Abstract
The utility model relates to a noise reducing ring for indoor units of a multiple linked air conditioner set, belonging to the technical field of the air-conditioning industry. The utility model can reach the effect of noise reducing and sound quality improving under the condition that the volume of the indoor machine is not enlarged and the cost is not increased. A straight pipe is winded in circle shape and then connected between an electronic expansion valve and a liquid separator, the ring is at least one turn, and the straight pipe is helical shape integrally after winded in circle shape. The utility model has the advantages of simple structure, easy producing, low cost and easy assembling, and achieves the effect of noise reducing and sound quality improving of the air-conditioners.
Description
Technical field:
The utility model is a kind of noise reduction ring of indoor apparatus of air conditioner, particularly relates to a kind of noise reduction ring of combined air conditioners unit indoor set, belongs to air conditioner industry.
Background technology:
The combined air conditioners unit is a ultra-modem technology product in the present air-conditioning, has very high scientific and technological content, and market and wide.But, multi-joint machine provides cold-producing medium to many indoor sets simultaneously because being an off-premises station, so the flow velocity of system's inner refrigerant and changes in flow rate are very big, the cold-producing medium gas, liquid mixture that causes unsteady flow amount, flow velocity produces various noises during by closure member such as electric expansion valve, liquid-dividing head, capillaries, and the size of noise just the consumer choose a key index of air-conditioning.In order to satisfy consumer's needs, existing air-conditioner generally takes following two kinds of methods to reduce noise: one, closure member such as electric expansion valve are wrapped acoustical cotton and be contained in separately in the box, be placed on by the indoor set.Do neither attractive in appearancely like this, project installation is also inconvenient.Two, the indoor set volume is strengthened, make the gas that comes out from electric expansion valve, cold-producing medium that liquid mixes to the flow process long enough the liquid-dividing head, make the flow velocity of cold-producing medium tend towards stability, gas, liquid mix as far as possible evenly as far as possible, thereby lower the noise that multi-online indoor machine produces.Increased cost again but the increasing of indoor set volume is neither attractive in appearance, and the consumer thinks that its floor space is too big, wasting space.
Summary of the invention
The purpose of this utility model is to provide a kind of noise reduction ring of indoor apparatus of air conditioner, is not strengthening the indoor set volume and is not increasing under the condition of cost, reaches the effect that reduces noise, improves tonequality.
The purpose of this utility model is achieved in that the noise reduction ring of indoor apparatus of air conditioner, by being connected between electric expansion valve and the knockout after the straight tube coiled annular.
Its second architectural feature is integral body shape in the shape of a spiral after the described pipe coiled ring-type.
The caliber that its 3rd architectural feature is described pipe is at φ 6---between the φ 12.
The ring that its 4th architectural feature is described pipe coiled is an annulus, and the diameter of described annulus is at φ 40---between the φ 100.
The material that its 5th architectural feature is described body is copper preferably.
Its 6th architectural feature is that described ring is at least a circle.
The utility model has the advantages that: (one), simple in structure, easily manufactured, with low cost; (2), assembling easily, can play the effect that reduces the air-conditioning noise, improves tonequality.After adopting this noise reduction ring, can reduce level of noise 2-3dB, can eliminate because the caused high-frequency air flow sound of variation and the low frequency liquid stream sound of flow rate.
Description of drawings:
Accompanying drawing 1, front view of the present utility model;
Accompanying drawing 2, upward view of the present utility model.
The specific embodiment:
Present combined air conditioners unit is in order accurately to control the flow that enters each indoor set cold-producing medium, electric expansion valve, the first-class closure member of separatory all are placed in the indoor set, when off-premises station of multi-joint machine simultaneously when many indoor sets provide cold-producing medium, the combined air conditioners unit is because the difference of each indoor set cooling and heating load demand, cold-producing medium flow velocity, the flow of compressor output all change at any time, when gas, the liquid mixture of unsteady flow speed, flow pass through in the pipeline of prior art, will produce noise, and lower tone; How when reducing the multi-online indoor machine noise, electric expansion valve, the first-class closure member of separatory can be placed in the multi-joint indoor set, don't you increase the volume of indoor set again? the inventor is through the research of convection cell mechanics and noise and repeatedly experiment back discovery, if gas, liquid mixture by closure member such as electric expansion valve, liquid-dividing head, capillaries flow mild more, flowing velocity is slow more, and the noise that then sends is more little and tonequality is better.Because reasons such as attractive in appearance and cost though the inventor can not directly change the length of pipeline, can change the shape of pipeline.So the inventor has expected the method for pipe coiled annular, because pipe has curved ring-type, so as long as the inventor is many around several circles, with regard to the indirect length that has increased pipeline in limited space.Because will certainly be subjected to the obstruction of pipeline during the liquid flow in the middle of the variation of the growth of pipeline and shape, pipeline, just can play steadily and the effect that slows down gas, flow velocity.Because gas, flow velocity steadily and slow down, noise has just diminished naturally.Again because of the pipeline smaller volume of doing circlewise, the inventor can be relieved all be placed in the indoor set electric expansion valve of any one-to-one indoor air conditioner, the first-class closure member of separatory, and not worrying that it can send very big noise, the inventor just need not to add in addition a throttle part box like this.
In the utility model, the noise reduction ring of indoor apparatus of air conditioner is by being connected between electric expansion valve and the knockout after the straight tube coiled annular; Integral body shape in the shape of a spiral after the described pipe coiled ring-type.As shown in Figure 1, 2, the employing diameter is that the copper pipe 1 of d is bent into the copper ring 2 that diameter is D, and the d size of the diameter D of annulus and the diameter of copper pipe is to learn final definite by the size of indoor unit capability and hydrodynamics, noise; The diameter D of described annulus and described copper pipe diameter d roughly are inversely proportional to.The caliber of described pipe is generally at φ 6---between the φ 12; The diameter of described annulus is at φ 40---between the φ 100.
According to different situations, the utility model can also be made turnover tube angulation difference and the copper pipe caliber similar structures different with the pitch of the laps size.Ring can be oval, square etc. as described.
