Description
Technical field
The utility model relates to vent cabinet, relates in particular to a kind of ventilation, heat energy double-balance safe ventilation cabinet.
Background technology
When traditional vent cabinet is worked in a certain room, reckon without balance and coordination problem with the scavenge pressure in this room, flow, cold and hot energy, therefore, easily cause the negative pressure in the room too big, cause a large amount of wastes of air conditioner cold-heat energy, air flow direction, size are also uncontrollable.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind ofly can prevent effectively that harmful poisonous gas escapes to cabinet in the experimentation and in the room, can save ventilation, the heat energy double-balance safe ventilation cabinet of energy again.
For achieving the above object, the utility model adopts following technical scheme: a kind of ventilation, heat energy double-balance safe ventilation cabinet, comprise cabinet, air one air heat exchanger, pressure fan, exhaust blower and passage, it is characterized in that cabinet is provided with overhead door, described air one air heat exchanger places in the cabinet, it has two groups of heat exchange gas channels, one group of gas channel is an air-supply passage, the outer new wind inlet channel of its terminating room, corresponding with it another termination is to the air-supply passage of indoor air-supply; Another group gas channel is an air exhaust passage, air draft passage and cabinet air draft passage in its terminating room, corresponding with it another termination is to the air exhaust passage of outdoor air draft, and pressure fan places new wind inlet channel, and exhaust blower places the air exhaust passage to outdoor air draft.
In the such scheme, be provided with the damper of regulating the air inlet size in indoor air draft passage porch, cabinet is provided with the overhead door position sensor, the overhead door position sensor is by the rotating speed and the damper size of controller control exhaust blower, overhead door is opened big more, the exhaust blower rotating speed is high more, and the damper aperture is more little.
In such scheme, the rotating speed of described pressure fan is by being located at indoor pressure difference transducer control.
In such scheme, described air-air heat exchanger also joins with the cabinet air-supply passage of blowing in cabinet with when the air-supply passage of indoor air-supply joins.
When vent cabinet is worked, the size of exhaust air rate is by opening degree (high and low position) decision of cabinet overhead door in its cabinet, overhead door is opened big more (position is high more), the overhead door position sensor reduces indoor air draft passage porch damper aperture by controller, increasing exhaust machine rotating speed and air quantity, pressure fan also increases air output under the effect of pressure difference transducer, negative pressure in the room is remained in some scopes, and make the air output minimum, meanwhile, because air-air heat exchanger carries out heat exchange with exhaust and air inlet, make heat energy in the exhaust obtain reclaiming, in ventilation the temperature fluctuation in room little, and can fully replenish fresh air.
The utility model can use minimum air quantity to satisfy the instructions for use of vent cabinet, and have tracing property, it can effectively be controlled in the experimentation and be harmful to, toxic gas escapes to cabinet and in the room, saves the operation energy of blower fan, make the discharge loss of cold and hot amount minimum, have fabulous energy-saving effect.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, but protection domain of the present utility model is not so limited.
With reference to Fig. 1, the utility model is basically by cabinet 1, air-air heat exchanger 4, pressure fan 2, exhaust blower 3 and passage are formed, wherein, cabinet 1 is provided with overhead door 6 and overhead door position sensor 8, described air-air heat exchanger 4 places cabinet 1 internal upper part, constitute by metal level that is staggeredly arranged in parallel and non-metallic layer, adopt CN02290456.5 air fixed-plate heat exchangers patented technology, it has two groups of interlaced arrangement and heat exchange gas channel independently, these two groups of gas channels form between metal level and non-metallic layer, one group of gas channel is an air-supply passage, the outer new wind inlet channel 9 of its terminating room, corresponding with it another termination is to the air-supply passage 10 of indoor air-supply, at the also other cabinet air-supply passage of blowing in cabinet that is connected on the air-supply passage 10 of indoor air-supply; Another group gas channel is an air exhaust passage, air draft passage 11 and cabinet air draft passage 12 in its terminating room, corresponding with it another termination is to the air exhaust passage 13 of outdoor air draft, and pressure fan 2 places new wind inlet channel 9, and exhaust blower 3 places the air exhaust passage 13 to outdoor air draft.Be provided with the damper 5 of regulating the air inlet size in cabinet air draft passage 12 porch, overhead door position sensor 8 is by the rotating speed and damper 5 sizes of controller control exhaust blower 3, overhead door 6 is opened big more, and exhaust blower 3 rotating speeds are high more, and damper 5 apertures are more little.The rotating speed of described pressure fan 3 is by being located at 7 controls of indoor pressure difference transducer.
When overhead door 6 moved up and down, the exhaust air rate of damper 5 and exhaust blower 3 also changed size thereupon.When the room negative pressure changes, be located at indoor pressure difference transducer 7 air quantity of pressure fan 2 is also changed thereupon, thereby make indoor negative regulation in certain scope.
When overhead door 6 by height to low when mobile, exhaust blower 3 also reduces exhaust air rate, damper 5 leaves greatly simultaneously, and make the part air draft without vent cabinet inside directly by indoor be discharged into outdoor, otherwise, air draft is passed through earlier in the cabinet, be discharged into outdoor again.
Air-the air heat exchanger 4 that is positioned at cabinet can make air draft and air-supply carry out the wet exchange of heat, reclaims the heat energy in the air draft, reaches the purpose of stablizing temperature in the room.
