TECHNICAL FIELD
The disclosure relates to the technical field of air conditioners, in particular to a sterilization air conditioner.
BACKGROUND ART
Air conditioners in China have entered hundreds of millions of families, bringing us warmth and coolness; but at the same time, the air conditioners have also caused pollution to us. According to surveys of air conditioning hygiene by China's Center for Disease Control and Prevention, only 6.12% of air conditioners are qualified at present, and almost half of remaining air conditioners are seriously polluting ones and almost the other half of them are heavily polluting ones.
According to operation principle of refrigeration of the air conditioners, dew is condensed at a surface air cooler of an indoor unit for a long time, which results in low temperature and humidity inside the surface air cooler of the indoor unit and a cabinet, which is very suitable for growth and reproduction of bacteria and viruses, especially for survival and reproduction of Corona Virus Disease 2019 virus, which can be breathed into lungs of persons and also can be blown to any corner of and any object in a house through an air-conditioning ventilation system. In addition, a primary filter is provided in front of the surface air cooler, air enters the surface air cooler through a filter screen, and dust in the air is gathered on the filter screen after long-term operation, and thus germs are more likely to survive and reproduce in the filter screen. Therefore, people who often stay in air-conditioned rooms often get sick. Harms may be caused to human functions such as a nervous system, a respiratory system and an immune system for people who stay in the air-conditioned rooms for a long time. Therefore, it is not an exaggeration that the air conditioners are gradually called a chronic killer at home and abroad.
Although an ultraviolet lamp tube can serve to sterilize, only parts that can be directly irradiated by ultraviolet rays can be sterilized and parts that can't be irradiated can't be sterilized because the ultraviolet rays can't diffract. Heating the surface air cooler to 56° C. for sterilization is only aimed at the surface air cooler itself, especially the air conditioner has an air inlet and an air outlet, which cannot be sealed. Therefore, not every part of the indoor unit of the air conditioner, especially the filter screen of the filter cannot be heated to a temperature of 56° C., and it is impossible to keep a time space for sterilization at 56° C. for 30 minutes. In addition, the temperature of 56° C. is only intended to kill a few bacteria and viruses, so above sterilization at 56° C. can't guarantee complete inactivation, which can't be called sterilization.
The sterilization refers to a measure that uses strong physical and chemical factors to make all microorganisms inside and outside any object lose their growth and reproduction ability forever. Commonly used sterilization methods include chemical reagent sterilization, ray sterilization, dry heat sterilization, moist heat sterilization and filtration sterilization. Thoroughness of sterilization is restricted by sterilization duration and strength of sterilization agent. Resistance of microorganisms to sterilant depends on original population density, or resistance of strains or given to the strains by an environment. Effect of the sterilization refers to physical or chemical methods to kill all microorganisms, including pathogenic and non-pathogenic microorganisms and spores, so that they can reach a sterility assurance level. After the sterilization, an uncontaminated item is called a sterile item. After the sterilization, an uncontaminated area is called a sterile area. The sterilization refers to killing or eliminating all microorganisms in a propagation medium, including pathogenic microorganisms and non-pathogenic microorganisms, and also including bacterial spores and fungal spores. Sterilization is a process to make products free of survived microorganisms, a goal of which is to kill or remove vegetative cells of all microorganisms and spores (or conidia) thereof in materials, so as to achieve a sterile process.
Dry heat sterilization. Burning sterilization or hot air sterilization in oven is called the dry heat sterilization.
Metal instruments or washed glassware can be completely sterilized (including bacterial spores) after being placed in an electric oven at 150 to 170° C. for 1 to 2 hours. Burning is the most thorough dry heat sterilization method, with its application scope being limited to sterilization of inoculating loops and needles or burning of materials with pathogenic bacteria and animal carcasses. This method is not suitable for sterilization for the air-conditioning system because of its high temperature.
Moist heat sterilization. Sterilization is made with boiling water, vapor or vapor pressurizing. Pasteurization is the moist heat sterilization, in which there are two low temperature holding method: (1) treatment at 61.7 to 62.8° C. for 30 minutes. (2) A modern high temperature short time method or treatment at 71.6° C. or slightly higher temperature for 15 minutes. Among above methods, the vapor pressurizing sterilization presents optimum effect, which can be made by vapor at a normal pressure or in a high-pressure vapor pot (generally at 1 kg/cm2), with a vapor temperature up to 121° C., which can kill all heat-resistant spores in 30 minutes. However, some substances that are easily destroyed by high pressure, such as some sugars or organic nitrogen compounds, and sterilization is optimally made at a pressure of 0.6 kg/cm2 at 110° C. for 15 to 30 minutes; at 135 to 145° C. for 3 to 5 hours; at 160° C. to 170° C. for 2 to 4 hours; 180 to 200° C. for 0.5 to 1 hour; and at above 200° C. for more than 0.5 hours. This method is not suitable for sterilization for the air-conditioning system because of its high temperature and the boiling water and the vapor.
Chemical reagent sterilization. Most chemical reagents have antibacterial effect at a low concentration and sterilization effect at a high concentration. 5% of carbolic acid, 70% of ethanol and ethylene glycol are commonly used. Chemical sterilants must be volatile in order to remove residual drugs on sterilized materials. Commonly used reagents for chemical sterilization include surface disinfectants, antimetabolites (sulfonamides, etc.), antibiotics and biopharmaceuticals. The antibiotics are a kind of secondary metabolites or artificial derivatives synthesized during life activities of microorganisms or other organisms, and they can inhibit life activities of or infect other organisms (including pathogens, viruses, cancer cells, etc.) at a very low concentrations, so that they can be used as excellent chemotherapeutic agents. The chemical reagent sterilization is more suitable for sterilization for the air-conditioning system because of its low temperature.
Bacteria blocking by filter. The filter screen is configured to block the bacteria, in which the bacteria cannot be inactivated. The bacteria is blocked on the filter screen for a long time, can't be inactivated and multiply on the filter screen, which is also very dangerous and harmful to people in the air-conditioned rooms. A virus has a smallest particle diameter, and common viruses have a diameter of 0.01 to 0.02 with a largest pox virus in animals having a diameter of 0.17 to 0.26 some large one having a diameter of 0.3 to 0.45 u m, and a foot and mouth disease virus having a diameter of 0.01 u m, which is the smallest virion in the world at present. For common influenza viruses, an influenza A HIN1 virus is 0.09 u m in diameter, an Ebola virus is 0.08 μm in diameter, a Sars virus is 0.06 to 0.22 u m in diameter and a Corona Virus Disease 2019 virus is 0.06 to 0.14 u m in diameter. Diameters of most bacteria range from 0.5 to 5 u m, with smallest bacteria of 0.2 μm in diameter. To sum up, a HEPA high-efficiency filter can only block bacteria of more than or equal to 0.3 u m instantly, and can't block bacteria of less than or equal to 0.3 u m, let alone viruses of 0.01 to 0.3 μm. To sum up, the HEPA high-efficiency filter can only be used to block the bacteria, but not viruses, which cannot be called sterilization.

FIG. 1 is a schematic diagram of a structural embodiment of a split wall-mounted sterilization air conditioner according to the present disclosure.
n FIG. 1, an air conditioning system terminal is an air conditioner indoor unit 1, which includes an air inlet 2 and an air outlet 3. A sterilization device 7 includes a disinfectant storage tank 8, disinfectant 9 and a disinfectant ejection port arrangement 10. The disinfectant ejection port arrangement 10 includes at least one ejection port. The device is very suitable for existing installed split air conditioners, as a sterilization system for household ventilation air conditioners. The disinfectant 9 can be disinfectants such as hydrogen peroxide, hydrogen peroxide silver ion, chlorine dioxide, etc., especially the hydrogen peroxide silver ion disinfectant has less smell and excellent sterilization effect, which, with a proper proportion, can serve to realize real-time sterilization operation in presence of people. Compared with other sterilization devices, this device has advantages of small investment, quick effect and thorough sterilization, and is a practical sterilization device for families and businesses. The sterilization device 7 can be configured in applications outside the air conditioner to adapt to use for sterilization of the existing installed split air conditioner, and can also be directly designed and configured inside the air conditioner by an air conditioner manufacturer at a factory so as to produce sterilization air conditioner products. The disinfectant ejection port arrangement 10 is arranged outside the air inlet 2 of the air conditioner, which facilitates sterilization operations of a filter screen 5 of a wall-hanging machine. The disinfectant ejection port arrangement 10 is arranged in the air inlet 2 of the air conditioner, which facilitates the factory to produce sterilization air conditioner products. In particular, it is arranged between the surface air cooler and the filter screen 5 of the wall-hanging machine, which facilitates better sterilization effect for the surface air cooler and the filter screen 5 of the wall-hanging machine in operation at the same time.
FIG. 2 is a schematic diagram of a structural embodiment of another split wall-mounted sterilization air conditioner according to the present disclosure.
In FIG. 2, an air conditioning system terminal can be an air conditioner indoor unit 1, which includes an air inlet 2 and an air outlet 3. The sterilization device 7 includes at least one group of ultrasonic disinfectant atomizing devices 11. Each of at least one group of ultrasonic disinfectant atomizing devices 11 includes a disinfectant storage tank 8, disinfectant 9, a disinfectant ejection port arrangement 10, an ultrasonic generator 12 and an ultrasonic electric control device 13. In operating, ultrasonic high-frequency electric pulse current generated by the ultrasonic electric control device 13 is transmitted to the ultrasonic generator 12, and a piezoelectric ceramic sheet in the ultrasonic generator 12 generates ultrasonic vibration, and the disinfectant is excited and atomized by the ultrasonic vibration until disinfectant particles overflow and are transported to the disinfectant ejection port arrangement 10 through a pipeline, sprayed to the air inlet 2 by the disinfectant ejection port arrangement 10, and sucked by an operating air conditioner. Firstly, bacteria and viruses in the filter screen are inactivated by the filter screen 5 of the indoor wall-hanging machine of the air conditioner. When wind containing the disinfectant particles passes the surface air cooler after passing through the filter screen 5 of the indoor machine of the air conditioner, bacteria and viruses remaining in the surface air cooler are inactivated, and at the same time, air containing the disinfectant particles serve to inactivate viruses and bacteria remaining in space and parts in an air conditioner cavity, and finally sterilized air containing the disinfectant is blown into a room from the air outlet 3 to sterilize the room. However, disinfectant mist entering the air conditioner from the air inlet 2 is not only used to sterilize the filter screen 5 of the indoor machine of the air conditioner and the surface air cooler behind the filter screen 5 of the indoor machine of the air conditioner, because disinfectant mist air entering the air conditioner from the air inlet 2 is pervasive and basically sterilizes all inner cavities of the air conditioner. In summer, sterilization operations are made with refrigeration of the air conditioner. In winter, sterilization is made combined with heating. In spring and autumn, the air conditioner is set in a ventilation operation mode, and room ventilation and sterilization operations can be carried out. If a primary filter of the filter screen 5 of the indoor machine of the air conditioner is changed to be a medium efficient or sub-high efficient filter, not only pm2.5 particles can be eliminated but also sterilization can be made, with functions far exceeding that of an air purifier, realizing all-in-one applications. The ultrasonic disinfectant atomizing device 11 or the disinfectant storage tank 8 is made of transparent materials, so that change in disinfectant level can be clearly seen, and the disinfectant can be added in time. In FIG. 2, there are two ultrasonic disinfectant atomizing devices 11 which are arranged flat and close to the blocking plates on two sides of the air conditioner, which function in balancing left and right and increasing disinfectant capacity, thus prolonging sterilization duration and reducing times of adding disinfectant. The disinfectant is atomized or sprayed in inlet air of the air conditioner, which is equivalent to a process of washing air entering the air conditioner with disinfectant liquid, and pm2.5 particles in the air falls into the disinfectant mist and is purified, which is actually equivalent to a process of washing and purifying the air with water. Therefore, the sterilization air conditioner not only realizes the sterilization operation of the air conditioner, but also obtains the function of an air purifier.
The disinfectant 9 not only includes hydrogen peroxide or hydrogen peroxide silver ion or chlorine dioxide or formaldehyde or glutaraldehyde or ethylene oxide or peracetic acid or chlorine or copper sulfate or ethanol or isopropanol or n-propanol disinfectant, but also can be changed to recognized brands and customary types according to standards for using disinfectants in different countries. The sterilization device according to this disclosure supports sterilization applications compatible with any kind of air disinfectants.
FIG. 3 is a schematic diagram of a structural embodiment of another split wall-mounted sterilization air conditioner according to the present disclosure.
In FIG. 3, other parts are exactly the same except that the ultrasonic generator 12 is arranged outside the disinfectant 9. The ultrasonic generator 12 is arranged outside the disinfectant 9, which facilitates atomization effect of the disinfectant to a certain degree, and other working principles are completely the same except the atomization effect is not influenced by a level or pressure of the disinfectant, and are not repeatedly described here again.
FIG. 4 is a schematic diagram of a structural embodiment of a split cabinet sterilization air conditioner according to the present disclosure.
In FIG. 4, an air conditioning system terminal includes an air conditioner indoor unit 1. The air conditioner indoor unit 1 includes an air outlet 3 and an air inlet 6 of an indoor cabinet of the air conditioner. The sterilization device 7 includes a disinfectant storage tank 8, disinfectant 9, a disinfectant pump 17, a nozzle connecting pipe 18 of the disinfectant pump and a nozzle 19. A disinfectant spray sterilization device is composed of a filter screen 20 of the indoor cabinet of the air conditioner. The nozzle 19 is arranged inside or outside the air inlet 6 of the indoor cabinet of the air conditioner. The disinfectant storage tank 8, the disinfectant 9 and the disinfectant pump 17 are arranged inside the cabinet. If the nozzle 19 is also arranged inside the air inlet 6 of the indoor cabinet of the air conditioner, it is convenient for manufacturers to manufacture sterilization air conditioner products.
