Abstract
The utility model relates to a denoising structure for an air conditioner. The denoising structure comprises an electronic expansion valve and a two-way check valve, wherein a capillary tube and an expansion-type silencer are arranged between the electronic expansion valve and the two-way check valve; the capillary tube is connected in series with the expansion-type silencer; one end of the capillary tube is connected with one end of the electronic expansion valve; and one end of the expansion-type silencer is connected with the two-way check valve. The capillary tube and the expansion-type silencer are additionally arranged between the electronic expansion valve and the two-way check valve, so that when coolant noise generated at the electronic expansion valve is transferred to the capillary tube, because of the sharp reduction in flow area, the forward transfer energy of coolant sound is reduced due to sound wave reflection. Therefore, the coolant noise is reduced effectively. The expansion-type silencer arranged between the capillary tube and the two-way check valve can effectively eliminate the coolant noise.
Description
Technical field
The utility model relates to a kind of air-conditioning, more particularly, relates to a kind of idle call noise reducing mechanism and is provided with the air-conditioning of this noise reducing mechanism.
Background technology
Convertible frequency air-conditioner is when the running refrigerating pattern, and is different according to the indoor and outdoor operating mode, and compressor rotary speed is different, and it is different that refrigerant flows through the heat exchanger degree of supercooling of back when flowing out that cool.When the refrigerant degree of supercooling is enough big, be liquid refrigerants during outflow heat exchanger, can not produce unusual refrigerant sound when flowing through electric expansion valve; When the refrigerant degree of supercooling is too small; It during outflow heat exchanger gas-liquid two-phase attitude refrigerant; After gas-liquid two-phase state refrigerant gets into electric expansion valve via pipeline, change, vibration generation refrigerant sound takes place because of liquid refrigerants and gaseous state refrigerant flow rate difference cause the throttle mechanism crushing at electric expansion valve place; The refrigerant sound that produces imports into indoor via pipe-line system, produce room noise.
The utility model content
To the one or more problems that exist in the correlation technique, the purpose of the utility model is to provide a kind of idle call denoising structure, can eliminate the coolant noise that produces at the electric expansion valve place.
For realizing above-mentioned purpose, an aspect according to the utility model provides a kind of idle call denoising structure; Comprise electric expansion valve and two logical stop valves; Comprise electric expansion valve and two logical stop valves, between electric expansion valve and two logical stop valves, be provided with capillary and intumescent muffler, capillary and intumescent muffler are connected in series; An end capillaceous is connected with an end of electric expansion valve, and an end of intumescent muffler is connected with two logical stop valves.
The utility model also provides a kind of air-conditioning, comprises above-mentioned denoising structure.
Preferably, air-conditioning also comprises the off-premises station heat exchanger, and the off-premises station heat exchanger is connected with the other end of electric expansion valve.
Than prior art, the beneficial effect of the utility model is:
1. between heat exchanger and expansion valve, increase capillary, the coolant noise that produces when the electric expansion valve place is during through capillary, because of circulation area is sharply dwindled, acoustic reflection make the refrigerant sound forward Propagation of Energy reduce, effectively reduce coolant noise;
2. the intumescent muffler is set between capillary and stop valve, can effectively eliminates coolant noise.
Description of drawings
Above-mentioned and/or additional aspect of the utility model and advantage are from obviously with easily understanding becoming the description of embodiment below in conjunction with accompanying drawing, wherein:
Fig. 1 is the sketch map according to the denoising structure of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described.
As shown in Figure 1; Electric expansion valve 2 one ends are connected with heat exchanger of air conditioner outdoor unit 1; The other end is connected with an end of capillary 3; The other end of capillary 3 is connected with intumescent muffler 4, and intumescent muffler 4 is connected with two logical stop valves 5 again, and promptly off-premises station heat exchanger 1, electric expansion valve 2, capillary 3, intumescent muffler 4, two logical stop valves 5 are connected in series successively.
Wherein capillary 3 is main silencing apparatus, and intumescent muffler 4 is auxiliary silencing apparatus.The coolant noise that in electric expansion valve 2, produces is propagated forward through connecting line, during through capillary 3, because of circulation area is sharply dwindled, acoustic reflection make the refrigerant sound forward Propagation of Energy reduce.Coolant noise is effectively slackened through capillary 3; Remaining coolant noise still can propagate into intumescent muffler 4 forward through connecting line; Sound wave is in acoustic characteristic sudden change place; Sound wave can produce reflection, and this moment, a part of sound wave reflected back to Sounnd source direction, and only remaining minimum part continues to propagate forward.Through main silencing apparatus capillary 3 and auxiliary silencing apparatus intumescent muffler 4, eliminated the coolant noise that electric expansion valve 2 places produce basically.
The utility model also provides a kind of air-conditioning, comprises above-mentioned denoising structure.
The utility model is through increasing capillary 3 between off-premises station heat exchanger 1 and expansion valve; When the coolant noise that produces when electric expansion valve 2 places passes through capillary 3; Because of circulation area is sharply dwindled, acoustic reflection make the refrigerant sound forward Propagation of Energy reduce, effectively reduce coolant noise; Through between capillary 3 and two logical stop valves 5, intumescent muffler 4 being set, can effectively eliminate coolant noise.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
