, Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of air filtration and ventilation system. More particularly, the present disclosure relates to a ventilation system for supplying fresh air and controlling air quality inside a location.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In present world, life of people is changing rapidly with rapid increase in population. This increase in population has increased the pollution level to a level which is very dangerous and beyond safe limits for human being and animals. Pollution is directly affecting people of every age, and air pollution is one of the major factors that are causing various health related issues in people. Air pollution is directly affecting the respiratory system of normal people as well as the people already having respiratory disorders or breathing problems.
[0004] Modern indoor structures (such as automobiles, buildings, elevators etc) are being built with increasing emphasis on energy efficiency. This generally means providing more thermal insulation, more vapour barriers and better quality seals around all the inlets and outlets of the indoor structures. This type of construction has given rise to the concern for providing adequate ventilation inside the indoor structures, in light of the need for a continuous supply of fresh air inside the indoor structures.
[0005] Various air ventilation systems or Heating Ventilation and Air Conditioning (HVAC) systems are available in the market, which allows flow of air from an outside location (environment) to the indoor structures. Adding fresh air to the indoor structures accomplishes two primary indoor air quality goals. It pressurizes the indoor structures and increases indoor air quality by diluting polluted or stale indoor air.
[0006] These ventilation or HVAC systems facilitate flow of air from the outside location to the indoor structure. However, these ventilation or HVAC systems fail to consider the quality of air being brought from the outside location into the indoor structures. Increased pollution level in the environment has polluted the air present in the outside environment to an extent that it has become very dangerous and worse than the quality of air present inside the indoor structures. And use of such ventilation or HVAC system for supplying such air inside the indoor structure can be very dangerous for the health of people inside the indoor structures.
[0007] There is, therefore, a need in the art to develop a ventilation system to allow flow of air from one location to another location after comparing the air qualities of the two locations

[00081] In an embodiment, the process can include a step 304 of determining the third concentration of the one or more polluting agents present in the air after being filtered by the one or more air filters 202 based on one or more filtering attributes of the one or more air filters 202
[00082] In an embodiment, the process can further include a step 306 of determining the absorption rate of the filters 202 based on a difference between the first concentration of one or more polluting agents determined at the step 302 and the third concentration of the one or more polluting agents determined at the step 304.
[00083] In an embodiment, the process can include a step 308 of generating a fourth set of signals by the computing unit 112 when the determined absorption rate at the step 406 falls below a predetermined absorption rate of the filters 202. The fourth signal can correspond to a filter replacement alert signal.
[00084] In an embodiment, the proposed system 100 can be configured to transmit the fourth set of signals corresponding to the filter replacement alert signal to the one or more computing devices.
[00085] FIG. 4 illustrates exemplary network architecture in which or with which proposed system and mobile computing devices can be implemented, in accordance with an embodiment of the present disclosure.
[00086] As illustrated, in an embodiment, the system 100 can include a communication unit 114 to connect the system 100 with one or more mobile computing devices 404-1 to 404-3 (collectively referred to as mobile computing devices 404, herein) of users through a network 402. The communication unit 114 can include a WIFI module and a Bluetooth Module, but not limited to the likes. The communication unit 114 can communicatively coupled the mobile computing devices 404 such as a cloud-based server 404-1, a computer/laptop 404-2 and a smart phone 404-3.
[00087] In an embodiment, the system 100 can be configured to transmit the first set of signals, the second set of signals and the third set of signals to the mobile computing devices 404 of the users.
[00088] In an embodiment, the system 100 can be configured to transmit the fourth set of signals corresponding to the filter replacement alert signal to the mobile computing devices 404.
[00089] The network architecture in which or with which proposed device and mobile computing devices can be implemented is described demonstrating a single user and a single device. It is to be appreciated that the present disclosure is not limited to single user or a single device being connected to the mobile computing devices. However, a plurality of users and their devices can be communicatively coupled to the mobile computing devices, and the mobile computing devices can configured to display the readings and report associated with the force being measured by the proposed device.
[00090] User can interact with the mobile computing devices 404 through the network 402 using an application, a web browser, a proprietary program, or any other program executed and operated by the access device. In some embodiments, the access device can communicate directly with the network devices (e.g., communication signal). For example, the access device can communicate directly with network devices using Zigbee™ signals, Bluetooth™ signals, WiFi™ signals, infrared (IR) signals, UWB signals, WiFi-Direct signals, BLE signals, sound frequency signals, or the like. In some embodiments, the access device can communicate with the network devices via the gateways and/or a cloud network.
[00091] Local area network can include a wireless network, a wired network, or a combination of a wired and wireless network. A wireless network can include any wireless interface or combination of wireless interfaces (e.g., Zigbee™, Bluetooth™, WiFi™, IR, UWB, WiFi-Direct, BLE, cellular, Long-Term Evolution (LTE), WiMax™, or the like). A wired network can include any wired interface (e.g., fiber, Ethernet, powerline, Ethernet over coaxial cable, digital signal line (DSL), or the like). The wired and/or wireless networks can be implemented using various routers, access points, bridges, gateways, or the like, to connect devices in the local area network. For example, the local area network can include gateway and gateway. Gateway can provide communication capabilities to network devices and/or access device via radio signals in order to provide communication, location, and/or other services to the devices. The gateway is directly connected to the external network and can provide other gateways and devices in the local area network with access to the external network. The gateway can be designated as a primary gateway.
[00092] The network access provided by gateway can be of any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols. For example, gateways can provide wireless communication capabilities for the local area network 100 using particular communications protocols, such as WiFi™ (e.g., IEEE 802.11 family standards, or other wireless communication technologies, or any combination thereof). Using the communications protocol(s), the gateways can provide radio frequencies on which wireless enabled devices in the local area network can communicate. A gateway can also be referred to as a base station, an access point, Node B, Evolved Node B (eNodeB), access point base station, a Femtocell, home base station, home Node B, home eNodeB, or the like.
[00093] Gateways can include a router, a modem, a range extending device, and/or any other device that provides network access among one or more computing devices and/or external networks. For example, gateway can include a router or access point or a range extending device. Examples of range extending devices can include a wireless range extender, a wireless repeater, or the like.
[00094] A router gateway can include access point and router functionality, and can further include an Ethernet switch and/or a modem. For example, a router gateway can receive and forward data packets among different networks. When a data packet is received, the router gateway can read identification information (e.g., a media access control (MAC) address) in the packet to determine the intended destination for the packet. The router gateway can then access information in a routing table or routing policy, and can direct the packet to the next network or device in the transmission path of the packet. The data packet can be forwarded from one gateway to another through the computer networks until the packet is received at the intended destination
