Description

A kind of air-conditioning box and operation method thereof controlling haze sky room air pollution
Technical field
The present invention relates to central air-conditioning system technical field, particularly a kind ofly haze sky indoor accelerated test is polluted to the air-conditioning box and operation method thereof that control.
Background technology
Haze weather has just like become keyword very active on recent months media, and China is the with serious pollution country of PM2.5, and overall in PM2.5 high pollution situation, coastal area is polluted particularly remarkable.And along with the development of economy, increasing sharply of city automobile recoverable amount, urban atmosphere small particles thing proportion constantly increases, and more should pay close attention to the harm of PM2.5 to health.But most people 70% ~ 90% time spend in indoor, the investigation of CCTV.com website also shows: have the people of nearly 1/5 to stay more than 8h under central air conditioning environment every day.Therefore the Center for Disease Control thinks that the harm of room air pollution to human body exceedes outdoor air pollution.And expert points out that indoor air particulate matter pollution accounts for 76% of whole room air pollution, and developing country is even more serious than developed country.Pollute even more important on the impact of health so control indoor accelerated test.
Tradition central air-conditioning system controls indoor particle substrate concentration by arranging air cleaner, but in fact, outdoor particle concentration is constantly change, especially in some special haze weather, outdoor particle concentration is ten several times under normal circumstances, so still utilize traditional air conditioner filtration system in this period, then can not particle effectively outside filter chamber in new wind; If just select when central air-conditioning system designs the filter that efficiency is very high, then resistance can be caused excessive, the phenomenon that operating cost is higher.Visible, traditional central air conditioning filtration system exists can not meet the shortcoming of haze weather to indoor accelerated test control overflow.
Chinese patent (publication number is CN101418973B) discloses a kind of air-conditioning box removing air molecule pollution thing, and it is in order to meet the filtering requirement of air Middle molecule pollutant, is provided with just medium effeciency filter, high efficiency particulate air filter and water smoke purging system.But itself and outside unresolved different chamber under meteorological operating mode, comfort air conditioning system system indoor accelerated test pollute control problem.
Chinese patent (publication number is CN102141276B) discloses a kind ofly has the initiatively air-conditioning box of antidusting function and the active antidusting method of air-conditioning box, it is formed primarily of non-woven fabrics belt, driving pump, dust blowing brush, surface cooler, electric heater, pressure fan, compression pump, conveyer, the mechanical, electrical magnetic field impulse valve of material level, pulse control instrument, casing, and what quasi-solution was determined is the air-conditioning box failure problems that under Sand Dust Environment, plugged filter causes.Visible, it is also under unresolved different outdoor weather operating mode, the control problem that comfort air conditioning system system indoor accelerated test pollutes.
Summary of the invention
The object of the invention is to: for above-mentioned Problems existing, provide one can control haze weather indoor environment Particulate Pollution, but do not increase air-conditioning box and the operation method thereof of operating mode air-conditioning system resistance at ordinary times.
The technical scheme of the technology of the present invention is achieved in that a kind of air-conditioning box controlling haze sky room air pollution, described air-conditioning box respectively with fresh wind tube, ajutage and backwind tube are communicated with, it is characterized in that: described fresh wind tube is communicated with the new wind fillter section in air-conditioning box by valve, described new wind fillter section is divided into separate upper new wind air channel and lower new wind air channel, the first new air-valve is disposed with along air supply direction described in new wind air channel, the at least new wind filter of two-stage, new wind blower fan and the second new air-valve, the new wind filter of described at least two-stage increases successively along air supply direction filter efficiency, the 3rd new air-valve is disposed with along air supply direction in described lower new wind air channel, first new wind filter and "four news" (new ideas air-valve.
The air-conditioning box of control haze sky of the present invention room air pollution, it is described in new wind air channel, be disposed with the second new wind filter and the 3rd new wind filter along air supply direction, and the filter efficiency of the described second new wind filter is less than the filter efficiency of the 3rd new wind filter.
The air-conditioning box of control haze sky of the present invention room air pollution, first new air-valve described in it and the second new air-valve are separately positioned on air inlet and the air outlet place in new wind air channel, described new wind air channel is communicated with the mixing section in air-conditioning box with fresh wind tube with the second new air-valve respectively by the first new air-valve, described 3rd new air-valve and "four news" (new ideas air-valve are separately positioned on air inlet and the air outlet place in lower new wind air channel, and described lower new wind air channel is communicated with the mixing section in air-conditioning box with fresh wind tube with "four news" (new ideas air-valve respectively by the 3rd new air-valve.
The air-conditioning box of control haze sky of the present invention room air pollution, backwind tube described in it is communicated with the mixing section in air-conditioning box, in described backwind tube, be provided with return air filter.
The air-conditioning box of control haze sky of the present invention room air pollution, it is divided into new wind fillter section, mixing section, main fillter section successively, shows cold bringing-up section, fan section and muffler section in described air-conditioning box, along air supply direction, and described ajutage is communicated with air-conditioning box by muffler section.
A kind of operation method of air-conditioning box of the control haze sky room air pollution as described in the claims, it is characterized in that: under operating mode at ordinary times, described 3rd new air-valve and "four news" (new ideas air-valve are opened, and the first new air-valve, new wind blower fan and the second new air-valve are closed, new wind is introduced by lower new wind air channel, after the first new wind filter filters, enter mixing section, and mix with the return air filtered through return air filter of being sent back to by backwind tube, then successively through main fillter section, show cold bringing-up section, after fan section and muffler section carry out cleanliness factor and heat and wet treatment, send into indoor through ajutage,
Under haze weather operating mode, described first new air-valve, new wind blower fan and the second new air-valve are opened, and the 3rd new air-valve and "four news" (new ideas air-valve are closed, new wind introduces upper new wind air channel by fresh wind tube, new wind sends into mixing section successively after the second new wind filter and the 3rd new wind filter filter, and mix with the return air filtered through return air filter of being sent back to by backwind tube, then successively through main fillter section, show after cold bringing-up section, fan section and muffler section carry out cleanliness factor and heat and wet treatment, to send into indoor through ajutage.
The present invention by arranging the new wind fillter section be made up of upper and lower new wind air channel in air-conditioning box, under operating mode at ordinary times, new wind enters mixing section by lower new wind air channel, and under haze weather operating mode, new wind then introduces upper new wind air channel by fresh wind tube, new wind sends into mixing section successively after the second new wind filter and the 3rd new wind filter filter, thus the control reached haze weather indoor environment Particulate Pollution, and do not increase operating mode air-conditioning system resistance at ordinary times, economical operation and control simple and convenient.
