Abstract
The utility model discloses an exhaust port device of an air conditioning unit. By the aid of the exhaust port device, the problem of loud noise of an existing air conditioning unit can be effectively solved. The exhaust port device of the air conditioning unit comprises an exhaust pipe, an elbow pipe and a noise reduction device. The elbow pipe is connected with the exhaust pipe, the noise reduction device sprays noise reduction liquid into the exhaust pipe, and spray openings of the noise reduction device is arranged on the exhaust pipe on an upstream portion of the elbow pipe. The exhaust port device has the advantages that the noise reduction liquid is sprayed into the exhaust pipe on the upstream portion of the elbow pipe and is vaporized in the exhaust pipe to form air cushions, so that impact of airflow to a shell is reduced, and noise is reduced; the influence on the efficiency of the air conditioning unit is prevented, and the exhaust port device is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of air-conditioning unit, specifically, relates to air-conditioning unit exhaust port device.
Background technology
Noise when air-conditioning unit, particularly central air-conditioning move is larger.When bringing a home from home, these equipment also produced noise pollution, the user has to these equipment is arranged on the special-purpose equipment regions such as basement, but operator and white collar worker for equipment, its too high noise is still unavoidable, if often in this high-decibel environment, very irritable, irritability that the people can become.For attended operation personnel's physical and mental health and working environment, we solve the noise problem of air-conditioning unit as early as possible an urgent demand.
The noise of air-conditioning unit is mainly derived from that high speed gaseous refrigerant gas shock air-conditioning duct causes, and wherein air velocity is the fastest, impact and the most significantly surely belong to the exhaust outlet bend loss, so this place is also the generation the most serious place of noise.At present, not yet there is effective method to reduce the high speed refrigerant gas stream and impact the method that blast pipe produces noise, can only be by the construction soundproof room or at pipeline place parcel Sound-proof material.Wherein set up soundproof room and involve great expense, floor space is large, uneconomical; Adopt the Sound-proof material cost lower, but DeGrain.
The utility model content
The purpose of this utility model is to provide air-conditioning unit exhaust port device, can effectively solve the existing large problem of air-conditioning unit noise.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: air-conditioning unit exhaust apparatus, comprise blast pipe and the bend pipe that is connected blast pipe, also comprise that the mouth spray of described denoising device is located on the blast pipe of bend pipe upstream to spraying the denoising device of noise reduction liquid in blast pipe.
Preferably, described denoising device comprises the condenser of storing refrigerant, the feed pipe that refrigerant in condenser is transferred to blast pipe, and feed pipe communicates with condenser by stop valve, also is provided with electromagnetic pump on described feed pipe; By electromagnetic pump, refrigerant is squeezed in blast pipe to simple and practical denoising device.
Preferably, described stop valve is fixed on the bottom of condenser; Be convenient to liquid refrigerant is extracted out.
Preferably, described feed pipe is fixed on condenser by pipeline support; Prevent that feed pipe is at work because vibration gets loose.
Preferably, be evenly equipped with at least two mouth sprays in same cross section on described blast pipe; Spray refrigerant in the supply and exhaust pipe uniformly, make the refrigerant of gaseous state can form uniform air cushion.
Compared with prior art, the utility model has the advantages that: by spraying noise reduction liquid in the blast pipe to the bend pipe upstream, noise reduction liquid is vaporized in blast pipe and form air cushion, reduce the impact of air-flow to shell, thereby reduction noise, and can the efficiency of air-conditioning unit not exerted an influence, simple in structure, with low cost.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model air-conditioning unit exhaust port device.
The specific embodiment
Consulting Fig. 1 is the embodiment of the utility model air-conditioning unit exhaust port device, air-conditioning unit exhaust apparatus, comprise blast pipe 6 and the bend pipe 7 that is connected blast pipe 6, also comprise to the denoising device of the interior injection noise reduction of blast pipe 6 liquid, the mouth spray of described denoising device is located on the blast pipe 6 of bend pipe 7 upstreams, on described blast pipe 6, in same cross section, is evenly equipped with at least two mouth sprays.
Described denoising device comprises the condenser 1 of storing refrigerant, the feed pipe 3 that the interior refrigerant of condenser 1 is transferred to blast pipe 6, feed pipe 3 communicates with condenser 1 by the stop valve 2 that is fixed on condenser 1 bottom, also be provided with electromagnetic pump 4 on described feed pipe 3, described feed pipe 3 is fixed on condenser 1 by pipeline support 5.
During work, first open stop valve 2, make the liquid refrigerants in condenser 1 enter feed pipe 3, then by electromagnetic pump 4, the liquid refrigerants in pipeline is pumped in blast pipe 6, enter the liquid refrigerants vaporization immediately under hot environment in blast pipe 6, form similar air cushion structure at the tube wall place, thereby lower the high speed gaseous coolant, impact the noise that shell produces, can make noise decline 4-5 decibel.In the hydrojet noise reduction process, after the liquid refrigerants vaporization of ejection, except impacting blast pipe 6 by buffering exhaust implication stream, thereby the refrigerant temperature of also cooling exhaust outlet has increased the condensation efficiency of subsequent condensation device 1, thereby this hydrojet denoising structure can not impact the efficiency of air-conditioning unit.
The foregoing is only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the scope of the claims of the present utility model.
