Description
Technical field
The utility model relates to a kind of Heating,Ventilating and Air Conditioning more particularly to a kind of heating systems for large space.
Background technique
The air conditioning and heating of large space, such as airport, high-speed rail marquis's vehicle hall, gymnasium place generally use swirl diffuser
Air-supply depth is improved, human height area is reached.However, in some existing transformation projects being reluctant that existing dress is transformed in face of user
It repairs, when not having using swirl diffuser condition, the air conditioning and heating effect of large space is generally poor.
Utility model content
The utility model discloses a kind of heating systems for large space, empty to solve large space in the prior art
Adjust the problem of heating effect difference.
The above-mentioned purpose of the utility model is achieved through the following technical solutions:
A kind of heating system for large space, wherein include: to be equipped between a total air supply tube and a total backwind tube
One air-conditioning box is communicated with more on total air supply tube and separates air hose, and described separate is equipped with electric control valve in air hose, described
One pressure sensor is installed, an air-conditioner control system connects the electric control valve, the pressure sensor in total air supply tube.
The heating system as described above for being used for large space, wherein described separate is equipped with deflector in air hose.
The heating system as described above for being used for large space, wherein the wind tube outlet that separates is equipped with web plate.
The heating system as described above for being used for large space, wherein the air-conditioning box is connected with air-conditioning water inlet pipe, air-conditioning
Return pipe is equipped with control valve on the air-conditioning return pipe.
The heating system as described above for being used for large space, wherein the air-conditioner control system is PLC control system.
In conclusion by adopting the above-described technical solution, the utility model passes through air-conditioning by increasing electric control valve
Control system connects electric control valve and pressure sensor, and air-conditioner control system can control electric control valve work, adjust out
Vent area, so as to adjust wind speed wind speed out, it is empty that air-conditioner controller can also adjust air-conditioning box according to the data of pressure sensor
2 wind speed of case is adjusted, to effectively improve the heating effect of large space.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the utility model for the heating system of large space.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples:
Fig. 1 is structural schematic diagram of the utility model for the heating system of large space, and referring to Figure 1, one kind is used for
The heating system of large space, wherein include: to be equipped with an air-conditioning box 2 between a total air supply tube 1 and a total backwind tube 3, always send
It is communicated with more on air hose 1 and separates air hose 4, separates and electric control valve is installed in air hose 4, a pressure is installed in total air supply tube 1
Force snesor 6, an air-conditioner control system 5 connect electric control valve, pressure sensor 6.
Specifically, electrically operated valve can be set at about 1/3 air outlet, certain air outlet sectional area, Xia Kai are occupied
Winter closes, so that winter is further reduced system air-out area, further increases wind speed (4 meter per seconds or so), airconditioning control system
System 5 increases the control point to electrically operated valve.
Specifically, the utility model can calculate air outlet static pressure needed for reaching 3.5 meter per second of wind speed first；The
Two steps are calculated and are always sent according to wind speed and according to heat load and the calculated institute's required airflow of the small temperature difference principle of big flow
The air supply areas of wind area and required reduction；Third step, according to the statistics of required air outlet static pressure and all air ports institute required airflow,
Determine the air quantity and total pressure of blower.
Specifically, air-conditioning motor can also be transformed, increase revolving speed, improves outlet air static pressure and air quantity.If (original motor without
The electric current rising space, then replace motor).Increase wind pressure sensor at main air supply tube simultaneously.
Further, it separates in air hose 4 and deflector is installed, so as to further reduce outlet air open area.
Further, it separates the outlet of air hose 4 and web plate is installed.
Further, air-conditioning box 2 is connected with air-conditioning water inlet pipe, air-conditioning return pipe, is equipped with control valve on air-conditioning return pipe.
Air-conditioner control system 5 connects control valve simultaneously.Air-conditioner control system 5 is existing system, can be realized by air-conditioner control system 5
Entirety control to operation of air conditioner.
Further, air-conditioner control system 5 is PLC control system.
In the specific implementation process of the utility model, to enable bottom absolute altitude in 6 meters or more of lower air outlet 1 to air port n
Enough that human height region will be sent under warm wind, air port wind speed should reach 3.5 meter per seconds or more.It is required, is counted according to air outlet velocity
Static pressure needed for mouth is blown is calculated, and then by air hose water force, obtains static pressure of blowing needed for total air supply tube 1.According to Wind Volume
Small temperature difference principle such as determines that the air blow and return temperature difference less than 5 degree, determines air-supply air quantity, according to air-supply air quantity and air outlet velocity requirement, really
Surely the value of air supply areas is reduced.According to the required air-supply air quantity and air-supply static pressure obtained, determine that 2 blower frequency of air-conditioning box is adjusted
Point such as depends merely on adjusting blower frequency and is unable to satisfy aforementioned claim, then considers more ventilating fan or adjustment blower belt wheel.
