Adaptive modular multicoil hvac system

Abstract

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.

         2 . The apparatus of  claim 1  further comprising a scent dispenser coupled to an interior surface of the housing. 
     
     
         3 . The apparatus of  claim 1  further comprising a passive air purifier or an active air purifier coupled to an interior surface of the housing. 
     
     
         4 . The apparatus of  claim 1  further comprising a passive filtration unit or an active filtration unit coupled to an interior surface of the housing. 
     
     
         5 . The apparatus of  claim 1  wherein the controller is configured to dynamically regulate a fan speed of the blower. 
     
     
         6 . An HVAC system comprising:
 a housing comprising a return air plenum and a supply air plenum;   a blower coupled to an interior portion of the housing and operably configured to create an airflow through the housing in a direction from the return air plenum to the supply air plenum;   a first cooling coil coupled to an interior surface of the housing;   a second cooling coil coupled to an interior surface of the housing;   a first motorized damper coupled to an interior surface of the housing and being configurable between an open position and a closed position, wherein the first motorized damper is configured to direct a flow of air across the first cooling coil when configured in the open position;   a second motorized damper coupled to an interior surface of the housing and being configurable between an open position and a closed position, wherein the second motorized damper is configured to direct a flow of air across the second cooling coil when configured in the open position;   a third motorized damper coupled to an interior surface of the housing and being configurable between an open position and a closed position, wherein the third motorized damper is configured to direct a flow of air around the first cooling coil and the second cooling coil when configured in the open position;   a controller operably engaged with the first motorized damper, the second motorized damper, the third motorized damper, and the blower; and   one or more sensors communicably engaged with the controller, the one or more sensors comprising at least one temperature sensor or at least one humidity sensor,   wherein the controller is configured to modulate a position of each of the first motorized damper, the second motorized damper and the third motorized damper in response to an input from the one or more sensors.   
     
     
         7 . The system of  claim 6  wherein the controller is configured to dynamically regulate a fan speed of the blower in response to an input from the one or more sensors. 
     
     
         8 . The system of  claim 6  wherein the one or more sensors further comprise one or more indoor air quality sensors. 
     
     
         9 . The system of  claim 6  further comprising at least one mobile computing device communicably engaged with the controller, wherein the at least one mobile computing device is configured to communicate one or more control inputs to the controller.
