The present disclosure relates generally to thermostats and, more particularly, to a heating, ventilation and air conditioning (HVAC) system that controls a building or space through the use of a multifunction thermostat.

Background

Thermostats are typically components of HVAC control systems. Conventional thermostats sense the temperature or other parameter (e.g., humidity) of the system and control components of the HVAC system in order to maintain a set point for the temperature or other parameter. Thermostats may be designed to control heating or cooling systems or air conditioners. Thermostats are manufactured in many ways and use various sensors to measure the temperature and other desired parameters of the system.

Conventional thermostats are configured for unidirectional communication with connected components and are used to control HVAC systems by turning certain components on or off or by regulating flow. Each thermostat may include a temperature sensor and a user interface. The user interface typically includes a display for presenting information to a user and one or more user interface elements for receiving input from the user. To control the temperature of a building or space, a user adjusts the set point via a user interface of the thermostat.

Detailed Description

SUMMARY

Referring generally to the figures, a thermal management system and its components are shown according to some embodiments. According to an exemplary embodiment, a thermal management system includes a central thermal management unit (e.g., a chiller, a boiler, etc.) that provides a temperature conditioned (e.g., cooled, heated, etc.) working fluid (e.g., water-based fluid, ethanol, etc.) to a plurality of fluid-based terminal units distributed differently throughout an area (e.g., a room, an office, etc.) of a space (e.g., an apartment, a unit, a home, an office building, etc.). The thermal management system further includes a master controller (e.g., a spatial controller, a central controller, a supervisory controller, etc.) and a plurality of zone controllers distributed differently throughout the zone. Each fluid-based terminal unit may have a corresponding zone controller.

Traditionally, residential thermal management systems have been compiled and set up using components provided and/or manufactured by different sources. These different components prevent the system from gaining full knowledge of the components and how they interact with each other to facilitate efficient real-time control and energy optimization. The thermal management system of the present disclosure includes components that are all provided as a kit or package such that the controller (e.g., master controller, zone controller, etc.) of the thermal management system has pre-programmed knowledge of the components and interactions of the overall system. This pre-programmed knowledge helps to provide a thermal management system (e.g., a water-based thermal management system with distributed fluid-based terminal units for residential use, etc.) that can provide real-time control and energy optimization.

In some embodiments, the thermal management system (e.g., its central controller, its thermal management unit, etc.) is further configured to receive weather forecasts from weather services and/or utility rate information from utility providers. The thermal management system may use the weather forecast along with the utility rate information for model predictive control to optimize (e.g., minimize, etc.) the energy consumption of the thermal management system.

System layout

As shown in fig. 1-4, the thermal/temperature management system, shown as heating and cooling system 50, includes: a master controller, shown as a space controller 100; a plurality of zone controllers, shown as zone controller 200; a plurality of fluid-based terminal units (FBTUs), shown as FBTUs 300; and a central thermal/temperature management unit, shown as a cooler/boiler 400, that includes a thermal management unit controller, shown as a cooler/boiler controller 410. As shown in fig. 1, the components of heating and cooling system 50 are installed within and/or associated with a corresponding space (shown as space 20) (e.g., a unit, apartment building, apartment, city dwelling, office, etc.) of a larger building (shown as building 10). The building 10 may include a plurality of spaces 20 that are proximate to (e.g., above, below, beside, etc.) one another, such as in an apartment building, office building, etc. Each space 20 may include a plurality of sub-spaces or areas (e.g., restaurants, living rooms, bedrooms, bathrooms, kitchens, etc.) shown as rooms 30. According to an exemplary embodiment, the heating and cooling system 50 is configured to thermally manage the temperature within each of the rooms 30 of the corresponding space 20 based on one or more operator settings (e.g., desired temperature settings within the space 20, etc.). In one embodiment, the cooler/boiler 400 includes only coolers so that the heating and cooling system 50 can provide cooling only to the space 20. In another embodiment, the cooler/boiler 400 includes only a boiler so that the heating and cooling system 50 can provide heating only to the space 20. In other embodiments, the cooler/boiler 400 includes only both a cooler and a boiler so that the heating and cooling system 50 is capable of providing both cooling and heating to the space 20. In one embodiment, the cooler and boiler are provided as a single unit. In another embodiment, the cooler and the boiler are distinct units and are separate units. Although a chiller and a boiler are described herein, it should be understood that the chiller/boiler 400 may include any type of HVAC equipment (e.g., heat exchangers, cooling towers, heat recovery chillers, electric heating coils, etc.) configured to add or remove heat from a working fluid and is not necessarily limited to chillers and/or boilers.

As shown in fig. 1, each room 30 within the corresponding space 20 includes an associated zone controller 200 and an associated FBTU 300. In some embodiments, the room 30 includes two or more FBTUs 300. In such an embodiment, a single zone controller 200 may be associated with the two or more FBTUs 300 in a room 30 (or two or more FBTUs 300 in different rooms 30), or there may be a corresponding number of zone controllers 200 in the corresponding room 30. As shown in fig. 2, the cooler/boiler 400 includes a first conduit, shown as an outlet conduit 410, and a second conduit, shown as an inlet conduit 420. An outlet pipe 410 extends between the chiller/boiler 400 and each of the FBTUs 300 of the corresponding space 20 and is configured to provide a thermally conditioned (e.g., heated, cooled, etc.) working fluid (e.g., water-based fluid, ethanol, etc.) to each of the FBTUs 300 of the corresponding space 20. In some embodiments, one or more intermediate heat exchangers are positioned between the cooler/boiler 400 and the FBTU 300 along the outlet conduit 410. An inlet pipe 420 extends between the cooler/boiler 400 and each of the FBTUs 300 of the corresponding space 20 and is configured to receive a working fluid from each of the FBTUs 300 of the corresponding space 20 to form a closed loop. Outlet pipe 410 and inlet pipe 420 thereby fluidly couple cooler/boiler 400 to each of FBTUs 300. As used herein, "fluid coupled" means that two members are directly or indirectly joined to each other such that a fluid (e.g., working fluid, water, etc.) can flow between them either directly or indirectly through an intermediate member.

According to the exemplary embodiment shown in fig. 3, the FBTU 300 is configured as a Fan Coil Unit (FCU) configured to provide temperature controlled air to a zone for heating and/or cooling. In some embodiments, one or more of FBTUs 300 are additionally or alternatively configured as a surface temperature conditioning unit (e.g., a floor and/or ceiling heating and/or cooling unit, etc.) configured to provide heating and/or cooling to a floor and/or ceiling within an area. As shown in fig. 3, each of the FCUs of FBTUs 300 includes a body, shown as housing 310, having a coil, shown as coil 320, and a blower apparatus, shown as fan assembly 330, disposed therein. In some embodiments, FBTU 300 does not include housing 310, but rather its components are disposed below the floor or above a false ceiling without housing 310. The coil 320 includes: an inlet, shown as working fluid inlet 322, coupled to the outlet conduit 410 of the cooler/boiler 400 such that the coils 320 of each of the FCUs receive the thermally conditioned working fluid from the cooler/boiler 400; and an outlet, shown as working fluid outlet 324, coupled to the inlet conduit 420 of the chiller/boiler 400 such that the coils 320 of each of the FCUs return working fluid to the chiller/boiler 400. The fan assembly 330 includes a drive element or actuator, shown as a fan motor 332, coupled to a fan element, shown as a fan 334. The fan motor 332 is configured to drive the fan 334 to generate an air flow. The fan assembly 330 is positioned such that the fan 334 provides an airflow through the coil 320. The thermally conditioned working fluid flowing through coil 320 and the airflow flowing through coil 320 are in heat transfer (e.g., the thermally conditioned or cooled working fluid extracts heat from the airflow to cool the airflow, the airflow extracts heat from the thermally conditioned or heated working fluid to heat the airflow, etc.) to provide an output airflow (e.g., a cooled airflow, a heated airflow, etc.) shown as conditioned airflow 340. The conditioned air flow 340 is provided to a corresponding room 30 of the space 20 associated with the corresponding FCU to thermally condition (e.g., heat, cool, etc.) the temperature within the room 30 to a desired temperature set point. According to an exemplary embodiment, increasing the speed of the fan 334 increases the amount of heat transfer between the working fluid and the airflow, and decreasing the speed of the fan 334 decreases the amount of heat transfer between the working fluid and the airflow.

In some embodiments, each of the FCUs of the FBTUs 300 includes one or more fluid control valves 326 operable to control the flow rate of the working fluid through the coiled tubing 320. Fluid control valve 326 may be positioned upstream of coil 320 along working fluid inlet 322 and/or downstream of coil 320 along working fluid outlet 324. According to an exemplary embodiment, increasing the flow rate of the working fluid through the coil 320 (e.g., by opening the fluid control valve 326 more, etc.) increases the amount of heat transfer between the working fluid and the airflow, and decreasing the flow rate of the working fluid through the coil (e.g., by closing the fluid control valve 326 more, etc.) decreases the amount of heat transfer between the working fluid and the airflow.

The surface temperature conditioning unit of the FBTU 300 may be similarly coupled to the cooler/boiler 400. By way of example, the surface temperature conditioning unit may include a coil (e.g., similar to coil 320, etc.) disposed below a floor of a respective area and/or above a ceiling of the respective area coupled to the cooler/boiler 400. The surface temperature conditioning unit may also include one or more valves (e.g., similar to fluid control valve 326, etc.) for controlling the flow rate of the working fluid through the coil to the floor and/or ceiling and thereby controlling heat transfer from/to the coil.

As shown in fig. 4, the space controller 100 is coupled (e.g., via a wired communication protocol, a wireless communication protocol, etc.) to each of the zone controllers 200, each of the FBTUs 300, and/or the cooler/boiler controller 410. According to an exemplary embodiment, the spatial controller 100 is not directly coupled to the FBTUs 300, but each FBTU 300 is coupled to the spatial controller 100 via a corresponding zone controller 200. In an alternative embodiment, the spatial controller 100 is directly coupled to each of the FBTUs 300. As shown in fig. 4, the spatial controller 100 may also be coupled to: an external device (e.g., a smartphone, a smart watch, a tablet computer, a laptop computer, a computer, etc.) shown as user device 500; a utility provider (e.g., an electricity provider, etc.) shown as utility provider 600; and a weather service provider shown as weather service 650.

The user interface 210 may be configured to receive input from a user and provide output to the user in various forms. For example, the user interface 210 may include a touch-sensitive panel, an electronic display, ambient lighting, a speaker and tactile feedback generator, a microphone configured to receive voice commands from a user, a keyboard or buttons, switches, dials, or any other user-operable input devices. It is contemplated that user interface 210 may include any type of device configured to receive input from a user and/or provide output to a user in any of a variety of forms (e.g., touch, text, video, graphics, audio, vibration, etc.). In some embodiments, the zone controller 200 does not include a user interface 210.

The working fluid temperature sensor may be configured to measure the temperature of the working fluid flowing through the coil 320 of the corresponding FBTU 300. The air quality sensor may be configured to measure any of a variety of air quality variables, such as oxygen levels, carbon dioxide levels, carbon monoxide levels, allergens, pollutants, smoke, and the like. The proximity sensor may include one or more sensors configured to detect the presence of a person or device (e.g., a person in the room 30, etc.) in proximity to the zone controller 200. For example, the proximity sensor may include a Near Field Communication (NFC) sensor, a Radio Frequency Identification (RFID) sensor, a bluetooth sensor, a capacitive proximity sensor, a biosensor, or any other sensor configured to detect the presence of a person or device. The camera may include a visible light camera, a motion detector camera, an infrared camera, an ultraviolet camera, an optical sensor, or any other type of camera. The light sensor may be configured to measure an ambient light level. The sensors 220 may include one or more remotely located sensors (e.g., sensors not located within the housing of the zone controller 200, etc.). The remotely located sensors may be coupled to the processing circuitry 230 via a wired communication protocol or a wireless communication protocol (e.g., over a mesh network, etc.). In some embodiments, the sensors 220 are capable of communicating with each other to facilitate providing information to various controllers or devices within the space 20.

Communication interface 260 may include a wired or wireless interface (e.g., receptacle, antenna, transmitter, receiver, transceiver, wire terminal, etc.) for data communication with various systems, devices, or networks. For example, the communication interface 260 may include an ethernet card and port for sending and receiving data via an ethernet-based communication network and/or a Wi-Fi transceiver for communicating via a wireless communication network. Communication interface 260 may be configured to communicate via a local or wide area network (e.g., the internet, a building WAN, etc.) and may use various communication protocols (e.g., BACnet, IP, LON, MQTT, etc.). The communication interface 260 may include a network interface configured to facilitate electronic data communication between the zone controller 200 and various external systems or devices (e.g., the space controller 100, a corresponding FBTU 300, user equipment 500, etc.).

The processing circuitry 230 is shown to include a processor 232 and a memory 234. Processor 232 may be a general or special purpose processor, an Application Specific Integrated Circuit (ASIC), one or more Field Programmable Gate Arrays (FPGAs), a set of processing components, or other suitable processing components. The processor 232 may be configured to execute computer code or instructions stored in the memory 234 or received from other computer readable media (e.g., CDROM, network storage device, remote server, etc.).

Memory 234 may include one or more devices (e.g., memory units, memory devices, storage devices, etc.) for storing data and/or computer code to perform and/or facilitate the various processes described in this disclosure. The memory 234 may include Random Access Memory (RAM), Read Only Memory (ROM), hard drive storage, temporary storage, non-volatile memory, flash memory, optical storage, or any other suitable memory for storing software objects and/or computer instructions. Memory 234 may include a database component, an object code component, a script component, or any other type of information structure for supporting the various activities and information structures described in this disclosure. Memory 234 may be communicatively connected to processor 232 via processing circuitry 230 and may include computer code for executing (e.g., by processor 232) one or more processes described herein. For example, memory 234 is shown to include an input module 236, a zone capacity module 238, and an FBTU module 240. The functionality of each of these modules is described in greater detail herein.

The input module 236 is configured to receive input (e.g., data, information, commands, etc.) from various sources (e.g., the user interface 210, the sensors 220, the space controller 100, the user device 500, etc.). By way of example, in embodiments where the zone controller 200 includes the user interface 210, the input module 236 may receive target settings for the room 30 in which the zone controller 200 is located from an occupant of the room 30. By way of another example, the input module 236 may be configured to receive data from the sensors 220 regarding conditions within the room 30 in which the zone controller 200 is located (e.g., room temperature, working fluid temperature, humidity, occupancy information, etc.). By way of yet another example, the input module 236 can receive a command from the space controller 100 to provide to the FBTU 300 associated with the zone controller 200. By way of yet another example, the input module 236 may be configured to receive target settings from the user device 500 for the room 30 in which the zone controller 200 is located.

The zone capacity module 238 is configured to determine a current operating capacity of the FBTU 300 associated with the zone controller 200 (e.g., based on fan speed, valve position, etc.). Zone capacity module 238 may then transmit the current operating capacity of FBTU 300 to space controller 100. In other embodiments, zone capacity module 238 collects capacity data for determining the current operating capacity of FBTU 300 and transmits the capacity data to space controller 100 to determine the current operating capacity of FBTU 300. In still other embodiments, at least a portion of the zone capacity module 238 is part of the zone controller 200, the space controller 100, and/or the cooler/boiler controller 410 of the cooler/boiler 400. According to an exemplary embodiment, the zone capacity module 238 is configured to determine the current operating capacity of the FBTU 300 using Proportional Integral (PI) control or Proportional Integral Derivative (PID) control. The current operating capacity is the amount or percentage of the maximum operating capacity of the FBTU 300 that is currently being used to achieve the target set point in the associated room 30 (e.g., 20%, 40%, 50%, 75%, 90% of the maximum operating capacity, etc.). In some embodiments, the current operating capacity of the FBTU 300 is the ratio or percentage of the current speed of the fan motor 332 to the maximum speed of the fan motor 332, the ratio or percentage of the current position of the fluid control valve 326 within the FBTU 300 relative to the maximum open position (e.g., 100% open) of the fluid control valve 326, or a combination or function thereof. In some embodiments, zone capacity module 238 is configured to transmit such an indication to space controller 100 if the current operating capacity of the corresponding FBTU 300 exceeds a maximum operating threshold (e.g., 85%, 90%, 95%, 99%, etc. of the maximum operating capacity). In other embodiments, space controller 100 is configured to determine whether the current operating capacity of each corresponding FBTU 300 exceeds its maximum operating threshold.

The FBTU module 240 is configured to control the operation of a fan motor 332 of a fan assembly 330 of the FBTU 300 and/or the position of a fluid control valve 326 that regulates the flow of working fluid through the FBTU 300 associated with the zone controller 200 to achieve a target setpoint in the room 30 in which the zone controller 200 is located. By way of example, the FBTU module 240 may be configured to control the rotational speed of the fan motor 332 based on a target set point for the room 30, a current temperature within the room 30, and/or a current temperature of the working fluid provided by the chiller/boiler 400 to the coils 320 of the FBTU 300, as well as other possible parameters (e.g., humidity in the room, temperature outside the building 10, temperature of the adjacent room 30, temperature of the adjacent space 20, etc.). By way of another example, FBTU module 240 may be configured to regulate control of fan motor 332 based on commands or instructions received from space controller 100 (e.g., indicating that the temperature of the working fluid provided by chiller/boiler 400 is to be increased, decreased, etc.).

The processor 132 may be configured to execute computer code or instructions stored in the memory 134 or received from other computer-readable media (e.g., CDROM, network storage device, remote server, etc.).

Memory 134 may include one or more devices (e.g., memory units, memory devices, storage devices, etc.) for storing data and/or computer code to perform and/or facilitate the various processes described in this disclosure. Memory 134 may include Random Access Memory (RAM), Read Only Memory (ROM), hard drive storage, temporary storage, non-volatile memory, flash memory, optical storage, or any other suitable memory for storing software objects and/or computer instructions. Memory 134 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described in this disclosure. Memory 134 may be communicatively connected to processor 132 via processing circuitry 130 and may include computer code for executing (e.g., by processor 132) one or more processes described herein. For example, the memory 134 is shown to include an input module 136, an aggregation module 138, a space capacity module 140, a cooler/boiler module 142, an FBTU module 144, a utilities module 146, a weather module 148, and a learning module 150. The functionality of each of these modules is described in more detail below.

The input module 136 is configured to receive input (e.g., data, information, commands, etc.) from various sources (e.g., the user interface 110, the sensors 120, the zone controller 200, the cooler/boiler 400, the user equipment 500, the utility provider 600, the weather service 650, other space controllers 100, etc.). By way of example, the input module 136 may receive target set points from an occupant of the space 20 in which the space controller 100 is located via the user interface 110. By way of another example, the input module 136 may be configured to receive data from the sensors 120 regarding conditions within the space 20 in which the space controller 100 is located (e.g., space/room temperature, working fluid temperature, humidity, occupancy information, etc.). By way of yet another example, the input module 136 may receive capacity information (e.g., capacity data, current operating capacity, etc.) from the zone controller 200 within the space 20 regarding the current operating capacity of each of the FBTUs 300 in the space 20. By way of yet another example, the input module 136 may be configured to receive information regarding a current operating state or parameter of the cooler/boiler 400 (e.g., heating mode, cooling mode, working fluid output temperature, current operating capacity, etc.). By way of yet another example, the input module 136 may be configured to receive target settings for the space 20 in which the space controller 100 is located from the user device 500. By way of further example, the input module 136 may be configured to receive utility pricing data from the utility provider 600. By way of yet further example, input module 136 may be configured to receive weather information (e.g., weather forecast, current outdoor temperature, etc.) from weather service 650.

The aggregation module 138 is configured to aggregate the current operating capacity of each of the FBTUs 300 (e.g., received from the zone controller 200, etc.) to determine a total operating capacity or a space operating capacity. In some embodiments, the aggregation module 138 is additionally configured to determine a current operating capacity of each of the FBTUs 300 (e.g., in embodiments where the zone controller 200 does not determine the current operating capacity of the FBTU 300 but rather transmits capacity data to the space controller 100, etc.).

The space capacity module 140 is configured to compare the space capacity value to a threshold capacity value for the space 20. The threshold capacity value may be based on the number of FBTUs 300 within space 20 and/or the size of each FBTU 300 of space 20. The threshold capacity value may be a percentage of the maximum capacity of the space 20. The threshold capacity value may be based on the number of FBTUs 300 in space 20 (e.g., the maximum capacity (100%) of each FBTU 300 multiplied by the number of FBTUs 300, etc.). In some embodiments, the threshold capacity value is 50% of the maximum capacity of the space 20. In other embodiments, the threshold capacity value of the space 20 is greater than 50% (e.g., 60%, 75%, 80%, etc.) of the maximum capacity of the space 20, or the threshold capacity value of the space 20 is less than 50% (e.g., 40%, 45%, etc.) of the maximum capacity of the space 20.

The cooler/boiler module 142 is configured to send a command or indication to the cooler/boiler controller 410 based on the space capacity value being less than the threshold capacity value for the space 20. The command or indication may include parameters for the cooler/boiler 400 to take action. By way of example, the parameters may include a temperature set point for the working fluid provided by the chiller/boiler 400 to the FBTU 300. The cooler/boiler controller 410 may be configured to regulate an operating parameter or operating point of the cooler/boiler 400 (e.g., independent of the space controller 100, etc.) based on parameters (e.g., temperature set points, etc.) received from the cooler/boiler module 142. Such regulation may facilitate adaptively reducing the energy consumption of the chiller/boiler 400 (e.g., when the FBTU 300 is operating at a higher setpoint, etc.).

The FBTU module 144 is configured to send commands to the zone controller 200 and/or directly to the FBTU 300 to adjust operating parameters or operating points of the FBTU 300 in response to the space capacity value being less than the threshold capacity value of the space 20. By way of example, the FBTU module 144 may be configured to send commands to the zone controller 200 and/or directly to the FBTU 300 to regulate the current output capacity of the FBTU 300 (e.g., by increasing the speed of the fan motor 332, by opening or closing the fluid control valve 326 within the FBTU 300, etc.). In some embodiments, space controller 100 does not include FBTU module 144, and corresponding zone controller 200 is configured to recognize temperature changes of the working fluid provided by chiller/boiler 400 to its associated FBTU 300 and regulate its operation accordingly (e.g., independently of space controller 100, etc.).

As an example, if the space capacity value is less than the threshold capacity value (e.g., these FBTUs 300 are generally under-loaded, etc.) and the heating and cooling system 50 is providing cooling operation within the space 20 (e.g., the air conditioning mode is activated, etc.), the chiller/boiler module 142 may provide a first indication (e.g., with respect to the working fluid temperature set point being raised, etc.) to the chiller/boiler controller 410 so that the chiller/boiler controller 401 may raise the temperature of the working fluid (e.g., water, etc.) provided by the chiller/boiler 400 to the FBTUs 300. The cooler/boiler 400 may thus be controlled by the cooler/boiler controller 410 to perform less cooling on the working fluid in order to reduce the load thereon (e.g., reduce the energy required for its operation, etc.). However, if at least one of the FBTUs 300 reaches its maximum output capacity threshold (e.g., determined based on a signal received from the associated zone controller 200, etc.), the chiller/boiler module 142 may provide a second indication (e.g., with respect to a working fluid temperature set point decrease, etc.) to the chiller/boiler controller 410 so that the chiller/boiler controller 410 may begin to decrease the temperature of the working fluid (e.g., so that the temperature in each corresponding room is maintained and the respective FBTU 300 is not operating above its limit, etc.).

Continuing with the example, if the space capacity value is less than the threshold capacity value (e.g., these FBTUs 300 are generally under-loaded, etc.) and the heating and cooling system 50 is providing cooling operation within the space 20 (e.g., air conditioning mode is activated, etc.), the FBTU module 144 may provide an indication or command to the zone controller 200 and/or directly to the FBTU 300 to increase the rotational speed of the fan motor 332 of the FBTU 300 in order to accommodate the increased temperature of the working fluid provided by the chiller/boiler 400. In embodiments where the space controller 100 does not include an FBTU module 144, the zone controller 200 may be configured to recognize temperature changes in the working fluid provided by the chiller/boiler 400 to its associated FBTU 300 and regulate its operation accordingly (e.g., independently of the space controller 100, to achieve a desired setpoint in the corresponding room, etc.). The FBTU 300 can thus utilize more of its available capacity while reducing the load on the chiller/boiler 400, thereby providing real-time energy savings overall (e.g., because the chiller/boiler 400 typically consumes more energy to operate than the FBTU 300, etc.).

As another example, if the space capacity value is less than the threshold capacity value (e.g., the FBTUs 300 are generally under-loaded, etc.) and the heating and cooling system 50 is providing heating operation within the space 20 (e.g., the heating mode is activated, etc.), the cooler/boiler module 142 may provide a first indication to the cooler/boiler controller 410 (e.g., regarding a reduction in the working fluid temperature set point, etc.) such that the cooler/boiler controller 410 may reduce the temperature of the working fluid (e.g., water, etc.) provided by the cooler/boiler 400 to the FBTU 300. The cooler/boiler 400 may thus be controlled by the cooler/boiler controller 410 to perform less heating of the working fluid in order to reduce the load thereon (e.g., reduce the energy required for its operation, etc.). However, if at least one of the FBTUs 300 reaches its maximum output capacity threshold (e.g., based on a signal received from the associated zone controller 200, etc.), the chiller/boiler module 142 may provide a second indication (e.g., with respect to an increase in the working fluid temperature set point, etc.) to the chiller/boiler controller 410 so that the chiller/boiler controller 410 may begin to raise the temperature of the working fluid (e.g., so that the temperature in each corresponding room is maintained and the respective FBTU 300 is not operating above its limit, etc.). Continuing with the example, if the space capacity value is less than the threshold capacity value (e.g., these FBTUs 300 are generally under-loaded, etc.) and the heating and cooling system 50 is providing heating operation within the space 20 (e.g., the heating mode is activated, etc.), the FBTU module 144 may provide an indication or command to the zone controller 200 and/or directly to the FBTU 300 to increase the rotational speed of the fan motor 332 of the FBTU 300 in order to accommodate the reduced temperature of the working fluid provided by the cooler/boiler 400. In embodiments where the space controller 100 does not include an FBTU module 144, the zone controller 200 may be configured to recognize temperature changes in the working fluid provided by the chiller/boiler 400 to its associated FBTU 300 and regulate its operation accordingly (e.g., independently of the space controller 100, to achieve a desired setpoint in the corresponding room, etc.). The FBTU 300 can thus utilize more of its available capacity while reducing the load on the chiller/boiler 400, thereby providing real-time energy savings overall (e.g., because the chiller/boiler 400 typically consumes more energy to operate than the FBTU 300, etc.).

The utility module 146 is configured to interpret utility pricing data (e.g., electricity costs, etc.) received from the utility provider 600 and affect commands provided by the chiller/boiler module 142 and/or the FBTU module 144 based on the utility pricing data (e.g., using model predictive control, etc.). By way of example, the utility module 146 may predict or forecast price volatility based on past utility pricing history, current utility pricing, current time of day, current date of year, and the like. Thus, when utility pricing is expected to be low, utility module 146 may affect chiller/boiler module 142 and/or FBTU module 144 to provide commands to chiller/boiler 400 and/or FBTU 300, respectively, to increase the loading and energy consumption thereon during lower price times (e.g., such that chiller/boiler 400 provides more cooling to the working fluid during cooling operations, chiller/boiler 400 provides more heating to the working fluid during heating operations, FBTU 300 runs fan motor 332 at a higher rotational speed), thereby utilizing lower pricing and utilizing the thermal capacity of space 20 such that less adjustments may be performed when prices are rising. The heating and cooling system 50 may thus be controlled to drive the temperature slightly above (e.g., when in heating mode, etc.) or below (e.g., when in cooling mode, etc.) the temperature set point (e.g., one degree, two degrees, three degrees, etc.), and then reduce the adjustment output as pricing rises so that the temperature in the space 20 gradually floats back to the temperature set point, thereby reducing energy consumption during higher price times and thereby reducing overall system operating costs. In some embodiments, the utility module 146 is an at least partially cloud-based solution, and the space controller 100 is configured to communicate with the utility module 146 on a remote server via an internet network.

The weather module 148 is configured to interpret weather information (e.g., weather forecast, current outdoor temperature, etc.) received from the weather service 650 and affect the commands provided by the cooler/boiler module 142 and/or the FBTU module 144 based on the weather information (e.g., usage model predictive control, etc.). By way of example, if the temperature is expected to drop and the heating and cooling system 50 is operating in a cooling mode, the weather module 148 may affect the chiller/boiler module 142 and/or the FBTU module 144 to provide commands to the chiller/boiler 400 and/or the FBTU 300, respectively, to reduce loading thereon (e.g., reduce cooling when a reduced external temperature is expected, etc.). By way of another example, if the temperature is expected to rise and the heating and cooling system 50 is operating in a cooling mode, the weather module 148 may affect the chiller/boiler module 142 and/or the FBTU module 144 to provide commands to the chiller/boiler 400 and/or the FBTU 300, respectively, to increase loading thereon (e.g., increase cooling when an elevated external temperature is expected, etc.). Similar operations may be performed when the heating and cooling system 50 is operating in a heating mode (e.g., increasing heating when a drop in temperature is expected, decreasing heating when an increase in temperature is expected, etc.). In some embodiments, the weather module 148 is an at least partially cloud-based solution, and the space controller 100 is configured to communicate with the weather module 148 on a remote server via an internet network.

The learning module 150 is configured to adaptively learn heating and cooling characteristics of the space 20 to optimize control of the cooler/boiler 400 and the FBTU 300 based on thermal interactions between the rooms 30 of the space 20 and/or interactions of the space 20 with adjacent spaces 20 in the building 10. By way of example, the learning module 150 may be configured to identify that the corresponding room 30 (e.g., interior room, etc.) maintains temperature more easily than other rooms 30 (e.g., exterior rooms, etc.) and adjust the commands provided to each of the FBTUs 300 accordingly. By way of another example, the learning module 150 may identify heating and/or cooling patterns in one or more adjacent spaces 20 (e.g., units above, below, beside, etc. the spaces 20) and/or communicate directly with the space controllers 100 in one or more adjacent spaces 20 to receive information regarding heating and/or cooling operations in one or more adjacent spaces 20 and adjust commands provided to each of the chiller/boiler 400 and/or the FBTU 300 accordingly. For example, if the adjacent space 20 maintains the temperature set point at a lower temperature set point than the temperature set point of the space 20 where the space controller 100 is located, the space controller 100 may provide a command for reducing the loading of the FBTU 300 in the room 30 adjacent to the adjacent space 20 (e.g., to take advantage of the temperature difference in the adjacent space 20, etc.). In such embodiments, the space controller 100 may communicate with the space controllers 100 in other spaces directly (e.g., via short-range or long-range wireless communication, bluetooth, Wi-Fi, cellular, radio, etc.), through the cloud via the internet, and/or through a Building Automation System (BAS) to obtain information about neighboring spaces.

Exemplary control Process

Referring now to FIG. 7, a method 700 for operating a thermal management system (e.g., heating and cooling system 50, etc.) is shown, according to some embodiments. At step 702, a master controller (e.g., space controller 100, etc.) receives a target set point (e.g., desired temperature setting, etc.) for a space (e.g., space 20, etc.). The target setting may be received via a user interface of the main controller (e.g., user interface 110, etc.) and/or remotely via a user device (e.g., user device 500, etc.). At step 704, a master controller, a plurality of zone controllers (e.g., zone controller 200, etc.), and/or a thermal management unit controller (e.g., chiller/boiler controller 410, etc.) operates a plurality of FBTUs (e.g., FCUs, floor and/or ceiling heating and/or cooling units, surface temperature conditioning units, FBTUs 300, etc.) and a central thermal management unit (e.g., chiller/boiler 400, etc.) fluidly coupled to each of the plurality of FBTUs to achieve a target set point in each zone of a space (e.g., each room 30, etc.). By way of example, the master controller may provide commands to the thermal management unit controller and the plurality of FBTUs to achieve target setpoints in each region of the space. By way of another example, the master controller may provide commands to the thermal management unit controller and the plurality of zone controllers, wherein each of the plurality of zone controllers provides a respective command to its associated one or more FBTUs to achieve a target setpoint in each zone of the space. By way of yet another example, the master controller may provide an indication of the target setpoints to the thermal management unit controller and the plurality of zone controllers, and the thermal management unit controller and the plurality of zone controllers may control operation of the central thermal management unit and the plurality of FBTUs, respectively, based on the indication to achieve the target setpoints in each zone of the space (e.g., the central thermal management unit and the plurality of FBTUs are not directly controlled by the master controller, etc.).

At step 706, each of the plurality of zone controllers obtains capacity data (e.g., using sensors 220, etc.) to facilitate determining and monitoring a current operating capacity of one or more FBTUs associated with the zone controller (e.g., to achieve a target set point, etc.). In some embodiments, each of the plurality of zone controllers interprets the capacity data to determine a current operating capacity of one or more FBTUs associated with the zone controller, and then transmits information regarding the current operating capacity of the one or more FBTUs associated with the zone controller to a master controller. In other embodiments, the plurality of zone controllers transmit the capacity data to the master controller such that the master controller interprets the capacity data to determine a current operating capacity of each of the FBTUs within the space. At step 708, the master controller aggregates the current operating capacity of each of the plurality of FBTUs to generate a space capacity value. At step 710, the host controller compares the space capacity value to a threshold capacity value.

At step 712, the master controller, the plurality of zone controllers, and/or the thermal management unit controller regulate the operating point of the central thermal management unit (e.g., increase the temperature of the working fluid provided thereby, decrease the temperature of the working fluid provided thereby, etc.) and regulate the operating point of the plurality of FBTUs (e.g., increase the rotational speed of their fans) in response to the space capacity value being less than a threshold capacity value (e.g., indicating that the FBTUs are likely to be operating at a lower load and have available capacity to accommodate a greater loading, etc.). By way of example, the master controller may provide commands to the central thermal management unit to regulate the temperature of the working fluid provided thereby to the plurality of FBTUs, as well as to the plurality of FBTUs to regulate the speed of a fan (e.g., fan 334, etc.) and/or to regulate valves (e.g., valve 326, etc.) of the plurality of FBTUs. By way of another example, the master controller may provide commands to the central thermal management unit to regulate the temperature of the working fluid provided thereby to the plurality of FBTUs, and to the plurality of zone controllers, wherein each of the plurality of zone controllers provides a respective command to its associated one or more FBTUs to regulate the speed of the fan and/or regulate the valves of the one or more FBTUs. By way of yet another example, the master controller may provide a first indication to the thermal management unit controller that the space capacity value is less than the threshold capacity value. The thermal management unit controller may regulate operation of the central thermal management unit to adjust the temperature of the working fluid (e.g., increase the temperature of the working fluid when in the cooling mode, decrease the temperature of the working fluid when in the heating mode, etc.) based on the first indication received from the main controller. The plurality of zone controllers may be configured to recognize, identify, determine, etc., changes in temperature of the working fluid and increase the output of the one or more FBTUs associated therewith (e.g., fan speed, valve opening size, etc.) in order to maintain a desired setpoint in the zone associated therewith.

As an example, if the space capacity value is less than the threshold capacity value and the thermal management system is providing cooling operation within the space (e.g., air conditioning mode is activated, etc.), the central thermal management unit may be controlled to raise the temperature of the working fluid (e.g., water, etc.) provided thereby to the plurality of FBTUs (e.g., the central thermal management unit performs less cooling on the working fluid to reduce the load thereon, etc.), and the FBTUs may be controlled to increase the fan speed and/or valve position of each of the FBTUs (e.g., to cause the FBTUs to utilize more of their capacity and reduce the load on the central thermal management unit, etc.).

As another example, if the space capacity value is less than the threshold capacity value and the thermal management system is providing heating operation within the space (e.g., a heating mode is activated, etc.), the central thermal management unit may be controlled to reduce the temperature of the working fluid (e.g., water, etc.) provided thereby to the plurality of FBTUs (e.g., the central thermal management unit performs less heating of the working fluid to reduce the load thereon, etc.), and the FBTUs may be controlled to increase the fan speed and/or valve position of each of the FBTUs (e.g., to cause the FBTUs to utilize more of their capacity and reduce the load on the central thermal management unit, etc.).

At step 714, the master controller, the plurality of zone controllers, and/or the thermal management unit controller regulate the operating points of the central thermal management unit and the plurality of FBTUs in response to the capacity of at least one of the plurality of FBTUs exceeding a maximum operating threshold (e.g., at least one of the FBTUs is operating at an operating point of 85%, 90%, 95%, 99%, etc. of its maximum capacity). By way of example, the master controller may provide a second indication to the thermal management unit controller in response to the operational set point of at least one of the FBTUs exceeding a maximum operational threshold so that the thermal management unit controller may adjust the temperature of the working fluid so that the FBTU does not have to operate at such a high set point in order to provide a desired condition in the space. The zone controller may then identify a change in temperature of the working fluid and operate at a lower operating set point below the maximum operating threshold while still maintaining the desired conditions in the space.
