Preferably, further include fresh air valve, and the setting of fresh air valve is mutual in aeration device air inlet and the external world
The position of connection.Fresh air volume can be determined according to indoor carbon dioxide concentration, by controlling the opening degree of fresh air valve, be realized
In the minimum air quantity for meeting hygienic requirements.
Preferably, valve is motor-driven valve.Motor-driven valve is i.e. by Electric Actuator control valve, to realize valve
Electronic on and off.
Preferably, motor-driven valve is connect with building automatic control device.It is included in automatic control system, is existed in real time
Line monitors, and realizes the automation control of air-conditioning system standard.
Preferably, aeration device is AHU systems.AHU systems, that is, air-treatment unit (Air Handling
Unit) have many advantages, such as to handle that air quantity is big, air quality is high, energy saving, be especially suitable for large spaces such as market, exhibition center, airport, big
The system of flow of the people.
Preferably, air exhausting device is exhaust fan, and exhaust fan can be centrifugal fan, axial fan etc.
The various wind turbines that can reach exhaust effect, exhaust fan achieve the effect that ventilation by air draft.
Preferably, aeration device and air exhausting device are arranged in Air Conditioning Facilities, are convenient for daily maintenance management.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the invention are as follows：This
The existing air-conditioned structure type of invention change is realized when transition season uses air-conditioning system, without starting operation refrigeration system,
Cooling processing only can be carried out to interior by the nice and cool fresh air in outdoor.In addition, the present invention provides fresh air comprehensively in transition season,
It ensure that the air pleasant degree of indoor environment；And maximally utilise outdoor fresh air and cooling processing is carried out to interior, reduce
System operation energy consumption.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
The present embodiment discloses a kind of air conditioning duct system that can reduce operation energy consumption, as shown in Figure 1, including aeration device, newly
The air inlet of wind apparatus is in communication with the outside, and air outlet is connected to room；Further include air exhausting device, the air inlet and room of air exhausting device
Between be connected to, air outlet is connected to the air inlet of aeration device, and air outlet is also in communication with the outside.
Specifically, as shown in Figure 1, the present embodiment further includes the air inlet valve for being used in transition season, and air inlet valve
Door is arranged in the position that air exhausting device air outlet and aeration device air inlet are interconnected.The present embodiment further includes in air-conditioning
The valve for air exhaust that season uses, and valve for air exhaust is arranged in air exhausting device air outlet and extraneous interconnected position.This implementation
Example further includes the fresh air valve for controlling fresh air volume, and the setting of fresh air valve is interconnected in aeration device air inlet and the external world
Position.Valve is motor-driven valve, and motor-driven valve is connect with building automatic control device, and air conditioner is realized using valve conversion and control
Group all-fresh air operation.When valve is not included in building automatic control system control, common manual regulating valve may be set to be
It substitutes.
Specifically, as shown in Figure 1, aeration device is AHU systems.Air exhausting device is exhaust fan.Aeration device and air draft
Device is arranged in Air Conditioning Facilities；Such as without Air Conditioning Facilities, other equal spaces can also be set in room furred ceiling.Air-conditioned room has
Room I and room II, if desired, more rooms can be arranged.Aeration device air outlet and air exhausting device air inlet with every room
Between be connected to, aeration device and air exhausting device concentrated setting, and by pipeline by aeration device air outlet and air exhausting device air inlet
It is connected to room, advantageously reduces number of devices, save input cost.
There are two types of air-conditioner wind operational modes for the present embodiment tool, that is, are included in the air conditioning mode of air-conditioning season operation and in transition
The fresh air pattern of season operation.It is described in detail below：
One, air conditioning operating mode
In air-conditioning season, exhaust fan and AHU systems is opened, and the refrigeration system in air-conditioning system must be opened, turned off
Valve for air exhaust.The operating path of wind system is in air conditioning mode, and outdoor fresh air enters through AHU system air inlets in air-conditioning system
Refrigeration system is delivered to by AHU system air outlets in room again after carrying out air-treatment；Then, room air is through exhaust fan
Air inlet, then the air outlet by being connected with AHU system air inlets enter the refrigeration in air-conditioning system, and merging treatment is mixed with fresh air
It is delivered in room by AHU system air outlets again afterwards.Citing：The air output of air-conditioning system is 30000m3/ h, wherein outdoor new
Air quantity is 3000m3/ h, air draft return air amount are 27000m3/ h, then the actual provision fresh air volume in room is 3000m3/h。
Two, fresh air operational mode
In transition season, exhaust fan and AHU systems are opened, and the refrigeration system in air-conditioning system need not be opened, then close
Close air inlet valve.The operating path of wind system is in fresh air pattern, and outdoor fresh air is after AHU system air inlets, directly by AHU systems
System air outlet is delivered in room；Then, room air directly drains into room through exhaust fan air inlet by exhaust fan air outlet
Outside.Citing：The air output of air-conditioning system is 30000m3/ h, since air inlet valve has been switched off, then fresh air volume is also 30000m3/
h；Exhaust fan exhaust air rate is 30000m3/ h, then actual provision fresh air volume in room is 30000m3/ h, fresh air volume are that air conditioning mode is new
10 times of air quantity.
Since in the operational mode, room actual provision fresh air volume does not include indoor return air air quantity, therefore realizes to greatest extent
Outdoor fresh air is introduced, room air is cooled down using outdoor fresh air.Since outdoor temperature is relatively indoor relatively low, may be implemented to be not turned on
Many current consuming apparatus such as chilled water, cooling water water pump, air conditioner refrigerating host in air-conditioning refrigeration system.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
