Abstract
The utility model discloses a variable air volume terminal device with a rectifier gate of an air conditioning system. The device comprises an inlet straight tube segment, a rectifier gate, a variable air volume terminal device and a blowing muffler which are connected in sequence. The length of the inlet straight tube segment is twice as many as the diameter of an inlet straight tube. The rectifier gate is additionally arranged between the inlet straight tube segment and the variable air volume terminal device and the variable air volume terminal device is provided with the muffler, therefore, the length of the inlet straight tube segment is reduced, the space occupied by installation is reduced, the noise of the device is reduced, the accuracy of the measurement of air volume is guaranteed, good controlling ability and adjusting quality of a valve in the variable air volume terminal device are guaranteed, and optimized usage of the variable air volume air conditioning system is achieved.
Description
Technical field
The utility model relates to a kind of air-conditioning system variable air rate end equipment with honeycomb screen, is the further improvement to air conditioning system with variable.
Background technology
Variable air rate (Variable Air Volume, VAV) air-conditioning system is a kind of form of all-air conditioning system, and it is a new technology that grows up along with the energy-conservation requirement of air-conditioning.And whether can move safely, reliably, economically for air conditioning system with variable, not only depend on system, lectotype selection, and depend on that structure is whether rationally correct, wherein can air quantity variable end device accurately regulate the energy saving that air quantity can directly have influence on temperature controlled accuracy and system in the room.
At present, most of documents, product sample and engineering experience all point out, should be greater than the inlet tube diameter of 4～5 times with the length of the import straight length of the air quantity variable end device of honeycomb screen.And common practice is that the length of choosing vav terminal import straight length is at least 5 times of inlet tube diameters on engineering.Take over the not only pipeline section waste of long straight length in import, take larger space, increase the noise of device, and have influence on air-conditioning system and can not accurately regulate air quantity.
The utility model content
The utility model discloses a kind of air-conditioning system variable air rate end equipment with honeycomb screen, can effectively overcome in the air quantity variable end device of not being with honeycomb screen the problems such as existing air quantity is unstable, cause the pipeline section waste because the import straight length is long, take larger space, increase the noise of device, and have influence on the drawback that air-conditioning system can not accurately be regulated air quantity.The utility model is to install honeycomb screen additional between import straight length and air quantity variable end device, and install silencer additional at air quantity variable end device, not only reduced the length of import straight length, and reduce to take up room, reduce the noise of device, effectively improve the accuracy of air measuring, guaranteed good control ability and the quality of regulation of valve in air quantity variable end device, realized that the optimization of air conditioning system with variable is used.
Technical solutions of the utility model are achieved in that
A kind of air-conditioning system variable air rate end equipment with honeycomb screen, by the import straight length, honeycomb screen, air quantity variable end device body, the air-supply silencer forms, and it is characterized in that: import straight length, honeycomb screen, air quantity variable end device body, air-supply silencer are linked in sequence successively.
Described import flow development length is the twice of import straight tube diameter.
The utility model is simple in structure, add honeycomb screen between import straight length and air quantity variable end device body, and install silencer additional at air quantity variable end device, reduced the waste of taking over long straight length in import, reduced the space that takies is installed, reduced the noise of device, guaranteed the accuracy of air measuring, guaranteed good control ability and the quality of regulation of valve in the air quantity variable end device body, realized that the optimization of air conditioning system with variable is used.
Description of drawings
Fig. 1 is the air quantity variable end device structural representation of the utility model air-conditioning system.
1, import straight length, 2, honeycomb screen, 3, the air quantity variable end device body, 4, the air-supply silencer.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
A kind of air-conditioning system variable air rate end equipment with honeycomb screen, structure is as shown in Figure 1: by import straight length 1, honeycomb screen 2, air quantity variable end device body 3 and air-supply silencer 4 form, import straight length 1, honeycomb screen 2, air quantity variable end device body 3, air-supply silencer 4 are linked in sequence successively, and described import flow development length is the twice of import straight tube diameter.
The utility model air-supply silencer 4 is comprised of casing and liner; Liner is cotton for eliminating the noise, and wraps up with smooth gauze.
Honeycomb screen is to select according to the shape in air channel, is applicable to rectangular duct and square air channel, the present embodiment square air channel, therefore honeycomb screen 2 is selected square honeycomb screens, long 100mm divides five lattice, each grid length of side 20mm, the aluminium sheet of material selection δ=0.3mm.
Can also air quantity variable end device be moved in the furred ceiling in less important room according to use occasion in Practical Project, or use defening effect ceiling material preferably instead, with the impact of further noise decrease on the groundwork district.
Compare with the air-conditioning system variable air rate end equipment with honeycomb screen not with the air-conditioning system variable air rate end equipment of honeycomb screen, the stability of its air-flow is stronger, and the noise near medium-high frequency (1000Hz) has good soundproof effect, the maximum noise that can reduce 10dB, silencing noise effect to low frequency is relatively better, can reduce by 4～6dB.
Claims (2)
1. air-conditioning system variable air rate end equipment with honeycomb screen, by the import straight length, honeycomb screen, air quantity variable end device body, the air-supply silencer forms, and it is characterized in that: import straight length, honeycomb screen, air quantity variable end device body, air-supply silencer are linked in sequence successively.
2. a kind of air-conditioning system variable air rate end equipment with honeycomb screen according to claim 1, it is characterized in that: described import flow development length is the twice of import straight tube diameter.
