Description
Technical field
Field of central air-conditioning is the utility model is related to, specifically, is related specifically to a kind of for the clean system of center air
The air circulation a-b box of system.
Background technology
A set of independent air processing system that VMC is made up of supply air system and exhaust system, it is divided into duct type
VMC and without two kinds of pipeline VMC.Duct type VMC is made up of new blower fan and pipe fitting, passes through new blower fan
Clean room outer space conductance enters interior, is discharged room air by pipeline；Without pipeline VMC by Fresh air handling units into, equally by
New blower fan clean room outer space conductance enters interior, while is discharged foul indoor air by breathing treasured.Comparatively duct type fresh air
System uses because quantities is more suitable for greatly industrial or large area Office Area, and without pipeline VMC because easy for installation,
It is more suitable for family's use.
VMC can reach the purpose to purify the air of a room with indoor and outdoor air exchange, but be followed in not switching to
The function of ring.
Utility model content
The purpose of this utility model is to be directed to deficiency of the prior art, there is provided one kind is used for center air clean system
Air circulation a-b box, to solve problems of the prior art.
The technical problem that the utility model solves can be realized using following technical scheme：
A kind of air circulation a-b box for center air clean system, including housing, are arranged in the housing
Fresh air duct is with purification air channel and for connecting fresh air duct and purifying the connection air channel in air channel；
The fresh inlet connected with fresh air duct and the indoor wind connected with purification air channel are provided with the side of the housing
Outlet, the fresh air outlet connected with fresh air duct and the indoor air intake connected with purification air channel are provided with the opposite side of the housing
Mouthful；
The fresh air duct is provided with the first motor and by the first motor-driven fresh air valve, the purification air channel
Second motor is installed and the 3rd motor, Yi Jiyou are provided with by the second motor-driven purification valve, the connection air channel
3rd motor-driven connecting valve；
Close open is mounted in the fresh air valve, purification valve and the open position of connecting valve and closed position
Close.
Compared with prior art, the beneficial effects of the utility model are as follows：
The varying environment condition that the utility model is detected by IAQ, control the rotation of three motors.Intelligence
The outdoor room air that switches to of energy exchanges, or indoor air circulation purification.
Brief description of the drawings
Fig. 1 is the schematic diagram of air circulation a-b box described in the utility model.
Fig. 2 is the schematic diagram of air exchange pattern in indoor and outdoor described in the utility model.
Fig. 3 is the schematic diagram of indoor circulation purification pattern described in the utility model.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
Referring to Fig. 1, a kind of air circulation a-b box for center air clean system described in the utility model, including
Housing 1, the fresh air duct 2 being arranged in the housing 1 and purification air channel 3 and for connect fresh air duct 2 and purification air channel
3 connection air channel 4；
The fresh inlet 21 connected with fresh air duct 2 and the room connected with purification air channel 3 are provided with the side of the housing 1
Interior wind outlet 31, export 22 provided with the fresh air connected with fresh air duct 2 in the opposite side of the housing 1 and connect with purification air channel 3
Logical indoor air inlet 32；
The fresh air duct 2 is provided with the first motor 23 and the fresh air valve 24 driven by the first motor 23, described net
Wind transmission road 3 is provided with the second motor 33 and the purification valve 34 driven by the second motor 33, and the connection air channel 4 is provided with
3rd motor 41 and the connecting valve 42 driven by the 3rd motor 41；
It is mounted on connecing in the fresh air valve 24, purification valve 34 and the open position of connecting valve 42 and closed position
Nearly switch.
The utility model opens or closes different valves according to the difference of air ambient condition.
Referring to Fig. 2, as the CO of the air of IAQ Acquisition Instrument collection2Concentration over-standard, or air cleaning system
Open half an hour, the parameter of air quality Acquisition Instrument collection does not reach standard, and air circulation a-b box is switched to indoor and outdoor
Air exchange pattern.Now the fresh air valve of air circulation a-b box or so and purification valve are open-minded, and middle connecting valve is closed
Close.
Referring to Fig. 3, as the CO in air2Concentration is relatively low, other air index (formaldehyde, TVOC, PM2.5) content overproofs
When, air circulation a-b box is switched to indoor circulation purification pattern, and fresh air valve and purification valve are closed, middle connecting valve
Open.When air index is normal, three valves are all closed.
General principle and principal character of the present utility model and of the present utility model excellent has been shown and described above
Point.It should be understood by those skilled in the art that the utility model is not restricted to the described embodiments, above-described embodiment
Simply illustrate principle of the present utility model with described in specification, do not depart from the premise of the spirit and scope of the utility model
Under, the utility model also has various changes and modifications, and these changes and improvements both fall within claimed the utility model model
In enclosing.The utility model requires protection scope is by appended claims and its equivalent thereof.
