The present disclosure is directed to a uniquely designed air-purification, remote HVAC management, and indoor air quality monitoring system including an online cloud-based platform. In various embodiments, the air purification system is configured for generating a photocatalytic oxidation reaction so as to purify the air traversing through an HVAC unit. The system may be a locally based system that utilizes a specially designed Artificial Intelligence platform for optimizing energy efficiency, enthalpy, and air quality based on continual sensor data collection, indoor air quality measurements, and dynamically adjusted operating parameters. A fault indicator and communications display may also be included.

An air purifier system includes at least one air purifier and a portable user interface device. The user interface device for positioning at a remote location from the at least one air purifier and wirelessly communicated to a controller of at least one of the air purifiers. The user interface device includes a sensor configured to measure an air quality parameter in an area proximate the user interface device for transmission of the air quality parameter to the controller of the at least one of the air purifiers via wireless communication; and a user interface comprising (a) a display for displaying data including at least air quality data from the sensor and (b) a user input control for the user to change one or more functional parameters of the at least one of the air purifiers via the wireless communication.

A system for acquisition and storage of data relative to BACnet objects of a BACnet standard HVAC system having BACnet network, where BACnet objects each generate change data upon occurrence of a change in a value thereof and a controller receives and concatenates the change data of the plurality of BACnet objects into payloads encapsulated into system specific data packets conforming to the BACnet data packet standards and transmitted over the BACnet network. The system also has a data conversion unit receiving the system specific data packets, retrieving the change data therefrom and generating database write commands including the change data. The system also comprises a main data acquisition database in data communication with the data conversion unit and receiving the database write commands therefrom. The main data acquisition database stores the data relative to all data changes of the standard BACnet objects over time.

An air purifier includes: a case in which an inlet is formed at a lower portion thereof and a discharge port opened in a horizontal direction is formed at an upper portion thereof; a purifying unit accommodated inside the case; and air-blowing unit for sucking air into the inlet and allowing the air to pass through the purifying unit, and then blowing the air to the discharge port; an air current control body in which an opening portion that is less in size than the discharge port and opened in the horizontal direction is formed; a lifting instrument for lifting the air current control body; and a rotation instrument for rotating the air current control body.

An HVAC system for enhanced source-to-load matching without sacrificing airflow delivery in low load structures. Embodiments of the present disclosure provide for an HVAC system for enhanced source-to-load matching in a low load environment, i.e. dwellings with a BTU/hour capacity of less than 18,000. Prior art HVAC equipment is oversized for dwellings with a BTU/hour capacity of less than 18,000 that are insulated to minimum code requirements. Embodiments of the present disclosure provide for an HVAC system that separates the delivery of airflow (CFM) output from that of the BTU capacity output, thereby enabling a distributed delivery system for optimal source-to-load matching without sacrificing airflow delivery in low load environments. The source-to-load matching enabled by the present disclosure ensures optimal indoor air quality, enhanced comfort for occupants of the dwelling, and approximately a 60% reduction in heating and cooling costs when compared to prior art HVAC systems.

An air purifying system may include a main air purifier placed in an indoor space, a handheld air purifier mounted on the main air purifier, and an air quality sensor IOT device that communicates with the main air purifier. The air quality sensor IOT device may be fixed in an outdoor space adjacent to the indoor space, or may be carried by a user to measure air quality data while the user travels. The main air purifier may automatically operate based on air quality data received from the air quality sensor IOT device.

A method for controlling air quality in an indoor environment of a building comprises the steps of: storing control values of carbon dioxide and/or volatile organic compound concentration; detecting an instantaneous value of carbon dioxide concentration and sending it to a control unit (5); detecting an instantaneous value of volatile organic compound concentration and sending it to the control unit (5); processing the control values and the instantaneous values of carbon dioxide and volatile organic compound concentration to generate an output signal representative of the detected air quality; sending the output signal to a visual and/or acoustic warning unit (7).

System and methods for counting people in a space that is monitored by a plurality of distributed sensors are disclosed. In some embodiments, the method includes receiving a people count value output by a first sensor monitoring a portion of a space. The first sensor is one of a plurality of distributed sensors monitoring non-overlapping portions of the space. The method further includes waiting to receive additional people count values output by other sensors monitoring other portions of the space and then determining a total count of people in the space in response to receiving the additional people count values and determining that the received people count values are synchronized in time. In response to determining the total count of people in the space, one or more actions may be performed.

An HVAC control system having a cloud-based optimization engine in communication with a local building hub that interfaces with the building HVAC system and room units. The cloud-based optimization engine implements an optimal and predictive control strategy to integrate occupancy prediction, weather forecasting, and modeling of indoor infection risk, indoor air quality, and building energy consumptions. The control strategy includes a model-based predictive control and a model-free reinforcement learning approach. The control strategy considers outdoor weather (both thermal and air quality) conditions, indoor occupancy and requirements for IAQ and infectious risk reduction to decide whether outdoor air should be introduced and how much fresh air will be introduced into the space. Communications with the building hub allow the local HVAC unit to be driven according to the optimization plan. Individual room sensing units can provide local sensor data to the cloud-based optimization engine.

According to one embodiment, a system includes a first and second cooling system, an automation controller, one or more sensors, and a hardware controller separate from the automation controller. The hardware controller processes various temperature set points in conjunction with a timer and configures the activation or deactivation of the first and second cooling systems accordingly.
