A machine with a housing, wherein the housing has a body formed into a cylindrical structure extending along an axial direction. The housing includes a plurality of radiation ribs extending along the axial direction and disposed circumferentially outside the body. Further, the housing includes at least one pair of ventilation windows arranged to radially protrude outward from two ends of the body in the axial direction respectively, so as to dispose a part of the plurality of radiation ribs therebetween; and at least one ventilation duct arranged radially outside the radiation ribs along the axial direction and coupled to the at least one pair of ventilation windows, enabling an internal heat radiating airstream of the electric machine to flow through the ventilation duct. The radiation ribs also can be configured at the position where the ventilation duct is disposed.

Provided is an intelligent irrigation control method for rice fields based on a cloud service platform and a system thereof. Constructing a planting condition data set and a condition coefficient, monitoring the current water supply environment of crops, and constructing a water supply coefficient. If the water supply coefficient is lower than the water supply threshold, based on the current growth data of crops, a plurality of corresponding irrigation strategies are matched from the pre-constructed crop irrigation knowledge graph, and the target strategy is selected from a plurality of irrigation strategies; constructing an irrigation observation coefficient set, and constructing irrigation coefficient. If the irrigation coefficient is lower than the efficiency threshold, use the trained strategy optimization model to optimize the target strategy, and control the irrigation coefficient based on the optimized target strategy to complete the irrigation of crops in the irrigation area.

A compressor may include first and second scrolls, a seal assembly and a valve ring. The first scroll may include a first end plate having a discharge passage, a modulation port, and a biasing passage. The modulation port may be in communication with a first pocket formed between spiral wraps of the first and second scrolls. The biasing passage may be in communication with a second pocket formed between spiral wraps of the first and second scrolls. The modulation valve ring is axially displaceable relative to the seal assembly and the first scroll between first and second positions. The valve ring may abut an end plate of the first scroll and close the modulation port when in the first position. The valve ring may abut an axially-facing surface of the seal assembly and is spaced apart from the end plate to open the modulation port when in the second position.
