The utility model is assembled in the piping system of the evaporator of the indoor unit of an air conditioner to be replaced with a prior throttle device, the small hole throttle decompression principle is combined with the small hole jet silencing principle, thereby the utility model has the advantages of throttling, silencing, filtering, and releasing the pressure fluctuation of the upstream of a pipeline, etc., when the air conditioning operates, on one hand, the throttle function and the effect of capillary pipe throttle are met, on the other hand, injection noise generated by the capillary pipe throttle is eliminated, thereby the purposes of ensuring the throttle as well as realizing the silencing are achieved.
Description
Affiliated technical field
The utility model relates to a kind of air-conditioner, specifically to the improvement of existing air-conditioner structure.
Background technology
At present, the throttling arrangement of idle call mostly is capillary, heating power expansion valve or electromagnetic expanding valve greatly, and its principle mainly is to utilize the local resistance of the tiny mouth of pipe or pipeline and on-way resistance to realize throttling action.Its shortcoming is the rapid increase that diminishing suddenly of the mouth of pipe, pipeline can cause internal refrigeration storage agent flow velocity, thereby jet noise (also claiming jet noise, injection noise) occurs.When these throttling arrangements were disposed at air-conditioner outdoor unit, the problem of noise can ignore or take means such as vibration damping, sound insulation to be reduced, and causes the indoor user discomfort and be unlikely.But when some specific function required throttling arrangement to be installed on indoor set, it is comparatively outstanding that the problem of injection noise then seems.In order to reduce noise, generally adopt measures such as outside wrapping damping block, vibration damping, sound insulation, because aforesaid way is passive noise elimination, DeGrain is difficult to satisfy user's requirement, the low noise requirement when particularly domestic air conditioning moves night.For this reason, the continuous feedback opinion of many users requires to overcome as early as possible above-mentioned defective.
Summary of the invention
The utility model is will solve existing air conditioner room unit and adopt general throttling arrangement the time, the problem that existing injection noise is big.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is: a kind of air-conditioner, it comprises indoor set, empty outer machine and refrigeration system, it is characterized in that: be provided with the throttling muffler on the indoor set pipeline in refrigeration system, this throttling muffler comprises an overcoat, two above screen pack pieces and at least more than one throttling sheet are housed in mantle cavity at least, and above-mentioned screen pack piece and throttling sheet are spaced successively and fix by device for fastening.
Device for fastening is a seal mouth ring, also is equipped with in one to overlap in outer tube, and cover one end has a circle annular bottom surface in this, and in overlapping in screen pack piece and throttling sheet are packed this into successively from the annular bottom surface beginning, its end tightens up by seal mouth ring.
Throttling pore quantity on the adjacent throttling sheet is identical or inequality.
The two ends of overcoat are shaped as tubaeform.
The screen pack piece is a sandwich construction, and its number of plies is 20～100 layers, and filtering the mesh number is 200～500 orders.
Throttle orifice diameter on the throttling sheet is 0.8～25mm.
The utility model good effect that compared with prior art has the following advantages: 1, the utility model is fitted in the piping system of air conditioner room unit evaporimeter, to substitute existing throttling arrangement, it is that orifice restriction decompression principle and micropore jet noise-cancelling theory are combined, make it have throttling, noise reduction, filter, slow down advantages such as pipeline upstream pressure fluctuation, can make air-conditioning when operation, satisfy the throttling function and the effect of capillary-compensated on the one hand, can eliminate the injection noise that capillary-compensated produces on the other hand, thereby reach the purpose that not only can guarantee throttling but also realize noise reduction.2, it have also that compact conformation, cost are low, stable performance, to advantages such as welding process requirement are low.

The specific embodiment
Referring to Fig. 1～Fig. 6, throttling muffler of the present utility model is used mark 20 chief representatives.For the purpose that realizes not only guaranteeing throttling but also eliminating injection noise, design concept of the present utility model is: interior cover 2 is cover in the copper, interior cover 2 one ends have a circle annular bottom surface 7, another compresses end and connects, in the present embodiment, adopt three screen pack pieces 3 and two throttling sheets 4,5 altogether, above-mentioned screen pack piece 3 is spaced in annular bottom surface 7 begins to pack into successively this with throttling sheet 4 and overlaps in 2, compressing end adopts interference fit to be pressed into to seal copper ring 6, be tight impaction state with screen pack piece 3 and the throttling sheet 4,5 that guarantees cover 2 inside in the copper.Then, interior cover 2 is squeezed into overcoat 1 inner chamber, again the size that needs is arrived in overcoat 1 two ends reducing, it is tubaeform that it is become.
Screen pack piece 3 is a sandwich construction, and its number of plies is 20～100 layers, and filtering the mesh number is 200～500 orders, and in the present embodiment, screen pack piece 3 adopts ceramic material to make, and its number of plies is 60 layers, and the order number is 300 orders.Certainly, screen pack piece 3 also can be made of copper.
Requirement for throttling, owing to be to utilize orifice restriction decompression principle (comprising the throttle orifice on screen pack piece mesh and the throttling copper sheet), therefore, can adjust realization by the diameter of adjusting inside and outside cover 2,1, order number, the number of plies, the diameter of throttle orifice, the quantity of throttle orifice and the quantity of throttling sheet of screen pack piece 3.
For the requirement of noise reduction, because utilization is the principle that micropore jet is eliminated the noise, therefore, multiple filtration net piece 3 formed micropore sizes will influence the sound-deadening and noise-reducing effect.So can be in conjunction with the requirement of flow, order number, the number of plies of adjusting screen pack realize sound-deadening and noise-reducing effect preferably.
Referring to Fig. 7, the refrigeration system of air-conditioner is represented with mark 23.This noise reduction flow controller 20 is fitted in the indoor set pipeline of air-conditioner refrigerating system 23, to replace existing throttling arrangement, capillary 12 as dotted line position among Fig. 7, can make air-conditioner when operation, satisfy the throttling function and the effect of capillary-compensated on the one hand, can eliminate the injection noise that capillary-compensated produces on the other hand, thereby reach the purpose that not only can guarantee throttling but also realize noise reduction.
The foregoing description only supplies the usefulness of explanation the utility model, and is not to be to restriction of the present utility model, on the basis of the foregoing description, can also make various variations or remodeling, and not exceed essential scope of the present utility model.
