Patent number: 10544799Abstract: Provided are a centrifugal compressor gas-supplementing structure and a compressor using the foregoing gas-supplementing structure. The centrifugal compressor gas-supplementing structure includes a annular gas-supplementing passage (6) for introducing supplemented gas into a gas passage (5) of a compressor, and an airflow-guiding assembly is provided in the annular gas-supplementing passage (6). The gas-guiding assembly is used for adjusting a direction of the supplemented gas flowing into the gas passage (5), so that an angle between a direction of the supplemented gas flowing into the gas passage (5) and a direction of an airflow in the gas passage (5) falls within a preset range, and a turbulence loss generated when the two passages of gas merge is avoided to the greatest extent, thereby improving cycle efficiency.Type: GrantFiled: October 13, 2016Date of Patent: January 28, 2020Assignee: GREE ELECTRIC APPLIANCES, INC.

Publication number: 20190310072Abstract: A grating measuring device includes: a light source module (300) for generating two light beams having different frequencies, one of which serves as a measuring beam and the other as a reference beam; a grating (200); and a grating measuring probe (100) including a dual-frequency light reception module, a vertical measurement module, a vertical detection module and a reference detection module. The dual-frequency light reception module is configured to receive the measuring and reference beams, and the vertical measurement module is adapted to project the measuring beam onto the grating (200), collect a zeroth-order diffracted beam resulting from double diffraction occurring at the grating, and feed the zeroth-order diffracted beam to the vertical detection module. The zeroth-order diffracted beam interferes with the reference beam in the vertical detection module, resulting in a vertical interference signal.Type: ApplicationFiled: July 27, 2017Publication date: October 10, 2019Inventors: Ping WU, Zhiping ZHANG

Publication number: 20190086124Abstract: Disclosed is a high-temperature air conditioning device. By changing an arrangement mode of throttle valves, a pressure of refrigerant inside a low-pressure pipeline is made to be lower than a pressure of refrigerant inside a medium-pressure pipeline, thus ensuring that the refrigerant, used for cooling components, inside the low-pressure pipeline has a low pressure, thereby solving a problem in the prior art that a frequency converter, a motor and lubricating oil are not cooled sufficiently or cannot be cooled due to excessively high evaporation pressure.Type: ApplicationFiled: November 20, 2018Publication date: March 21, 2019Inventors: Hua LIU, Hongbo LI, Zhiping ZHANG, Sheng WANG, Dongjun SUN
