Specific embodiment

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in more detail.

The indoor set of the present embodiment mainly includes housing 1, has air inlet 8 and air outlet 9, air inlet 8 He on housing 1 Air outlet 9 is arranged at housing 1 bottom, has the air channel of connection air inlet 8 and air outlet 9 in housing 1, arranges in air channel There are heat exchanger 3 and cross flow fan 2, be provided with filter screen 5 and grid 6 at air inlet 8, be provided with air outlet 9 and sweep air blade 7, shown in Figure 2, it is provided with drip tray 4 below housing 1 bottom, heat exchanger 3, the position of drip tray 4 is wrong with air inlet 8 Open, the floor projection of heat exchanger 3 is entirely located in drip tray 4；On housing 1 top, the position relative with air inlet 8 is laid with arc Shape plate 1-1, the extrados of arc 1-1 is towards hull outside.

The indoor set of the present embodiment, because drip tray 4 is staggered with air inlet 8 position, air is through air inlet 8, grid 6, filter In net 8 suction casing 1, it is to avoid drip tray 4 produces resistance, the air-breathing of indoor set to the air entering through air inlet 8 in housing 1 Uniformity substantially improves, and avoids air-flow to interact with drip tray 4 simultaneously and produces noise；Because drip tray 4 is located under heat exchanger 3 Side, it is to avoid the air-flow of heat exchanger 3 windward side is subject to stopping of drip tray 4, forms uniformity in heat exchanger 4 windward side and preferably flows Field distribution, improves airflow homogeneity, improves the exchange capability of heat of heat exchanger 3, reduces the gas causing due to uneven flow field Dynamic noise；The floor projection of heat exchanger 3 is entirely located in drip tray 4, it is to avoid the condensing drip of heat exchanger 3 is fallen outside drip tray 4； Blow to arc 1-1 through the air that air inlet 8 enters within housing 1, arc decreases the formation in flowing whirlpool, reduces air channel Middle level is folded to the drag losses of heat exchanger air-flow, is conducive to improving air-supply uniformity, therefore after the guiding through arc 1-1, Air-flow is folded to heat exchanger 3, forms uniform air flow, further increase the gas on heat exchanger 3 windward side on heat exchanger 3 windward side Stream uniformity, the arrow in Fig. 2 is the direction of air-flow.

In the present embodiment, heat exchanger 3 includes multiple rows of tube bank, the parallel laying of multiple rows of tube bank, in adjacent row tube bank in the heart Equal away from p；Every comb bundle all includes multiple heat exchanger tube 3-1 laying at equal intervals, and described heat exchanger tube is pipe, in every comb bundle In, the line of centres of all heat exchanger tubes is in alignment；Center distance ft of two neighboring heat exchanger tube in every comb bundle and phase The center distance of the two neighboring heat exchanger tube in adjacent comb bundle is equal；Heat exchanger tube is connected with the center of its projection on perpendicular Line passes through the midpoint of the line of centres of neighbouring two heat exchanger tube in adjacent row tube bank；Heat exchanger tube is with it in adjacent row tube bank The line of centres of projection and this heat exchanger tube and this adjacent row tube bank the line of centres of neighbouring heat exchanger tube between angle β be:

$\mathrm{\β}=arctan\frac{\frac{ft}{2}-\frac{p}{tan\mathrm{\θ}}}{p},$

Wherein, the center distance that p restrains for adjacent row, ft be in two neighboring heat exchanger tube in every comb bundle in the heart Away from θ is the angle (the namely angle of inclination of heat exchanger) of every comb bundle and horizontal plane.

Shown in Figure 3, the center of the heat exchanger tube 3-1 in heel row tube bank is designated as a, neighbouring in adjacent front-seat tube bank The center of two heat exchanger tubes is denoted as b and c, and the midpoint of b and c line is d, b and d wire length is ft/2；A is in front-seat tube bank On be projected as e, that is, the line of a and e is perpendicular to the line of b and c；A and its projection join line on perpendicular pass through d, b and The wire length of e is designated as l1, and the arrow in Fig. 3 is airflow direction, and flow level flows to heat exchanger.

L1=p tan β,DrawThen draw

That is, laying adjacent two according to tube bank and the angle theta of horizontal plane (i.e. the angle of heat exchanger and horizontal plane) The heat exchanger tube of comb bundle, to reduce the barrier effect to heel row tube bank for the front-seat tube bank, reduces front-seat tube bank and restrains air to heel row The impact of flow velocity, so that the air volume adjustment of the front-seat tube bank of heat exchanger and heel row tube bank is more uniform, improves heat exchanger further Heat exchange efficiency, reduces the energy consumption of heat exchanger, improves the heat exchange property of heat exchanger, improves whole whole function effect, and then improves room The market competitiveness of interior machine.

In the present embodiment, the heat exchanger tube in multiple rows of tube bank pipe external diameter is equal, tube thickness is equal, i.e. institute in heat exchanger There is the specification of heat exchanger tube identical, the processing technique to simplify heat exchanger.

Certainly, the heat exchange tube diameter in adjacent row tube bank can also be different.For example, the caliber of heel row heat exchanger tube is more than front row The caliber of heat exchanger tube, be further ensured that the heat exchange property of heel row heat exchanger tube it is ensured that heat exchanger air-supply uniformity.Same comb The caliber of the heat exchanger tube in bundle can also be different.

The pipe external diameter of each heat exchanger tube is 4mm～9mm, has not only met heat exchange demand but also has avoided that pipe external diameter is excessive to cause material Waste.

Based on the design of above-mentioned indoor set, the present embodiment also proposed a kind of air-conditioning, including off-premises station and described interior Machine, off-premises station and indoor set connect.

By designing described indoor set in air-conditioning, the heat exchange property improving air-conditioning is so that air-conditioning has stronger city Field competitiveness.

Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, Change, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model, Also protection domain of the present utility model should be belonged to.
