Background of related art or science

With reference to the patent number 0501002441 , the air conditioning system with the air purification system using compressed air for use in residences and buildings, with the internal air ventilation system installed, is not yet as complete as the invention which is described here. The present invention is composed of a system that filters dust particles and traps undesirable odors, a system that creates pressure to dispense air inside the residences and buildings, the UVC ultraviolet light to kill germs, the electric-charge sterilizer, and the noise-silencing unit, etc.

According to the invention, there is a main electrical component— an electric ventilation fan— which functions to bring outside air into the system to be purified and subsequently dispensed inside residences and buildings. Air is passed through the course particles filter, the activated carbon filter where dust particles are filtered and undesirable odors are trapped, and the ULPA filter which can highly effectively trap minute particles only 0.1 micron in size. The purified air is stored in the purified air storage, where it is prepared before being sent to the heater to increase its temperature to suit residences and buildings situated in a cold climate so that high-temperature air can be dispensed inside the residences and buildings to generate warmth. In the system, there is the UVC ultraviolet light which functions to kill germs. This UVC ultraviolet light is generally used in the fields of medicine and public healthcare for the same purpose. Then, air is sent to a small-diameter tube where the air noise is absorbed and silenced. The small-diameter tube is composed of the electric-charge sterilizer which dispenses conductive anodes and cathode voltages to kill germs in the air before the air is finally sent to the dispenser tube to dispense the purified air inside residences and buildings.

As regards the air passage, air is passed through the passage when the electric ventilation fan sucks the air in and dispenses it. Sucking pressure is created when the outside air is gradually passed through the course dust filter, the activated carbon filter, and the ULPA filter in ways that the electric ventilation fan slowly creates pressure to push the purified air inside the tube to the grille where air is dispensed inside residences and buildings. In so doing, the invented purified fresh air induction system can function quietly and continuously to purify air in an economical manner. Characteristics and intention of the invention

The purified fresh air induction system for residences and buildings consists of an electric ventilation fan which works by bringing in outside air for treatment before dispensing the purified air inside residences and buildings in the following manners:

The first compartment is the first air purification compartment. It contains a course dust filter which filters course dust particles, an activated carbon filter which filters dust particles and traps undesirable odors, and the ULPA filter which is a highly efficient filter that can trap dust particles as small as 0.1 micron in size. This is a standardized air purification filter generally used in a spacecraft or a sterilized room at a hospital, etc. Air is passed through the course dust filter, the activated carbon filter, and the ULPA filter, respectively, before it is transferred to the second compartment.

The second compartment is the second stage where air is treated. The air storage can be larger or smaller than, or similar in size to the first air purification compartment. The second air purification compartment is the place where air is prepared before pressure is created by the electric ventilation fan to suck the air into residences and buildings. The electric ventilation fan sucks a large amount of air inside the second compartment until a vacuum is created inside the compartment, hence there is very little pressure that affects the activated carbon filter and the ULPA filter. This is different from the original system in which the electric ventilation fan is installed parallel to the filter and is also located near the filter, so the sucking pressure of the electric ventilation fan that is trying to suck the air into its center within a limited space can cause the damage to the filter and unnecessarily shortens its life. Also, in the previous system, the filter has to work harder to purify air and its efficiency is inevitably reduced because the filter space is very limited.

The third compartment is the third air purification compartment. It comprises the heater which works to increase the air temperature to ensure suitability for a cold climate and to send the heated air into the inside of the residences and buildings to generate warmth. In addition to the heater, there is the UVC ultraviolet light which functions to kill germs. This UVC ultraviolet light is widely used in the fields of medicine and public healthcare for the same purpose. Then, the air dispensing pressure from the electric ventilation fan sends the treated air to the fourth compartment, where the electric ventilation fan is installed.

The fourth compartment is where the electric ventilation fan is installed. It functions to create pressure to suck in the air from outside the residences and buildings into the first air purification compartment, the second air purification compartment, and the third air purification compartment before sending it to the fifth air purification compartment.

The fifth compartment is the fifth air purification compartment. It is composed of a small- diameter tube which works to silence the air noise and to increase air pressure for transfer of air into residences and buildings. The small -diameter tube transfers air along a non-linear passage so as to further increase the air pressure. There are a certain number of walls installed along the tube, from the beginning to the end of the small-diameter tube, some of which are erected perpendicularly to the small -diameter tube to create a passageway for air whose diameter is smaller than that of the small- diameter tube. Some of the walls are erected alternately on the right side and the left side to create a continuous S-shaped passageway. The purposes are to silence the noise of traveling air, lowering the speed of the traveling air, and to create further air pressure. In addition, in the fifth compartment, the electric-charge air sterilizer is installed. It releases both conductive anodes and cathode voltages in the direct current (DC) which works with the adaptor to release 40-60 Volts DC to kill germs in the air before the air is finally sent to the exit tube to be dispensed inside residences and buildings.

The exit tube connects the passageway from the fifth air purification compartment to residences and buildings. The end of the exit tube is connected to the air-dispensing grille which is installed inside residences and buildings to dispense air inside.

All of the electrical components, including the electric ventilation fan, the heater, the UVC ultraviolet light, and the electric-charge sterilizer are linked to the processor. Part of the processor is linked to the remote control signal receiver which is installed at the air-dispensing grille. It works with the remote control inside the residences and buildings to control the functioning of the purified fresh air induction system, with the display screen installed on the air-dispensing grille to automatically remind the user of required maintenance and to alert the user of functioning errors.

Air is transferred from the first air purification compartment to the second compartment, which is where purified air is stored, the third compartment where air is treated, the fourth compartment where the electric ventilation fan is installed, and the fifth compartment where air is again treated and purified.

The passageway of the air is non-linear. The first air purification compartment and the second air purification compartment are not aligned with the third air purification compartment. The fourth compartment is where the electric ventilation fan is installed, and the fifth compartment is the final stage where air is treated and purified.

The passageway of the air is non-linear. The third air purification compartment and the fourth compartment where the electric ventilation fan is installed are not aligned with the fifth compartment which is the final stage where air is treated and purified.

The passageway of the air is non-linear. The fourth compartment is where the electric ventilation fan is installed. It gradually creates the sucking pressure to allow air from outside the residences and building to seep through the first air purification compartment. Then, the fourth air purification compartment where the electric ventilation fan is installed slowly sucks the air from the second and third air purification compartments and creates pressure to dispense the purified air by slowly pushing it to the fifth air purification compartment, letting air travel along the exit tube to the air-dispensing grille to be dispensed inside residences and buildings. In so doing, this purified fresh air induction system can work quietly and economically.

The aim of this invention is to manufacture a purified fresh air induction system for residences and buildings which does not create loud noises while the system is working and which is especially economical because the system needs to be turned on to work continuously for a long period of time. The main electrical component is the electric ventilation fan which works to bring in the air outside the residences and buildings for treatment before dispensing it inside the residences and buildings.

The aim of this invention is to create a new air induction system within the purified fresh air induction system for residences and buildings which can prolong the life of different system components and parts and which maximizes the efficiency of air purification. The components and parts of an existing purified fresh air induction system are compiled and rearranged to create a new way in which the system functions.

Illustrations I and 2 depict the horizontal purified fresh air induction system, while Illustrations 3 and 4 depict the vertical purified fresh air induction system. It contains the electric ventilation fan (4) which brings in the air from outside the residences and buildings for treatment and purification before dispensing the purified air inside the residences and buildings in the following stages:

The first compartment is the first air purification compartment (1). It contains at least one course dust filter which functions to filter course dust particles, at least one activated carbon filter which filters dust particles and traps undesirable odors, and at least one ULPA filter which is a highly efficient filter that can trap dust particles as small as 0.1 micron in size and which is the standardized air purification filter generally used in a spacecraft or a sterilized room at a hospital, etc. Air is passed through the course dust filter, the activated carbon filter and the ULPA filter, respectively, before it is transferred to the second compartment.

The second compartment is the second air purification compartment (2) where air is treated. The air storage can be larger, smaller, or similar in size compared to the first air purification compartment (1 ). The second air purification compartment (2) is the place where air is prepared before pressure is created by the electric ventilation fan (4) which creates pressure inside the residences and buildings. The sucking pressure of the electric ventilation fan (4) sucks the air in a large space in the second compartment (2) until a vacuum is created, so there is very little pressure that affects the activated carbon filter and the ULPA filter. This is different from the original system in which the electric ventilation fan is installed parallel to the filter and is located near the filter, so the sucking pressure of the electric ventilation fan that is trying to suck the air into its center within a small space can cause the damage to the filter and unnecessarily shortens its life. Also, in the previous system, the filter has to work harder to purify air and its efficiency is inevitably reduced because the filter space is very limited.

The third compartment is the third air purification compartment (3). It comprises the heater (6) which works to increase the air temperature to ensure suitability for a cold climate and to send the heated air into the inside of the residences and buildings to generate warmth. There is the UVC ultraviolet light (7) which functions to kill germs. This UVC ultraviolet light (7) is widely used in the fields of medicine and public health for the sterilization purpose. The air dispensing pressure from the electric ventilation fan (4) sends the treated air to the fourth compartment, where the electric ventilation fan (4) is installed.

The fourth compartment is where the electric ventilation fan (4) is installed. It functions to create pressure to suck in the air from outside the residences and buildings into the first air purification compartment (1 ), the second air purification compartment (2), and the third air purification compartment (3) before sending it to the fifth air purification compartment (5).

The fifth compartment is the fifth air purification compartment (5). It is composed of a small- diameter tube (8) which works to silence the air noise and to increase air pressure for transfer of air into residences and buildings. The small-diameter tube (8) transfers air along a non-linear passage so as to further increase the air pressure. There are a certain number of walls (9) installed along the tube, from the beginning of the small-diameter tube (8) to the end of the small-diameter tube (8). Some of the walls are erected perpendicularly to the small-diameter tube (8) to create a passageway (10) for air whose diameter is smaller than that of the small-diameter tube (8). A number of walls (9) are erected alternately on the right side and the left side to create a continuous S-shaped passageway. The purposes are to silence the noise of traveling air, lowering the speed of the traveling air, and to create further air pressure. In addition, in the fifth compartment, the electric-charge air sterilizer ( I I ) is installed. It releases both conductive anodes and cathode voltages in the direct current (DC) which works with the adaptor to release 40-60 Volts DC to kill germs in the air before the air is finally sent to the exit tube ( 12) to dispense the purified air inside residences and buildings.

The exit tube ( 12) connects the passageway from the fifth air purification compartment (5) to the residences and buildings. The end of the exit tube (12) is connected to the air-dispensing grille (13) which is installed inside the residences and buildings to dispense air inside the residences and buildings.

All of the electrical components, including the electric ventilation fan (4), the heater (6), and the UVC ultraviolet light (7) are linked to the processor (14). Part of the processor (14) is linked to the remote control signal receiver ( 15) which is installed at the air-dispensing grille (13). It works with the remote control inside the residences and buildings to control the functioning of the purified fresh air induction system, with the display screen installed on the air-dispensing grille ( 13) to automatically remind the user of required maintenance and to alert the user of functioning errors.

Air is transferred in a step-by-step process. Air is sent from the first air purification compartment ( 1) to the second compartment (2), which is where purified air is stored, the third compartment (3) where air is treated, the fourth compartment (4) where the electric ventilation fan is installed, and the fifth compartment (5) where air is again treated and purified.

The passageway of the air is non-linear. The first air purification compartment (1 ) and the second air purification compartment (2) are aligned with the third air purification compartment (3). The fourth compartment (4) is where the electric ventilation fan is installed, and the fifth compartment (5) is the final stage where air is treated and purified. The passageway of the air is non-linear. The third air purification compartment (3) and the fourth compartment (4) where the electric ventilation fan is installed are aligned with the fifth compartment (5) which is the final stage where air is treated and purified.

The passageway of the air is non-linear. The fourth compartment is where the electric ventilation fan (4) is installed to gradually create the sucking pressure to allow air from outside the residences and building to seep through the first air purification compartment. Then, the fourth air purification compartment where the electric ventilation fan (4) is installed slowly sucks the air from the second air purification compartment (2) and third air purification compartment (3) and creates pressure to dispense the purified air by slowly pushing it to the fifth air purification compartment (5), letting air travel along the exit tube ( 12) to the air-dispensing grille (13) to dispense purified air inside residences and buildings. This enables this purified fresh air induction system to work quietly and economically.

The end of the exit tube (12) is connected to the passage way of the fifth air purification compartment (5) and is linked to the air-dispensing grille ( 13) which is installed inside residences and buildings to dispense purified fresh air inside the residences and buildings (see Illustrations 1 and 3).
