In the ozone generation system, the air supply is directed to the centralized oxygen concentrator which then supplies a supply of concentrated oxygen to at least one ozone generators through at least one oxygen flow meter. The ozone generated from at least one ozone generator is distributed separately and simultaneously to each of the plurality of injection devices for forming ozone water. In the plurality of injection devices, the supply of generated ozone is mixed with a supply of water to form ozone water. The ozone water formed in the plurality of injection devices is then distributed to the plurality of rooms through a dedicated delivery piping system. An incoming water supply system is equipped to supply water to the plurality of injection devices to facilitate the mixing of water and ozone to form ozone water. A plurality of water outlets is connected to the plurality of injection devices which act as a trigger mechanism to initiate the forming of ozone water in the injection devices.

The number of dispensation means is configured based on the size of the room. A big room like a cinema will be allocated with a plurality of dispensation means while a small room like a study room will be allocated with at least one dispensation means.

In another embodiment, the distributed sterilizer control system controls the production of a supply of concentrated oxygen in the centralized oxygen concentrator adapted in the ozone generation system of a distributed sterilizer system. The air supply is directed to the centralized oxygen concentrator which then supplies a supply of concentrated oxygen to the plurality of ozone generators through a plurality of oxygen flow meters for generation of ozone. The ozone generated from the ozone generation system is distributed to the plurality of rooms through a series output tubing and a plurality of air dispensation means. A plurality of flow switches is equipped in the plurality of injection devices for detecting a flow of water in the injection devices. The ozone sterilization board controls and facilitates the operations of forming and distributing ozone water to any of the specific rooms. When a user opens a water outlet in any of the specific rooms, water starts to flow from the incoming water supply to the specific injection device. Upon detecting the flow of water in the injection device, the flow switch sends signals to the ozone sterilization control board to send signals to the ozone generation system to generate ozone. The specific ozone generator in the ozone generation system generates ozone using the supply of oxygen from the centralized oxygen concentrator. The ozone generated from the ozone generator is supplied to the specific injection device to initiate the mixing of the ozone with the flow of water in the injection device to form ozone water. The ozone water formed in the injection device is distributed to the specific room in which the water outlet is opened.

The distributed sterilizer control system controls the production and forming of ozone and ozone water to be distributed to a plurality of rooms based on a variety of applications. Depending on applications, a plurality of room is configured either to have only a supply of ozone, only a supply of ozone water or a combination of both supplies of ozone and ozone water.

The distributed sterilizer control system is adaptable into a distributed sterilizer system which operates either based on a demand-based configuration or a time-based configuration or a combination of both demand-based and time-based configurations, depending on different applications. In a dual configuration of time-based and demand-based of the distributed sterilizer system, the operation of both configurations is controlled by the ozone sterilization control board to be interchangeable in nature. The distributed sterilizer system is flexible in its dual configuration in which it can operate in a time-based configuration which is then replaced by a demand-based configuration and then revert to a time-based configuration.

In another embodiment, both generation and distribution of ozone to a plurality of rooms and forming and distribution of ozone water to a plurality of rooms is determined by dual configurations of time-based and demand-based as configured in the ozone sterilization control board. This embodiment accommodates of having two ozone generators whereby each ozone generator supplies ozone directly to the plurality of rooms through the air nozzles and into the plurality injection devices to initiate the mixing of the ozone with the flow of water in the injection devices to form ozone water before it is distributed to the specific rooms, respectively.

In the time-based configuration, the supply of ozone from the ozone generators to the plurality of rooms and injection devices respectively is determined based on a predetermined time-interval defined by two timers paired with two digital clocks in the ozone sterilization control system. The plurality of rooms may have different configurations of predetermined time-intervals for ozone to be distributed as defined by the pairs of timers and digital clocks.

In the demand-based configuration for distributing ozone to the plurality of rooms, the time-based configuration is replaced by a demand-based configuration once the concentration level of ozone in any of the rooms is detected to be above or below the predetermined maximum and minimum concentration level of ozone, respectively. Upon detecting the concentration level of ozone in any of the plurality of rooms is above a predetermined maximum level by a plurality of ozone sensors, the specific ozone sensor sends signals to the ozone sterilization control board to switch OFF the first ozone generator to stop the generation and distribution of ozone to the room. Simultaneously, an alert is triggered by visually and audibly reflecting the alert with the LED lights and buzzer on the ozone sterilization control board and simultaneously communicate this alert to the external communication module to prompt the user. The ozone sterilization control board is configured with a delay timer function capability in which the dedicated ozone generator is only turned OFF if the collected readings of the concentration level of ozone is maintained for a predetermined period of time. The delay timer function seeks to prevent the ozone generator from switching ON and OFF rapidly due to the potential fluctuation of concentration level of ozone as detected by the plurality of ozone sensors. Upon detecting that the concentration level of ozone in any of the plurality of rooms is below a predetermined minimum level by the plurality of ozone sensors, the specific ozone sensor sends signals to the ozone sterilization control board to switch ON the ozone generator to produce ozone to be delivered to the specific room. Simultaneously, an alert is triggered by visually and/or audibly reflecting the alert with the LED lights and/or buzzer on the ozone sterilization control board and simultaneously communicate this alert to the external communication module to prompt the user. A delay timer function capability in the ozone sterilization control board is similarly used to ensure that the collected readings of the concentration level of ozone is maintained for a predetermined period of time before the signal is sent to switch ON the ozone generator. The predetermined maximum and minimum concentration level of ozone is configured and controlled by the ozone sterilization control board.

In the demand-based configuration for distributing ozone water to the plurality of rooms, the time-based configuration is replaced by a demand-based configuration upon detecting a demand for ozone water by the user in any of the plurality of rooms. Each of the injections devices is equipped with a flow switch. When a user opens a water outlet in any of the specific rooms, water from the incoming water supply starts to flow into the specific injection device. Upon detecting the flow of water above the predetermined minimum amount of water in the injection device, the flow switch sends signals to the ozone sterilization control board to send signals to the second ozone generator to generate ozone. The time-based configuration is then replaced with a demand-based configuration by the ozone sterilization control board. The ozone generated from the second ozone generator is supplied to the specific injection device to initiate the mixing of the ozone with the flow of water in the injection device to form ozone water. The ozone water formed in the injection device is distributed to the specific room in which the water outlet is opened. The predetermined minimum amount of water in the injection devices is configured and controlled by the ozone sterilization control board.

In another embodiment, both generation and distribution of ozone to a plurality of rooms and forming and distributing ozone water to a plurality of rooms operates based on dual configurations which are time-based and demand-based as configured in the ozone sterilization control board. This embodiment is essentially identical to the earlier embodiment with the exception of having one ozone generator and two pinch valves. Instead of providing two dedicated ozone generators like in the earlier embodiment, this embodiment has one shared ozone generator to provide a supply of ozone water to a plurality of rooms is determined by dual configurations of time-based ozone and two pinch valves with each pinch valve to distribute the ozone generated from the shared ozone generator directly to a plurality of rooms through the air nozzles and to a plurality of injection devices to form ozone water to be distributed to the plurality of rooms, respectively. The operation of the pinch valves is controlled by the ozone sterilization control board to distribute the ozone generated from the shared ozone generator.

In the time-based configuration, the operation of switching ON and OFF for the two pinch valves to distribute ozone from the first ozone generator is determined by a predetermined time-interval defined by two timers paired with two digital clocks in the ozone sterilization control system. Each pair of timer and digital clock defines a predetermined timeinterval for each pinch valve. The plurality of rooms has different configuration of predetermined time-intervals for ozone to be distributed as defined by the plurality of timers and digital clocks.

In the demand-based configuration for controlling the operation of the first and second pinch valves by switching ON and OFF is replaced by a demand-based configuration upon detecting the concentration level of ozone in any of the rooms detected to be above or below the predetermined maximum and minimum concentration level of ozone, respectively and upon detecting the flow of water above the predetermined minimum amount of water in the injection devices. Upon detecting the ozone concentration level in a plurality of rooms to be above or below the predetermined maximum and minimum concentration level of ozone as configured by the ozone sterilization board, the ozone sensors send signals to the ozone sterilization control board to either switch OFF or ON the first pinch valve to either stop or initiate the generation and distribution of ozone to the room. Simultaneously, an alert is triggered to be visually and/or audibly reflected by the LED lights and/or buzzer on the ozone sterilization control board and an alert is simultaneously communicated to the external communication module to prompt the user. A delay timer function capability in the ozone sterilization control board is used to ensure that the collected readings of the concentration level of ozone is maintained for a predetermined period before the signal is sent to switch OFF or ON the first pinch valve and before the signals are sent to trigger the display LED lights and buzzer. Upon detecting the presence of water in the injection devices, a signal is sent to the ozone sterilization board to supply ozone from the shared ozone generator to supply ozone to the injection devices by switching ON the second pinch valve. The ozone water formed in the injection device is distributed to the specific room in which the water outlet is opened. The predetermined minimum amount of water in the injection devices is configured and controlled by the ozone sterilization control board.

In another embodiment, the distributed control system is adapted into a distributed sterilizer system which has two ozone generators and two pinch valves for generating and distributing ozone into the plurality of rooms and forming ozone water to be distributed into the plurality of rooms based on dual configurations of time-based and demand-based configured in the ozone sterilization control board.

The second ozone generator forms and distribute a supply of ozone directly to the plurality of rooms.

In the time-based configuration, the operation of switching ON and OFF for the two pinch valves to distribute ozone from the first ozone generator is determined by a predetermined time-interval defined by two timers paired with two digital clocks in the ozone sterilization control system. Each pair of timer and digital clock defines a predetermined timeinterval for each pinch valve. The plurality of rooms has different configuration of predetermined time-intervals for ozone to be distributed through the two pinch valves as defined by the plurality of timers and digital clocks.

In the demand-based configuration for controlling the operation of the first and second pinch valves by switching ON and OFF is replaced by a demand-based configuration upon detecting the concentration level of ozone in any of the rooms detected to be above or below the predetermined maximum and minimum concentration level of ozone, respectively and upon detecting the flow of water above the predetermined minimum amount of water in the injection devices. Upon detecting the ozone concentration level in a plurality of room to be above or below the predetermined maximum and minimum concentration level of ozone as configured by the ozone sterilization board, the ozone sensors send signals to the ozone sterilization control board to either switch OFF or ON the first pinch valve to either stop or start the generation and distribution of ozone to the room. Simultaneously, an alert is triggered to be visually and/or audibly reflected by the LED lights and/or buzzer on the ozone sterilization control board and an alert is simultaneously communicated to the external communication module to prompt the user. A delay timer function capability in the ozone sterilization control board is used to ensure that the collected readings of the concentration level of ozone is maintained for a predetermined period before the signal is sent to switch OFF or ON the first pinch valve and before the signal is sent to trigger the display LED lights and buzzer. Upon detecting the presence of water in the injection devices, a signal is sent to the ozone sterilization board to supply ozone from the shared ozone generator to supply ozone to the injection devices by switching ON the second pinch valve. The ozone water formed in the injection device is distributed to the specific room in which the water outlet is opened. The predetermined minimum amount of water in the injection devices is configured and controlled by the ozone sterilization control board.

In the time-based configuration for distributing ozone to the plurality of rooms, the supply of ozone from the second ozone generator to the plurality of rooms is determined based on a predetermined time-interval defined by a second pair of a timer and a digital clock in the ozone sterilization control board. The plurality of rooms may have different configuration of predetermined time-intervals for ozone water to be distributed as defined by the pair of timer and digital clock.

In the demand-based configuration for distributing ozone to the plurality of rooms, the time-based configuration is replaced with a demand-based configuration upon detecting the concentration level of ozone in any of the plurality of rooms is above a predetermined maximum level by a plurality of ozone sensors, The specific ozone sensor sends signals to the ozone sterilization control board to switch OFF the second ozone generator to stop the generation and distribution of ozone to the room. Simultaneously, an alert is triggered by visually and/or audibly reflecting the alert with the LED lights and/or buzzer on the ozone sterilization control board and simultaneously communicate this alert to the external communication module to prompt the user. The ozone sterilization control board is configured with a delay timer function capability in which the second ozone generator is only turned OFF if the collected readings of the concentration level of ozone is maintained for a predetermined period of time. The delay timer function seeks to prevent the second ozone generator from switching ON and OFF rapidly due to the potential fluctuation of concentration level of ozone as detected by the plurality of ozone sensors. Upon detecting that the concentration level of ozone in any of the plurality of rooms is below a predetermined minimum level by the plurality of ozone sensors, the specific ozone sensor sends signals to the ozone sterilization control board to switch ON the second ozone generator to generate and distribute ozone to the room. Simultaneous, an alert is trigged to be visually and/or audibly reflected by the display LED lights and/or buzzer on the ozone sterilization control board and simultaneously sends an alert to the external communication module to prompt the user. A delay timer function capability in the ozone sterilization control board is similarly used to ensure that the collected readings of the concentration level of ozone is maintained for a predetermined period before the signal is sent to switch OFF or ON the second ozone generator and before the signal is sent to trigger the display LED lights and/or buzzer. The predetermined maximum and minimum concentration level of ozone is configured and controlled by the ozone sterilization control board.

When a user opens a water outlet in any of the specific rooms, water from the incoming water supply starts to flow to the specific injection device equipped with a flow switch. Upon detecting the flow of water in the injection device, the flow switch sends signals to the ozone sterilization control board to send signals to the specific ozone generator to generate ozone.

When a user opens the water outlet in any of the specific rooms, water from the incoming water supply starts to flow into the specific injection device. The available supply of the ozone generated from the shared ozone generator is mixed with the flow of water in the injection device to form ozone water. In the event that the water outlet is closed and no water flows into the injection device, the unused ozone generated from the shared ozone generator is channeled to the plurality of rooms through an output tubing.

The proprietary interface board DC functions as a connector between the ozone sterilization control board CB and the external communication module EM. The proprietary interface board DC has a set of definable register map that communicates with the ozone sterilization control board CB and the external communication module EM. The register map has pre-set configurations to cater to the different scenarios/parameters in the distributed sterilizer system 100. The proprietary interface board DC provides a set of complex features and functions to control, monitor and manage the performance of any distributed sterilizer system 100 via web based applications. The proprietary interface board DC provides an integrated processing capability for processing the collected data in the distributed sterilizer control system CS. The proprietary interface board DC is connected to the external communication module EM either through a secure remote access network i.e. wide area network gateway or a Wi-Fi access point. The external communication module EM comprises of a cloud server WS which is directly accessible by any mobile devices or computers through either a Wi-Fi network or a cellular network which have the relevant web-based app installed accordingly. The principle or users are able to access the cloud server WS which is connected to the proprietary interface board DC and ozone sterilization control board CB to monitor, control and distribute ozone water and ozone in the distributed sterilizer system 100. In the distributed sterilizer control system CS, the ozone sterilization control board CS is the main component which controls the operations of the distributed sterilizer system 100. The ozone sterilization control board CS comprises of a digital display 16a which displays visual information and allowing users to monitor and control the parameters in the distributed sterilizer system 100, an LED display 16b and a buzzer 16c whereby both function as warning alert tools to prompt the user of any possible malfunction of the components within the distributed sterilizer system 100, a plurality of timers 12 and a plurality of digital clocks C. Each timer 12 is paired with a digital clock C.

The distributed sterilizer system 100 has an ozone generation system 1 , a plurality of injection devices 2a, 2b, 2c, 2d, 2e, 2f, a plurality of flow switches 3a, 3b, 3c, 3d, 3e, 3f, a plurality of water outlets 9a, 9b, 9c, 9d, 9e, 9f and a delivery piping systems 8, 10 to generate, form and distribute ozone and ozone water to three pluralities of rooms R1 , R2, R3, R5, R6, R7, R9, R10, R1 1 . The first plurality of rooms R5, R6, R7 are sections which ozone is directly distributed from the ozone generation system 1. The second plurality of rooms R1 , R2, R3 are different sections in which ozone water is formed and distributed from the ozone generation system 1. The third plurality of rooms R9, R10, R1 1 are different sections which both ozone and ozone water is distributed from the ozone generation system 1 . The ozone generation system 1 comprises a centralized oxygen concentrator 4, two oxygen flow meters 5a, 5b and two ozone generators 6a, 6b. The outdoor air is directed to the ozone generation system 1 in which it is first directed to the centralized oxygen concentrator 4. In the centralized oxygen concentrator 4, the supply of outdoor air containing 21% of oxygen combined with nitrogen and a mixture of other gases. The air supply is then pressurized and compressed in the centralized oxygen concentrator 4 to yield oxygen with a pressure in the range of 0.04 MPa to 0.06 MPa. The examples of the different ranges of the oxygen purity /concentration generated from the centralized oxygen concentrator 4 are as follows: 55%@3LPM, 70%@2LPM and 90%@1 LPM. The first ozone generator 6a forms ozone to be distributed directly to the first plurality of rooms R5, R6, R7 through a series of outputting tubing 10 and air nozzles 1 1 a, 1 1 b, 1 1 c. The second ozone generator 6b forms ozone to be supplied to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with a flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water formed in the injection devices 2a, 2b, 2c is distributed to the water outlets 9a, 9b, 9c of the second plurality of rooms R1 , R2, R3 through the delivery piping system 8. The first ozone generator 6a also forms ozone to be distributed directly to the third plurality of rooms R9, R10, R1 1 through a series of outputting tubing 10 and air nozzles 1 1 d, 11 e, 1 1f. The second ozone generator 6b also forms ozone to be distributed to injection devices 2d, 2e, 2f to initiate the mixing of the ozone with a flow of water in the injection devices 2d, 2e, 2f to form ozone water. The ozone water formed in the injection devices 2d, 2e, 2f is distributed to the water out lets 9d, 9e, 9f of the third plurality of rooms R9, R10, R1 1.

An air flow meter 17 and an oxygen sensor 18 is provided to monitor the flow of the air supply or outdoor air to the centralized oxygen generator 4 and the flow and concentration of oxygen supplied from the centralized oxygen generator 4 to the ozone generators 6a, 6b. If there is a problem of a decreased flow of air supply to the centralized oxygen generator 4 or decrease in the flow and concentration of the supply of oyygen from the centralized oxygen generator 4 detected by the air flow meter 17 and oxygen sensor 18, an alert of the malfunction is trigged by visually and/or audibly displayed on the ozone sterilization control board CB. The alert is reflected by the LED display 16b and/or a buzzer 16c on the ozone sterilization control board CB whereby both function as warning alert tools to prompt the user of the malfunction.

Each nozzle 11 a, 1 1 b, 1 1c, 1 1 d, 11 e, 11 f is manually adjustable by turning each knob to release the required ozone into the first and third pluralities of rooms R5, R6, R7, R9, R10, R1 1 based on a desired flow rate, Ipm depending on the indoor volume of the rooms for sterilization. The ozone sterilization control board CB is also able to digitally control the air flow of each individual nozzles 1 1 a, 1 1 b, 1 1 c, 1 1 d, 1 1 e, 1 1 f via remote access either through Bluetooth, RF or Wi-Fi network. The amount of flow rate of ozone to be delivered to the rooms R5, R6, R7, R9, R10, R11 through the nozzles 11 a, 1 1 b, 1 1 c, 11 d, 1 1 e, 1 1 f is configured and defined by the ozone sterilization control board CB.

Both generation and distribution of ozone to the first plurality of rooms R5, R6, R7 and forming and distribution of ozone water to the second plurality of rooms R1 , R2, R3 and both ozone and ozone water to the third plurality of rooms R9, R10, R1 1 is determined based on dual configurations which are time-based and demand-based. The operations of the components as controlled by the distributed ozone control system CS to be interchangeable between the time-based and demand-based configurations.

Four timers 12a, 12b, 12c, 12d paired with four digital clocks 01 , C2, C3, C4 respectively are adapted in the ozone sterilization control board CB. Each of the two timers 12a, 12b and the digital clocks C1 , C2 selectively operates the two ozone generators 6a, 6b between ON and OFF states by defining the duration of the time intervals for the ON and OFF states. A timer 12c paired with a digital clock C3 selectively operates both the ozone generators 6a, 6b between ON and OFF states by defining the duration of the time intervals for the ON and OFF states. A timer 12d paired with a digital clock 04 selectively operates the centralized oxygen generator 4.

The centralized oxygen generator 4 is pre-programmed by the ozone sterilization control board CB to be turned ON to generate ozone in the event either one of the two ozone generators 6a, 6b is turned ON.

In the time-based configuration, according to the predetermined time intervals, the ozone generators 6a, 6b generate and supply ozone directly to the first plurality of rooms R5, R6, R7, supply ozone directly to the plurality of injection devices 2a, 2b, 2c, 2d, 2e, 2f to form ozone water to be distributed to the second plurality of rooms R1 , R2, R3 and supply both ozone and ozone water to the third plurality of rooms R9, R10, R1 1. The duration of the predetermined time intervals as defined by the plurality of timers, 12a, 12b, 12c and digital clocks 01 , 02, 03 is configured by the user at the ozone sterilization control board CB. For example, in this embodiment, the predetermined interval times are configured to be 15, 30, 35 minutes defined by the timers 12a, 12b, 12c and digital clocks 01 , 02, 03 for both ozone generators 6a, 6b.

The first ozone generator 6a is switched OFF by the first timer 12a and digital clock 01 for an interval time of 10 minutes. After the interval 10 minutes ends, the first ozone generator 6a is switched ON again for the next 20 minutes before it is switched OFF again. During the interval time of 20 minutes in which the first ozone generator 6a is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to centralized oxygen generator 4 to supply oxygen to the first ozone generator 6a through an oxygen flow meter 5a to generate ozone. The first ozone generator 6a generates a supply of ozone to be distributed directly to the first plurality of rooms R5, R6, R7 through a series of output tubing 10 and air nozzles 11 a, 1 1 b, 1 1 c.

The second ozone generator 6b is switched OFF by the second timer 12b and digital clock C2 for an interval time of 30 minutes. After the interval 30 minutes ends, the second generator 6b is switched ON again for the next 30 minutes before it is switched OFF again. During the interval time of 30 minutes in which the second ozone generator 6b is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to the centralized oxygen generator 4 to supply oxygen to the second ozone generator 6b through an oxygen flow meter 5b to generate ozone. The second ozone generator 6b generates a supply of ozone to be distributed to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with a flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water formed in the injection devices 2a, 2b, 2c is distributed to water outlets 9a, 9b, 9c of the second plurality of rooms R1 , R2, R3 through the delivery piping system 8.

The first ozone generator 6a and second ozone generator 6b are switched OFF by the third timer 12c and digital clock C3 for an interval time of 35 minutes. After the interval 35 minutes ends, the first and second ozone generators 6a, 6b are switched ON again for the next 35 minutes before it is switched OFF again. During the interval time of 30 minutes in which the first and second generators 6a, 6b is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to supply oxygen to the first and second ozone generators 6a, 6b through two oxygen flow meters 5a, 5b to generate ozone. The first ozone generator 6a generates a supply of ozone to be directly distributed to the third plurality of rooms R9, R10, R1 1. Simultaneously, the second ozone generator 6b generates a supply of ozone to be distributed to the injection devices 2d, 2e, 2f to initiate the mixing of the ozone with a flow of water in the injection devices 2d, 2e, 2f to form ozone water. The ozone water formed in the injection devices 2d, 2e, 2f is distributed to the rooms R9, R10, R1 1 through the delivery piping system 8. The operation of the first ozone generator 6a and second ozone generator 6b to distribute the ozone and ozone water to the third plurality of rooms R9, R10, R1 1 can be configured by the ozone sterilization board CB to have two different predetermined intervals. For example, in this embodiment, the predetermined interval times for the first and second ozone generators 6a, 6b to distribute ozone or ozone water to the third plurality of rooms R9, R10, R1 1 as defined by the timer 12c and digital clock C3 are 10 and 30 minutes respectively.

In the demand-based configuration for producing and distributing ozone, the timebased configuration is replaced by a demand-based configuration once the concentration level of ozone in any of the first and third pluralities of rooms R5, R6, R7, R9, R10, R1 1 is detected to be above or below the predetermined maximum and minimum concentration level of ozone, respectively. In a demand-based configuration, upon detecting the concentration level of ozone in any of the first and third pluralities of rooms R5, R6, R7, R9, R10, R1 1 is above a predetermined maximum concentration level by three dedicated ozone sensors 01 , 02, 03, 04, 05, 06 the specific ozone sensor 01 , 02, 03, 04, 05, 06 sends signals to the ozone sterilization control board CB to switch OFF the first ozone generator 6a to stop the supply of ozone from the first ozone generator 6a to the rooms R5, R6, R7, R9, R10, R1 1. Simultaneously, an alert is triggered by visually and/or audibly reflecting the alert with the LED lights 16b and/or buzzer 16c on the ozone sterilization control board CB and simultaneously communicate this alert to the external communication module EM to alert the user. The ozone sterilization control board CB is further configured with a delay timer function capability in which the first ozone generator 6a is only turned OFF if the collected readings of the concentration level of ozone is maintained for a predetermined period. The delay timer function seeks to prevent the first ozone generator 6a from switching ON and OFF rapidly due to the potential fluctuation of concentration level of ozone as detected by the ozone sensors 01 , 02, 03, 04, 05, 06. Upon detecting that the concentration level of ozone in any of the first plurality of rooms R5, R6, R7 is below a predetermined minimum concentration level by the ozone sensors 01 , 02, 03, 04, 05, 06 the specific ozone sensor 01 , 02, 03, 04, 05, 06 sends signals to the ozone sterilization control board CB to switch ON the first ozone generator 6a or the second generator 6b to start and distribute the supply of ozone from the first ozone generator 6a or the second generator 6b into any of the rooms R5, R6, R7, R9 , R10, R11. Simultaneously, an alert is triggered which is visually and/or audibly displayed by the LED lights 16b and/or buzzer 16c in the ozone sterilization control board CB and simultaneously sends an alert to the external communication module ECM to alert the user. The adjustment of the level of ozone in first and third pluralities of rooms R5, R6, R7, R9, R10, R1 1 can be done either with manual adjustment of the nozzles 11 a, 1 1 b, 1 1c, 1 1 d, 1 1 e, 1 1 f by turning the knob of the nozzles 11 a, 11 b, 1 1c, 1 1 d, 1 1 e, 1 1 f or with digital control of the air flow of the nozzles 1 1 a, 1 1 b, 1 1c, 1 1 d, 1 1 e, 11 f by the ozone sterilization control board CB via remote access through Bluetooth, RF or Wi-Fi network. A delay timer function capability in the ozone sterilization control board CB is similarly used to ensure that the collected readings of the concentration level of ozone is maintained for a predetermined period before any signal is sent to switch ON the first ozone generator 6a and before a signal is sent to trigger an alert to be visually and/or audibly reflected by the display LED lights 16b and/or buzzer 16c. The range of predetermined maximum concentration level of ozone in the first and third pluralities of rooms R5, R6, R7, R9, R10, R1 1 is configured to be between 0.05 and 0.06 ppm and the range predetermined minimum concentration level of ozone in the first and third pluralities of rooms R5, R6, R7, R9, R10, R1 1 is configured to be between 0.04 and 0.45 ppm. For the delay timer mechanism in the ozone sterilization control board CB, it can be configured by the ozone sterilization control board CB for the readings to be maintained anywhere between 10 to 15 seconds before an alert is triggered by the ozone sterilization control board CB.

In a demand-based configuration for producing ozone to form ozone water, the timebased configuration is replaced by a demand-based configuration once there is a demand of water detected in any of the second and third pluralities of rooms R1 , R2, R3, R9, 10, R11. Each of the injection devices 2a, 2b, 2c, 2d, 2e, 2f is equipped with flow switches 3a, 3b, 3c, 3d, 3e, 3f. The injection devices 2a, 2b, 2c is equipped with flow switches 3a, 3b, 3c to control and distribute the production of ozone water into the second plurality of rooms R1 , R2, R3. The injection devices 2d, 2e, 2f is equipped with flow switches 3d, 3e, 3f to control and distribute the production of ozone water into the third plurality of rooms R9, R10, R1 1 . When a user opens a water outlet 9a, 9b, 9c, 9d, 9e, 9f in any of the specific room R1 , R2, R3, R9, 10, R1 1 , water from the incoming water supply starts to flow into the specific injection device 2a, 2b, 2c, 2d, 2e, 2f. Upon detecting the flow of water above the predetermined minimum amount of water in the injection device 2a, 2b 2c, 2d, 2e, 2f, the flow switch 3a, 3b, 3c, 3d, 3e, 3f sends signals to the ozone sterilization control board CB to supply oxygen to the centralized oxygen generator 4 for supplying oxygen to the second ozone generator 6b to generate ozone. The ozone generated from the second ozone generator 6b is supplied to the specific injection device 2a, 2b, 2c, 2d, 2e, 2f to initiate the mixing of the ozone with the flow of water in the injection device 2a, 2b, 2c, 2d, 2e, 2f to form ozone water. The ozone water formed in the injection device 2a, 2b 2c, 2d, 2e, 2f is distributed to the water outlets 9a, 9b, 9c, 9d, 9e, 9f of the rooms R1 , R2, R3, R9, R10, R1 1 through the delivery piping system 8 in which the water outlet 9a, 9b, 9c, 9d, 9e, 9f is opened. The predetermined minimum amount of water detected in the injection devices 2a, 2b, 2c, 2d, 2e, 2f detected is configured and controlled by the ozone sterilization control board CB. The range of predetermined minimum amount of water detected by the flow switches 3a, 3b, 3c, 3d, 3e, 3f in the injection devices 2a, 2b, 2c is configured to be between 6 Ipm and 8 Ipm.

Figure 2 is a block diagram which illustrates a distributed sterilizer control system CS which is adapted into a second embodiment of a distributed sterilizer system 200 which comprises all the components of the first embodiment with the modification of using one shared ozone generator 6a1 instead of two ozone generators and two additional pinch valves PV1 , PV2 for distributing ozone from a shared ozone generator 6a1 . The manner of how all of the components are monitored and controlled to generate, form and distribute ozone and ozone water to the first and second pluralities of rooms, R5, R6, R7, R1 , R2, R3 in this second embodiment of a distributed sterilizer system 200 is essentially similar to the first embodiment of the distributed sterilizer system 100. In this embodiment, the ozone generated from the shared ozone generator 6a1 is supplied to two pinch valves PV1 , PV2 which is then distributed to the first and second pluralities of rooms R5, R6, R7, R1 , R2, R3 which requires ozone and ozone water, respectively. The ozone supplied to the first pinch valve PV1 is to be directly distributed to the first plurality of rooms R5, R6, R7 through a series of output tubing 10 and air nozzles 1 1 a, 1 1 b, 1 1c. The ozone supplied to the second pinch valve PV2 is to be distributed to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with the flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water formed in the injection devices 2a, 2b 2c is distributed to the second plurality of rooms R1 , R2, R3 through the delivery piping system 8. The centralized oxygen generator 4 is pre-programmed by the ozone sterilization control board CB to be turned on to generate ozone in the event any one of the first and second pinch valves PV1 , PV2 is turned on. In this embodiment, the distributed sterilizer control system CS similarly accommodates the capability of operating in dual configurations of time-based and demandbased controlled by the ozone sterilization control board CB. The operation of the two pinch valves PV1 , PV2 is controlled by the ozone sterilization control board CB to operate in both time-based and demand-based configurations interchangeably.

In the time-based configuration, the timing of switching ON and OFF of the first and second pinch valves PV1 , PV2 is controlled by the two timers, 12a, 12b paired with two digital clocks C1 , C2 respectively in the ozone sterilization control board CB. Each of the two timers 12a, 12b and the digital clocks C1 , C2 selectively operates the first and second pinch valves PV1 , PV2 respectively between ON and OFF states by defining the duration of the time intervals for the ON and OFF states. The centralized oxygen generator 4 is pre-programmed by the ozone sterilization control board CB to be turned ON to generate ozone in the event either one of the first and second pinch valves PV1 , PV2 is turned ON. According to the predetermined time interval, the two pinch valves PV1 , PV2 supply ozone directly to the first rooms R5, R6, R7 and supply ozone directly to the plurality of injection devices 2a, 2b, 2c to form ozone water for distribution to the second plurality of rooms R1 , R2, R3. The duration of the predetermined time intervals is configured by the user at the ozone sterilization control board CB. For example, in this embodiment, the predetermined interval time is 15 and 30 minutes for the first and second pinch valves PV1 , PV2 respectively. The first pinch valve PV1 is switched OFF by the first timer 12a and a digital clock C1 for an interval time of 15 minutes. After the interval 15 minutes ends, the first pinch valve PV1 is switched ON again for the next 15 minutes before it is switched OFF again. During the interval time of 15 minutes in which the first pinch valve is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to the centralized oxygen generator 4 to supply oxygen to the shared ozone generator 6a1 through the oxygen flow meter 5 to generate ozone. The ozone generated from the shared ozone generator 6a1 is supplied to the first pinch valve PV1 to be distributed directly to the first plurality of rooms R5, R6, R7 through a series of output tubing 10 and air nozzles 1 1 a, 1 1 b, 1 1 c. The second pinch valve PV2 is switched OFF by the second timer 12b and the digital clock C2 for an interval time of 30 minutes. After the interval 30 minutes ends, the second pinch valve PV2 is switched ON again for the next 30 minutes before it is switched OFF again. During the interval time of 30 minutes in which the second pinch valve 6b is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to the shared ozone generator 6a1 through the oxygen flow meter 5. The ozone generated from the shared ozone generator 6a1 is supplied to the second pinch valve PV2 to be distributed to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with a flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water formed in the injection devices 2a, 2b, 2c is distributed to the second plurality of rooms R1 , R2, R3 through the delivery piping system 8.

In the demand-based configuration for producing and distributing ozone, the timebased configuration is replaced by a demand-based configuration once the concentration level of ozone in any of the first plurality of rooms R5, R6, R7 is detected to be above or below the predetermined maximum and minimum concentration level of ozone, respectively. Upon detecting the concentration level of ozone in any of the first plurality of rooms R5, R6, R7 is above a predetermined maximum concentration level by three dedicated ozone sensors 01 , 02, 03, the specific ozone sensor 01 , 02, 03 sends signals to the ozone sterilization control board CB to switch OFF the first pinch valve PV1 to stop the supply of ozone to the rooms R5, R6, R7. Simultaneously, an alert is triggered by visually and/or audibly reflecting the alert with the LED lights 16b and/or buzzer 16c on the ozone sterilization control board CB and simultaneously communicate this alert to the external communication module EM to alert the user. The ozone sterilization control board CB is further configured with a delay timer function capability in which the first pinch valve PV1 is only turned OFF if the collected readings of the concentration level of ozone is maintained for a predetermined period. The delay timer function seeks to prevent the first pinch valve PV1 from switching ON and OFF rapidly due to the potential fluctuation of concentration level of ozone as detected by the ozone sensors 01 , 02, 03. Upon detecting that the concentration level of ozone in any of the plurality of rooms R5, R6, R7 is below a predetermined minimum concentration level by the ozone sensors 01 , 02, 03, the specific ozone sensor 01 , 02, 03 sends signals to the ozone sterilization control board CB to switch ON the first pinch PV1 to start and distribute the supply of ozone into any of the rooms R5, R6, R7. Simultaneously, an alert is triggered to be visually and audibly reflected by the display LED lights 16b and buzzer 16c in the ozone sterilization control board CB and simultaneously sends an alert to the external communication module ECM to alert the user. The adjustment of the level of ozone in the first plurality of rooms R5, R6, R7 can be done either with manual adjustment of the nozzles 1 1 a, 1 1 b, 1 1 c by turning the knob of the nozzles 1 1 a, 1 1 b, 1 1 c or with digital control of the air flow of the nozzle 11 a, 1 1 b, 1 1 c by the ozone sterilization control board CB via remote access through Bluetooth, RF or Wi-Fi network. A delay timer function capability in the ozone sterilization control board CB is similarly used to ensure that the collected readings of the concentration level of ozone is maintained for a predetermined period before any signal is sent to switch ON the first pinch valve PV1 and before a signal is sent to trigger an alert to be visually and/or audibly reflected by the display LED lights 16b and/or buzzer 16c in the ozone sterilization control board. The predetermined maximum and minimum concentration level of ozone in first plurality of rooms R5, R6, R7 is configured and controlled by the ozone sterilization control board CB. The range of predetermined maximum concentration level of ozone in the first plurality of rooms R5, R6, R7 is configured to be between 0.05 ppm and 0.06 ppm and the range predetermined minimum concentration level of ozone in the first plurality of rooms R5, R6, R7 is configured to be between 0.04 ppm and 0.045 ppm. For the delay timer mechanism in the ozone sterilization control board CB, it can be configured by the ozone sterilization control board CB for the readings to be maintained anywhere between 10 to 15 seconds before an alert is triggered by the ozone sterilization control board CB.

In the demand-based configuration for forming and distributing ozone water, the timebased configuration is replaced by a demand-based configuration once there is a demand of water detected in any of the second plurality of rooms R1 , R2, R3. A demand of water detected in any of the rooms R1 , R2, R3 triggers a signal by the ozone sterilization control board CB to open the second pinch valve PV2 to distribute a supply of ozone to the injection devices 2a, 2b, 2c. Each of the injection devices 2a, 2b, 2c is equipped with flow switches 3a, 3b, 3c. When a user opens a water outlet 9a, 9b, 9c in any of the specific rooms R1 , R2, R3, water from the incoming water supply starts to flow into the specific injection device 2a, 2b, 2c. Upon detecting the flow of water above the predetermined minimum amount of water in the injection device 2a, 2b 2c, the flow switch 3a, 3b, 3c sends signals to the ozone sterilization control board CB to supply oxygen to the centralized oxygen generator 4 for supplying oxygen to the centralized oxygen generator 4 to supply oxygen to the shared ozone generator 6a1 to generate ozone. The ozone generated from the shared ozone generator 6a1 is supplied to the second pinch valve PV2 to be distributed to the specific injection device 2a, 2b, 2c to initiate the mixing of the ozone with the flow of water in the injection device 2a, 2b, 2 to form ozone water. The ozone water formed in the injection device 2a, 2b 2c is distributed to the water outlet 9a, 9b, 9c of the specific room R1 , R2, R3 through the delivery piping system 8 in which the water outlet 9a, 9b, 9c is opened. The predetermined minimum amount of water detected in the injection devices 2a, 2b, 2c is configured and controlled by the ozone sterilization control board CB. The range of predetermined minimum amount of water detected in the injection devices 2a, 2b, 2c is configured to be between 6 Ipm and 8 Ipm.

In this embodiment, oxygen is supplied from the centralized oxygen generator 4 to two ozone generators 6a2, 6a3 to generate ozone. The first ozone generator 6a2 is a shared ozone generator in which the ozone generated from the first ozone generator 6a2 is supplied to two pinch valves PV1 , PV2 which is to be distributed to first and second plurality of rooms R5, R6, R7, R1 , R2, R3 which requires ozone and ozone water, respectively. The ozone supplied to the first pinch valve PV1 is to be distributed to the first plurality of rooms R5, R6, R7 through a series of output tubing 10 and air nozzles 1 1 a, 1 1 b, 1 1 c. The ozone supplied to the second pinch valve PV2 is to be distributed to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with the flow of water in the injection devices 2a, 2b, 2 to form ozone water. The ozone water formed in the injection devices 2a, 2b 2c is distributed to the second plurality of rooms R1 , R2, R3 through the delivery piping system 8. The second ozone generator 6a3 receives a supply of oxygen from the centralized oxygen generator 4 to generate ozone to be directly distributed to the third plurality of rooms R13, R14, R15. The centralized oxygen generator 4 is pre-programmed by the ozone sterilization control board CB to be turned ON to generate ozone in the event any one of the two pinch valves PV1 , PV2 and second ozone generator 6a3 is turned ON. In this embodiment, the distributed sterilizer control system CS similarly accommodates the capability of operating in dual configurations of time-based and demandbased controlled by the ozone sterilization control board CB. The operation of the two pinch valves PV1 , PV2 and second ozone generator 6a3 is controlled by the ozone sterilization control board CB to operate in both time-based and demand-based configurations interchangeably.

In the time-based configuration for producing and distributing ozone, the timing of switching ON and OFF of the first and second pinch valves PV1 , PV2 is controlled by the two timers, 12a, 12b paired with the two digital clocks C1 , C2 respectively in the ozone sterilization control board CB. Each of the two timers 12a, 12b and the digital clocks C1 , C2 selectively operates the first and second pinch valves PV1 , PV2 respectively between ON and OFF states by defining the duration of the time intervals for the ON and OFF states. The centralized oxygen generator 4 is pre-programmed by the ozone sterilization control board CB to be turned ON to supply oxygen to the first ozone generator 6a2 to generate ozone in the event either one of the first and two pinch valves PV1 , PV2 is turned ON. According to the predetermined time interval, the first and two pinch valves PV1 , PV2 supplies ozone directly to the first plurality of rooms R5, R6, R7 and supply ozone directly to the plurality of injection devices 2a, 2b, 2c to form ozone water to be dispensed to the second plurality of R1 , R2, R3. The duration of the predetermined time intervals is configured by the user at the ozone sterilization control board CB. For example, in this embodiment, the predetermined interval time is 15 and 30 minutes for the first and two pinch valves PV1 , PV2 respectively. The first pinch valve PV1 is switched OFF by the first timer 12a and a digital clock C1 for an interval time of 15 minutes. After the interval 15 minutes ends, the first pinch valve PV1 is switched ON again for the next 15 minutes before it is switched OFF again. During the interval time of 15 minutes in which the first pinch valve is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to the first ozone generator 6a2 through the oxygen flow meter 5a. The ozone generated from the first ozone generator 6a2 is supplied to the first pinch valve PV1 to be distributed directly to the first plurality of rooms R5, R6, R7 through a series of output tubing 10 and air nozzles 1 1 a, 11 b, 1 1 c. The second pinch valve PV2 is switched OFF by the second timer 12b and a digital clock C2 for an interval time of 30 minutes. After the interval 30 minutes ends, the second pinch valve PV2 is switched ON again for the next 30 minutes before it is switched OFF again. During the interval time of 30 minutes in which the second pinch valve 6b is switched ON, the ozone sterilization board CB sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to the first ozone generator 6a2 through the oxygen flow meter 5b. The ozone generated from the first ozone generator 6a2 is supplied to the second pinch valve PV2 to be distributed to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with a flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water formed in the injection devices 2a, 2b, 2c is distributed to the second plurality rooms R1 , R2, R3 through the delivery piping system 8. In the time-based configuration, the timing of switching ON and OFF for the second ozone generator 6a3 is controlled by a third timer 12c paired with a third digital clock C3 in the ozone sterilization control board CB. The third timer 12c and third digital clock 03 selectively operates the second ozone generator between ON and OFF states by defining the duration of the time intervals for the ON and OFF states. The centralized oxygen generator 4 is pre-programmed by the ozone sterilization control board CB to be turned ON to supply oxygen to the second ozone generator 6a3 to generate ozone in the event the second ozone generator 6a3 is turned ON.

According to the predetermined time interval, the second ozone generator 6a3 supplies ozone to the third plurality of rooms R13, R14, R15. The duration of the predetermined time intervals is configured by the user at the ozone sterilization control board CB. For example, in this embodiment, the predetermined interval time is 20 minutes for the second ozone generator 6a3. The second ozone generator 6a3 is switched OFF by the third timer 12c and the third digital clock C3 for an interval time of 20 minutes. After the interval 20 minutes ends, the second ozone generator 6a3 is switched ON again for the next 20 minutes before it is switched OFF again.

The ozone generated from the second ozone generator 6a3 is directly distributed to the third plurality of rooms R13, R14, R15 through a series of output tubing 10 and air nozzles 1 1 a, 1 1 b, 1 1 c. In the demand-based configuration for producing and distributing ozone, the timebased configuration is replaced by a demand-based configuration once the concentration level of ozone in any of first plurality of rooms R5, R6, R7 is detected to be above or below the predetermined maximum and minimum concentration level of ozone, respectively.

Simultaneously, an alert is triggered by visually and/or audibly reflecting the alert with the LED lights 16b and/or buzzer 16c on the ozone sterilization control board CB and simultaneously communicate this alert to the external communication module EM to alert the user. The ozone sterilization control board CB is further configured with a delay timer function capability in which the first pinch valve PV1 is only turned OFF if the collected readings of the concentration level of ozone is maintained for a predetermined period. The delay timer function seeks to prevent the first pinch valve PV1 from switching ON and OFF rapidly due to the potential fluctuation of concentration level of ozone as detected by the ozone sensors 01 , 02, 03.
