Abstract

The utility model particularly relates to a double crossflow split floor type room air conditioner which comprises a machine body, wherein the machine body is provided with an air inlet and an air outlet; two crossflow impellers with reverse rotating directions are installed in the machine body, and the crossflow impellers are respectively positioned in two eddy casings which are mutually conjoined as a whole; two eddy tongues are correspondingly installed on both sides of an inner air outlet of the machine body, and heat exchangers are respectively installed on both sides of the intracavity of the machine body. The utility model adopts two symmetrical crossflow impellers, and the double crossflow effect is generated under the cooperation of the eddy casings and the eddy tongues, and thus, the air quantity is raised, the air inlet area is enlarged, the air outlet area is widened and the wind speed and the noise are reduced. In addition, the utility model adopts two sets of identical heat exchangers or heat radiators, which increases the evaporation area.

Description

Two through-flow separated floor room air conditioners

Technical field:

The utility model relates to the air-conditioner technical field, refers in particular to a kind of pair of through-flow separated floor room air conditioner.

Background technology:

Efficiency grade according to China's regulation, do the high energy efficiency type and must increase by two device area and air quantity, certainly will make the loom of relatively little cold use the kernel of bigger volume, taking up room also makes noise improve, and this point causes obstruction when most of user in city is selected.At present, the operation principle of common cabinet-type air conditioner is: wind by centrifugal blower pressurization after-blow to evaporimeter or wind go by the centrifugal blower sucking-off again through evaporimeter earlier.But under certain kernel, to accomplish high energy efficiency, can only be with regard to present existing cabinet-type air conditioner:

One, increases the row's number or the minimizing fin pitch of fins of evaporimeter.Though increase row's number of evaporimeter or reduce a fin pitch of fins and can increase evaporator area, but, if increase evaporimeter row number, when pressure head diameter Reynolds number during greater than certain value, pipe row is several, and influences to heat exchange performance reduce, in the real system coupling, we are increased to three rows to two row's evaporimeters, evaporation effect does not obviously promote, and has improved the difficulty of system's shunting and the unstability of system on the contrary, and has increased windage.Like this, you must improve rotating speed and keep air quantity (increase power of motor).In addition, because " priming effect " of calking formula fin, wind speed is during less than certain value, and along with the increase of row's number, heat exchange performance sharply descends; If reduce a fin pitch of fins, to common finned-tubes exchanger, heat exchange property can improve along with reducing of a pitch of fins, but the heat exchange performance of fenestration fin and pitch of fins relation are little, for the above heat exchanger of three rows, heat exchange property can reducing and variation along with a fin pitch of fins.Reduce a pitch of fins and increase windage equally, occur above problem equally.

Two, improve wind speed and strengthen heat exchange (air intake/outtake surface is long-pending not to be changed).It is very effective that this mode improves efficiency in certain limit, but increasing noise also is " getting instant result ".Simultaneously, when the wind speed that passes heat exchanger reaches one regularly, it is very little to improving heat exchange to increase wind speed (also being to improve air quantity) again.

Therefore, to accomplish that on the architecture basics of the console mode room air conditioner of prior art high energy efficiency can only be large volume, high power consumption and produce high noisy.

Summary of the invention:

The purpose of this utility model is at the deficiencies in the prior art part, provides that a kind of compact conformation, volume are little, low noise, low-power consumption, two through-flow separated floor room air conditioner adjusters cheaply.

For achieving the above object, the technical scheme that the utility model provides is: include body, body is provided with air inlet and air outlet, and the through-flow impeller of two switched in opposite is installed in body, the through-flow impeller lays respectively in two volutes, and it is an integral body that two volutes mutually combine; The both sides correspondence of air outlet is equipped with two whirlpool tongues in body, and the both sides of body inner chamber are separately installed with heat exchanger.

Operation principle of the present utility model is: during work, by the through-flow impeller rotation of the driven by motor correspondence of two switched in opposite, owing to there is the effect of snail tongue and spiral case, make that the through-flow impeller is inner to form eccentric vortex near snail tongue place, flow thereby form directed air.Air-flow enters from air inlet, and flow through heat exchanger or radiator are realized the energy transmission, and then runs through impeller and strengthen mutually at the outlet flow place, flows out from air outlet at last.Whole process realizes the regulating action to air.

The utility model adopts the through-flow impeller of two symmetries, under the cooperation of volute and whirlpool tongue, produces the effect of two through-flows, has improved air quantity, has strengthened incoming air area and widened air-out area, has reduced wind speed, has reduced noise.The utility model adopts same heat exchanger or the radiator of two covers in addition, has increased disengagement area.

Description of drawings:

Accompanying drawing 1 is the stereochemical structure decomposing schematic representation of the utility model preferred embodiment;

Accompanying drawing 2 is the utility model structural representation.

The specific embodiment:

Below in conjunction with a preferred embodiment and accompanying drawing thereof the utility model is described further,

See shown in accompanying drawing 1～accompanying drawing 2, preferred embodiment includes body 1, the both sides of body are provided with air inlet 2, antetheca is provided with air outlet 3, the through-flow impeller 4 of two switched in opposite is installed in body 1, and drive by blower fan respectively, through-flow impeller 4 lays respectively in two volutes 5, and it is an integral body that two volutes 5 mutually combine; The both sides of corresponding air outlet 3 are equipped with two whirlpool tongues 6 in body 1, and the both sides of body inner chamber are separately installed with heat exchanger 7, and the both sides of heat exchanger 7 correspondence respectively are fixed on volute 5, the whirlpool tongue 6.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
