Abstract
The utility model relates to an inner structure of an indoor wall unit of an air conditioner with low ventilation air flow noises. The utility model is composed of an air inlet system composed of one air inlet positioned on the upper part of the indoor wall unit, and a cross flow fan in the interior of the air inlet, an evaporation heat exchanger with a sound attenuation component and a group of air outlet flow guide plates. The utility model rearranges the flowing mode of the heat exchange airflow of the indoor wall unit of the air conditioner from an aerodynamic angle. In addition, the structure of a heat exchanger evaporator is changed. The utility model is characterized in that noises caused by the phenomenon of a separated flow, etc. can be greatly reduced; fan energy consumption can be saved in the precondition that a circulating air volume and heat exchange efficiency are not changed.
Description
The utility model relates to the denoising structure that reduces wall hanging machine draft noise in the air conditioner chamber.Particularly 1. becoming the internal structure that conventional draft discharges through the axial-flow fan supercharging through the heat exchange evaporimeter earlier again is that draft is earlier through the axial-flow fan supercharging internal structure that heat exchange is discharged through the heat exchange evaporimeter again.2. evaporating heat exchanger has muffler part, and muffler part is in the inboard of evaporating heat exchanger near axial-flow fan, is pasted with sound-absorbing materials such as mandruka.
The ventilating system of existing conventional air-conditioning device chamber interior walls on-hook roughly is divided into two kinds.First kind is the structure that most producer adopts.Be about to wall hanging machine and be designed to rectangle, heat exchange evaporimeter (1) is placed the place ahead on the wall hanging machine, axial-flow fan (2) is placed the wall hanging machine below, make draft pass through the internal structure that axial-flow fan (2) supercharging is discharged again through heat exchange evaporimeter (1) earlier.As shown in Figure 1.Second kind be wall hanging machine is designed to square, heat exchange evaporimeter (3) is placed wall hanging machine the place ahead, settle major diameter centrifugal fan (4) in heat exchange evaporimeter (3) back, discharge internal structure in the side of the four direction up and down of wall hanging machine through the air-flow of heat exchange.As shown in Figure 2.
The noise of wall hanging machine can be divided into two big classes in the air conditioner chamber: a class is a mechanical noise, and another kind of is the pneumatic noise that air current flow produces.The mechanical noise of wall hanging machine is much smaller than pneumatic noise in the existing air conditioner chamber.Pneumatic noise results from the air-flow whirlpool and separated flow causes the collision of gas micelle.
Present two kinds of ventilating systems all exist deficiency:
The thickness of a, evaporimeter is less than normal, makes the time of staying of air-flow in evaporimeter be as short as a few tens of milliseconds.
For guaranteeing that heat exchange must reduce spacing between the evaporator fin sheet.Spacing is too small between the evaporator fin sheet, makes flow resistance increase.Because the evaporimeter forefront pressure is an atmospheric pressure, this has just further reduced the stream pressure before the fan simultaneously, must increase rotation speed of the fan for this reason, thereby increase noise and energy consumption.
B, fan are wall hanging machine main noise source in the air conditioner chamber, and are directly discharged in the air-conditioner wall hanging machine by the air-flow that fan is discharged, and cause noise bigger than normal.
Patent " air regulator " (96109276.9) changes axial-flow fan into multistage and becomes the diameter axial-flow fan, disperses from noise spectrum, makes noise decrease, and maximum can reduce by 5 decibels.As shown in Figure 3.Except that conventional axial-flow fan, a kind of spiral axial-flow fan appearance that becomes prismatic blade into twist blade is arranged recently, it can disperse noise phase, and noise sound is decreased.But above-mentioned shortcoming does not overcome yet in these two kinds of methods.
The purpose of this utility model is a kind of denoising structure that reduces wall hanging machine draft noise in the air conditioner chamber of structure.The utility model is from aerodynamic angle, the space that makes full use of in the wall hanging machine re-constructs the ventilating duct structure, reduce the generation of separated flow, slow down the existing problem of wall hanging machine in the existing air conditioner chamber, guaranteeing to reduce noise significantly under the constant prerequisite of air-conditioner performance of ventilating, cut down the consumption of energy simultaneously.
The purpose of this utility model is achieved in that air inlet system, an evaporating heat exchanger that has muffler part and one group of exhaust outlet deflector of being made up of the axial-flow fan of an air inlet that is positioned at wall hanging machine top and air inlet inside form.As shown in Figure 4.
At air inlet lip and the inlet channel composition of gas handling system described in the above-mentioned solution (1) for being positioned at wall hanging machine top.
The installation position of the axial-flow fan in above-mentioned solution (2) is the top of wall hanging machine, the bottom of air inlet.
Heat exchange evaporimeter in above-mentioned solution is formed by two parts (3a) with (3b).Wherein (3a) is positioned at the front portion of wall hanging machine, and inter fin space is as usual.(3b) be positioned at the bottom of wall hanging machine, evaporimeter is widened, and inter fin space strengthens, and stamps out spoiler according to aerodynamic design to promote heat exchange and to strengthen rigidity on fin.
Advantage of the present utility model is:
1. becoming the internal structure that conventional draft discharges through the axial-flow fan supercharging through the heat exchange evaporimeter earlier again is that draft is earlier through the axial-flow fan supercharging internal structure that heat exchange is discharged through the heat exchange evaporimeter again.The noise that this structure produces fan can not directly spread out of wall hanging machine.
2. evaporating heat exchanger has muffler part, and muffler part is in the inboard of evaporating heat exchanger near axial-flow fan, is pasted with sound-absorbing materials such as mandruka.This structure has been eliminated most of noise, thereby noise is greatly reduced.

Fig. 2 is the structural representation of second kind of ventilating system of conventional air-conditioning chamber interior walls on-hook;
Fig. 3 is that patent of invention (96109276.9) becomes diameter axial-flow fan schematic diagram;
Fig. 4 is a structural representation of the present utility model.
With reference to accompanying drawing, describe embodiment of the present utility model in detail.
As shown in Figure 4, present embodiment air conditioner refrigerating power is 3500 watts (900mm (wide) * 210mm (thick) * 300mm (height)).Air circulation is per hour 680 cubic metres.
Result of the test:
Measuring position: wall hanging machine in the air conditioner chamber is installed on the 1.8 meters high metopes in ground by national standard.1 meter of 1 meter apart from ground high of measurement point, tool wall are far away.
Measurement environment: semi-anechoic room.
The result: 46 decibel 30 decibels of being reduced to native system of the noise that makes wall hanging machine in this air conditioner chamber with above noise reduction system during from conventional ventilating system, reduced by 16 decibels.Air circulation remains unchanged, and heat exchange efficiency increases.
