The specific embodiment
Existing concrete with reference to the exemplary embodiment to the application, the application's embodiment is shown in the drawings.As long as maybe, in institute's drawings attached, identical reference number will be used to indicate same or analogous part.
Fig. 1 is the diagram that illustrates according to the application's building terminal fan coil unit exemplary embodiment.As shown in Figure 1, building terminal fan coil unit 100 can independently be installed in the room.In one embodiment, building terminal fan coil unit 100 can depend on fabric structure 140 and install, and recessed furred ceiling 141.Shell 120 inboards of fan coil unit 100 are blower fan 110 and heat exchanger 112 at the building terminal.Can at least one fan air inlet 130 and at least one blower fan exhaust outlet 135 in the diapire 121 of shell 120.Blower fan 110 can (for example pass through air inlet 130) from corresponding room suction air, and through heat exchanger 112, pass exhaust outlet 135 with the air with conditioned and discharge go back to the room.In one embodiment, building terminal fan coil unit 100 can be the room air conditioner unit.
As shown in Figure 2, can on the lower surface of the shell 120 of building terminal fan coil unit 100, extra blower fan exhaust outlet 132,133 be set.Alternatively, can use fan air inlet more than one.
In operation; Blower fan 110 passes air inlet 130 suction airs (for example, returning air), makes air pass filter 150; Air is passed regulate the heat exchanger 112 of air, and via exhaust outlet 135 (for example 132,133) air is discharged go back to the room subsequently.Replacedly, the parts of building terminal fan coil unit 100 can use other layouts, and for example, heat exchanger 112 can be positioned in air-flow after the blower fan 110, and perhaps parts can be boxlike FCU layout around blower fan 110.
Fig. 3 is the sketch map according to the embodiment of the application's building terminal fan coil unit, wherein, shows the air inlet/return air chamber of the single band pipeline on furred ceiling and the single air exhaust port that gets into the room.As shown in Figure 3, fan air inlet 134 can be formed at respectively in the sidewall (for example, single sidewall) of shell 120, and is communicated with the common dead air space phase fluid between fabric structure 140 and furred ceiling 141 is mobile.In one embodiment, return air (for example, conduit, air vent) parts and be not integrally formed as the part of building fan coil unit 100.Therefore, providing the fluid that passes furred ceiling 141 from the room to flow the conduit (not shown)/return air chamber that connects can be spaced apart with building fan coil unit 100.Interchangeable, isolated return air parts can be connected to the fan air inlet (for example, 134) of building terminal fan coil unit 100.Therefore, pass furred ceiling 141 provide the fluid that arrives the room to flow the conduit (not shown)/air supplying chamber that connects can be spaced apart with building fan coil unit 100.Interchangeable, isolated air feed parts can be connected to the blower fan exhaust outlet (for example, blower fan exhaust outlet 135) in the sidewall of building terminal fan coil unit 100, to save the air-flow exhaust outlet that directly passes shell 120 to room.
In one embodiment, building terminal fan coil unit can be installed on the ceiling or on the ceiling, or on the wall in room or in the wall, or on the room base plate or in the room base plate.And, can also be installed in the room with furred ceiling according to the embodiment of the application's building terminal fan coil unit.
