member (210) that passes through an outer boundary wall (214) of the light transmission member (210) and has a preset emission angle, and the light reception device (204) is configured to receive reflection light after the emission light is reflected by an inner boundary wall (215) of the light transmission member (210). The measurement apparatus (100) can directly detect whether liquid is carried in a gaseous refrigerant exiting from an evaporator, as well as measure the amount of carried liquid. The refrigeration system can adjust a throttling apparatus in a timely manner according to a measured result, and prevents the performance of the refrigeration system and a compressor from being affected.

    摘要: The present application provides a falling film evaporator. The falling film evaporator comprises a housing, a gas outlet, a cover, a gas flow channel, and a plurality of flow guide members. The housing has a length direction and a height direction, and the housing defines an accommodating cavity. The gas outlet is provided at the upper portion of the accommodating cavity. The cover is provided in the accommodating cavity and defines a cover accommodating cavity, the cover accommodating cavity has a lower cover opening located below, and the cover accommodating cavity is configured to accommodate at least one part of a heat exchange tube bundle. The gas flow channel is located between the housing and the cover and enables the lower cover opening of the cover accommodating cavity to be in communication with the gas outlet. The plurality of flow guide members are arranged in the gas flow channel along the height direction of the housing. Here, in the height direction of the housing, one of two adjacent flow guide members is connected to the housing and is separated from the cover by a certain distance, and the other of the two adjacent flow guide members is connected to the cover and is separated from the housing by a certain distance. The falling film evaporator in the present application has the advantage of being high in gas-liquid separation efficiency, and the machining process of the flow guide members of the falling film evaporator is simple.

    摘要: Disclosed in the present application is a blade and an axial flow impeller using same. The blade comprises a blade tip, a blade root, a leading edge, a trailing edge, an upper surface and a lower surface. The upper surface and lower surface are disposed opposite each other; the blade tip, the blade root, the leading edge and the trailing edge surround the upper surface and the lower surface, and connect the upper surface and the lower surface. The blade is rotatable about a rotation axis, the rotation axis being perpendicular to a normal plane. The blade tip comprises a blade tip base part and a blade tip trailing part, the blade tip base part being close to the leading edge, and the blade tip trailing part being close to the trailing edge and being bent upwards relative to the blade tip base part. An angle of attack of a chord of the blade tip trailing part is greater than an angle of attack of a chord of the blade tip base part, wherein the angle of attack is an acute included angle between the chord and the normal plane. The blade of the present application can provide a large air volume, and has higher static pressure and higher efficiency.
