Abstract

The utility model relates to the field of air conditioning unit equipment, and relates to a novel inspiration and exhausting device of a compressor used for an air conditioner. The structure is as follows: an exhaust port is positioned on the upper part of the compressor, an exhaust L-shaped coppering iron tube is welded and fixed on the exhaust port, and an exhaust U-shaped coppering iron tube is welded and fixed at the tail end of the exhaust L-shaped coppering iron tube; an exhaust copper tube is welded and fixed at the tail end of the exhaust U-shaped coppering iron tube, and an air suction inlet is positioned at the lower part of the compressor; and an inspiration coppering iron tube is welded and fixed on the air suction inlet, and the inspiration copper tube is welded and fixed at the tail end of the inspiration coppering iron tube. For the novel inspiration and exhausting device, the structure is simple, and the irregular bending shape is adopted, as the position of the compressor is fixed, the stress can be effectively reduced due to the bending characteristic property of an exhaust pipe; and in addition, the anti-seismic stress value of the coppering iron tube is better than that of the copper tube, so that stress of a tubing connected with a pipe port of the compressor is less than rupture stress while the start-up, running and stop of the compressor are guaranteed.

Description

A kind of air-conditioning is with the air-breathing and venting gas appliance of compressor

Technical field

The utility model relates to air conditioner group equipment field, particularly a kind of novel air-breathing and venting gas appliance that is applicable to the air conditioner use of high-power scroll compressor.

Background technique

At present; The compressor of a lot of high-power air conditioners (for example 10HP) all uses two little compressor parallels on the market; The fraction horsepower compressor is because of the reason of himself design aspect; Start at air conditioner, turn round, when stopping vibrations (natural frequency) less, the suction tracheae that therefore is attached thereto adopts copper pipe to get final product.If but use two compressors to be the low-pressure cavity compressor parallel connection; Then need between two compressors, add an oil balance tube; Because getting back to the lubricants capacity of every compressor not necessarily equates; The oil of the more compressor of oil return is flowed in the less compressor of oil return through oil balance tube, and when the design oil balance tube, also will guarantee certain camber, the piping stress of angle to prevent compressor start, to turn round, produce when stopping.

For to the extra high machine of required precision, possibly also increase the next concrete control of an oil level perceptron on the compressor therein.So; Use the machine of two little compressor parallels; Singly on design, test, cost aspect is not best choice; If but directly use the compressor of high-power, will cause compressor to surpass the stress range that outlet pipe and sucking pipe can bear at the piping stress that starts, turns round, produces when stopping, causing the damage of breaking of outlet pipe and sucking pipe.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned not enough problem; Air-breathing and the venting gas appliance of a kind of air-conditioning with compressor is provided; Simple in structure, row, sucking pipe use the combination connecting mode of copper facing iron pipe and copper pipe, can avoid the damage of breaking of copper pipe stress; Be applicable to the high-power compressor, safe and reliable.

The technological scheme that the utility model adopts is: a kind of air-conditioning is with the air-breathing and venting gas appliance of compressor; Comprise outlet pipe and sucking pipe; Outlet pipe is made up of exhaust L type copper facing iron pipe, exhaust U type copper facing iron pipe and exhaust copper pipe; Sucking pipe is made up of air-breathing copper facing iron pipe and air-breathing copper pipe, and relief opening is positioned at the top of scroll compressor; Exhaust L type copper facing iron pipe is fixedly welded on the relief opening, and exhaust U type copper facing iron pipe is fixedly welded on exhaust L type copper facing iron pipe tail end, and the exhaust copper pipe is fixedly welded on exhaust U type copper facing iron pipe tail end; Intakeport is positioned at the bottom of scroll compressor; Air-breathing copper facing iron pipe is fixedly welded on the intakeport, and air-breathing copper pipe is fixedly welded on air-breathing copper facing iron pipe tail end.

Said exhaust copper pipe is irregular curved shape, and crooked direction is a clockwise direction.

The angle that forms when the axis of said exhaust copper pipe and exhaust outlet of compressor is space crossed is greater than 90 degree.

The utility model is simple in structure; After adopting above-mentioned irregular curved shape; Because the position of compressor is fixed, the characteristic performance that outlet pipe is crooked effectively reduces stress, and the antidetonation stress value of copper facing iron pipe is good than copper pipe in addition; Can guarantee at compressor start, turn round, when stopping, the piping stress that is connected in the compressor mouth of pipe is less than bursting stress.

Embodiment

Specify the utility model below in conjunction with accompanying drawing, but the utility model is not limited to specific embodiment.

Shown in accompanying drawing 1, a kind of air-conditioning of the utility model comprises outlet pipe and sucking pipe with the air-breathing and venting gas appliance of compressor; Outlet pipe is by exhaust L type copper facing iron pipe 1; Exhaust U type copper facing iron pipe 2 constitutes with exhaust copper pipe 3, and exhaust copper pipe 3 is irregular curved shape, and crooked direction is a clockwise direction; Sucking pipe is made up of with air-breathing copper pipe 5 air-breathing copper facing iron pipe 4, and relief opening 6 is positioned at the top of scroll compressor 7; Exhaust L type copper facing iron pipe 1 is fixedly welded on the relief opening 6; Exhaust U type copper facing iron pipe 2 is fixedly welded on exhaust L type copper facing iron pipe 1 tail end; Exhaust copper pipe 3 is fixedly welded on exhaust U type copper facing iron pipe 2 tail ends, and the angle that forms when the axis of exhaust copper pipe 3 and exhaust outlet of compressor 6 is space crossed is 105 degree; Intakeport 8 is positioned at the bottom of scroll compressor 7; Air-breathing copper facing iron pipe 4 is fixedly welded on the intakeport, and air-breathing copper pipe 5 is fixedly welded on air-breathing copper facing iron pipe 4 tail ends.

Scroll is clockwise sense of rotation during according to compressor start, and the axis angle of outlet pipe and exhaust outlet of compressor is greater than 90 degree, so also want clockwise direction, excessive to prevent the compressor start transient vibration, outlet pipe directly breaks.During operation of air conditioner, compressor start moment, vibrations are maximum and compressor is inhaled, relief opening is direct-connected is the copper facing iron pipe, and its antidetonation stress value is bigger than copper pipe.Copper pipe after the iron pipe, owing to irregular curved shape is arranged and then effectively reduce the stress of pipe, therefore such circuit design can guarantee air conditioner unlikely pipeline stress and breaking in long-term.

The stress value of the suction of warp test compressor, outlet pipe each point is like following single ㎏/㎜ ²):

Piping stress when this compressor suction, exhaust pipe device moved, turn round and stop in the compressor beginning satisfies the normal requirement of using less than bursting stress.
