The air-conditioning system of Zhongting building
Technical field
The utility model belongs to the air-conditioning system technical field, is specifically related to a kind of air-conditioning system of Zhongting building.
Background technology
The Zhongting building is a kind of building structure that is similar to courtyard, and its characteristics are very obvious, have good daylighting and circulation of air.Yet, the following problem of air-conditioning system ubiquity of present Zhongting building:
Because the density of cold air is bigger, can nature flow downward, and hot-air density is less, can upwards flow by nature.In Zhongting building, the top layer temperature that these reasons will cause building is high, and near-bottom temperature is low, the phenomenon of " upper heat and lower cold " occurs.Summer in order to keep the nice and cool of top layer, will cause near-bottom temperature low excessively; In order to keep the warm of bottom, will cause the top layer temperature too high in the winter time.
The utility model content
The utility model embodiment provides a kind of air-conditioning system of Zhongting building, has solved the technical problem of existing Zhongting building ubiquitous " upper heat and lower cold ".
For achieving the above object, the embodiment of the utility model adopts following technical scheme:
The air-conditioning system of this Zhongting building, (Air Handing Unit, AHU) unit, and the air supply duct that links to each other with said AHU unit, said air supply duct are communicated to each layer of Zhongting building, and all are provided with air outlet at every layer to comprise air-treatment; On every layer said air outlet, be equipped with the variable air rate valve, and the temperature sensor that links to each other with each said variable air rate valve.
Preferably, the air-conditioning system of this Zhongting building also comprises the return air duct that links to each other with said AHU unit, and said return air duct is communicated to each layer of Zhongting building, and all is provided with return air inlet at every layer, is used for sending the air of each layer back to the AHU unit.
Compared with prior art, have following advantage in the technique scheme that the utility model provided:
Be arranged on variable air rate valve on every layer the air outlet and can realize the independent regulation of each layer air quantity: every layer temperature sensor is measured the real time temperature of each floor respectively; And separately according to the aperture of the variable air rate valve of this layer of adjustment of this layer; Thereby the temperature of each layer of Zhongting building is consistent, has solved the technical problem of " upper heat and lower cold " of the existence of existing Zhongting building.
In summer, when air-conditioning system is sent cold wind to each layer, be positioned at which floor of building top, can suitably increase air quantity according to temperature separately; Be positioned at which floor of construction bottom, can suitably reduce air quantity according to temperature separately, thereby the temperature of each layer is consistent.
In the winter time, when air-conditioning system is sent warm braw to each layer, be positioned at which floor of building top, can suitably reduce air quantity according to temperature separately; Be positioned at which floor of construction bottom, can suitably increase air quantity according to temperature separately, thereby the temperature of each layer is consistent.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the air-conditioning system of the Zhongting that embodiment the provided building of the utility model.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not paying creative work belongs to the scope that the utility model is protected.
As shown in Figure 1, the air-conditioning system of the Zhongting building that the utility model embodiment is provided comprises air-treatment (Air Handing Unit; AHU) unit 1; And the air supply duct 2 that links to each other with AHU unit 1, air supply duct 2 is communicated to each layer of Zhongting building, and all is provided with air outlet at every layer; On every layer air outlet, be equipped with variable air rate valve 21, and the temperature sensor 22 that links to each other with each variable air rate valve 21.
Wherein, AHU unit 1 can be arranged in the machine room of any one deck of Zhongting building.As a preferred version; The air-conditioning system of this Zhongting building also comprises the return air duct (not shown) that links to each other with AHU unit 1; The structure of return air duct is identical with air supply duct 2; Also be communicated to each layer of Zhongting building, and all be provided with return air inlet, be used for sending the air of each layer back to AHU unit 1 at every layer.
Be arranged on variable air rate valve 21 on every layer the air outlet and can realize the independent regulation of each layer air quantity; Every layer temperature sensor 22 is measured the real time temperature of each floor respectively; And separately according to the aperture of the variable air rate valve 21 of this layer of adjustment of this layer; Thereby the temperature of each layer of Zhongting building is consistent, has solved the technical problem of " upper heat and lower cold " of the existence of existing Zhongting building.
In summer, when air-conditioning system is sent cold wind to each layer, be positioned at which floor of building top, can suitably increase air quantity according to temperature separately; Be positioned at which floor of construction bottom, can suitably reduce air quantity according to temperature separately, thereby the temperature of each layer is consistent.
In the winter time, when air-conditioning system is sent warm braw to each layer, be positioned at which floor of building top, can suitably reduce air quantity according to temperature separately; Be positioned at which floor of construction bottom, can suitably increase air quantity according to temperature separately, thereby the temperature of each layer is consistent.
In addition, the top layer temperature of building also can change along with the variation of weather.Because therefore the temperature that the mode that the air-conditioning system that the utility model embodiment provides adopts dynamic real-time to regulate is regulated each layer can also well solve the problem that the top layer temperature receives weather effect.
The air-conditioning system that the utility model embodiment provides has solved the Zhongting building problem of " upper heat and lower cold " of existence all the time.Set up variable air rate valve and corresponding building automatic (Building Automation at every layer air outlet; BA) control appliance; The variable air rate technology is applied to the air-conditioning system of Zhongting building; The temperature of each layer of mode independent regulation of regulating with dynamic real-time has simple characteristics, and advantages of high practicability and reliability.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
