摘要: A fan, comprising blades (102), an upper hub (111), and a lower hub (112). Each blade (102) comprises a connecting part (211). The connecting part (211) is clamped between a lower surface of the upper hub (111) and an upper surface of the lower hub (112). The lower surface of the upper hub (111) is provided with an upper hub connecting area, and the upper surface of the lower hub (112) is provided with a lower hub connecting area. An upper surface and a lower surface of the connecting part (211) are separately provided with a junction surface extending from the connecting part (211). The lower surface of the upper hub (111) and the upper surface of the lower hub (112) are separately provided with a matching surface matching the junction surface. The junction surface and the matching surface are arranged in the radial direction and/or circumferential direction of the upper hub (111) and the lower hub (112), and are configured to match with each other to impede the movement of at least two blades (102) in the circumferential direction and/or radial direction with respect to the upper hub (111) and the lower hub (112). The fan structure can prevent the movement of the blades (102) with respect to the upper hub (111) and the lower hub (112). The connecting part (211) and the fan body (201) are not easy to break and can be easily assembled, such that better stability can be ensured while the cost is low.

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: A heat exchanger for a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a shell having an inlet configured to receive refrigerant and an outlet configured to output the refrigerant. The heat exchanger also includes a refrigerant distributor disposed within the shell, and multiple evaporating tubes disposed within the shell and positioned below the refrigerant distributor. The refrigerant distributor includes a perforated plate having multiple holes, each hole extends from a top surface of the perforated plate to a bottom surface of the perforated plate, and a center point of each hole is substantially aligned with a centerline of a respective evaporating tube.
