Abstract
The present invention provides a ventilation device which comprises a casing, a heat exchanger, an air supply passage, an exhaust passage, an air supply fan and an exhaust fan. The present invention is characterized in that the present invention also comprises a fast exhaust passage, an exhaust air throttle, a fast air supply passage and an air supply air throttle; the fast exhaust passage is formed in the space between the top surface of the heat exchanger and the inner wall of the casing, and is used for causing indoor air not to pass through the heat exchanger but to directly exhaust outdoors; the exhaust air throttle is arranged in the bifurcation position of the exhaust passage and the fast exhaust passage, and the bifurcation position is at one side of the heat exchanger, which is adjacent to the interior of a room; when the exhaust air throttle is opened, the fast exhaust passage is opened, and the exhaust passage is closed; when the exhaust air throttle is closed, the fast exhaust passage is closed, and the exhaust passage is opened. The present invention has the advantages that the fast exhaust passage and the fast air supply passage are provided, the indoor air can be fast exhausted outdoors, and outdoor air can be fast sucked indoors.
Description
Technical field
The present invention relates to a kind of compound ventilation air-changing device.
Background technology
People live in the not smooth interior space of ventilation, because continuous oxygen intake gives off carbon dioxide, the oxygen content in the room air can be fewer and feweri, and carbon dioxide content can get more and more.At this moment, often need to utilize an air interchanger that indoor contaminated air and outdoor fresh air are in time changed.
The simplest air exchanging method is to utilize a pressure fan forcibly to discharge indoor contaminated air outdoor.The shortcoming of this air exchanging method is, outdoor cold air or hot-air can cause the rapid variation of indoor temperature by in the direct inlet chamber in slit of door and window, and one waste energy, and the two feels under the weather the people.In addition, it is tighter that indoor door and window is closed ground, and outdoor fresh air in the inlet chamber, might cause interior space oxygen content low excessively swimmingly, makes to be in indoor personnel and to feel anoxic.And this air exchanging method can not be regulated the humidity of room air.
In order to address the above problem, people develop a kind of air interchanger that has heat exchanger.When this air interchanger was worked, indoor contaminated air at first changed its temperature by heat exchanger, just is discharged to outdoor then; And outdoor fresh air at first changes its temperature by heat exchanger, then just in the inlet chamber.
As shown in Figure 1, this structure that has the air interchanger of heat exchanger is: be provided with in the casing 1 outdoor air is introduced indoor air supply channel 10 and will be room air row to outdoor exhaust passage 30, air supply channel 10 is arranged in a crossed manner with exhaust passage 30, and its infall is provided with heat exchanger 5.
The outermost end of described air supply channel 10 is and the indoor air supply inlet that is communicated with 11 that its inner terminal is and the indoor air supply outlet that is communicated with 13; The inner terminal of described exhaust passage 30 is and the indoor exhaust entrance that is communicated with 31 that its outermost end is and the outdoor air exit that is communicated with 33.
Described air supply channel 10 and exhaust passage 30 are that the center is cross-section up and down with the inner space of casing 1 with heat exchanger 5, and the two does not disturb mutually.Be that air supply channel 10 is that the center is formed by dividing plate 10a that extends to air supply inlet 11 and the dividing plate 10b that extends to air supply outlet 13 with heat exchanger 5; To be the center with the heat exchanger formed by dividing plate 30a that extends to exhaust entrance 31 and the dividing plate 30b that extends to air exit 33 for exhaust passage 30.
The inboard of the air supply outlet 13 of described air supply channel 10 is provided with outdoor air forcibly is drawn into indoor air-feeding ventilator 15; The inboard of the air exit of described exhaust passage 30 is provided with room air forcibly is discharged to outdoor scavenger fan 35.
Described heat exchanger 5 is that two corners are supported by casing 1 up and down, and its corner, left and right sides is by the membrane support of dividing air supply channel 10 and exhaust passage 30.Be formed with the exhaust slit 5b that air feed slit 5a that several and air supply channel 10 be interconnected and several and exhaust passage 30 are interconnected on the heat exchanger 5.Separated by dividing plate between these air feed slit 5a and the exhaust slit 5b, the surface of air feed slit 5a and exhaust slit 5b is provided with the higher heat exchange membranes (not shown) of one deck heat exchanger effectiveness.
Below the above-mentioned course of work that has the air interchanger of heat exchanger is illustrated:
When room air pollution arrives to a certain degree, start scavenger fan 35, under the driving of scavenger fan 35, room air by the exhaust slit 5b of heat exchanger 5, is arranged to outdoor from air exit 33 by exhaust entrance 31 and then exhaust passage 30 again.
Meanwhile, start air-feeding ventilator 15, under the driving of air-feeding ventilator 15, outdoor fresh air enters air supply channel 10 by air supply inlet 11, passes through the air feed slit 5a of heat exchanger 5 again, in air supply outlet 13 inlet chambers.
In said process, room air and outdoor air by heat exchanger 5 carry out heat exchange on heat exchange membranes.Specifically, the heat exchange that takes place in heat exchanger 5 is to utilize the temperature of room air or outdoor air to reduce to the waste heat that makes the condensed water that is produced below the dew point to come heating clamber outer air or room air to carry out.
The advantage of above-mentioned air interchanger is, in the outdoor air inlet chamber before and room air row before outdoor, all to carry out a heat exchange by heat exchanger 5, therefore in scavenging period, indoor temperature can sharply not rise or sharply decline.
But above-mentioned air interchanger also has following shortcoming simultaneously: since room air must be at first undertaken just being discharged to after the heat exchange by heat exchanger 5 outdoor, so can not fast will indoor contaminated air discharge.For example, perhaps indoor when leaking out a large amount of pernicious gas when indoor food spoilage produces strong corrupt smell, this air interchanger just can not satisfy its requirement of discharge fast.
In addition and since outdoor air must be at first by heat exchanger 5 carry out after the heat exchange could inlet chamber in, so in needs make the outdoor air inlet chamber fast the time, this air interchanger obviously can not be satisfied the demand.

Shown in Fig. 4 b, when the needs air interchanger to indoor when taking a breath fast, can the piston 65 of air feed air throttle be retreated to greatest extent from hydraulic cylinder 70 by control device, connecting rod 63 drives valve plate 61 counterclockwise to rotation, when valve plate 61 contacts with dividing plate 10a, just air supply channel 10 is closed, simultaneously quick air supply channel 20 is opened.Meanwhile, by control device the piston 55 of exhaust air throttle is retreated to greatest extent from hydraulic cylinder, connecting rod 53 drives valve plate 51 clockwise directions rotation, when valve plate 51 contacts with dividing plate 30a, just exhaust passage 30 is closed, simultaneously quick exhaust passage 40 is opened.
At this moment, start suction fan 15, outdoor air enters quick air supply channel 20 by air supply inlet 11, directly by in the air feed exhaust outlet 13 quick inlet chambers.Meanwhile, start exhaust fan 35, room air just enters exhaust passage 40 by exhaust entrance 31, directly arranges to outdoor fast by air exit 33.
