Description
Technical field
The utility model relates to a kind of air conditioner ventilating system, particularly a kind of air conditioner ventilating system with self hang down type blinds air exhausting device.Belong to the HVAC technical field.
Background technology
At present, in a lot of large spaces, should design air conditioner ventilating system and design the fire-fighting smoke evacuation system again.The function that people often adopt Electric air valve to satisfy is between the two changed.Under the air conditioner ventilation operating mode, Electric air valve is opened, and system carries out the malleation exhaust; Under the fire-fighting operating mode, Electric air valve is closed, and system discharges fume.But there is following shortcoming in this method of Electric air valve conversion of utilizing: 1, because Electric air valve easily produces fault, therefore cause the reliability of system to reduce.2, system architecture is complicated, and cost is higher.3, cause easily that under the influence of outdoor specific wind direction air-flow pours in down a chimney.
The utility model content
The purpose of this utility model, be in order to overcome existing air conditioner ventilation and there is the shortcoming that reliability is low, system cost is high in the fire-fighting smoke evacuation system, a kind of air conditioner ventilating system with self hang down type blinds air exhausting device is provided, and this system has reliability height, characteristics that system cost is low.
The purpose of this utility model can reach by following technical solution:
The air conditioner ventilating system of band self hang down type blinds air exhausting device comprises air-conditioned room, and its design feature is: also comprise outdoor air-conditioner and fire-fighting fume extractor; The air inlet of outdoor air-conditioner is communicated with outdoor air, the air outlet of outdoor air-conditioner, return air inlet respectively with the internal communication of air-conditioned room; The suction opeing of fire-fighting fume extractor is communicated with the fire-fighting exhaust opening of air-conditioned room, and the sidewall of air-conditioned room is provided with exhaust outlet, is provided with the self hang down type blinds at this exhaust outlet place.
The self hang down type blinds can be opened or close automatically according to the variation of indoor and outdoor pressure reduction; When being in malleation, the self hang down type blinds is opened automatically when indoor, carries out exhaust to indoor; When being in negative pressure, the self hang down type blinds is closed automatically when indoor.
The purpose of this utility model can also reach by following technical solution:
A kind of embodiment of the present utility model is: the fire-fighting fume extractor can be made of blower fan.
A kind of embodiment of the present utility model is: described exhaust outlet has two and be arranged on the top of air-conditioned room sidewall at least.
A kind of embodiment of the present utility model is: the self hang down type blinds can be made of framework and some blades, and the end of described blade and framework flexibly connect, and forms the free style rotational structure.
A kind of embodiment of the present utility model is: can be provided with rainproof air intake blinds at the air inlet place of air-conditioner.
The beneficial effects of the utility model are:
The utility model is owing to install the self hang down type blinds in air-conditioned room, the self hang down type blinds can be opened or close automatically according to the variation of indoor-outdoor air pressure differential; It can satisfy the function conversion between air conditioner ventilation and the fire-fighting smoke evacuation, realizes the purpose of the automatic conversion of function between air conditioner ventilation and the fire-fighting smoke evacuation.Have simple in structurely, reduce the cost of system and increase system reliability, make that native system has efficiently, practicality, energy-conservation beneficial effect.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Specific embodiment 1:
With reference to Fig. 1, present embodiment comprises air-conditioned room 1, outdoor air-conditioner 2 and fire-fighting fume extractor 4; The air inlet 21 of outdoor air-conditioner 2 is communicated with outdoor air, the air outlet 22 of outdoor air-conditioner 2, return air inlet 23 respectively with the internal communication of air-conditioned room 1; The suction opeing of fire-fighting fume extractor 4 is communicated with the fire-fighting exhaust opening 11 of air-conditioned room 1, and the sidewall of air-conditioned room 1 is provided with exhaust outlet, is provided with self hang down type blinds 3 at this exhaust outlet place.Be provided with a rainproof air intake blinds 5 at air inlet 21 places of air-conditioner 2.
In the present embodiment, smoke evacuation air port 11 is arranged on the top of air-conditioned room 1, and smoke evacuation air port 11 is connected with fume extractor 4 suction opeings of communication chamber outer air.Be provided with two exhaust outlets in the side wall upper part of air-conditioned room 1 and a self hang down type blinds 3 respectively be installed along described exhaust outlet place.Fire-fighting fume extractor 4 is made of blower fan.Self hang down type blinds 3 is made of framework and some blades, and the end of described blade and framework flexibly connect, and forms the free style rotational structure.
Operation principle:
With reference to Fig. 1, under the air conditioner state, outdoor new wind enters air-conditioner by rainproof air intake blinds, send in the air-conditioned room by air outlet again, this moment Pn＞Pw, (Pw represents outside wind pressure; Pn represents room pressure), the self hang down type blinds is outwards opened automatically, carries out exhaust to indoor; Under fire fighting state, air-conditioner is closed, and smoke exhaust fan is opened, at this moment, Pn＜Pw, the self hang down type blinds is closed automatically, and the smoke evacuation air port is opened and is discharged fume to indoor.This shows that the self hang down type blinds can be opened or close automatically according to the variation of indoor and outdoor pressure reduction, finishes the switching of two kinds of operating modes.
Other embodiment:
The quantity of described self hang down type blinds 3 is 1,3,4,5 or 6.Change the quantity and the installation site of self hang down type blinds 3 or adopt the fire-fighting fume extractor of other types all to belong to protection domain of the present utility model.
