Technical field
The utility model relates to a kind of outdoor machine of body-separated air-conditioner.
Background technology
Outdoor machine of body-separated air-conditioner generally includes housing, compressor, condenser assembly and fan assembly etc.In process of refrigerastion, the refrigerant gas of HTHP is discharged by compressor, enter condenser assembly, carry out heat exchange with the air that under the effect of fan assembly, flows through condenser assembly, make the refrigerant gas liquefaction of HTHP be the refrigerant liquid of HTHP, finish the condensation process in condenser assembly.As shown in Figure 1, in the off-premises station of prior art, the L shaped right angle bending heat exchanger of condenser assembly 2 general employings is the surface plate block-like design.Compressor 1 and fan assembly 3 are enclosed in the condenser assembly 2, and an arc 4 is arranged between compressor 1 and the fan assembly 3.Show that according to the wind speed profile that measures from the condenser assembly outside adopt L shaped condenser assembly, the wind speed that measures in the condenser assembly stage casing is bigger, the end wind speed is less, particularly near arc and condenser assembly joint section.Because the inhomogeneities of its wind speed profile, and the irrationality of condenser assembly design make the heat exchange efficiency of condenser assembly be difficult to be further improved, and also are provided with obstacle for the miniaturization of air-conditioner outdoor unit.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, by the rational Design on Plane to condenser assembly, proposes the outdoor machine of body-separated air-conditioner that a kind of heat exchange efficiency improves.
The purpose of this utility model is achieved through the following technical solutions: a kind of outdoor machine of body-separated air-conditioner, comprise compressor, condenser assembly, fan assembly, the housing in the described condenser assembly outside is provided with air inlet, the housing of described fan assembly side is provided with air outlet, the fan blade of described fan assembly is a shaft flow blade, described fan assembly is enclosed in described condenser assembly inboard, described condenser assembly is divided into three sections, its interlude and compressor side section and opposite side section all constitute certain included angle, and described compressor is placed on outside the described condenser assembly.
Experiment shows, adopt condenser assembly described in the utility model, can solve near section problem that wind speed is less than normal of condenser assembly and arc joint, thereby improved the heat exchange efficiency of condenser assembly, the refrigerating capacity of the off-premises station of identical appearance size is improved, that is to say,, utilize the appearance and size of the off-premises station of this structure to be reduced accordingly if reach identical refrigerating capacity.

Fig. 2 is the structural representation of an embodiment of the utility model outdoor machine of body-separated air-conditioner;
Fig. 3 is the wind speed profile schematic diagram in the condenser assembly outside of existing off-premises station;

The specific embodiment
As shown in Figure 2, a kind of outdoor machine of body-separated air-conditioner, comprise compressor 1, condenser assembly 2, fan assembly 3, the housing in described condenser assembly 2 outsides is provided with air inlet, the housing of described fan assembly 3 sides is provided with air outlet, and described fan assembly 3 fan blades are shaft flow blade; Described condenser assembly 2 is divided into three sections: compressor side section L3, interlude L2 and opposite side section L1, and interlude L2 and compressor side section L3 formation angle α constitute angle β with opposite side section L1; Described fan assembly 3 is enclosed in described condenser assembly 2 inboards, and described compressor 1 is placed on outside the described condenser assembly 2.
Because described condenser assembly is designed to as the shape among Fig. 2, for having more substantial air, the L3 section that makes described condenser assembly flows through, further improve the heat exchange efficiency of described condenser assembly, on the housing of the right side of described compressor 1 and rear side, can also have air inlet.
Fig. 3 is the wind speed V distribution schematic diagram in the prior art outdoor condenser assembly outside, and in measurement, the rotating speed of axial flow blower is 900rpm.For the off-premises station that adopts L shaped right angle bendable condenser assembly, the V value of condenser stage casing L2 is bigger, be 2.32m/s to the maximum, the V value of two ends L1, L3 is respectively 1.03m/s, 0.66m/s, that is to say, an end L3 heat exchange efficiency that joins at described condenser assembly and arc greatly descends, and will inevitably cause the heat exchange of condenser assembly low like this.
Shown in Fig. 4 (a), in measurement, the rotating speed of axial flow blower is 900rpm.During for employing condenser assembly of the present utility model, because the angle β of a condenser stage casing L2 and an end L1 section is 90 °, the V value of a condenser stage casing L2 and an end L1 section is compared constant substantially with correspondent section in the prior art, but its V value has been enhanced several times for the L3 section, mean value is 1.72m/s, this moment condenser assembly L2 section and L3 section angle α=120 °.In the drawings, A is that the left end point B of L3 section is the intersection point of L2 section and blower fan axis.
Wind speed V distribution schematic diagram when Fig. 4 (b) and 4 (c) are respectively angle α=105 °, α=150 ° of condenser assembly L2 section of the present utility model and L3 section.Experiment shows, under the condition of the invariant position of the intersection points B of the left end point A that keeps the L3 section and L2 section and blower fan axis, along with the increase of α angle, wind speed V is even more in the distribution of L3 section, and the wind speed of segmental arc is also big more, correspondingly can reduce relatively at L2 section wind speed.Simultaneously, angle α can be subjected to the restriction of the structure of off-premises station.
Shown in Fig. 4 (d), under described angle α=120 ° and the condition that remains unchanged, by the measured wind speed profile schematic diagram of the bending radius of curvature that increases described condenser assembly L2 section and L3 section.In conjunction with Fig. 4 (a) and Fig. 4 (d), we can learn, keeping under the constant condition of described angle α, bending radius of curvature increase along with described condenser assembly L2 section and L3 section, wind speed on the bending segmental arc is also along with increase, mean wind speed on the described condenser assembly L3 section increases, and the mean wind speed of L2 section descends to some extent.
When angle α=90 of described condenser assembly L2 section and L3 section °, the shape of condenser develops into the axis symmetry with described fan assembly, and at this moment, the wind speed profile of described condenser assembly L1 section and L3 section is also roughly the same.
α is the same with angle, and the value of angle β also can change in certain scope, and span also can be for more than or equal to 90 °.Equally, when value one timing of angle β, along with the bending radius of curvature increase of described condenser assembly L2 section and L1 section, the wind speed on the bending segmental arc is also along with increase, mean wind speed on the described condenser assembly L3 section increases, and the mean wind speed of L2 section can descend to some extent.Cause that about the variation of angle β the situation that wind speed profile changes can not give unnecessary details at this referring to the various situation of change schematic diagrames of angle α.
Experiment shows, adopts split-type air conditioner off-premises station described in the utility model, owing to improved the heat exchange efficiency of condenser assembly, the refrigerating capacity of the off-premises station of identical appearance size is improved, data show according to statistics, and refrigerating capacity improves 8%, and Energy Efficiency Ratio improves 10%; That is to say,, utilize the appearance and size of the off-premises station of this structure to be reduced accordingly if reach identical refrigerating capacity.Simultaneously, because the distribution of wind speed on condenser assembly is more even, make the noise of off-premises station also descend to some extent.
