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.
A self-contained, integrated, modular HVAC system includes a plurality of adaptive or interchangeable components or swappable modules interconnected to enable the modulation of total airflow and total cooling capacity (sensible plus latent) to meet variable loads, and adjust a sensible heat ratio (SHR) to meet a variable latent ratio of a conditioned space. The components comprise one or more air inlet, damper, inlet damper, air filtration module, air purification module, air freshener module, dehumidifying module, cooling module, air bypass module, blower module, air outlet, I/O panel, and a control cabinet. The components have sensors and actuators that allows a programmable control system to coordinate diagnostics and operations of internal and external components of a refrigeration/heating cycle using various feedback control logics. The HVAC system allows users to remotely determine a chosen relative humidity (RH) set-point, airflow, and temperature of a conditioned space using wireless data communication devices.

A method and system for providing a user with real-time luminosity, temperature, indoor air quality sensing, diagnostics, analysis, and environmental control via a smart HVAC controller, a plurality of multi-sensor devices and personal health devices and gateways communicably engaged via a mesh network and the Internet. Indoor luminosity, temperature, indoor air quality and HVAC data from a residential or commercial structure as well as occupant health/wellness/ activities status are collected, communicated, and aggregated in an application database via an Internet connection. An application server is operable to query the application database to provide a variety of home status, occupant status, analysis, and diagnostic reports. Reports containing detailed air quality and contaminant data could be communicated to client via email, web/mobile applications, and mobile push notifications. The application may generate one or more remediation recommendations, including configuration, settings, and automatic control of an HVAC system.
Embodiments of the present disclosure enable an HVAC system comprising an adaptive air distribution system, and methods for distributed and adaptive control of an occupant comfort parameter in a localized, distributed space, within a multizone environment. The system comprises an HVAC system controller, sensors, and actuators for the control and distribution of a primary airflow of an HVAC system into a specific zone of a residential or housing unit. The various system elements are configured to adapt operation under a variable sensible or latent internal load gain or change to achieve a desired occupant comfort parameter target set point or occupant ambient target for a distributed zone within a multizone environment. The occupant comfort parameter target set point is configurable through a task ambient management system residing within an application cloud server operably engaged with an application database, the application cloud server being communicably connected to the HVAC system controller.

A smart HVAC system includes a plurality of sensors that monitor the temperature and humidity of a conditioned space and the energy efficiency of the HVAC system. A system controller is operable to control one or more bypass dampers. The modulation of air volume allows the cooling coil to achieve an optimum BTU extraction rate, and regulate temperature and humidity levels of the conditioned space. Sensor data is interpreted by a controller to modulate positioning of the dampers, thereby regulating the volume of air moved across the cooling coil. The smart HVAC system regulates the amount of air moved over the coil according to the desired system output, which includes temperature humidity and energy efficiency while maintaining a constant movement of air and the optimal amount of air exchanges per hour throughout the conditioned space with enhanced dehumidification and mold free systems.
