Upward-inlet-type air suction distributor for compressor condensing unit

Abstract

The invention relates to an upward-inlet-type air suction distributor for a compressor condensing unit. The upward-inlet-type air suction distributor comprises an air suction collecting pipe, branch pipes and an air return main pipe. The air return main pipe is installed on the upper portion of the air suction collecting pipe in a vertical communicating mode, and the multiple branch pipes are installed on the positions, on the left side and the right side of the air return main pipe, of the air suction collecting pipe at intervals in a vertical communicating mode; and according to the structure of the air return main pipe, a plurality of air outlet long holes are evenly manufactured in the side wall of the bottom end of the air return main pipe embedded in the air suction collecting pipe,and a circular blocking plate with the same diameter as the air return main pipe is fixedly installed at the bottom end of the air return main pipe. In the upward-inlet-type air suction distributor, the air outlet holes of the air return main pipe adopt a side wall air outlet mode, oil at the bottom of the air suction collecting pipe is prevented from being stamped due to the large pressure, and the normal oil surface inside the air suction collecting pipe is ensured to prevent fluctuation of the oil surface, so that the oil is prevented from entering the branch pipes; and the upward-inlet-type air suction distributor is simple in structure, scientific and reasonable in design, ingenious in concept, easy to achieve and low in cost and has wide application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to an upward suction distributor of a condensing unit of a compressor. Background technique [0002] The compressor sucks the lower-pressure working medium vapor from the evaporator, raises its pressure, and then sends it to the condenser, where it is condensed into a higher-pressure liquid, which becomes a higher-pressure liquid after being throttled by the throttle valve. After the low-pressure liquid is sent to the evaporator, it absorbs heat and evaporates in the evaporator to become a steam with a lower pressure, thereby completing the refrigeration cycle. [0003] The compressor condensing unit includes a suction header 1 and a return air header 3, the return air header is vertically installed on the upper part of the suction header, such as figure 1 As shown, the suction headers on the left and right sides of the air return main pipe are vertically spaced and communicate...

AI Technical Summary

Problems solved by technology

[0004] The problem existing in the above structure is: because the gas is discharged from the bottom end of the air return main pipe, and the gas pressure is relatively high, the oil at the bottom of the suction manifold is blown to both sides, making it easy to enter the bottom of the branch pipe at both ends. Oil, thus affecting the quality of the compressor
