Outside kitchen and toilet foul atmosphere discharge chamber that the utility model family expenses exhaust system is the poorest by indoor environment, thereby produce local decompression, make fresh air outside enter indoor, can guarantee that room air keeps flowing in 24 hours, will greatly improve IAQ.
The accompanying drawing explanation
Fig. 1 is the perspective view of the utility model exhaust system one specific embodiment.
Fig. 2 is the plan structure figure of the described specific embodiment of the utility model exhaust system.
Fig. 3 is the electric power system schematic diagram of the described ventilating fan of the utility model exhaust system.
Fig. 4 is the intelligent power supply control system logic chart of the described specific embodiment of the utility model exhaust system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
It is to support to rely on that the utility model family expenses exhaust system be take the furred ceiling that kitchen or toilet set up, intake stack and wind pipe is hidden in furred ceiling, at each blast pipe road junction, small-power, low noise ventilating fan are installed, indoor other regional air enter by kitchen or bathroom door 9, during air draft, kitchen or toilet window are for closing.As shown in Figure 1, at first wind pipe one-way air screen pack 4 is fixed on to wind pipe 3 outlets, then integrated intake stack 5 and the wind pipe 3 according to furred ceiling 6 standard production is fixed on kitchen or top, toilet, makes wind pipe 3 outlets just by the hole of getting on wall.Ventilating fan 1 and intake stack one-way air screen pack 2 installed successively and fixed, connect ventilating fan 1 power supply, start the Intelligent control electric way switch and debug each ventilating fan, and judgement can be accepted noise level.
As shown in Figure 2, if there was a mechanical failure or one-way air screen pack 2 needs to clean for ventilating fan 1, headspace 9 is with for convenience detach and replacing.
Be illustrated in figure 3 the electric power system schematic diagram of the described ventilating fan of the utility model exhaust system.Ventilating fan adopts lead-acid accumulator that the stable DC electricity is provided, and this exhaust system adopts solar panel charging and two kinds of patterns of family expenses grid charging, by intelligent control circuit, controls the pattern to charge in batteries.
Be illustrated in figure 4 the intelligent power supply control system logic chart of the described specific embodiment of the utility model exhaust system.This control circuit is preferentially selected the solar panel power supply, by solar panel is carried out to voltage sample, and when sampled voltage is greater than the storage battery power supply magnitude of voltage, to charge in batteries, otherwise, by the family expenses electrical network, be charge in batteries; When accumulator electric-quantity disconnects charging circuit higher than its capacity, otherwise, solar panel is carried out to voltage sample, which kind of pattern charging judgement adopts.
Specific embodiment
As shown in table 1, the living space of now take is 90m
2, the room height is that 2.8m, house volume are for being 252m
3the ordinarily resident family be that example is selected ventilating fan specification, battery specification, solar cell board parameter.
At first, determining the ventilating fan specification, owing to should reaching the capacity requirement, take again energy-conservation and noise problem into account, is that 1/h calculates by the indoor air-changing number of times, and total exhaust air rate of ventilating fan is 252m so
3/ h, i.e. 4.2m
3/ min, can select to install three air supply duct air drafts so.According to ventilating fan that sell market, selecting the exhaust air rate of ventilating fan is 1.5m
3/ h, rated power is 15W, rated voltage is 12V, rated current is 1.25A, producing noise is that 20dB can meet the demands, and 3 fans are about 24.77dB after the noise stack so, are much better than the requirement of People's Republic of China's city regional environment noise 1 class standard (being applicable to the zone of living, culture and education office is the master), be between daytime<55 decibels night<45 decibel.
Then, can select nominal voltage according to ventilating fan parameter and quantity is that 12V, nominal current are that 3.75A, capacity are 36AH(ampere-hour number) lead-acid accumulator.
Finally, determine solar panel, due to rechargeable solar battery voltage, must to be greater than 12V just chargeable, therefore can select peak power is that 40W, crest voltage are the polysilicon solar cell plate that 17.5V, peak point current are 2.25A, its size is long for 610mm() * 541mm(is wide) * 25mm(is thick).The lead-acid accumulator that is 36AH according to calculated capacity needs within 16 hours, be full of electricity in the situation that peak point current is 2.25A, is full of in electric situation and can powers 9.6 hours continuously for 3 ventilating fans.
The device parameter of the described specific embodiment of table 1 the utility model exhaust system is selected
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
