The invention provides a noise reduction assembly, a refrigerant heat exchange mechanism and refrigeration equipment, and relates to the technical field of noise elimination and noise reduction. The noise reduction assembly comprises a body comprising an air duct; the air duct penetrates through the body, is connected with the ventilation opening and extends in the first direction; in the first direction, the interior of the body is divided into a plurality of silencing layers, and each silencing layer comprises at least one silencing cavity; the silencing cavity is located on the periphery of the air duct and communicates with the air duct. Wherein the thicknesses of every two adjacent silencing layers in the first direction are different. 本发明提供了一种降噪组件、冷媒换热机构和制冷设备，涉及消声降噪技术领域。降噪组件包括：本体，包括风道；风道贯穿本体，用于连接通风口，风道的延伸方向为第一方向；沿第一方向，本体内划分出多个消声层，每个消声层包括至少一个消声腔；消声腔位于风道周侧，且与风道连通；其中，相邻两个消声层在第一方向上的厚度不同。
