Abstract
The terminal equipment of central air conditioner using brushless DC motor has the features of no maintenance, high efficiency, low power consumption, good speed regulating performance, group control and automatic control.
Description
The present invention relates to the application of DC Brushless Motor in the central air-conditioning end-equipment.
The central air-conditioning end-equipment also is fan coil, typically refers to each chamber that is installed in the building pipeline cold air or hot gas, that central air-conditioning is produced everywhere and sends each chamber and equipment everywhere to.In the prior art, the motor that the central air-conditioning end-equipment is used all adopts the single phase alternating current (A.C.) asynchronous motor, and speed regulating method adopts motor windings tap mode, and the rotating speed stepping is many more, and tap is many more.When installing at the scene, easily the wrong line causes motor rotation undesired even burn motor and supply line.In addition, because rotation speed change is to have level to change (being generally three grades), so be difficult to satisfy the various needs of user.Simultaneously, AC asynchronous motor efficient is low, power consumption is big, temperature rise, electromagnetic vibration noise is big, volume is big, consumptive material is many, power consumption is high, and because speed governing difficulty and regulate and control inconvenience and be difficult to make central air-conditioning end-equipment realization team control, automatic control.
The purpose of this invention is to provide of the application of a kind of DC Brushless Motor, make this central air-conditioning end-equipment have freedom from repairs, efficient low-consume, good speed adjustment features, and can realize the characteristics of team control and automatic control at the central air-conditioning end-equipment.
The objective of the invention is to be achieved through the following technical solutions, the application of a kind of DC Brushless Motor at the central air-conditioning end-equipment is provided, wherein, this end-equipment adopts DC Brushless Motor.
Advantage of the present invention is, need not change the basic structure of central air-conditioning end-equipment, just can improve its performance index, after promptly in the central air-conditioning end-equipment, using DC Brushless Motor, the motor volume dwindles 40%, consumptive material reduces 30%, power consumption reduces by 45%, speed adjustable range is wide, speed governing is steady continuously, temperature rise is low (only is 35K, and alternating current machine reaches 70K), do not have to exchange the electromagnetic vibration noise of 50HZ/100HZ, particularly because speed governing is steady continuously, thereby can carry out team control and automatic control easily, also very convenient with computer or industrial control unit (ICU) interface.
Below in conjunction with accompanying drawing, describe embodiments of the invention in detail, so that more clearly understand the above-mentioned feature and advantage of the present invention.
Fig. 1 is a kind of front view of broken section of exposed type central air-conditioning end-equipment;
Fig. 2 is the left view of equipment shown in Figure 1;
Fig. 3 is a kind of front view of broken section of concealed central air-conditioning end-equipment;
Fig. 4 is the left view of equipment shown in Figure 3.
Referring to Fig. 1 and 2, they have shown a kind of exposed type central air-conditioning end-equipment one fan coil, this equipment is installed on the indoor wall or on the platform usually, it comprises the casing 2 that has air outlet 1, two be arranged symmetrically in the casing 2, each air inlet (not shown) is in communication with the outside and spiral case 3 that each air outlet (not shown) is communicated with casing 2, one be fixedly mounted in the casing 2, the DC Brushless Motor 4 between two spiral cases 3, and two be fixedly mounted on wind wheel 5 on the motor 4 two ends output shafts, that lay respectively at 3 li of spiral cases.
Referring to Fig. 3 and 4, they have shown a kind of concealed central air-conditioning end-equipment one fan coil, this equipment is installed in the indoor ceiling inboard usually, it comprises the casing 2 that has air outlet 1, two be arranged symmetrically in casing 2 outer upper end, each air inlet 6 is in communication with the outside and spiral case 3 that each air outlet (not shown) is communicated with casing 2, one is fixedly mounted on casing 2 outer upper end, the DC Brushless Motor 4 between two spiral cases 3, and two are fixedly mounted on wind wheel 5 on the motor 4 two ends output shafts, that lay respectively at 3 li of spiral cases.
Introduced two kinds of central air-conditioning end-equipments above, but in the central air-conditioning end-equipment of other type, also can use DC Brushless Motor, and these changes all should be included in the scope of protection of present invention.
