A real-time system and method for personal air pollution exposure and inhaled dose management is described. A personal device (e.g., smartphone) determines personal exposure and inhaled dose metrics (e.g., daily accumulated dose), and compares daily histories of these metrics with personal health histories (e.g., self-reported daily asthma symptoms/inhaler use) to provide notifications when adverse health effects (e.g., asthma exacerbation) are likely to occur. The system notifications provide a personalized exposure/dose management tool by recommending behavioral changes to reduce exposure/dose (e.g., change time-location, time-physical activities, building operation). These behavioral changes are then used by the system to modify the real-time exposure and dose determined by the system.

Examples herein describe systems and methods for dynamic building ventilation control. A control system can include a controller that receives information from the indoor and outdoor sensor packages. The control system can compare indoor and outdoor air quality using information from the indoor and outdoor sensor packages. The controller can also determine a current operational state of a heating, ventilation, and air conditioning (HVAC) system, such as heating, cooling, and fan status. Based on the air quality comparison and current operational state, the controller can open a first damper and closing a second damper to change ventilation of a building.

The present invention relates to a smart air purifying ventilator installed on a window frame. More specifically, the smart air purifying ventilator of the present invention includes a frame part installed on a window frame and having two or more openings formed therein, a blowing part installed in the frame part and responsible for introducing or discharging air through the openings, filters for purifying air introduced or discharged by the blowing part, an outdoor side cover part coupled to one side of the frame part, a front panel part coupled to another side of the frame part, and a control unit for comparing the inside and outside air conditions of the window frame and controlling the blowing part to determine inflow or outflow of air.

Computer-implemented systems and methods for estimating a replacement status of an HVAC air filter. Outdoor weather data (e.g., outdoor temperature information), is obtained. A Total Runtime Value of the HVAC system is determined based upon the obtained outdoor weather data. Finally, a replacement status of the air filter is estimated as a function of a comparison of the Total Runtime Value with a Baseline Value. By correlating air filter replacement status with an estimated runtime of the HVAC system, a credible predictor of air filter usage is provided. By estimating fan runtime based on easily-obtained outdoor weather data, the methods are readily implemented with any existing HVAC system and do not require installation of sensors or other mechanical or electrical components to the HVAC system.

A dynamic misting control system can supply water to a condenser coil in varying degrees. The control system can include a controller, flow regulator (e.g., pump or separate), and mist generator (e.g., spray nozzles or otherwise). The controller can read outdoor humidity and temperature and vary power to the pump accordingly. The controller can also compare temperatures of the condenser coil to the outdoor humidity and temperature in adjusting the voltage. This can include calculating a voltage based on a first temperature of a coolant supply line and a second temperature in a return line and comparing those temperatures to the outside temperature and humidity.

An HVAC system within a building including a ventilator, a number of sensors, and a control device. The control device has a processor that is configured to receive a request to operate the ventilator. The control device is further configured to determine a status of a minimum runtime mode of the ventilator. The minimum runtime mode operates the ventilator for a minimum amount of each time in a predefined time period. The control device is further configured to determine an air quality value. The air quality value is based on one or more measurements provided to the control device by the plurality of sensors. The control device is further configured to operate the ventilator based on the air quality value being determined to be below an acceptable value.

An air-quality network system for homes, the air-quality network system having an air inlet unit, an air outlet unit, and a monitoring unit. The monitoring unit monitors, measures, and transmits information regarding the air quality to a network. The data management algorithm in the network compares the air quality information against preset/user-defined values and accordingly, determines the operating parameters of the air inlet and/or air outlet units. The system provides real-time monitoring and visualization of the air quality in the home, and provides emergency alerts if air quality exceeds safety limits.
