摘要： Systems, methods, and computer-readable mediums are provided for improving the efficiency of a filter-type oil separator in a cooling system including a compressor that pumps a mixture of lubricating oil and refrigerant through the filter-type oil separator. The filter type oil separator is configured to receive a first portion of the mixture from the compressor, and a bypass line is configured to bypass a second portion of the mixture around the filter-type oil separator. The bypass line ensures a sufficient amount of oil is present in the compressor.

摘要： Assemblies, apparatuses, and methods to extract or convey a material from a source of the material may include a vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may include a compressor housing having a vacuum source, a cooling system, and a vacuum controller. The vacuum source may include a compressor powered by an electric motor and positioned to cause a vacuum flow between the source of the material, and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber positioned to receive at least a portion of the vacuum flow from, and attenuate sound generated by, the vacuum source. The compressor housing and sound attenuation chamber of the vacuum generation and sound attenuation assembly may be arranged compactly on a common chassis for ease of transport and deployment.

摘要： An electric compressor integral with a drive circuit incorporates a compression mechanism section, a motor for driving the compression mechanism section, and a motor drive circuit. A refrigerant gas chamber having a refrigerant gas expansion space, into which refrigerant gas is introduced, is formed between a drive circuit installation section and a motor installation section, by a first partition wall provided on the drive circuit side and a second partition wall provided on the motor side, the side opposite the drive circuit side. The refrigerant gas chamber is interrupted by the first partition wall against the drive circuit installation section and is communicated with the motor installation section by a through hole that is provided in the second partition wall and through which the refrigerant gas can pass.
