Definitions
- the present invention relates to demand controlled energy efficient ventilation with air purification device. More particularly the present invention relates to an air purification and ventilation device which can measures the air parameters of indoor and outdoor environment and can able to compare the data and function accordingly.
- excessive moisture can cause the sweating/water drops to develop on windows and doorjambs. This condition is a major health concern and can prematurely deteriorate the windows and doorjambs. Areas of excessive moisture are also breeding grounds for mold, mildew, fungi, dust mites and bacteria. For example, black spots may form on the walls of humid homes, which indicate mildew growth. Mold spores and dust easily become airborne and circulate freely throughout the house, possibly causing a range of illnesses and allergic reactions.
- appliances and vehicles that utilize combustion have the potential for allowing gases such as carbon monoxide and other pollutants, to escape into the air.
- gases such as carbon monoxide and other pollutants
- Some common sources may include gas ranges, water heaters, unvented space heaters, leaky chimneys, and wood burning appliances.
- Today's homes have such high levels of negative pressure, that even a perfectly good chimney or appliance can be back drafted.
- Even breathing can add to the problem when carbon dioxide reaches excessive levels.
- Most building materials used today are treated with many harmful toxins that produce off gases that slowly leak into the home for many years.
- household cleaning products can generate large amounts of pollutants, and there is also a concern about radon seeping from the ground which may cause some health problems.
- ventilation fans have been installed into rooms of homes, such as bathrooms, in order to draw stale air containing moisture and/or pollutants out of the home.
- operating such a fan reduces the overall energy efficiency and creates a severe negative pressure within the home. For instance, with an average run time of 20 minutes for a bathroom fan, approximately 2000 cubic feet of air is drawn out of the house.
- Replacement air is air drawn from outside the house and is unconditioned and unfiltered. This replacement air comes from the paths of least resistance, such as leaky doors and windows, chimneys, water heater vents, gas appliance vents, and attached garage. The replacement air must then be heated or cooled in order to match the inside air temperature. Further, this replacement air can worsen the air quality inside the home.
- the prior art document US5822544A discloses an HVAC system includes an HVAC unit having a cooling mode and a heating mode for conditioning the air in an inside space, and a programmable thermostat located remotely from the HVAC unit.
- the HVAC unit may have an onboard controller configured to control when the HVAC unit is in the cooling mode or heating mode and whether the HVAC unit is activated or not.
- the onboard controller of the HVAC unit may use a common temperature set point when controlling in the cooling mode and the heating mode.
- an HVAC controller and/or server may be programmed to determine if ventilation of a building is desired based, at least in part, on the one or more user- specified air quality thresholds stored in a memory, and one or more of a measure of indoor air quality and a measure of outdoor air quality.
- the air quality parameter threshold may relate to an air quality index, an air pollutant concentration, a smog alert, a pollen count, a dew point, a chance of precipitation, and/or the like.
- the HVAC controller and/or server may take into account current or future weather conditions when determining the ventilation needs of a building. Upon determining that ventilation is needed or recommended, the HVAC controller may send or display a message to the user.
- the message may recommendation that the user open a window or operate a ventilation system, as desired.
- WO2015077453 disclosed the Indoor air quality can be improved by monitoring, with at least one air quality sensor, at least one air quality factor of a target environment.

Description
A DEMAND CONTROLLED ENERGY EFFICIENT VENTILATION WITH AIR PURIFICATION DEVICE
FIELD OF THE INVENTION
The present invention relates to demand controlled energy efficient ventilation with air purification device. More particularly the present invention relates to an air purification and ventilation device which can measures the air parameters of indoor and outdoor environment and can able to compare the data and function accordingly.
BACKGROUND OF THE INVENTION
Indoor air quality has become an increasing concern for new and newly remodelled home owners. Newer model homes over the past couple of decades have become more energy efficient and practically airtight.
Life inside today's airtight homes generates and/or traps moisture and pollutant, dust particles i.e. indoor and outdoor both. Maintaining an ideal humidity in the home can be needed for optimum health. In order to create a comfortable living space, the humidity level in a home should be approximately 40-55%. When humidity levels are less than 40% or more than 60%, pollutant levels rise dramatically. This will cause bacteria, viruses, fungi, mites, respiratory infections, allergic rhinitis and asthma, chemical interactions, and ozone production. With today's tighter homes, too much humidity during all seasons can be problematic.
For example, excessive moisture can cause the sweating/water drops to develop on windows and doorjambs. This condition is a major health concern and can prematurely deteriorate the windows and doorjambs. Areas of excessive moisture are also breeding grounds for mold, mildew, fungi, dust mites and bacteria. For
example, black spots may form on the walls of humid homes, which indicate mildew growth. Mold spores and dust easily become airborne and circulate freely throughout the house, possibly causing a range of illnesses and allergic reactions.
In addition to excessive moisture and biological contaminants, appliances and vehicles that utilize combustion have the potential for allowing gases such as carbon monoxide and other pollutants, to escape into the air. Some common sources may include gas ranges, water heaters, unvented space heaters, leaky chimneys, and wood burning appliances. Today's homes have such high levels of negative pressure, that even a perfectly good chimney or appliance can be back drafted. Even breathing can add to the problem when carbon dioxide reaches excessive levels. Most building materials used today are treated with many harmful toxins that produce off gases that slowly leak into the home for many years. In addition, household cleaning products can generate large amounts of pollutants, and there is also a concern about radon seeping from the ground which may cause some health problems.
In a poor attempt to alleviate these problems, ventilation fans have been installed into rooms of homes, such as bathrooms, in order to draw stale air containing moisture and/or pollutants out of the home. However, operating such a fan reduces the overall energy efficiency and creates a severe negative pressure within the home. For instance, with an average run time of 20 minutes for a bathroom fan, approximately 2000 cubic feet of air is drawn out of the house. Replacement air is air drawn from outside the house and is unconditioned and unfiltered. This replacement air comes from the paths of least resistance, such as leaky doors and windows, chimneys, water heater vents, gas appliance vents, and attached garage. The replacement air must then be heated or cooled in order to match the inside air temperature. Further, this replacement air can worsen the air quality inside the home. During operation of the ventilation fan, for an example when the humidity outside is greater than the inside humidity, humidity levels inside the home may in fact be increased to an uncomfortable level, same is true for other air parameters.
Portable air filters have been used to remove particulates from the air. However, it cannot provide ventilation, Unable to provide filtered fresh air, Indoor as well as outdoor air parameters cannot be measured for smart and energy efficient functioning to control the desired indoor air parameters, free cooling, free heating, free humidification and free dehumidification are not possible.
Various prior art discloses about the energy efficient air ventilation and air purification device. The prior art document US5822544A discloses an HVAC system includes an HVAC unit having a cooling mode and a heating mode for conditioning the air in an inside space, and a programmable thermostat located remotely from the HVAC unit. The HVAC unit may have an onboard controller configured to control when the HVAC unit is in the cooling mode or heating mode and whether the HVAC unit is activated or not. In some cases, the onboard controller of the HVAC unit may use a common temperature set point when controlling in the cooling mode and the heating mode.
Another prior art document US9618224B2 discloses an HVAC controller and/or server may be programmed to determine if ventilation of a building is desired based, at least in part, on the one or more user- specified air quality thresholds stored in a memory, and one or more of a measure of indoor air quality and a measure of outdoor air quality. The air quality parameter threshold may relate to an air quality index, an air pollutant concentration, a smog alert, a pollen count, a dew point, a chance of precipitation, and/or the like. In addition, the HVAC controller and/or server may take into account current or future weather conditions when determining the ventilation needs of a building. Upon determining that ventilation is needed or recommended, the HVAC controller may send or display a message to the user. The message may recommendation that the user open a window or operate a ventilation system, as desired.
Another prior art document WO2015077453 disclosed the Indoor air quality can be improved by monitoring, with at least one air quality sensor, at least one air quality factor of a target environment. Then, based on the collected air quality factor, a HVAC system or an air purification system can be adjusted in order to more efficiently maintain the indoor air quality. Systems that may be used to improve indoor air quality can contain a photo-catalytic oxidation-based air purification system and can communicate with at least one air quality sensor, other purification systems, HVAC system controllers, or a computer configured to monitor and control the air purification systems and HVAC systems.
Another prior art document EP1752715A1 disclosed a ventilation system and a method for driving the same. The ventilation system includes a ventilation unit for exhausting indoor air to an outdoor space and inhaling outdoor air to an indoor space; an air purification unit for purifying the indoor air; an indoor sensing unit for measuring a pollution level of the indoor air; an outdoor sensing unit for measuring a pollution level of the outdoor air; and a controller for determining whether or not the ventilation unit and the air purification unit are operated by comparing the pollution level of the indoor air to the pollution level of the outdoor air.
The aforementioned prior arts encounter various problems which lead into the difficulties in many ways. However, there have been many attempts to provide an air purification systems, but those known to the applications have certain disadvantages like lack of real time monitoring, less energy efficient, high temperature, humidity level, lack of natural ventilation, infiltration, free cooling, free heating etc.
As discussed above, all the known devices having one or more problem like, installation of system, relative humidity, amount of pollutants in the air.

The present invention has solved the problem mentioned above and provided the demand controlled energy efficient ventilation with air purification device as described herein.
