Abstract

The utility model relates to an end device connected to the back of an indoor machine through an air channel. Thereby, the effect of one-drag-multiple user central air conditioner can be achieved by adopting a blower at one end for inducing air. The utility model comprises an outdoor machine, an indoor machine and an air pipe of a straightly expanding type air conditioning system. The utility model is characterized in that the end of the air pipe of each indoor machine is provided with one to three variable air volume end air inducing devices.

Description

Variable air rate one drags the multiple user central air-conditioning

The utility model belongs to field of air conditioning, specifically utilize the multi-split air conditioner technology, connect a plurality of air channels at air outlet of indoor set, induce blower unit that air quantity is reallocated, and can reach a kind of novel residential central air-that each end can independently be controlled by end.

Residential central air-has following three major types type at present:

(1) many typhoons of small-sized cold water machine assembly coiler, this type cost is higher;

(2) off-premises stations drag many indoor sets, and this type cost is also high, and the fluorine pipe is long partially;

(3) off-premises stations connect an indoor set; Indoor set is assigned to each by airduct and air-valve again

Individual room. such shortcoming is that control fully separately can not be accomplished in each room, and

Energy consumption is very big.

(4) factories such as (MIDEA) of Da Jin (DAIKIN), Haier (HAIER), U.S.

One of family drags many residential central air conditionings to adopt converter technique, and is with high costs, and maintenance is stranded

Difficult.

The purpose of this utility model is to avoid the weak point in above-mentioned prior art and the integrated cost, connect end equipment in the indoor set back by the air channel, thereby provide a kind of employing blower fan to induce air inducing endways, to reach the effect of dragging the multiple user central air-conditioning.

The purpose of this utility model can reach by following measure:

Variable air rate one drags the multiple user central air-conditioning, comprises off-premises station, the indoor set of straight-expansion type air conditioner system, and airduct is characterized in that the airduct end of each indoor set has 1 to 3 vav terminal blower unit.

The purpose of this utility model also can reach by following measure:

Indoor set can adopt 1 to 3;

Indoor set adopts 2, and the airduct end of every indoor set has 2 vav terminal blower units.

The relative prior art of the utility model has following advantage:

The utility model vav terminal blower unit and one drag two air-conditioner are used in combination, and whole system is reached drag the quadruple effect fruit, in theory also can reach one of more ends and drag the multiple-effect fruit.

The utility model tail end box body and function foaming plate had both reached heat insulation effect, can reduce noise significantly again, adopted the cross flow fan factory of low noise, made the room conditioning noise fall very lowly.Adopt ultra-thin single air intake three air-out centrifugal blowers that good air-out effect is arranged, installation and maintenance are convenient, good looking appearance.

The utility model reduces indoor set air-out static pressure greatly in indoor set back plenum chamber structure, weakens influencing each other when moving between the air channel, has guaranteed the possibility of each terminal independent control.

The utility model can be able to make native system reach the architectural appearance and the indoor installation effect of central air-conditioning design, compares with general residential central air conditioning, and conserve energy, cost is low, and control is convenient, and operating cost is cheap, can satisfy numerous users' demand.

Fig. 2 is two of the utility model structural representation.

Fig. 3 is three of the utility model structural representation.

Fig. 4 is one of the utility model air quantity variable end device profile.

Fig. 5 is two of the utility model air quantity variable end device profile.

Below in conjunction with accompanying drawing the utility model is further described:

Twoly advance singly to go out centrifugal blower 2 and be installed in the indoor set front, dual-axle motor 1 adopts single-speed motor, makes the indoor set blower fan be in the constant speed operation all the time.Wind is drawn into through airduct, after the indoor machine evaporation heat exchange, sends into plenum chamber 4, and the plenum chamber inner surface pastes insulation material 5.

In the terminal blower unit of the utility model through-flow centrifugal blower, cross flow fan or axial flow blower and adjustable speed motor are housed, generally select low noise for use, the cross flow fan 8 of aesthetic property is arranged, as shown in Figure 4 again.With foam box body structure 6, be installed in the indoor wall in terminal, adopt local furred ceiling in the next door room.The air-out barrier 9 that inner wall surface is equipped with the wind-guiding effect is hidden in body in the body of wall.

The utility model indoor set also can adopt ultrathin type singly to advance singly to go out centrifugal blower 3 air-supplies, can reduce cost greatly, reduces the indoor set height, as shown in Figure 2.

The utility model adopts the vav terminal blower unit, when longer relatively, can adopt the blower fan air-supply in the air channel in the indoor set, and as previously described, when design and installation, the air channel is extremely short or do not have an air channel, the utility model centrifugal blower of can blowing as shown in Figure 3.

The utility model vav terminal blower unit can hang over whole end on the wall with wall-hanging single air intake three air-out centrifugal blowers, as shown in Figure 5, can reach good air-out effect and aesthetic property.
