Description
Technical Field
The utility model relates to an air purification disinfecting equipment technical field, in particular to integrated supporting degassing unit with air conditioner.
Background
An air conditioner generally includes one or more cold and heat source systems for performing cooling or heating and one or more air conditioning systems for performing cold air exchange or hot air exchange. Air conditioners have become popular in today's society. The central air conditioning system is particularly suitable for various hospitals, markets, enterprises, office buildings or suites, the air conditioning system in the central air conditioning system recycles indoor air, but the central air conditioning system is provided with a ventilation port, but the ventilation volume is usually limited to about 30%, and 70% of indoor air is still recycled. Therefore, the pollution degree of indoor air is 2-5 times more serious than that of outdoor air, more than 80% of people spend indoors on average, and the quality of the indoor air is the key of the health of people.
How to eliminate germs and infectious viruses in indoor air and purify the indoor air; particularly, in the operating room, ward and other areas of the hospital, the operating room needs to continuously maintain a sterile environment because of more patients and relatively dense personnel, thereby being convenient for operation and treatment. In the space, germs are easy to grow, and the indoor air is not easy to purify. In order to realize the disinfection of air droplet bacteria, viruses and the like in operating rooms and sickrooms of hospitals, the air droplet bacteria and viruses meet the general sanitation requirement of WS/T648-2019 air disinfectors. The existing disinfection modes comprise medicine fumigation, steaming, liquid medicine spraying, ultraviolet lamp irradiation, anion purification and the like, but all have certain limitations. The medicine fumigation, steaming and liquid medicine spraying are all operated manually and repeatedly, the operation is complicated, the medicine usage amount is large, the use cost is high, and dead corners exist easily; the ultraviolet lamp irradiation and the negative ion purification have wide application in the field of disinfection and purification. However, the existing anion purification equipment or ultraviolet disinfection equipment usually adopts independent equipment to realize disinfection or purification. The existing independent disinfection and purification equipment also integrates the ultraviolet light disinfection function and the anion purification function partially, but the disinfection function is realized by adopting ultraviolet light for disinfection, the ultraviolet light disinfection function is usually only used for disinfection of circulating air, the internal disinfection volume is limited due to the limitation of product space, the air circulation causes the air to stay in the disinfection cavity for a short time, the disinfection effect of the circulating air by the ultraviolet light is poor, certain high-standard requirements cannot be met, the power of the ultraviolet light is adjusted to be extremely high in time, the good disinfection and disinfection effect can not be achieved, and the relevant requirements of disinfection technical specifications (2002 edition) cannot be met.
Plasma purification and disinfection are commonly used in operating rooms or wards of hospitals, because the plasma purification and disinfection are combined into ozone by chemical reaction of O monatomic oxygen and O2 oxygen, which are separated from oxygen molecules in air by adopting electrons generated by high-voltage corona discharge, particularly doors and windows in areas such as wards and operating rooms are usually closed, plasma bodies are continuously operated and disinfected, and the ozone is difficult to decompose at normal temperature, so that the concentration of the indoor ozone is easy to exceed the standard; particularly, in an operating room, the plasma body disinfection technology is easy to cause the problem that particles flow to the abdominal cavity of a patient in operation, and large particle foreign matters or plasma body reactor electrode oxides are easy to fall into the abdominal cavity of the patient in operation along with airflow; due to foreign matters or poor contact of a high-voltage electrode, a large amount of high-amplitude sharp pulse waves are emitted by the plasma reactor to pollute the national power grid and operating room equipment, so that the electromagnetic compatibility (EMC) exceeds the standard; the plasma reactor is easy to detonate in flammable environments such as alcohol, gasoline and the like due to high-pressure ignition caused by foreign matters or poor contact of high-voltage electrodes, and has potential safety hazards.
Therefore, CN1310316A proposes a composite high-efficiency air purifier for central air conditioner, which uses a filter screen to filter for many times, and uses a negative ion generator to purify air, eliminate odor, and avoid air conditioning diseases. Although the air quality can be improved, the problems of poor air quality, multiplication of harmful bacteria and infectious viruses caused by a central air conditioner cannot be solved, and negative ions can only be gathered and settled, so that effective sterilization cannot be realized.
