Description
Technical field
The utility model relates to a kind of air-conditioner, more specifically to a kind of efficient, low noise sphere air-conditioner that does not have the air channel.
Background technology
Efficiently, low noise is the two principal themes of air-conditioner forever.High-efficiency air-condition requires air-conditioner that the highest heat exchange efficiency will be arranged, the size of the height of heat exchange efficiency and air quantity and two devices has the relation of direct ratio, and the increase of air quantity increases pneumatic noise, and evaporimeter increases cost and will increase, and is conflicting often between them; Airflow noise is the main source of sound of indoor set noise, and fan and air channel produce the main root that the eddy current noise is an airflow noise.The air duct type indoor machine structure of air-out under the air intake before traditional separated wall hanging type air conditioner mostly is, this structure existing questions is: 1) heat exchange efficiency is lower, and at present, adopting the general heat exchange efficiency of separated wall hanging type air conditioner of this structure is about 67%.Because of heat exchange efficiency is lower, in order to reach the rated performance of air-conditioner, adopts the method for sacrificing cost and increasing evaporimeter usually, or sacrifice the noise index and improve the method for rotation speed of the fan.2) the air channel design is complicated, and noise is difficult to reduce.The mode that the separated wall hanging type air conditioner noise of this structure produces shown in accompanying drawing three mainly contains following several: 1. the instability of air inlet air-flow flow and impeller between the noise that interaction produced.Shown in accompanying drawing three, in fan inside, not only interaction produces noise with fan blade in the high pressure group that is caused by rectifier, and, because the effect of high pressure group has influenced the dynamic balancing of fan, the running noise of fan self is strengthened.Institute's target counter-pressure district has not only influenced heat exchange efficiency among the figure, and has produced the bigger non-stationary flow nip of taking offence, strengthened and impeller between the noise that interaction produced.2. the noise that produced of the secondary eddy current in the runner.Wind forms the secondary eddy current in the air channel after the reflection of air channel shown in figure three, and the secondary eddy current is the major part of air channel noise.3. the noise that interact to produce between high velocity air and rectifier, the evaporimeter gear piece.4. the ducting outlet air-flow spreads the noise that produces the sparse formation of gas suddenly.5. air-flow separates on the blade interface and produces eddy current, and eddy current separates and produces the eddy current noise that comes off.The periodicity noise that present axial-flow fan produces in order to reduce in the air channel all adopts the mouse cage shape axial-flow fan that distributes at the axial screw shape, reaches the vibration phase machine cycle that changes blade with this, and then the phase place and cycle of air-flow in the entanglement air channel.Reduced periodic peak air flow noise though do like this, yet, but brought the wide band eddy current turbulence noise that comes off, this turbulence noise does not also have again effective method to eliminate at present, the general dissipative muffler that adopts comes noise reduction, dissipative muffler is a sound absorption of utilizing sound-absorbing material, the noise of propagating along the air channel constantly is absorbed and decay gradually, sound-absorbing material is fixed on the air channel perisporium that air communication is crossed, when sound wave enters dissipative muffler, just cause air and fiber vibration in the porous material in the dissipative muffler, because frictional resistance and viscosity resistance make a part of acoustic energy be converted into the effect that heat energy dissipation plays noise elimination.Yet this method but makes the cost of air-conditioner increase greatly, and windage is increased, and the ability of air-conditioner reduces.
The content of utility model
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of no air channel is provided, and can effectively reduce the air-conditioning noise, and and then improves the air conditioner room unit of heat exchange efficiency.
The utility model is achieved by following technical proposals.
The utility model comprises housing, be arranged on the evaporimeter and the fan system of enclosure interior, housing is provided with drainpipe, air inlet and air outlet, and wind direction board is installed in the place ahead of air outlet, fan system comprises fan and regulates the motor of rotation speed of the fan, the outlet of described evaporimeter is connected with compressor in being installed in off-premises station, air inlet wherein, air outlet is separately positioned on the backplate of housing, front plate, evaporimeter is plate shaped evaporimeter, its shape and window machine evaporimeter are similar to be two-layer laminated structure, can the identical square made from window machine evaporimeter, also can make garden sheet shape, fan is arranged between the front plate of evaporimeter and housing.During operation, air enters evaporimeter by the air inlet that is arranged on back side of shell and carries out heat exchange, and the air after the heat exchange is sent air-conditioner by the rotation of fan by air outlet.
Described fan is that axial width is the aerofoil fan of 40mm～60mm, and aerofoil fan is provided with the blade that 4～30, outer are circular arc, and this fan curvature changes little, and inleakage is little, can reduce noise.
