Abstract
The utility model relates to the technical field of air conditioners, in particular to a fan-coil unit. The fan-coil unit structurally comprises an air return device, wherein the air return device comprises an air return port and a plurality of air guide pieces arranged on the air return port; by arranging the air return device on one side, far away from an air outlet of the fan-coil unit, of the lower end face of the fan-coil unit, airflow is prevented from entering the air suction area of the air return port after being blown out from the air outlet, and a circulation path of the airflow is prolonged, heat exchange of indoor air is sufficient, and therefore the energy utilization rate of the fan-coil unit is improved, the dip angle of the air guide pieces relative to the horizontal plane is 75-85 degrees, the air suction efficiency of the air return port is improved, and the energy utilization rate of the fan-coil unit is further improved.
Description
Technical field
The utility model relates to air-conditioning technical field, particularly relates to a kind of fan coil units.
Background technology
Fan coil units is the end equipment of air-conditioning system, and its operation principle is in unit, constantly to recycle room air, makes air pass through to be cooled (heating) after cold water (hot water) coil pipe, to keep the constant of room temperature.Conventionally, indoor by sending into after new blower fan group processing, to meet the needs of air-conditioned room resh air requirement.So fan coil units operated by rotary motion has the exhaust apparatus of sending suitable temperature air-flow, and the air-returning device that sucks room air, air-returning device generally comprises return air inlet; In order to guarantee the air draught efficiency of return air inlet, described return air inlet operated by rotary motion has return air grid.
General and the air outlet of the air-returning device of existing fan coil units is from close to must be, cause new wind that air outlet blows out fully and room air carry out heat exchange, enter the air draught scope of the return air inlet of air-returning device, and again sucked in fan coil units, this has reduced the capacity usage ratio of fan coil units.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and a kind of fan coil units that improves capacity usage ratio is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fan coil units is provided, comprise air-returning device, air-returning device comprises return air inlet and is arranged at a plurality of guide vanes of return air inlet, in the utility model, air-returning device is arranged on fan coil units lower surface away from a side of the air outlet of fan coil units, and the inclination angle of guide vane relative level face is 75 °～85 °.
Wherein, the inclination angle of guide vane relative level face is 80 °.
Wherein, top, the top of guide vane is provided with horizontal stand.
Wherein, horizontal stand is placed with screen pack.
Wherein, the opening of horizontal stand is positioned at the side of fan coil units.
Wherein, horizontal stand upper end is provided with the shielding cover of turnover screen pack.
The beneficial effects of the utility model: the utility model is by being arranged on air-returning device fan coil units lower surface away from a side of the air outlet of fan coil units, avoided air-flow from air outlet blows out, to enter the return air inlet air draught region of fan coil units, be conducive to extend the circulating path of air-flow, make room air heat exchange abundant, thereby improved the capacity usage ratio of fan coil units, the inclination angle of guide vane relative level face is 75 °～85 °, can improve the air draught efficiency of return air inlet, further improve the capacity usage ratio of fan coil units.
Accompanying drawing explanation
Utilize accompanying drawing to be described further utility model, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram at A place in Fig. 1.
In Fig. 1 and Fig. 2, include:
11---return air inlet, 12---guide vane, 13---screen pack, 14---shielding covers;
2---air outlet.
The specific embodiment
With the following Examples the utility model is further described.
A kind of fan coil units of the present embodiment, as depicted in figs. 1 and 2, comprise air-returning device, air-returning device comprises return air inlet 11 and is arranged at a plurality of guide vanes 12 of return air inlet 11, guide vane 12 recedes to lower end from top, in the present embodiment, air-returning device is arranged on fan coil units lower surface away from a side of the air outlet 2 of fan coil units, and the inclination angle of guide vane 12 relative level faces is 75 °～85 °.Particularly, the inclination angle of guide vane 12 relative level faces is 80 °.It is best angle that inclination angle is 80 °, and the air draught of return air inlet 11 is most effective.
Wherein, top, the top of guide vane 12 is provided with horizontal stand, and horizontal stand is placed with screen pack 13.Screen pack 13 is for filtering and purify sucking the wind of return air inlet 11.
Wherein, the opening of horizontal stand is positioned at the side of fan coil units.Conveniently screen pack 13 is put into horizontal stand or extract out from horizontal stand.
Wherein, horizontal stand upper end is provided with the shielding cover 14 of turnover screen pack 13.When needs are extracted screen pack 13 out, the shielding cover 14 that first upwards overturns, then extract screen pack 13 out; After putting into screen pack 13, shielding cover 14 is covered, can prevent that extraneous foreign matter from falling into screen pack 13.
The utility model is by being arranged on air-returning device fan coil units lower surface away from a side of the air outlet 2 of fan coil units, avoided air-flow from air outlet 2 blows out, to enter the return air inlet 11 air draught regions of fan coil units, be conducive to extend the circulating path of air-flow, make room air heat exchange abundant, thereby improved the capacity usage ratio of fan coil units, the inclination angle of guide vane 12 relative level faces is 75 °～85 °, can improve the air draught efficiency of return air inlet 11, further improve the capacity usage ratio of fan coil units.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
