Description

The VMC (Ventilation Mechanical Control System) of forest air-conditioning
Technical field
The present invention relates to material and energy field and field of Environment Protection, it is a kind of new method of indoor fresh air, can be severe Outdoor air or confined space, realize by rinse air removal indoor carbon dioxide, voc, formaldehyde, abnormal flavour, air-borne dust And the pollutant such as microorganism of dust attachment.
Background technology
The microclimate environment of current practicality -- air-conditioning technical has developed more than 80 year, due in modern architecture, idle call Electricity belongs to energy consumption rich and influential family, in energy-conservation, comfort level, dustless spatial development to very high level height, 18 DEG C of high temperature of Gree Chilled water system refrigerating efficiency cop reaches more than 8.5, in terms of energy-conservation, by electric expansion valve and motor frequency conversion, adjusts throttling system Excavation in the invention of cold-producing medium of number and different qualities and secondary latent heat, has reached more than 6.0 in refrigerating efficiency, in air 10000,1000,100,10 grades of clean room technology has been had on cleanliness factor；Thermal comfort is habitant to indoor thermal environment One important indicator of satisfaction, also has very big development.
China Business building construction amount is big at present, and the energy consumption more developed country of commercial building is high by 40% about, commercial building Energy-conservation is an extremely important, instant job.The air conditioning energy consumption of commercial building is the main portion of the energy consumption of commercial building Point, by formulation standard set up have stabiliser, have continued ability to innovate Chinese intelligent building technological innovation system, permissible Effectively reduce the air conditioning energy consumption of commercial building, and built commercial building air conditioner energy saving has, and the investment payback time is short, effect The high feature of benefit, is conducive to the development of commercial building air conditioner energy saving work.
Ashrae(U.S. heating, Refrigeration ＆ Air-Conditioning SE) standard due to its refrigeration, field of air conditioning authority Property, become the major technique reference of China Business building.The commercial building energy consumption more developed country of China is high by 40% about, wherein One of most important reason be current China central air-conditioning environment air quality not high, user is based on the ventilation cold draining that opens a window Want reason；User express comfortable satisfaction low this hiding the reason, cause the distrust to air conditioning system, such as " air-conditioning Disease " saying popular, idea mistake formed mistake using method.
Early in 20 beginnings of the century, people have begun to comfort research, air adjustment engineer, Study of Indoor Air Quality people Member etc. desirably can carry out quantitative forecast to human sense of comfort.
Comfort Evaluation has fanger thermal comfort equation theory and practice, and has multiple evaluation indexes: includes card tower cooler Ability, equivalent temperature, effective temperature, new effective temperature, standard effective temperature, consensus forecast reaction, comfortable equation and subjectivity temperature Degree etc., has the new technique high-efficiency appliance such as rotary dehumidifier developing into forth generation in humid control.According to existing design specification Various indoor air-conditioned environments are required to be intended to set fresh wind ratio, but under outdoor mal-condition, particularly in high concentration It is impossible to ensure that IAQ (indoor air quality) meets higher quality and requires, due to Chinese society not under harmful poisonous organic gas The disconnected gdp that pursues develops, and municipal pollution is serious, and air natural law up to standard in Chinese big city has descended to less than often circannian three points One of a kind of following, the little space of the life of high-cleanness, high, to ensureing that people are healthy extremely important.Present invention simultaneously relates to Material and energy field and field of Environment Protection.
In order to further understand to comfort level, as background technology, the technical requirements of air conditioner surroundings comfort level are entered below Row general introduction:
Based on the air-conditioner of Carnot cycle, rise in the sixties in last century, solve people indoors miniclimate to temperature index Requirement, especially to operation in patient, give highly useful help.
Thermal comfort is an important indicator to indoor thermal environment satisfaction for the habitant.Early in 20 beginnings of the century, people Begin to comfort research, air adjustment engineer, Study of Indoor Air Quality personnel etc. desirably can be relaxed to human body Suitable sense carries out quantitative forecast.
At present about air spray chamber, it is the demand setting for cold, belongs to big gas liquid ratio, and can be to be significantly increased The cost cooling of air humidity；Only use in easy factory floor, chicken farm low cost at present.Chilled water air spray chamber because This shortcoming of humid control difficult point, and water system produce the reason such as bacterial growth and fouling, and be not provided that comfortable temperature and To humidity effective control, existing market almost disappeares except research purposes.
Last century the mid-1960s, once had several terms to rise the cooling of water at low temperature rinse air, sent out in one factory of the U.S. Raw tens of people suffer from paragonimiasis westermani simultaneously, reason be longtime running cold water in rich aeriferous dust breed bacteria cause, Also report Korea S's somewhere winter life-time service ultrasonic humidifier within 2015, cause more than 20 paragonimiasis westermani patient's case.Water is Source of life, the sterilizing because of water cannot realize real-time online no dead angle under old technology, and microorganism leads to heat exchanger Fouling, serious paathogenic factor etc. are all that water uses the result of disabling with caution as transmission ＆ distribution medium.
By dry air and water vapour, dust, organic gas, haze, radioactive source etc. forms air, and harmful levels of pathogens is attachment It is present in the air in dust granules, radioactive source also can produce air pollution under the absorption of dust simultaneously；Dust proof workshop and The generally removal just for dust of sterile workshop room air cleanliness factor defines, and organic gas, harmful gass is not removed Index.
Existing air conditioning system is removed corresponding control technology to temperature humidity, and air quality is mainly using the method for ventilation Improve, the pollutant that wherein fresh-air ventilation removes have: carbon dioxide, tvoc(formaldehyde, abnormal flavour, organic gas).Belong to control at present Difficult point processed, fresh-air ventilation wastes a big chunk energy consumption.
Air-conditioning be using equipment and technology to the temperature of room air (or artificial mixed gas's body), humidity, air velocity and Cleannes are adjusted, and to environmental amenity requirement or produce the technological requirement to environment to meet people.Temperature, humidity are gentle Flow velocity degree is the requirement meeting the mankind to comfort, therefore claims comfort air conditioning；Cleannes are to comprise: dust, carbon dioxide, organic The index requests such as gas (tvoc), abnormal flavour.
Air-conditioning is an engineering technology, in modern architecture, is maximum energy consumption user, in the concept proposing energy saving building Under, the energy-conservation of air-conditioning, it is crucial, be most important link.China is populous nation, architectural energy consumption in urbanization process, mesh It is meant that energy consumption doubles, high energy consumption can bring more serious haze to the front codes and standards according to American-European countries.Current air-conditioning phase The specification closed and standard, all using outdoor air for pure air as premise, under haze weather, what is to be done for air-conditioning？Specification with Standard does not all provide answer.
In the requirement in " civil buildings heating ventilator and In Air Conditioning Design specification " (gb 50736-2012), design Minimum fresh air requirmente should meet following provisions:
Public building main room minimum fresh air requirmente needed for everyone should meet table 3.0.6-1 regulation.
Table 3.0.6-1 public building main room minimum fresh air requirmente needed for everyone [m3/(h people)]
Building room type resh air requirement
Office 30
Guest room 30
Hall, the four seasons Room 10
Most of air-conditioning technical personnel only understand that the purpose of air-conditioning is temperature, humidity and cleanliness factor, and little engineering technology can be exchanged The index of tolerance has deep essence understanding, can strict implement few；In haze sky, ignore ventilation and require.This ventilation volume Index is primarily directed to the ambiguous request that indoor carbon dioxide content's index is made.In Japan, there are legal provisions, airtight building In, positive mechanical ventilation wants run for 24 hours, and also there are relevant regulations in American-European countries, and World Health Organization who specifies the titanium dioxide of air-conditioning Carbon content have to be lower than 1200ppm, and American-European countries's respective value is 1000ppm, does not enforce standard, only in domestic specification Voluntary standard: indoor carbon dioxide sanitary standard gb/t 170942-1997≤1000ppm [1].This standard once forces to mark Quasi- execution, has 3-5 times of energy consumption increase.A lot of commercial mansions, school, large supermarket several times will increase energy consumption, and not having can Feasibility.
Central air-conditioning removing carbon dioxide content is difficult to control outer, an also individual insoluble difficult problem --- air conditioning disease, " air conditioning disease " It is in wet environment from vaporizer, easily nourishes antibacterial, especially after two-day weekend at weekend, Monday starts generation after air-conditioning Mycete abnormal smells from the patient, a lot of bacterial viruses grow, such as Legionnella, cause invisible killer.Ultraviolet light, ozone, coating catalyst Photocatalysis, activated carbon adsorption are all defective solutions: ultraviolet produces ozone and shading produces the weakness of blind area；If ozone Oxygen source is done with air, has strict Con trolling index, be difficult to control；Coating catalyst photocatalysis, also available energy accumulation decay, dust pollution The shortcomings of clean difficult afterwards；Activated carbon adsorption, true effect is very poor or completely ineffective, and can produce antibacterial secondary pollution.
Central air-conditioning also has a short slab, does not have removal ability to organic gas (voc), a lot of finishing materials and furniture have The slow release phenomenon of formaldehyde, meanwhile, in the place that the crowd is dense, the abnormal flavour that human body produces it is necessary to rely on fresh wind ventilation, other Method is extremely undesirable to air quality effect promoting.
Because haze weather is too many, the theory of air cleaning is rooted in the hearts of the people, and air purifier product is from the core skill adopting Art, to classify, is divided into two big class: filter net type and electrostatic two kinds of technology, wherein high level filter screen is generally termed hepa, also has Depurator is the combination of filter screen and electrostatic.Hepa needs blast high, produces noise and high energy consumption；Electrostatic precipitation can produce ozone, The secondary pollution problem such as powered dust, the toxicity of ozone is not high, but during producing ozone using air as oxygen source, can produce Strong carcinogen bromate, so be tightly controlled.Unite States Standard is 0.75ppm, and Chinese Industrial Standards (CIS) is 0.16mg/m3, just change ppm into It is 0.75pmm.
