Description
VRSF-100-IL-21 AN INDOOR OZONE BASED AIR PURIFICATION SYSTEM AND METHOD Technical Field The present invention relates to air cleaning systems for purifying air. More particularly, to an indoor ozone-based air purification system and method for detecting and inactivating germs.
Background Ozone is a gas formed by molecules made up of 3 oxygen atoms (O3) and has the characteristic of being a powerful oxidizing agent. Thanks to this property it has proven to be highly effective in killing bacteria, fungi and inactivating viruses. Ozone can, therefore, be used for the treatment of potentially contaminated surfaces, water, and ambient air thanks to its powerful germicidal effect on a wide spectrum of microorganisms.
The effectiveness of ozone in treating microorganisms, especially bacteria and viruses, is related to various factors, i.e., ozone concentration, the temperature of the environment, humidity of the environment and exposure time.
Capsid surface proteins, as well as membrane receptors present on enveloped viruses, are the first targets of ozone because it reacts directly with amino acids and functional groups of proteins. This leads to various consequences both on the structure of the virus, which is compromised, and on its infectious capacity because the specific viral receptors used by the virus to bind to host cells and invade them are altered. Furthermore, ozone VRSF-100-IL-21 damages the membranes of the enveloped viruses through peroxidation of phospholipids and generating numerous Reactive Oxygen Species (ROS) capable of damaging also other viral macromolecules. In addition, ozone can inactivate viruses by causing damage to their genetic material, both DNA and RNA. The main mechanisms by which ozone acts on viruses, therefore, are due to the direct oxidation of various molecules and, indirectly, with the generation of ROS. Coronaviruses are classified as "enveloped viruses", which are typically more susceptible to "Physico-chemical challenges". In other words, ozone can neutralize coronaviruses. Ozone destroys this type of virus by breaking through the outer shell into the core, resulting in damage to the viral RNA. Ozone can also damage the outer shell of the virus in a process called oxidation.
While ozone is an excellent material for oxidizing germs, it is itself a highly toxic substance. The Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration level of more than 100 ppb (parts per billion) for more than 8 hours a day. For human beings, breathing ozone beyond the approved concentration can be harmful, and may cause symptoms such as coughing, shortness of breath, and aggravation of lung diseases like asthma. For that reason, many countries, today, have set a limit of 120-140 ppb (parts per billion) for ozone concentration levels.
Thus, while the use of ozone, as a material for oxidizing germs, is known to be effective, the hazardous nature of the ozone, for humans, has prevented it from widespread use. Some of the prior art publications have disclosed the use of ozone concentration detection modules in order to control the ozone concentration in the air. Nevertheless, even very expensive ozone concentration detection modules have been found to be inaccurate for VRSF-100-IL-21 measuring ozone at these very low levels. For these reasons, prior art purification systems are typically used for disinfecting an indoor room only when the room is evacuated from humans. Typically, once a space is vacated of humans, one of the prior art systems can be bought into the room and turned on while the room is closed. At this stage, the system can boost the ozone concentration in the room to much more than 100 ppb, effectively deactivating 99.99% of the viruses. After the disinfection, the system is turned off and the room is typically kept closed for at least a half an hour, in order to allow the ozone in the room to dissipate before anyone comes back into the room. Nevertheless, these prior art systems are not allowed to operate in the presence of humans for the reasons described above.
WO2016175473A1 discloses an Internet of Things-based (IOT) ozone sterilization air purification system for purifying air by increasing the amount of air to be purified by an air purifier. The disclosed object-based Internet air purification system includes a plurality of air purifiers arranged to be spaced apart from each other, where the disclosed object-based Internet ozone sterilizing air purification system comprises: An ozone generating unit for generating ozone by generating ozone in the air sucked into the air intake port; and an ozone generator installed inside the purifier body for discharging ozone generated in the ozone generator to the air outlet; an ozone discharge sensor for detecting the presence or absence of ozone in the air discharged to the air outlet; and an ozone sensor for detecting the presence or absence of ozone in the air discharged from the air outlet module. When an IOT module receives the ozone detection information, it can improve the air purifying capability by enabling a plurality of air purifiers to be linked to each other through the Internet of Things. Nevertheless, the disclosed system has limited use.
VRSF-100-IL-21 CN111692665 discloses an intelligent air purifier which comprises a control module, and an air purification module, an ozone concentration detection module and an ozone reduction module connected to the control module, wherein the ozone concentration detection module is arranged at a purification air outlet of the air purification module and is located between the air purification module and the ozone reduction module. As disclosed, the air purification module is used for purifying air. The ozone concentration detection module is used for detecting ozone concentration of ozone generated by operation of the air purification module, where the ozone reduction module is used for reducing ozone generated by operation of the air purification module when the detected ozone concentration is greater than an ozone concentration threshold value. The described control module is used for controlling opening and closing of the air purification module, the ozone concentration detection module and the ozone reduction module and is further used for sending the starting command to the ozone reduction module when the detected ozone concentration is greater than an ozone concentration threshold value. Nevertheless, the described intelligent air purifier can be inaccurate and therefore may be dangerous.
It would therefore be desired to propose a system void of these deficiencies.
Summary It is an object of the present invention to provide an indoor ozone-based sterilization air purification system capable of detecting and disinfecting a room from a wide spectrum of microorganisms.
VRSF-100-IL-21 It is another object of the present invention to provide an indoor ozonebased sterilization air purification system which can disinfect a room safely in the presence of humans.
It is still another object of the present invention to provide an indoor ozone-based sterilization air purification system which can detect a sudden change in the quantity of germs in the room and inactivate many of them.
It is still another object of the present invention to provide an indoor ozone-based sterilization air purification system which can be controlled and monitored both remotely and manually.
It is still another object of the present invention to provide an indoor ozone-based sterilization air purification system for detecting if a sick person has entered the room.
