Horizontal Compressor With Integrated Accumulator Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation area of conventional horizontal compressors is increased due to the separate placement of the accumulator outside the compressor, limiting the reduction in size of commercial refrigerators.
Innovation Solution
The accumulator is integrated within the case of the horizontal compressor, utilizing a high and low-pressure separating plate to divide the internal space, an internal suction pipe with a connecting and stand pipe configuration, and a screen to separate liquid refrigerant and oil, enhancing heat exchange and reducing installation area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the accumulator is disposed outside the horizontal compressor, then the accumulator can effectively separate liquid refrigerant and oil, but the installation area of the horizontal compressor increases
Solution Approach 1:
The patent integrates the accumulator function within the horizontal compressor by dividing the compressor case into a high-pressure chamber and a low-pressure chamber using a high-low pressure separating plate. The low-pressure chamber serves as the accumulator, eliminating the need for a separate external accumulator and thereby reducing the overall installation area while maintaining liquid refrigerant separation capability.
2Area of stationary object
If the accumulator is integrated within the compressor case, then the installation area is reduced, but the heat exchange efficiency may be affected
Solution Approach 1:
The compressor case is segmented into distinct high-pressure and low-pressure chambers using a high-low pressure separating plate. This segmentation allows the low-pressure chamber to function as an accumulator with sufficient volume for effective heat exchange and liquid refrigerant separation, while the overall integrated design reduces installation area. The separating plate ensures proper thermal isolation and pressure differential maintenance.

AI summary
A horizontal compressor includes a case; a high and low pressure separating plate dividing an inner space of the case into a high-pressure chamber and a low-pressure chamber; a compressor in the high-pressure chamber configured to be operated by a motor to compress refrigerant; a suction pipe in the case to communicate with the low-pressure chamber and through which the refrigerant is sucked; and an internal suction pipe to pass through the high and low pressure separating plate, one end of the internal suction pipe connected to the compressor and another end of the internal suction pipe to communicate with the low-pressure chamber so that the refrigerant in the low-pressure chamber flows into the compressor, wherein the internal suction pipe includes a connecting pipe adjacent to a lower surface of the case parallel to a central axis of the case.
