[0038] DETAILED DESCRIPTION

[0039]

[0035] While various embodiments of the invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed.

[0040]

[0036] As used herein any reference to ‘’one embodiment” or '‘an embodiment” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

[0041]

[0037] Some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. For example, some embodiments may be described using the term “coupled” to indicate that two or more elements are in direct physical or electrical contact. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. The embodiments are not limited in this context.

[0042]

[0038] As used herein, the terms “comprises,” “comprising.” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that includes a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary7, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or Bis satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0043]

[0039] In addition, use of the “a” or “an” is employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the claimed invention. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.

[0044]

[0040] The terms “heat pump." “exchanger,’’ or “heat exchanger,” as used herein, generally refer a device that facilitates the transfer of heat energy (e.g., between indoor air and outdoor air or between two fluids).

[0045]

[0041] The present disclosure provides methods and systems for heating or cooling. Such methods and systems may enable efficient and rapid heating and / or cooling in vanous contexts, such as heating and / or cooling of an enclosure (e.g., home, office, etc.).

[0046]

[0042] Heating or cooling systems may be used to modulate air temperature, humidity7, or purity of air in an enclosure. Systems utilized to heat or cool an enclosure, like a house, apartment, office, or other structure, may be centralized or decentralized. In some cases, a ductless system may be used to heat or cool a structure. Ductless systems may modulate the temperature in different zones, or rooms, of a structure. Ductless temperature management may occur in a decentralized manner. Ductless systems may utilize temperature differentials between zones in a structure to modulate the temperature in specific zones.

[0047]

[0043] Heat pumps lose efficiency when the temperature delta is large between the indoor and outdoor environment, as the compressor needs to work harder at a higher pressure or temperature differential. This means heat pumps are less efficient in extreme climate events and the peaks of summer and winter. Heat pumps may be networked together at a building and district level.

[0048]

[0044] Many networked heat pump systems comprise a central water line that is maintained at some efficient “goldilocks” temperature (e.g., 20-30°C). Generally, one large HVAC unit (industrial boiler or water chiller) may be engaged to maintain the water loop at this goldilocks temperature (FIG. 12). Then, heat pumps that are connected to the central line utilize the goldilocks temperature water to generate an additional heating or cooling differential for their individual needs. This system can be more effective than having the heat pumps run separately, as the large central system can efficiently supply a large amount of the general load (-70%) and the smaller units can operate at a low temperature delta from the central line rather than the very hot / cold outdoors.

[0049]

[0045] In cases where simultaneous heating and cooling is required, the systems that are opposing the general load of a system actually contribute back into the central loop (FIG. 13). An example of this is the diagram below, where hot water is always needed even when it is hot outdoors. While many of the systems are busy air conditioning the rooms (heating up the central loop) there are sometimes heat pumps that operate in the opposite mode (cooling down the central loop in exchange for heating up domestic water) that assist in maintaining the central loop temperature. This system is useful for buildings with simultaneous heating and cooling needs such as rooms with high solar gain that require cooling while some rooms need hearing.

[0050]

[0046] FIG. 1 illustrates the heating or cooling system 100. In some cases, the heating or cooling system 100 may be a ductless system. The heating or cooling system 100 may comprise zones (e.g., enclosures or rooms) or sub-zones (e.g., areas within an enclosure or room). The heating or cooling system 100 may comprise a refrigerant unit, a hydronics unit, a fluid flow unit, a tracking unit, a power unit, a controller unit, and / or an external remote (e.g., system components).

[0051]

[0047] The heating or cooling system 100 may generate or remove heat in a zone via a refrigerant unit (e.g., refrigerant system or refrigerant cycle). The refrigerant unit may comprise a reversible heat pump.

[0052]

[0048] Some refrigeration systems may contribute to the emission of greenhouse gases due to leaking refrigerants, like hydrofluorocarbons and chlorofluorocarbons. Carbon dioxide (CO2) may be used as an alternative refrigerant with a lower global warming impact than traditional refrigerants. CO2 refrigerants may be non-toxic, non-flammable, and non-corrosive to copper or brass. CO2 refrigerants may operate under high-pressure conditions. The refrigerant working fluid may comprise CO2, propane, isobutane, and / or a natural refrigerant. The refrigerant working fluid may comprise R744, R290, and / or R600A. The refrigerant working fluid may comprise R32, R1234F, R454B, and / or a synthetic refrigerant.

[0053]

[0049] The reversible heat pump may comprise a refrigerant working fluid, a refrigerant liquid line 110, a refrigerant vapor line 111, a compressor 112, a condenser, an evaporator, a reversing valve 1 13, and / or at least one heat exchanger 1 14. One or both of the refrigerant liquid line 1 10 and the refrigerant vapor line 111 may withstand high pressure conditions. One or both of the refrigerant liquid line 110 and the refrigerant vapor line 111 may comprise aluminum, copper, and / or steel. The refrigerant liquid line 110 may have an external diameter of about 1 / 8 inch to about 1 / 2 inch. The refrigerant liquid line 110 may have an outer diameter greater than or equal to about 1 / 8, 1 / 4, 3 / 8, or 1 / 2 inch. The refrigerant liquid line 110 may have an outer diameter less than or equal to about 1 / 8 inch to about 1 / 2 inch. The refrigerant liquid line 110 may have an outer diameter between two values described herein, for example between about 1 / 8 inch to about 1 / 2 inch. The refrigerant vapor line 111 may have an external diameter of about 1 / 8 inch to about 1 / 2 inch. The refrigerant vapor line 111 may have an outer diameter greater than or equal to about 1 / 8, 1 / 4, 3 / 8, or 1 / 2 inch. The refrigerant vapor line 111 may have an outer diameter less than or equal to about 1 / 8 inch to about 1 / 2 inch. The refrigerant vapor line 111 may have an outer diameter between two values described herein, for example between about 1 / 8 inch to about 1 / 2 inch.

[0050] The compressor 112 may circulate the refrigerant working fluid. The compressor 112 may mechanically compress the refrigerant working fluid. The compressor 112 may convert the refrigerant working fluid from a low temperature, low pressure liquid state to a high temperature, high pressure vapor or gas state.

[0054]

[0051] The condenser may dissipate heat from the refrigerant working fluid. The condenser maybe a gas cooler. A gas cooler may be utilized when the refrigerant working fluid is transcritical. The condenser may convert the refrigerant working fluid from a high temperature, high pressure gas state to a high temperature, high pressure liquid state. The evaporator may absorb heat into the refrigerant working fluid. The evaporator may convert the refrigerant working fluid from a high temperature, high pressure liquid state to a high temperature, high pressure gas state.

[0055]

[0052] The reversing valve 113 may direct or reverse the flow of the refrigerant working fluid through the refrigerant unit. When the reversing valve 113 reverses the flow of the refrigerant working fluid, the condenser may act as an evaporator and the evaporator may act as a condenser. The expansion valve 114 may remove pressure from the refrigerant working fluid. The expansion valve 114 may convert the refrigerant working fluid from a liquid state to a gas state. The at least one heat exchanger 114 may transfer heat between the refrigerant system, the hydronics system, and / or the fluid flow system, as described herein.

[0056]

[0053] The heating or cooling system 100 may exchange heat between zones via a hydronics unit (e.g. hydronics system or hydronics cycle). The hydronics unit may comprise a manifold 120, a hydronics working fluid, a hydronics fluid pump 121. a hydronics fluid line, and / or at least one exchanger 1 14. The exchanger 1 14 may be a heat exchanger. The exchanger 1 14 may be a brazed plate heat exchanger. The hydronics unit may transfer heat between zones that is passively generated by temperature differentials. The temperature differentials may be between the temperatures of individual zones or between the exterior and interior of the structure. The hydronics unit may transfer heat between zones that is actively generated by the refrigerant unit.

[0057]

[0054] The hydronics system may comprise a manifold 120 (e.g., hydromanifold), which may be a dynamic smart manifold. The manifold 120 may be configured to selectively direct movement of the hydronics working fluid through the hydronics fluid line (e.g., in a loop configuration), as further demonstrated in FIG. 19. The manifold 120 may comprise an actuating valve. The manifold 120 may facilitate system components or devices to interface with the thermal network comprised in the indoor unit, outdoor unit, and reversible heat pump unit. The manifold 120 may alter loop configurations of the hydronics working fluid. The actuating valve may comprise multiple valve positions in a single form factor (as compared to a pipe-based valving system). Thus, the actuating valve may comprise a smaller form factor and number of input and output hydronic ports than a pipe-based valving system.

[0055] The manifold 120 may be configured in many-to-many configurations. The manifold 120 may comprise varied combinations of mechanisms and port connection configurations.

[0058]

[0056] The dynamic manifold may be directed by the controller. The manifold may be governed by a control algorithm to adjust the flow loop for optimal performance based on system or user needs. The hydronics working fluid may comprise water, glycol, propanediol, propylene glycol, and / or ethylene glycol. The hydronics fluid pump 121 may operate on a voltage of about 10 to about 20. The hydronics fluid pump 121 may operate on a voltage greater than or equal to about 10 to about 20. The hydronics fluid pump 121 may operate on a voltage less than or equal to about 10 to about 20. The hydronics fluid pump 121 may operate on a voltage between two values described herein, for example between about 10 to about 20. The hydronics fluid pump 121 may be configured to control movement of the hydronics working fluid through the hydronics fluid line. The hydronics fluid pump 121 may be a dynamic pump or a positive displacement pump. The hydronics fluid pump 121 may comprise a filter.

[0059]

[0057] The hydronics fluid line may be flexible, easy to install, not rigid, and / or insulated. The hydronics fluid line may comprise rubber or plastic. The hydronics fluid line may comprise a hose, at least two hoses, and / or a metal sleeve. The hydronics fluid line may comprise a data cable. The hydronics fluid line may be surrounded by an insulation layer. The hydronics fluid line may have an outer diameter of about 5mm to about 40mm. The hydronics fluid line may have an outer diameter greater than or equal to about 5mm to about 40mm. The hydronics fluid line may have an outer diameter less than or equal to about 5mm to about 40mm. The hydronics fluid line may have an outer diameter between two values described herein, for example between about 5mm to about 40mm. The hydronics fluid line may have a wall thickness of about 0.1mm to about 10mm. The hydronics fluid line may have a wall thickness greater than or equal to about 0. 1mm to about 10mm. The hydronics fluid line may have a wall thickness less than or equal to about 0. 1mm to about 10mm. The hydronics fluid line may have a wall thickness between two values described herein, for example between about 0.1mm to about 10mm. The insulation layer may have a wall thickness of about 2mm to about 20mm. The insulation layer may have a wall thickness greater than or equal to about 2mm to about 20mm. The insulation layer may have a wall thickness less than or equal to about 2mm to about 20mm. The insulation layer may have a wall thickness between two values described herein, for example between about 2mm to about 20mm.

[0060]

[0058] The hydronics fluid line may comprise at least two central lines (FIG. 15). The hydronics fluid line may comprise a desired line. The hydronics fluid line may comprise a waste line. The desired line may distribute the desired temperature load across the heating and cooling system 100. In the summer, the desired temperature load is generally cooling (cold water) and in the winter the desired temperature load is generally heating (hot water). The desired line may facilitate any indoor unit within the heating and cooling system 100 to received desired energy from any heat pump. The desired line may facilitate multiple indoor units to work in series, regardless of the number heat pumps available. The desired line may facilitate multiple heat pumps to combine refrigeration capacity in a parallel format. The desired line may facilitate smaller devices that do not have a heat pump cycle built into them (e.g., a refrigerator) to receive cooling capacity from an outdoor unit, removing the traditional refrigeration components that exist in an enclosure and allowing for more storage space and unique geometries.

[0061]

[0059] The waste line may dissipate waste from the heat pumps into the various outdoor units and provides an interface for non-heat pump waste dissipation methods such as geothermal. The goal of the waste line is to be at a neutral temperature to reduce lift for all heat pumps operating on the waste line. The closer this line is to a neutral or even desired temperature, the higher COP all heat pumps connected to the waste line will operate at.

[0062]

[0060] The waste line temperature may vary' between a low entropy state (pure waste) and a medium temperature neutral state that collectively reduces the lift of the heat pumps across the cascade system.

[0063]

[0061] In cases involving simultaneous reutilization of waste (i.e., a water heater in the summer), the waste line is temporarily kept in a low entropy waste state. Prioritizing the waste compacting by the heat pumps and not engaging the outdoor units responsible for waste removal or by engaging a thermal battery that has stored low entropy waste prior may facilitate reutilization. The use of this low entropy waste in a hydronic cascade may significantly reduce the lift of another heat pump working in the opposite direction, where the waste of one system is the desired heat of another.

[0064]

[0062] When low entropy waste is not needed or an additional thermal battery has been sufficiently charged, the heating and cooling system 100 may transition to a waste reduction state which focuses on pushing the waste line temperature as close to desired as possible.

[0065]

[0063] Informed by telemetry7, occupancy, and building data, the hydronics system and the manifold 120 may autonomously expel or absorb heat between the central line and the room.

[0068]

[0066] The ERV 130 may modulate moisture or humidity levels throughout the heating and cooling system 100 when there is a moisture or humidity differential between the interior and the exterior of the structure. The heating or cooling system 100 may form a condensate. The ERV 130 may maintain or modulate the moisture of the interior fluid by expelling the condensate into the exterior fluid or the interior fluid. The hydronic system may heat the ERV 130. A resistive heating method may heat the ERV 130. A line drawing on the hot refrigerant line may heat the ERV 130. Heating the ERV 130 may prevent freezing and / or long-term buildup of moisture and / or condensate.

[0067] The ERV 130 may facilitate fresh air exchange. The ERV 130 may facilitate ventilation for climatic reasons such as wildfire, pollen, and pollution. The ERV 130 may comprise a two- stage push-pull ERV built with a porous honeycomb ceramic core. The porous honeycomb ceramic core may provide efficient performance and supply chain availability.

[0075]

[0074] The light sensors may instruct a coupled unit to operate at quieter indoor modes when lights are off and occupants are detected (e.g., sleep mode). The light sensors may instruct a coupled unit to operate louder more powerful modes when lights are on and occupants are not detected (e.g., passively occupied). Various visual and auditory sensors may be combined with time, weather, and historical data to modulate indoor fan speed and improve acoustic behavior over time.

A system component may be telemetrized and equipped with software for constant monitoring, logging, and distribution to a cloud or central network.

[0085]

[0084] The controller unit may improve efficiency as compared to a system comprising an HVAC unit and home appliances, which may possess limited interfacing capabilities due to complex building management control software and little to no shared telemetry between system components. The controller unit may improve efficiency as compared to systems comprising largely analog devices that monitor little amounts of telemetry for safety stops and other overload situations. The controller unit may improve efficiency as compared to systems that have limited capacity only to monitor power utilization patterns, but may not log or upload data that may inform machine learning training.

[0086]

[0085] By monitoring the performance, thermal states, and utilization patterns of the system components, the controller unit may continuously build an HVAC model of a building, enclosure, or zone to inform cooperativeness and efficiency of the system components.

[0087]

[0086] Some components in the hydronics system may involve mass-sharing or water loops that are intertwined between each other. Even with the addition of an expansion tank to support a varying hydronics working fluid (e.g., water) loop mass, control loops may facilitate regulation of the input and output of water into fixed loops. The controller unit may perform time division multiplexing, which ensures that heat pumps, outdoor units, and indoor units add and subtract hydronics working fluid (e.g., hydronic mass) into the loops based on a schedule.

[0088]

[0087] The controller unit may facilitate the heating and cooling system 100 to be adaptable to buildings that vary in size, number of enclosures, number of coupled units, length of lines, HVAC parameters, etc. Thus, the controller unit may improve efficiency as compared to systems developed only for specific use cases with networks carefully designed for specific building requirements. The heating and cooling system 100 may thus be a direct-to-consumer product that proposes a modular and scalable building-wide hydronic system. Further, the heating and cooling system 100 may provide a generalizable approach to HVAC control and heat distribution for scaling into various buildings. The controller unit may facilitate in-situ and lifelong learning, where individual system components and the entire heating and cooling system 100 progressively learn over time to effectively distribute and reutilize energy within the system 100. System components may be equipped with a minimum amount of compute capacity and cloud capacity for model training and deployment.

[0089]

[0088] The controller unit may utilize at least one of traditional PID control, model predictive control, physics-constrained neural networks, CNNs, LSTMs, deep reinforcement learning, or other machine-learning driven approaches to improve the performance of system components (e.g., indoor units, outdoor units, and heat pumps) at a device level and network level. Management of data, training, deployment, and networked control may be facilitated by the inclusion of sensors, computational capacity, cloud connectivity, and connection interfaces such as Ethernet and WiFi in the system components.

[0090]

[0089] The controller unit may monitor the lifespan of the impulse. The controller unit may provide an alert before or when the impulse may reach the lifespan terminus.

The battery-powered dial depicted in FIG. 9C may control the nearest system component (e.g., coupled unit). The battery-powered dial may set or indicate the airflow, temperature, or behavior of a system component, similarly to that of the onboard panel. With included mounting accessories, the dial may be magnetically attached to a wall or charging platform when not being remotely used. The dial may also be configured to perform remote sensing of air characteristics and quality. The remote sensor may facilitate close responses to the HVAC needs of an enclosure at a spatial level to prevent over-running of a system component due to hot or cold spots in the enclosure.

[0093]

[0092] The heating or cooling system 100 may accept user inputs via integration with a wall- mounted thermostat. The wall-mounted thermostat may utilize pre-existing thermostat wiring in an enclosure.

The controller unit may be directly or natively integrated with a BMS controller to provide secure, scalable connectivity' and facilitate rapid commissioning of building automation and data management solutions.

[0095]

[0094] The heating or cooling system 100 may accept user inputs via an app. either via desktop or web view (FIG. 9A) or a mobile app (FIG. 9B). The app depict multiple system components or enclosures. The app may utilize accessible wireless interfaces such as RFID / Bluetooth to upload Wi-Fi credentials and connect to system components or other devices. The app may facilitate further control and monitoring of system efficiency (COP and energy utilization), refrigeration and hydronics system telemetry (pressures, temperatures, flow' rates, etc.), error and maintenance notifications, and an interface to control and monitor fleets of system components (e.g., coupled units) across a building. Thus, the app may facilitate control of pow er, temperature settings, and maintenance schedules autonomously in an easy-to-access GUI.

The indoor units and outdoor units 310, 311, 312 each may comprise a refrigerant unit 320, 321, 322. The refrigerant units 320, 321, 322 may exchange heat with the hydronics units 330, 331, 332 via the heat exchangers 340, 341, 342. In some cases, refrigerant unit 320 may exchange heat with hydronics unit 330 and / or hydronics unit 332 via heat exchanger 340.

Similarly, coupled units 311 may be connected to coupled units 312 by hydronics unit 331. Similarly, coupled units 312 may be connected to indoor coupled units 310 by hydronics unit 332. The hydronics units 330, 331, 332 may carry heat between the coupled units 310, 311, 312 via the hydronics working fluid. The heating or cooling system 300 (100) may comprise additional coupled units, refrigerant units, and / or hydronics units. These additional units may expand the heating or cooling system 300 (100) to incorporate additional zones or accommodate a larger structure footprint.

[0105]

[0102] A heat exchanger may comprise a fan coil unit (FIG. 17). By standardizing the medium of energy transfer to the hydronics working fluid (e.g., water) in an outdoor unit, a fully hydronic waste dissipation method facilitates for any number of size and shaped fan coil units to be networked together to collectively act as one heat exchanger. Thus, the heating and cooling system 100 facilitates a flexibility to achieve architectural integration, since all surfaces that are architecturally available can act as fan coil heat exchangers to maximize the surface area for heat dissipation in order to improve capacity and efficiency of a heat pump.

[0106]

[0103] The heating and cooling system 100 may comprise outdoor or indoor fan coils of different sizes, footprints, protrusions off the wall, optionally recessed, airflow methods (crossflow, axial, centrifugal) based on structural, architectural, electrical, and environmental parameters (e.g., noise).

[0107]

[0104] The heating and cooling system 100 may further comprise indoor radiant paneling or outdoor radiant paneling. Radiant paneling may be interfaced with the heating and cooling system 100 to temper enclosures or dissipate waste. Within an enclosure, a hydronics fluid line may cool or heat floors or walls of the enclosure without the use of an indoor fan coil unit. The heat pumps may be compatible with off-the-shelf radiant solutions.

[0108]

[0105] Outdoor radiant paneling may be configured to make every surface of a building a heat exchanger for waste dissipation. An outdoor radiant panel may comprise a hydronic radiant panel or tile for walls and roofs. An outdoor radiant panel may be configured to absorb and release heat as needed by the heating and cooling system 100. Roof tiling may facilitate heat absorption in cold conditions (e.g.. the winter) when ambient air temperature is much colder than the temperature of the roof in direct sunlight. Compared to solar panels, which may suffer from reduced efficiency in high temperatures, the roof tiling may be used for simultaneous photovoltaic (PV) cooling and hot water generation. Generally, the roof is a surface that interacts with sunlight, air, and water (in rain) and may utilized for absorption and extraction of heat with the heating and cooling system 100.

[0109]

[0106] Heat recovery in radiant wall paneling may be conceptualized as increasing the insulation (e.g., R-value) of a wall. Home insulation is one of the largest factors in building efficiency but can be challenging improve in a retrofit scenario. Neutral temperature w ater flowing through a radiant wall panel may provide a low cost way to dramatically improve the wall insulation capacity of existing buildings.

[0110]

[0107] The heating and cooling system 100 may further utilize thermal battery storage. A thermal battery may comprise a buffer tank for the storage of heated / chilled w ater. A thermal battery system may comprise the same manifold and flow- structure as a fan coil unit (i.e., a fan coil dumps energy into air. a thermal battery dumps energy into a tank). The manifold used to modulate between the desired and waste lines in a fan coil may be directly reutilized for a thermal battery.

[0108] A thermal battery may facilitate a heat pump in prioritizing running and producing heat or cold when energy and electricity is cheap. A thermal battery’ may facilitate the system in optimizing based on other time-based factors. For example, in a desert or climates where temperature varies significantly based on the time of day, the waste of one time of day (heat in the day or cold at night) is the desired energy of the other time of day. In some cases, where simultaneous heating or cooling is required offset by some period of time, a thermal battery may temporarily store low entropy waste to be reutilized later by another heat pump.

[0111]

[0109] Thermal battery storage may' not be limited to an insulated water tank. Through the hydronics system, mediums and storage methods of all ty pes may easily interface with the heating and cooling system 100. Indoor fan coils may utilize the indoor air of unoccupied rooms such as attics and basements as batteries. A pool heater (or chiller) may facilitate the use of the large thermal mass of a pool to act as a thermal battery when the pool is not in use (e g., during the winter).

[0112] [HO] The heating and cooling system 100 may further connect to off-grid peripherals such as rainwater catchment / storage tanks. In some cases, a rainwater collection system may double as a thermal battery as well offering a dual-purpose product for domestic water collection and HVAC. [Hl] A thermal battery' may further accept excess charge in a curtailment scenario (e.g., when renewable energy’ sources produce excess energy’ within the heating and cooling system 100). During a curtailment scenario, the thermal battery may supplement existing battery solutions in an enclosure or building to accept and store excess grid power.

[0113]

[0112] A thermal battery’ with a hydronic capacity may improve efficiency and energy reutilization. A thermal battery' may also be useful in emergency situations and natural disasters where extended heating and cooling is needed when power is unavailable. In contrast, some systems may be inoperable during a power outage and may lead to significant loss of life if an outage occurs in harsh summer or winter conditions. A thermal battery-based distributed hydronics system may maintain some capacity' to minimally heat or cool environments in an emergency scenario based on pure hydronic capacity7. Radiant system components may not need additional battery’ power other than to run a pump. Fan coil system components may utilize both a pump and fan, which may use significantly less power than running a vapor compression cycle on battery backup power.

[0114]

[0113] The heating and cooling system 100 may further connect to geothermal systems and wells to dissipate waste beyond ambient. Any available ocean, aquifers, rivers, and lakes near or on a property may similarly provide a water-based interface to boost the performance of the heating and cooling system 100.

[0114] The water-water heat pumps disclosed herein may create a majority of the capacity of the heating and cooling system 100. Other heat pump devices may be cascaded into the heating and cooling system 100 to act as peripheral heat pumps. Such other devices may comprise refrigerators, freezers, buffet carts, heat pump dryers, domestic water heaters, ice makers, wine chillers, pool heaters, saunas, dehumidifiers, greenhouses, etc.

[0115]

[0115] The heating and cooling system 100 may at a home or district level may architecturally integrate every surface and open space for the purposes of heat recovery and release and to interface every device in a building to utilize this capacity of energy to dramatically reduce the energy7utilization at a building and city level.

[0116] FIG. 4 illustrates how a fluid may flow through the at least two plenums or the doubleplenum assembly. The at least two plenums 401, 402 (e.g., double plenum assembly) may be coupled to the impeller at a junction 403. The fluid may flow into the at least two plenums 401, 402 from the impeller at the junction 403. The fluid flow through the first plenum (e.g., first fluid flow) may be depicted by the arrows 404 (FIGs. 4A-4C). The fluid flow through the second plenum (e.g.. second fluid flow) may be depicted by the arrows 405 (FIGs. 4A-4C). The first fluid flow and the second fluid flow may combine to provide a resultant fluid flow. The resultant fluid flow may be depicted by the arrows 406 (FIG. 4C). The fluid may flow from the at least two plenums 401, 402 to the enclosure via the vents 407.

[0117]

[0117] A louver 408 may articulate to direct the fluid flow from the impeller to one or both of the at least two plenums 401, 402. The louver 408 may direct the fluid from the impeller to the first plenum 401 by articulating fully into a first position (FIG. 4A). The louver 408 may direct the fluid from the impeller to the second plenum 402 by articulating fully into a second position (FIG. 4B). The louver 408 may direct the fluid from the impeller to both the first plenum 401 and the second plenum 402 by articulating between the first position and the second position (FIG. 4C). The louver 408 may maintain a static position between the first position and the second position. The louver 408 may articulate in an oscillating manner between the first position and the second position.

[0118]

[0118] The at least two plenums 401, 402 may each comprise an airfoil 409, 410. The airfoil 409 may be configured to direct the first fluid flow 404 as it exits the vents 407 in the first plenum 401 to have a first direction. The airfoil 410 may be configured to direct the second fluid flow 405 as it exits the vents 407 in the second plenum 402 to have a second direction. The first fluid flow 404 may be perpendicular to the second fluid flow 405. Similarly, the first direction may be perpendicular to the second direction. The combination of the first fluid flow and the second fluid flow may produce the resultant fluid flow 406 based on vectoring effects. The louver 408 may articulate between the first position and the second position based on input from the controller system and / or tracking system. The controller unit may articulate the louver 408 to modulate the direction of the resultant fluid flow 406.

[0119]

[0119] Thus, a double plenum assembly may provide a resultant fluid flow 406 with a 90° range of motion. When the fluid flow unit comprises at least two impellers, where each impeller is coupled to a double plenum assembly, the fluid flow unit may provide two resultant fluid flows 406. Thus, the fluid flow unit may provide a 180° range of coverage to the enclosure.

[0120]

[0143] FIGs. 7-8 and 10-11 demonstrate an alternative configuration of the system components comprising a unified Packaged Terminal Heat Pump (PTHP) configuration that can be comprised in an existing Packaged Terminal Air Conditioner (PT AC) sleeve.

[0148]

[0144] The PTHP configuration comprises refrigeration, electrical, and software components of the coupled units described herein. The PTHP configuration measures 15.75” H x 41.75” W x 17.5 ”D and fits into existing PTAC sleeves with a 32% slimmer profile than conventional products. The PTHP configuration may be one of the thinnest PTAC units in the market. The PTHP configuration may only protrudes 5” from the inner wall when installed with a standard 16” x 42” wall sleeve. The PTHP configuration may further comprise modular trim attachments to fit into non-standard openings. The PTHP configuration may weighs 108 pounds. The PTHP configuration may be hermetically sealed with 16 ounces of pre-charged R32 refrigerant for the heat pump module and a propylene glycol hydronic mixture in the fan coil system.

[0149]

[0145] The PTHP configuration specifications may meet the requirements of a building owner and management, with added advantages in customization, aesthetics, performance, and expandability’ (Table 1).

[0150] TABLE 1: PTHP Configuration Specifications

[0146] The PTHP configuration may comprise a PTAC sleeve and modular trim, and gasket attachments for gaps between the unit and the wall. The sealed heat pump module may be isolated from the rest of the hydronic loops and thoroughly insulated, preventing thermal losses between components. Insulation may also built into the paneling to avoid condensation.

[0151]

[0147] The PTHP configuration may be maintained and serviced efficiently. The PTHP configuration may comprise filters that may be quickly accessed via removal of the front panel. The PTHP configuration may comprise distinct modular subsystems dedicated to airflow, refrigeration, electrical, condensation management, and fresh air exchange. Critical error events may be logged in detail on the app and physically denoted by an error message on the PTHP configuration unit. If a component fails, the core module may be slid out, and the PTHP configuration contents may be serviced without the need to remove any sealing around the sleeve. Non-critical errors and maintenance suggestions may also be tracked in detail, allowing an operator to be notified preemptively when maintenance is suggested or when components begin to fail. The temperature and current sensors across all components inform refrigerant capacity, motor efficiency curves, and other values that are unknown in traditional systems without close analysis by an HVAC technician.

[0152]

[0148] An enclosure may not have the infrastructure for condensation management, and dripping presents a hazard to the structure and the people nearby. The PTHP configuration may comprise an atomization mechanism to fully dissipate condensation into the outdoor air without the need to drip condensate out of the PTHP configuration unit. An overflow drainage port may be available on the PTHP configuration unit for structures with condensate lines.

[0153]

[0149] There are an estimated 515,000 PTAC / PTHP units sold in the United States each year (per the DOE). Assuming ~4% of total U.S. PTAC / PTHP sales being in New York (consistent with NYC’s share of the hotel market and high-rise residential buildings that use PTACs), the top-down estimated demand in the New York State equates to around 22,500 units per year. Reportedly, 125,000 PTAC / PTHP units installed in New York State hotels (per NYSERDA). Adding the estimated 30% of the remaining market share of multifamily residential and other commercial segments, the total number of PTAC / PTHPs in New York state may be close to 180,000 units. Given the typical product lifespan of 10-15 years, New York state may see at least 12,000-18,000 replacements yearly and additional demand from new installations to bring the estimate close to 22,500 units annually.

[0154]

[0150] By offering easy-to-install, easy-to-maintain, and highly efficient PTHP units in the market, the PTHP configuration poses an opportunity to grow the market even further by providing a viable alternative for new construction projects to consider PTHP solutions compared to other options.

[0151] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.

Tests may be set to reflect regional winter profiles at key temperature points (e.g., 47°F, 35°F, 17°F, or as low as 5°F) while monitoring setting humidity (-60-80%) to induce defrost capacity7.

[0155] A coupled unit may achieve efficient cooling in hot, humid, summer conditions. In cooling mode, a coupled unit may deliver a COP of 3.0 up to 110°F. These metrics may be validated in a climate lab or verified through third-party testing with the WCEC and the Intertek Cortland, NY testing facility7.

[0160]

[0156] On high-humidity7days, a coupled unit may be set to modulate between cooling and dehumidification modes autonomously. By adjusting superheat, indoor coil temperature, and fan speed, a coupled unit may optimize across a gradient of sensible cooling and latent cooling. When spaces are unoccupied, a coupled unit may prioritize an initial dehumidification mode with a low7superheat and coil temperature significantly below7the room’s dew' point to increase humidity collection.

[0161]

[0157] When occupants are detected, or room temperature deviates too far from the set temperature, a coupled unit may behavior module may automatically reengage cooling mode.

[0162]

[0158] The ERV may provide 60 cubic CFM of fresh air exchange at a 90% energy recovery7efficiency.

[0163]

[0159] Multiple coupled units may be connected via common insulated water lines to form a central hydronic chain that is maintained at an optimally performant temperature of 20-30°C. Multiple coupled units can simultaneously add or subtract heat to and from the central line, which may increase overall building-wdde efficiency by up to 40% with minimal mechanical rework.

[0160] EXAMPLE 2: Distribution and Allocation of Thermal Energy

[0164]

[0161] To better understand the purpose of the hydronic network, a distribution and allocation of thermal energy through a network topology (FIG. 16) may be utilized.

[0165]

[0162] In a summer case (FIG. 16A), the desired temperature is cooling and the waste produced by the heat pump is heat. Neutral represents a middle temperature between Desired and Waste. As the outdoor ambient temperature generally trends towards waste, ambient is placed as a temperature state that sits between neutral and waste.

[0166]

[0163] A heat pumps may generate a temperature lift between the evaporator and condenser to be hotter than ambient in order to effectively remove heat into the outdoors. Thus, one sees a large compressor lift between the desired and waste states. Temperature lift and compressor load dramatically impacts the coefficient of performance (COP) of the system.

[0167]

[0164] The goal of the hydronics system (e.g., hydronic network topology) is to programmatically move heat around the building across multiple heat pumps to reduce the lift between desired and waste temperature across all heat pumps. Buildings often simultaneously have heating and cooling needs (water heaters in the summer, refrigerators in the winter) thus giving opportunity for heat pumps to utilize waste energy to reduce lift across the system. Without improving upon the physics of the vapor compression cycle and looking at exclusively the movement of energy7throughout the building, hydronics opens opportunities to better dissipate excess waste, reutilize useful waste, and reduce compressor lift on average across all systems to improve COP.

[0168]

[0165] It is only possible to transfer heat in one direction (low high entropy), thus it becomes progressively harder to push the system’s waste temperature left on the temperature range towards neutral as it requires higher quality desired temperature (FIG. 16B).

[0169]

[0166] Waste dissipation methods may be utilized to push the system’s waste further left on the temperature range, higher quality (low entropy) waste dissipation. In FIG. 16B, methods to the left of the temperature range are highest quality, and methods to the right have the least quality7. All methods on the left can also be utilized for state transitions on the right. In other words, simultaneous waste utilization or geothermal can help waste transition to ambient, but fan coils cannot transition neutral temperature waster to desired temperature.

[0170]

[0167] Waste Ambient is achieved by utilizing outdoor heat exchangers. Like traditional heat pump systems, fan coils are used to dissipate waste energy into ambient. Traditional air source heat pumps are often limited in efficiency by the size of the fan coil heat exchangers available in the outdoor unit. Hydronically networked coupled units disclosed herein avoid this constraint as the waste side heat exchange is water-based, meaning any number of fan coils may be placed in series as needed and allowable by the architecture.

[0168] Ambient — Neutral is a much more challenging transition as the outdoor air cannot be used to push the water temperature beyond ambient. External energy sources must be used to push ambient temperature water to neutral, thus these methods generally require batteries or other energy sources. Geothermal systems utilize the Earth’s thermal mass as a battery and often produce, less related to ambient temperature, a much more neutral temperature that is more favorable for heat pumps. If a geothermal system is available, the geothermal line may be interfaced with the waste line of the system in order to contribute beyond ambient. Similarly, other reservoirs such as large water tank thermal batteries and pools may be used to store energy. In the winter, the solar gain of roofs and walls are much warmer than the ambient air and a product line of heat capture systems may be introduced to push ambient water to a neutral state. Finally, the shared waste line that interfaces with an indoor unit allows for previously cooled / heated rooms to help dissipate waste. Similar to the outside units, which act as fan coils to the outdoor ambient air, indoor units may be utilized as fan coils to the tempered indoor air, which is often much closer to the desired temperature, to push ambient water further left. This process, or “Room Recovery,” is a higher-quality variant of the traditional fan coil system used for the ambient neutral transition.

[0171]

[0169] Neutral — > Desired is the final state transition that requires very high-quality energy and another heat pump achieve. Simultaneous heating and cooling scenarios may be utilized for this transition. If there is ever a heat pump that operates in reverse to the general needs of a system (water heater in summer, refrigerator in winter), the high-quality waste of that heat pump (which is high quality desired energy to the rest of the system) may be utilized to push neutral temperature water closer to desired temperature. In essence, reutilizing the waste energy of one heat pump for another. This is the most situational of all the waste dissipation methods as it requires another heat pump to concurrently run in an opposite direction but is the highest quality and quick method of generating desired temperature. In large buildings, these simultaneous scenarios become more common. Home appliance product lines that are hydronically networkable also create more opportunities for this type of simultaneous waste recovery7.
