Household air conditioner flow regulation pipe

Abstract

The invention relates to a flow regulating tube for a household air conditioner, which comprises a motion block (3) arranged in a metallic conduit (4) and two fixed blocks (1), (2) having a proper distance apart from each other which are fixed on the inner wall of the metallic conduit. The motion block can freely slide between the two fixed blocks; the motion block has a capillary ventage (7) running through an axle center; fixed block capillary ventages (6) corresponding to the motion block capillary ventage are arranged on the fixed blocks; a plurality of circumference ventages (5) are arranged on the fixed blocks; the inside diameter of the metallic conduit is set as 5 to 25 mm, the length is set as 20 to 300 mm, the pore diameters of the fixed block capillary ventages and the motion block capillary ventage are set as 0.5 to 2.5 mm, the total length of a passage of the motion block capillary ventage and the passages of the fixed block capillary ventages is set as 5 to 200 mm, and the pore diameters of the circumference ventages are set as 1 to 4 mm; filters (8) are arranged at the other ends of the fixed blocks; and the filters are embedded into the inner wall of a metallic conduit port; a plurality of ring grooves (11) are arranged on the outside diameters of the fixed blocks. The invention not only can obviously reduce the manufacturing cost, but also can decrease the freezing medium and energy consumption; in addition, the structure is simple, and the energy efficiency ratio is high.

Description

technical field [0001] The invention relates to the technical field of household air conditioners, and specifically refers to a household air conditioner flow regulating tube with an optimal combined structural size that can significantly reduce the best energy efficiency ratio of refrigerant and energy consumption. Background technique [0002] Existing home air conditioner flow regulating tubes have many structural forms, among which Chinese patent No. 200420090859.8 "A Throttle Tube for Air Conditioning Refrigeration" includes a cylindrical moving block and a fixed block installed in the pipeline, wherein the moving block Both ends are convex conical surfaces, and a small hole runs through the axis of the moving block, which is a refrigerant channel. The moving block can slide freely in the cavity formed by the fixed block and the pipe wall; the fixed block consists of two pieces , separated by an appropriate distance and respectively fixed on the inner wall of the pipeli...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned "A Kind of Air-conditioning and Refrigeration Throttle Tube" does not provide the optimal combined structural size of the fixed block, moving block and capillary hole diameter and matching length, so it is difficult to obtain a significant reduction in refrigerant and energy consumption. The best energy efficiency ratio effect of consumption; secondly, there is no filter in the refrigerant channel of the fixed block to affect its cooling energy efficiency; thirdly, there is no ring groove between the outer diameter of the fixed block and the inner wall of the metal tube, and the fluid is easy to flow from the fixed block Leakage between the outer diameter of the block and the inner wall of the metal tube, thereby reducing the economy of the refrigeration system
