Description

Technical Field

[0001] The utility model discloses a refrigeration system with a copper tube connection structure, in particular to a refrigeration system with an anti-vibration copper tube connection structure, belonging to the technical field of refrigeration systems. Background Art

[0002] In the air conditioning system, the reasonable arrangement of the series of pipelines and good workmanship play an important role in the performance, vibration and noise of the unit. Unreasonable system pipeline design not only increases the resistance to the flow of refrigerant, but also causes large vibrations and even leads to cracking or breaking of the system pipelines.

[0003] like Figure 3 As shown, in the existing air conditioning refrigeration system, the condenser and the compressor are connected to the compressor exhaust through an exhaust pipe, and the exhaust pipe is generally changed by a right angle with a certain radius R to change the direction of the copper pipe. A better design may add a "U" bend to reduce the vibration of the exhaust pipe. However, it cannot fundamentally change the problem of large vibration and high noise of the exhaust pipe, and there is also the problem of large refrigerant flow resistance. Utility Model Content

[0004] The purpose of the utility model is to provide a refrigeration system with an anti-vibration copper tube connection structure in view of the defects of large exhaust pipe vibration, high noise and large refrigerant flow resistance in the prior art of the refrigeration system with the above-mentioned copper tube connection structure, which can achieve the goals of small exhaust pipe vibration, low noise and small refrigerant flow resistance.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a refrigeration system with an anti-vibration copper tube connection structure, including an anti-vibration welded sheet metal frame and a compressor, an exhaust pipe, a condenser, a condensate pipe, an evaporator and an air intake pipe arranged in the anti-vibration welded sheet metal frame, the condenser is connected to the compressor through an exhaust pipe, and the exhaust pipe is arranged at the exhaust outlet of the compressor; the evaporator is connected to the condenser through a condensate pipe, and the compressor is connected to the evaporator through an air intake pipe; the refrigerant flows from the compressor to the condenser and the evaporator in sequence, and then returns to the compressor to form a refrigeration system;

[0006] The exhaust pipe is an anti-vibration copper pipe, and the design of the anti-vibration copper pipe is as follows: according to the flow direction of the refrigerant, a large arc of "360°+α" or "720°+α" is added to guide the flow of the refrigerant; this can reduce the flow resistance of the refrigerant, and more importantly, effectively reduce the vibration of the system exhaust, fundamentally solving the problem of the exhaust pipe being cracked or broken due to excessive vibration; the outer periphery of the anti-vibration copper pipe is sleeved with a heat-resistant vibration-damping sleeve before welding, which can more effectively reduce vibration and avoid the problem of friction between copper pipes due to vibration;

[0007] α is the central angle of the arc between the two ends of the heat-resistant vibration-damping sleeve, which is 90° to 180°.

[0008] The large arc is "360°+α", when α is 160°, the design of the anti-vibration copper tube is: according to the flow direction of the refrigerant, a large arc of "360°+160°=520°" is added to guide the flow of the refrigerant.

[0009] The large arc is "720°+α", when α is 120°, the design of the anti-vibration copper tube is: according to the flow direction of the refrigerant, a large arc of "720°+120=840°" is added to guide the flow of the refrigerant.

[0010] A vibration damping seat is arranged below the compressor, and a vibration damping pad is arranged below the vibration damping seat.

[0011] Compared with the prior art, the utility model has the following beneficial effects: in the air conditioning refrigeration system, a new type of anti-vibration copper pipe connection structure is designed, which plays a certain role in reducing the compressor exhaust vibration and noise. Reasonable system pipeline routing reduces the resistance of refrigerant flow, improves the performance of the unit, and reduces the noise of the unit.

[0012] A vibration-proof copper pipe connection structure is to add a large arc of more than 360° or more than 720° at the exhaust outlet of the compressor according to the flow direction of the refrigerant to guide the flow of the refrigerant. This can reduce the resistance to the flow of the refrigerant, and more importantly, effectively reduce the vibration of the exhaust system, fundamentally solving the problem of cracking or breaking of the exhaust pipe due to excessive vibration. At the same time, the exhaust pipe is connected in series with a heat-resistant vibration-damping sleeve before welding, which can more effectively reduce vibration and avoid friction between copper pipes due to vibration.
