Description

Elevator fresh air purifying system

Technical field

The utility model relates to about improving the system of air quality in the elevator.

Background technology

Elevator is as the density of personnel height, and the contact distance is near, uses a frequent public place, is important flow of personnel passage in modern high-rise building.At present, the wind circulation in the elevator also just is limited to the air inerchange in air and the ladder in the elevator hoistways, so the fresh air that only depends on the switch door to obtain is difficult to guarantee the air quality in the elevator, says nothing of the peak load conditions on and off duty that the stream of people concentrates.Air quality in the cab is poor, though the time of taking is not very long, but allows the people produce the very significantly phenomenon of Human Physiology discomfort, has had a strong impact on people's healthy and mood.During 2003 SARS, take elevator and become a very awkward thing especially.

The quality of air quality directly influences people's health.Improving the effective method of room air in the prior art is means such as ventilation, disinfection, air filtration purification.Because ventilation can thoroughly solve the ratio of the air effective ingredient of sealing indoor environment, the air of transferring the pollution improves the overall situation of room air in indoor delay.Ventilation is that of IAQ improvement is basic substantially.

In addition, studies show that: air purifier makes air pass the high-efficiency air filtering layer by supply ventilating fan, reaches the purification purpose thereby pollutants separated from air.Also eliminate foreign flavor indoors in addition, strengthen bactericidal effect, make the germ survival rate almost nil by supplementary meanss such as ultraviolet rays by the high-efficiency catalytic activity charcoal.

To provide an atmosphere with fresh air in order giving in the elevator cage, mainly to have adopted following technical scheme at present:

1, elevator air conditioning system: air conditioner for elevator is a kind of demand that occurs along with the increase of mansion construction in recent years.But the main effect of air conditioner for elevator is the adjusting that is used for temperature in the elevator cage, and suitable new wind also is that the unclean wind circulation in the elevator hoistways uses.The effect that is adjusted in the cooling of performance when summer, air was sultry of temperature feels it is apparent in view to the comfort level of human body in the elevator; But can not change bacterium in the elevator cage air, germ, can suck the bad index of air such as oxygen content in particles in suspension, the air.Elevator cage internal cause space is narrow and small, and density of personnel is high, and it is extremely abominable that air quality remains.

2, cab fan: this mode just plays the effect of cab cooling, and action effect is not obvious.More do not have the effect that improves the cab air quality.

The purpose of invention

The purpose of this utility model provides a kind of elevator fresh air purifying system that improves air quality in the elevator, by in elevator, adopting this utility model system, can be for sufficient fresh up-to-standard air be provided in the elevator, make the elevator occupant can not find phenomenon such as anoxic, unhappy, peculiar smell and worry the propagation of germ.Thoroughly improve the traveling comfort and the wholesomeness of elevator ride.Improve the service quality of mansion simultaneously.

The technical solution adopted in the utility model is such, and promptly a kind of elevator fresh air purifying system comprises elevator hoistways and is positioned at the elevator cage of hoistway; It is characterized in that: have supply air duct at the top of elevator hoistways, this supply air duct is communicated with by breeze fan and the filter air port of getting outdoor with being arranged on roof, the bottom of elevator hoistways has the exhausting air channel, and this exhausting air channel connects the exhausting blower fan by filter; The pure and fresh main frame of new wind is installed at the top of elevator cage, has the air-blending storehouse in the main frame, its bottom is communicated with elevator cage by balance diffusion air port, and its top is communicated with elevator hoistways by blower fan and filter.

The principle of work of said system is such: send into new wind from the external world to elevator hoistways, hoistway bottom exhausting forms new wind airiness path in elevator hoistways.The elevator cage that moves in elevator is in new distinguished and admirable passband, solves the present situation that elevator does not have new wind; The pure and fresh main frame of new wind is installed on the elevator cage top, by filtering, sterilize, add negative oxygen ion and the air of handling being carried out the adjustment of temperature and humidity, make it reach the most comfortable air quality state the new wind in the hoistway along with the Various Seasonal human feeling.Control part can be set the various fixed pattern by Programmable Logic Controller, uses the Infrared remote controller control operation; Further but sensor installation realizes that automatic guidance reaches predetermined value, and sets up the digital demonstration of air parameter at the cab inwall, allows passenger intuitively see real-time air quality state.

The beneficial effects of the utility model are very tangible, promptly by links such as ventilation, air sterillization and air-pollution controls, the air in the elevator cage are handled, and make it reach " IAQ standard " national standard.It can improve elevator ride personnel eye, nose, pharynx, throat position has excitement, headache, fatiguability, expiratory dyspnea, skin irritatin, drowsiness, asthma, uncomfortable in chest, headache, weak, catch a cold easily, dispersion attention, non-special symptoms such as bad reaction such as fatigue easily.Improve cerebral function, enhancing body immunity enhances metabolism, and regulates nervous function, allaying tiredness, and the bacterium of inhibition, viral growth are arranged, remove the air peculiar smell, effects such as clean air.
