Description

  The present invention relates to a system and method for sending air for heating or cooling from an air conditioner to various sections of a home or commercial building.

  Most conventional home heating and cooling systems have a centrally installed thermostat that controls the temperature of the entire house. Thermostats turn heating, ventilation, and air conditioning (HVAC) systems on and off for the entire home. The only way a resident can control the amount of HVAC air to each room is to manually open and close the ventilator throughout the house.

  Compartmented HVAC systems are commonly used in commercial buildings, and compartment systems are about to enter the home market. In a compartment system, each room, room group or compartment sensor monitors the temperature. Sensors can detect where and when air for heating or cooling is needed. The sensor sends information to the central controller, which activates the compartment system and adjusts a motorized regulating valve (damper) in the piping to deliver conditioned air only to the compartment that is needed. The partition system adapts to change conditions within an area without affecting other areas. For example, many two-story houses are partitioned by floor. As heat rises, the second floor is more demanding of cooling in the summer than the first floor and less demanding of heating in the winter. Unpartitioned systems cannot fully adjust for this seasonal change. However, compartmentalization can reduce the wide range of temperature changes between floors by supplying heating or cooling only to the space that needs it.

  The compartment system allows the occupant to decide which areas to heat or cool when and thus has more control over the indoor environment. Using the partition system, the resident can be programmed to operate in each specific partition as needed. For example, a resident can be set to not operate a bedroom during the day but to operate the kitchen and living room.

  A properly partitioned system can be up to 30% more efficient than an unpartitioned system. The compartment system supplies warm or cold air only to the necessary areas. In this way, useless energy for heating or cooling the unused space can be reduced.

  In addition, the use of a compartmentalized system can set up a smaller capacity device, sometimes without sacrificing comfort. This reduces wasted capacity and energy consumption.

Unfortunately, the equipment used in compartmental systems today is relatively expensive.
Furthermore, the installation of a partitioned HVAC system or refurbishment of an existing system exceeds the capabilities of most homeowners. Unless the homeowner is specially trained, configuring and installing the system requires hiring a specially trained professional HVAC technician. This makes it expensive to purchase and install a compartmental HVAC system. Even though the partitioning system is more efficient due to the high installation costs, the payback period for such a system can be many years. Such expenses have severely limited the growth of compartmentalization systems in the general home market.

  The disclosed system and method solves these and other problems by providing an ECRV (Electronically-Controlled Register Vent) that is easily installed by a homeowner or a general repairman. is there. ECRV is used to convert a non-partitioned HVAC system to a partitioned system. ECRV can be used in combination with a conventional partitioned HVAC system to provide additional control and additional partitions that were not provided by the conventional partitioned system. In an embodiment, the ECRV is configured to have a size and shape element that is compatible with a standard manually controlled ventilator. The ECRV can be attached to a conventional manually controlled ventilator without the use of tools.

  In an embodiment, the ECRV is a built-in compartment system unit that includes a ventilator, a power source, a thermostat, and a motor that opens and closes the ventilator. To create a compartmental HVAC system, the homeowner simply needs to remove the existing ventilator in one or more rooms and install a ventilator with ECRV. Residents can set the EVCR thermostat to control the temperature of the area or room in which the ECRV is equipped. In an embodiment, the ECRV includes a display device that displays the programmed set temperature. In an embodiment, the ECRV includes a display device that displays the current set temperature. In an embodiment, the ECRV includes a remote control interface that allows the occupant to control the ECRV by remote control. In an embodiment, the remote control includes a display that displays the programmed temperature and the current temperature. In the embodiment, the remote control indicates the power status of the ECRV.

  In an embodiment, the EVCR includes a pressure sensor that measures the pressure of the air in the ventilation line that supplies the air to the EVCR. In an embodiment, the EVCR opens the ventilator when the pressure of the air in the pipe exceeds a predetermined value. In the embodiment, the pressure sensor is configured as a differential pressure sensor that measures a pressure difference between air in the pipe and room air.

  In the embodiment, the ECRV is driven by an internal power source. The ECRV low power indicator notifies the homeowner when the power supply needs to be replaced. In an embodiment, one or more solar cells are provided and charge the power supply when there is light. In an embodiment, the ventilator includes a blower that draws additional air from the supply piping to make up for the smaller than normal vents or compartments that require additional heating or cooling air.

  In an embodiment, one or more ECRVs of a partition communicate with a partition thermostat. The compartment thermostat measures the temperature of the compartment for all ECRVs that control the compartment. In an embodiment, the ECRV and the compartment thermostat communicate using wireless communication, such as infrared communication, radio frequency communication, or ultrasonic communication. In the embodiment, the ECRV and the compartment thermostat communicate by direct wire communication. In an embodiment, the ECRV and the compartment thermostat communicate using a power line connection.

  In an embodiment, one or more thermostats communicate with the central controller.

  In an embodiment, the EVCR and / or compartment thermostat includes occupant sensors such as, for example, infrared sensors, motion sensors, and ultrasonic sensors. The occupant can program the EVCR or compartment thermostat so that the compartment is at a different temperature when there are people in the compartment and when the compartment is empty. In an embodiment, the compartment may be at a different temperature based on whether there is a resident in the compartment, the time of day, the duration of the year, the type of room (eg, bedroom, kitchen, etc.), etc. EVCR or compartment thermostat can be programmed. In an embodiment, various EVCR groups and / or compartment thermostats in a composite compartment (eg, a compartment group such as an entire house, an entire floor, a full wing, etc.) communicate with each other to set the set temperature to be empty or populated. Change according to whether there is a person.

  In an embodiment, a resident of a house can prioritize based on whether there is a resident in the section, a time of day, a period of one year, or the like. For example, if a section is a bedroom and another section corresponds to the living room, the section can be given a relatively low priority during the day and a relatively high priority at night. As a second example, when a parcel is on the first floor and another parcel corresponds to the second floor, another parcel is given a higher priority in the summer (because the upper floor is difficult to cool) and lower in winter Priority can be given (because it is difficult to heat the lower floors). In an embodiment, the occupant can specify an important priority for each section.

  FIG. 1 shows a partitioned heating and cooling house 100. Within the house 100, the HVAC system supplies heating and cooling air to the piping system. Sensors 101 to 105 monitor the temperature of each area (section) of the house. A partition may be a room, a floor, or a group of rooms. Sensors 101-105 detect where and when air for heating or cooling is needed. Information from sensors 101-105 is used to control an actuator that regulates the air flow to the various compartments. The partition system is designed to change conditions within an area without affecting other areas. For example, many two-story houses are partitioned by floor. As the heat rises, the second floor requires more cooling than the first floor in summer and more heating in the winter. Unpartitioned systems cannot fully adjust for this seasonal change. However, partitioning can reduce large temperature changes between floors by providing heating or cooling only to the space that needs it.

  FIG. 2 shows an example of a conventional manually controlled ventilator 200. Ventilator 200 includes one or more vanes 201 that can be opened and closed to regulate the amount of air flowing through the ventilator. A diverter (diverter) 202 directs the air in one or more desired directions. The blade 201 is usually provided in a mechanical mechanism, and the resident can operate the blade 201 to control the amount of air flowing out of the ventilation device 200. In some ventilators, the shunt 202 is fixed. In some ventilators, the shunt 202 is movable and the occupant has some control over the direction of air flowing out of the vent. Ventilation devices, such as the ventilation device 200, are found in many homes with a central HVAC that supplies heating and cooling air. In general, relatively small rooms such as bedrooms and bathrooms are equipped with one or two ventilators of different sizes. Large rooms such as living rooms and family rooms may have more than one such ventilation device. A resident in the home can manually adjust the blade 201 to control the flow of air passing through each ventilation device. Such adjustment is usually not particularly difficult when the ventilator is located at a relatively low level on the floor or wall (unless the mechanism controlling the vanes 201 is bent or rusted). However, when the ventilator 200 is placed on a wall at a high and inaccessible position, the adjustment of the vanes 201 can be very difficult.

  FIG. 3 shows an embodiment of an electrically controlled ventilator (ECRV) 300. The ECRV 300 can be used to implement a compartmentalized heating and cooling system. The ECRV 300 can also be used as a ventilator that is remotely controlled where the vent is located at a high position on the wall and cannot be easily reached. The ECRV 300 is configured to substitute for the vent 200. This greatly simplifies the task of renovating the house by replacing one or more ventilators 200 with ECRV 300. In one embodiment shown in FIG. 3, ECRV 300 is configured to fit a piping opening that is approximately the same size as conventional ventilator 200.

  In an embodiment, the ECRV 300 is configured to fit the piping opening used in the conventional ventilator 200. In one embodiment, the ECRV 300 is configured to fit the piping opening used in the conventional ventilator 200, so that the ventilator 200 is left in place. The control panel 301 includes one or more image display devices, and selectively includes a plurality of user control units. The housing 302 is provided to accommodate an operating device for controlling the blades 201. In the embodiment, the housing 302 can also be used to accommodate electronic devices, batteries, and the like.

  4 is a block diagram of one embodiment of the ECRV 300 shown in FIGS. 3A and 3B, and the ECRV built-in ECRV 400 shown in FIG. In the ECRV 400, a temperature sensor 406 and a temperature sensor 416 are provided in the controller 401. Controller 401 controls actuator system 409. In an embodiment, actuator 409 provides position feedback to controller 401. In an embodiment, the controller 401 reports the position of the actuator to the central control system and / or the compartment thermostat. Actuator system 409 provides mechanical movement to control the flow of air through the vent. In an embodiment, the actuator system 409 includes an actuator provided in the vent 201 or other air flow device to control the amount of air passing through the ECRV 400 (eg, the amount of air flowing from the piping to the room). In an embodiment, the actuator system includes an actuator attached to one or more flow dividers 202 to control the direction of air flow. The controller 401 also controls the image display device 403 and the optional blower 402. A user input device 408 is provided so that the user can set the desired room temperature. Optionally, a sensor 407 is provided in the controller 401. In an embodiment, sensor 407 includes an air pressure and / or air flow sensor. In one embodiment, sensor 407 includes a humidity sensor.

  The power supply 404 supplies necessary power to the controller 401, the blower 402, the display device 403, the temperature sensors 406 and 416, the sensor 407, and the user input device 408. In an embodiment, controller 401 controls the amount of power provided to blower 402, display device 403, sensor 406, sensor 416, sensor 407 and user input device 408. In an embodiment, an optional auxiliary power source 405 is also provided to provide additional power. The auxiliary power source is a power supply supplement source, such as a battery, a solar cell, an airflow (eg, wind) generator, a blower 402 operating as a generator, a nuclear power generator, a fuel cell, a thermocouple, and the like.

  In the embodiment, the power source 404 is based on a non-rechargeable battery, and the auxiliary power source 405 includes a solar battery and a rechargeable battery. The controller 401 draws power from the auxiliary power source when possible to conserve power in the power source 404. If the auxiliary power source 405 cannot supply sufficient power, the controller 401 also draws power from the power source 404.

  In another embodiment, power source 404 is configured as a rechargeable battery and auxiliary power source 405 is configured as a solar cell that charges power source 404.

  In an embodiment, display device 403 includes an indicator that blinks when available power from power sources 404 and / or 405 drops below a threshold (eg, a blinking LED or LCD).

  A home resident uses the user input device 408 to set the desired temperature near the ECRV 400. Display device 403 displays the set point temperature. In the embodiment, the display device 403 also displays the current (in progress) room temperature. The temperature sensor 406 measures the room temperature, and the temperature sensor 416 measures the temperature in the pipe. When the room temperature is equal to or higher than the set point temperature and the temperature of the air in the pipe is equal to or lower than the room temperature, the controller 401 activates the operating device 409 and opens the vent. When the room temperature is equal to or lower than the set point temperature and the temperature of the air in the pipe is equal to or higher than the room temperature, the controller 401 activates the operating device 409 and opens the vent. In other cases, the controller 401 activates the actuator 409 to close the vent. In other words, when the room temperature is above or below the set point temperature and the temperature of the air in the pipe approaches the set point temperature, the controller 401 opens the vent and allows air to enter the room. On the other hand, when the room temperature is above or below the set point temperature and the temperature of the piping air does not bring the room temperature close to the set point temperature, the controller 401 closes the vent.

  In an embodiment, the controller 401 is configured to provide several degrees of hysteresis around the set point temperature (often referred to as a thermostat deadband), thereby causing excessive opening and closing of the vents. Prevent waste of power.

  In an embodiment, the controller 401 activates the blower 402 to draw additional air from the piping. In an embodiment, the blower 402 is used when the room temperature is relatively far from the set point temperature, accelerating the movement of the room temperature closer to the set point temperature. In an embodiment, blower 402 is used when room temperature changes relatively slowly in response to an open vent. In an embodiment, the blower 402 is used when the room temperature is moving away from the set point temperature and the vent is open. The controller 401 does not activate or operate the blower 402 unless there is sufficient power available for the power supplies 404 and 405. In the embodiment, the controller 401 measures the power levels of the power supplies 404 and 405 periodically (continuously) before starting the blower 402 and when the blower is started.

  In an embodiment, the controller 401 also does not activate the blower 402 unless it senses the flow of air in the pipe (indicating that the HVAC air blower is sending air into the pipe). In an embodiment, sensor 407 includes an air flow sensor. In an embodiment, the blower 402 rotates in response to the air flow from the piping, and the controller 401 causes the blower 402 to operate as an air flow sensor by measuring (or detecting) the voltage generated by operating the blower as a generator. Use as In the embodiment, the controller 401 periodically stops the blower and checks the air flow from the pipe.

  In an embodiment, sensor 406 includes a pressure sensor configured to measure air pressure in the piping. In an embodiment, sensor 406 is a differential pressure sensor configured to measure the pressure difference between the air in the piping and the air outside the ECRV (eg, room air). Too high pressure in the pipe indicates too many closed vents (thus creating too much back pressure in the pipe and reducing air flow in the HVAC system). . In an embodiment, the controller 401 opens the vent when it detects excessive pressure.

  The controller 401 conserves power by powering down unused ECRV 400 elements. The controller 401 monitors the power available from the power sources 404 and 405. When the available power falls below the low power threshold, the actuator 409 is controlled to the open position, the display device 403 is used to activate the visual indicator, and the low power mode is entered. In the low power mode, the controller 401 monitors the power sources 404, 405, but the controller does not provide partition control functions (eg, the controller does not close the actuator 409). When the controller detects that sufficient power has been restored again (eg, by charging one or more of the power supplies 404, 405), the controller 401 resumes normal operation.

  FIG. 5 is a block diagram of a built-in ECRV 500 with a remote control interface. The ECRV 500 includes power supplies 404 and 405, a controller 401, a blower 402, a display device 403, temperature sensors 406 and 416, a sensor 407, and a user input device 408. The remote control interface 501 is provided in the controller 401, and the controller 401 can communicate with the remote control 502. The controller 502 sends a wireless signal to the remote control interface 501 using wireless communication such as infrared communication, ultrasonic communication and / or radio frequency communication.

  In the embodiment, the communication is one way from the remote control 502 to the controller 401. The remote control 502 can be used to set a temperature set point to indicate to the controller 401 to open and close (partially or completely) the vent and / or to activate the blower. In the embodiment, the communication between the remote control 502 and the controller 401 is bidirectional communication. Using bi-directional communication, the controller 401 can send information for the display device on the remote control 502, such as the current room temperature, the power status of the power supplies 404, 405, diagnostic information, and the like.

  ECRV 400 described in connection with FIG. 4 and ECRV 500 described in connection with FIG. 5 are configured to operate as a self-contained device in a relatively stand-alone mode. When two ECRVs 400, 500 are placed in the same room or compartment, the ECRVs 400, 500 do not necessarily operate in harmony. FIG. 6 is a block diagram of a partial (local) controlled compartment heating and cooling system 600 in which a compartment thermostat 601 monitors the temperature of the compartment 608. The ECRVs 602 and 603 are configured to communicate with the compartment thermostat 601. In the example, ECRVs 602-603 are shown, for example, in connection with FIG. In the embodiment, the partition thermostat 601 sends a control command to the ECRVs 602 to 603 to activate the opening and closing of the ECRVs 602 to 603. In the embodiment, the compartment thermostat 601 sends temperature information to the ECRVs 602 to 603, and the ECRV 602 to 603 determines opening or closing based on the temperature information received from the compartment thermostat 601. In an embodiment, the compartment thermostat 601 sends information regarding the current compartment temperature and set point temperature to the ECRVs 602-603.

  In an embodiment, ECRV 602 communicates with ECRV 603 to improve the structural stability of system 600 communications. Thus, for example, when the ECRV 602 cannot communicate with the partition thermostat 601 but can communicate with the ECRV 603, the ECRV 603 acts as a router between the ECRV 602 and the partition thermostat 601. In an embodiment, ECRV 602 and ECRV 603 communicate to arbitrate opening and closing of their respective vents.

  The system 600 shown in FIG. 6 provides partial (local) control of the partition 608. Any number of independent partitions can be controlled by replicating the system 600. FIG. 7A is a block diagram of a centrally controlled compartment heating and cooling system in which the central control system 710 communicates with one or more compartment thermostats 707, 708 and one or more ECRVs 702-705. In system 700, compartment thermostat 707 measures the temperature of compartment 711 and ECRVs 702, 703 regulate the air to compartment 711. The compartment thermostat 708 measures the temperature of the compartment 712 and the ECRVs 704, 705 regulate the air to the compartment 712. Central thermostat 720 controls HVAC system 720.

  FIG. 7B is a block diagram of a central control zone heating and cooling system 750 similar to the system 700 shown in FIG. 7A. In FIG. 7B, central system 710 communicates with compartment thermostats 707, 708, compartment thermostat 707 communicates with ECRVs 702, 703, compartment thermostat 708 communicates with ECRVs 704, 705, and central system 710 communicates with ECRVs 706, 707. In system 750, ECRVs 702-705 are in the compartments associated with compartment thermostats 707, 708, respectively, and compartment thermostats 707, 708 control the respective ECRVs 702-705. The ECRVs 706, 707 are independent of any particular compartment thermostat and are controlled directly by the central system 710. One skilled in the art will appreciate that the communication topology shown in FIG. 7B can also be used in the context of the systems shown in FIGS.

  Although central system 710 controls and coordinates the operation of partitions 711 and 712, system 710 does not control HVAC system 721. In an embodiment, central system 710 operates independently of thermostat 720. In an embodiment, a thermostat 720 is included in the central system 710, which detects when the thermostat requires heating, cooling or blowing.

  Central system 710 coordinates and prioritizes the operation of ECRVs 702-705. In the embodiment, the resident of the house assigns priorities for the sections 711 and 712 based on whether there are residents in the sections, the time of the day, the period of one year, or the like. In this way, for example, when the section 711 is a bedroom and the section 712 corresponds to the living room, the section 711 can be given a relatively low priority during the day and a relatively high priority at night. As a second example, when parcel 711 corresponds to the first floor and parcel 712 corresponds to the second floor, parcel 712 is given a relatively high priority in the summer (because the upper floor is difficult to cool) and lower in winter. (Because it is difficult to heat the lower floors). In an embodiment, the resident can designate a priority with importance for each section.

  Closing too many vents at a time often causes problems with the central HVAC system. This is because the air flow through the HVAC system is reduced and efficiency is reduced. The central system 710 can adjust how many vents are closed (or partially closed), and this allows enough vents to be opened to maintain proper airflow through the system. Like that. The central system 710 thus provides an air flow through the house so that the upper floor receives a relatively large amount of cooled air and the lower floor receives a relatively large amount of heated air. It can also be managed.

  FIG. 8 is a block diagram of a centrally controlled compartmental cooling and heating system 800. System 800 is similar to system 700 and includes compartment thermostats 707, 708 and ECRVs 702-705 that monitor compartments 711, 712, respectively. The compartment thermostats 708, 708 and / or ECRVs 702-705 communicate with the central controller 810. In system 800, thermostat 720 is provided in central system 810, and central system 810 directly controls HVAC system 721.

  The controller 810 provides similar functions as the controller 710. However, the controller 810 is more preferred because it also controls the operation of the HVAC system 721 and can require the heating and cooling necessary to maintain the desired temperature in the compartments 711, 712. The central thermostat 720 may not be present once the compartment thermostat and ECRV are set up in all or almost all of the house.

  In some situations, the controller 810 activates the HVAC blower (without heating and cooling) and does not require heating or cooling according to the return air flow path in the house, and from the too hot to the too cold ( Or vice versa). The controller 810 can provide efficient use of the HVAC system by requesting heating and cooling as needed to provide the appropriate amount of heating and cooling to the appropriate compartment. If the HVAC system 721 provides multiple modes of operation (eg, high speed, low speed, etc.), the controller 810 can operate the HVAC system 721 in the most efficient mode that provides the amount of heating or cooling required.

  FIG. 9 is a block diagram of a centrally controlled section cooling and heating system 900 for efficiency monitoring. System 900 is similar to system 800. In the system 900, the controller 810 is replaced with an efficiency monitoring controller 910 that is configured to receive sensor data (eg, system operating temperature, etc.) from the HVAC system 721 and monitor the efficiency of the HVAC system 721.

  FIG. 10 is a block diagram of the ECRV 1000 for use in connection with the system shown in FIGS. The ECRV 1000 includes power supplies 404, 405, a controller 401, a blower 402, a display device 403, and optionally a temperature sensor 416, a sensor 407, and a user input device 408. A communication system 1081 is provided in the controller 401. A remote control interface 501 is provided in the controller 401, and the controller 401 can communicate with the remote control 502. The controller 502 sends a wireless signal to the remote control interface 501 using wireless communication such as infrared communication, ultrasonic communication and / or radio frequency communication.

  The communication system 1081 is configured to communicate with a compartment thermostat and optionally a central controller 710, 810, 910. In an embodiment, the communication system 1081 is configured to communicate using wireless communication such as infrared communication, wireless communication, or ultrasonic communication.

  FIG. 11 is a block diagram of a basic compartment thermostat 1100 for use in connection with the system shown in FIGS. In the compartment thermostat 1100, a temperature sensor 1102 is provided in the controller 1101. A user input control 1103 is also provided on the controller 1101 to allow the user to specify a set point temperature. An image display device 1110 is provided in the controller 1101. The controller 1101 uses the image display device 1110 to display the current temperature, set point temperature, power supply status, and the like. A communication system 1181 is also provided in the controller 1101. A power source 404 and optionally a power source 405 are provided to supply power to the controller 1100, the control 1101, the sensor 1103, the communication system 1181, and the image display device 1110.

  In systems where a central controller 710, 810, 910 is used, the communication method used by the partition thermostat 1100 to communicate with the ECRV 1000 is the method used by the thermostat 1100 to communicate with the central controller 710, 810, 910. Need not be the same method. Thus, in the exemplary embodiment, communication system 1181 includes one type of communication with a central controller (eg, infrared, wireless, ultrasound) and another type of communication with ECRV 1000.

  In an embodiment, the compartment thermostat is powered from a battery. In an embodiment, the compartment thermostat is configured as a standard optical switch and receives power from the optical switch circuit.

  FIG. 12 is a block diagram of a compartment thermostat 1200 with a remote control for use in connection with the system shown in FIGS. The thermostat 1200 is similar to the thermostat 1100 and includes a temperature sensor 1102, an input control 1103, an image display device 1110, a communication system 1181 and power supplies 404 and 405. In the compartment thermostat 1200, a remote control interface 501 is provided in the controller 1101.

  In the embodiment, a resident sensor 1201 is provided in the controller 1101. For example, a resident sensor 1201 such as an infrared sensor, a motion sensor, or an ultrasonic sensor detects that a resident is in the section. The resident can program the compartment thermostat 1201 to bring the compartment to different temperatures when the resident is in the compartment and when it is empty. In an embodiment, a resident may program a compartment thermostat 1201 depending on the time of day, period of one year, the type of room (eg, bedroom, kitchen, etc.), and whether the room is resident or empty. The compartments can be at different temperatures. In an embodiment, the group of compartments are combined into a composite compartment (eg, a group such as an entire house, an entire floor, a full wing, etc.), and the central system 710, 810, 910 depending on whether the composite compartment is empty or resident. Changes the temperature settings of the various compartments.

  FIG. 13 shows one embodiment of a central monitoring station console 1300 for accessing the functions represented by blocks 710, 810, 910 in FIGS. Station 1300 includes a display device 1301 and a keypad 1302. The resident can use the central system 1300 and / or the compartment thermostat to specify compartment temperature settings, priorities, and thermostat deadband. In the embodiment, the console 1300 is realized as a hardware device. In the embodiment, the console 1300 is realized by software as a computer display, for example, on a personal computer.

  FIG. 14 is a flowchart illustrating one embodiment of an instruction loop process 1400 for an ECRV or partition thermostat. Process 1400 begins at power on block 1401. After powering up, the process proceeds to initialization block 1402. After initialization, the process proceeds to “Listen” block 1403 where the ECRV or partition thermostat listens for one or more instructions. If decision block 1404 determines that an instruction has been received, the process proceeds to “execute instruction” block 1405. If not, the process returns to listening block 1403.

  For ECRV, the command group opens the vent, closes the vent, opens the vent to the specified partially open position, reports sensor data (eg, airflow, temperature, etc.), status (eg, Reporting battery status, vent location, etc.). For a compartment thermostat, instructions can include reporting temperature sensor data, reporting rate of temperature change, reporting setpoints, reporting status, and so on. In systems where the central system communicates with the ECRV via a compartment thermostat, the commands include ECRV report number, ECRV data (eg temperature, airflow, etc.) report, ECRV vent position report, ECRV vent position change, etc. Can be included.

  In an embodiment, the listening block 1403 consumes relatively little power, so the ECRV or compartment thermostat can stay in the loop corresponding to the listening block 1403 and the conditional branch 1404 for a long time.

  The listening block 1403 can be implemented using relatively little power, while the sleep block can be implemented with even less power. FIG. 15 is a flowchart illustrating one embodiment of a command and sensor data loop process 1500 for an ECRV or partition thermostat. Process 1500 begins at power up block 1501. After powering up, the process proceeds to initialization block 1502. After initialization, the process proceeds to a “sleep” block 1503 where the ECRV or partition thermostat sleeps for a specified period. After the sleep period has elapsed, the process proceeds to awake block 1504 and then proceeds to decision 1505. If a failure is detected at decision block 1505, a failure transmission block 1506 is executed. The process then proceeds to sensor block 1507 where a sensor reading is taken.

If a failure is detected, the decision block advances the process to send failure block 1605, otherwise the process advances to sensor block 1606 where a sensor reading is obtained. If the value of the data from one or more sensors is evaluated and the sensor data is outside the specified range, or if a timeout occurs, the process proceeds to data transmission block 1608, otherwise the process proceeds to sleep block 1609. move on. After transmitting in the fault transmit block 1605 or sensor data transmit block 1608, the process proceeds to a listen block 1610 where the ECRV or partition thermostat listens for instructions. If an instruction is received, the process then proceeds to instruction execution block 1612, otherwise the process proceeds to sleep block 1609. After executing the execute instruction block 1612, the process sends an “instruction complete message” and returns to the listen block 1610.

  The process flows shown in FIGS. 14-16 illustrate various levels of interaction between devices and various levels of power protection in an ECRV and / or compartment thermostat. Those skilled in the art will receive ECRV and partition thermostats that receive sensor data and user input, report sensor data and user input to other devices in the partition control system, and respond to commands from other devices in the partition control system. You will understand that it is configured to. In this way, the process flows shown in FIGS. 14-16 are provided for purposes of illustration, not limitation. Other data reporting and instruction process loops will be apparent to those skilled in the art using the ones disclosed herein.

  In an embodiment, the ECRV and / or compartment thermostat “sleeps” between sensor readings. In the exemplary embodiment, central system 710 provides a “wake-up” signal. When the ECRV or compartment thermostat receives the wake-up signal, it takes one or more sensor readings, encodes it into a digital signal, and transmits the sensor data along with the identification code.

  In an embodiment, the ECRV is configured to receive instructions from the central system in both directions. Thus, for example, the central system commands the ECRV to perform additional measurements such as: go to standby mode, wake up, report battery status, change wake-up period, perform self-diagnosis , And reporting the results.

  In an embodiment, the ECRV has two wake-up modes, the first wake-up mode is for performing measurements (and reports such measurements if deemed necessary), and the second wake-up mode is the central system. This is to listen to the command from. The two wake-up modes or combinations thereof can occur at different intervals.

  In an embodiment, the ECRV communicates with the compartment thermostat and / or the central system using spread spectrum technology. In an embodiment, ECRV uses a frequency hopping spread spectrum. In the embodiment, each ECRV has an identification code (ID), and the ECRV attaches the ID to a communication packet to be transmitted. In an embodiment, when receiving wireless data, each ECRV ignores data addressed to other ECRVs.

  In an embodiment, ECRV comprises bi-directional communication and is configured to receive data and / or instructions from a central system. In this way, for example, the central system commands the ECRV to make additional measurements, go to standby mode, wake up, report battery status, change the wake-up period, perform self-diagnosis, and return results Reporting, etc. In an embodiment, the ECRV periodically reports its general health and status (eg, self-diagnosis results, battery health, etc.).

  In an embodiment, ECRV communicates with the central system using spread spectrum technology. In an embodiment, ECRV uses a frequency hopping spread spectrum. In an embodiment, the ECRV has one address or identification code (ID) that distinguishes the ECRV from other ECRVs. The ECRV attaches its ID to the communication packet to be transmitted, so that the transmission from the ECRV is identified by the central system. The central system appends the ECRV ID to the data and / or instructions sent to the ECRV. In an embodiment, the ECRV ignores data and / or instructions addressed to other ECRVs.

  In an embodiment, the ECRV, partition thermostat, central system, etc. communicate in the 900 MHz frequency band. This frequency band transmits relatively well through walls and other obstacles normally found in and around building structures. In an embodiment, the ECRV and compartment thermostat communicate with the central system in the frequency band above and / or below the 900 MHz frequency band. In an embodiment, the ECRV and partition thermostat listens to the radio frequency channel before transmitting on that channel or before starting transmission. When a channel is in use (eg, by other central systems, wireless telephones, etc.), the ECRV and / or partition thermostat changes to a different channel. In an embodiment, the sensor, the central system listens to the radio frequency channel to avoid interference and uses an algorithm to select the next channel for transmission that avoids interference to adjust frequency hopping. In an embodiment, the ECRV and / or partition thermostat transmits data until it receives an acknowledgment that it has received a message from the central system.

  Frequency hopping radio systems provide the advantage of preventing interference signals from others and preventing collisions. Furthermore, the advantage of adjusting power is given to systems that do not transmit continuously at one frequency. Channel hopping transmission changes frequency after a continuous transmission period or when it encounters interference. These systems can have greater transmit power and relax in-band spurious limitations.

  In an embodiment, the controller 401 reads the sensors 406, 407, 416 at regular time intervals. In an embodiment, the controller 401 reads the sensors 406, 407, 416 at random time intervals. In an embodiment, controller 401 reads sensors 406, 407, 416 in response to an alarm signal from the central system. In an embodiment, the controller 401 sleeps between sensor readings.

  In an embodiment, the ECRV continues to send sensor data until it receives a handshake type receipt notification. In this way, instead of sleeping, ECRV retransmits and receives the data when it does not receive a post command or receipt notification after transmission (eg, command blocks 1510, 1405, 1612 and / or transmit blocks 1605, 1608). Wait for notification. The ECRV continues to transmit data until a receipt notification is received and waits for the receipt notification. In an embodiment, once the ECRV receives an acknowledgment from the partition thermostat, it is the partition thermostat's responsibility to ensure that data is transferred to the central system. The bi-directional communication capabilities of the ECRV and the compartment thermostat allow the central system to control the operation of the ECRV and / or the compartment thermostat, providing the possibility for a robust handshake type communication between the ECRV, the compartment thermostat and the central system.

  In one embodiment of the system 600 shown in FIG. 6, the ECRVs 602, 603 send piping temperature data to the compartment thermostat 601. Compartment thermostat 601 compares the piping temperature to room temperature and set point temperature and determines whether to open ECRV 602,603. The compartment thermostat 601 then sends commands to the ECRVs 602, 603 to open and close the vents. In the embodiment, the compartment thermostat 601 displays the position of the vent on the image display device 1110.

  In one embodiment of the system 600 shown in FIG. 6, the compartment thermostat 601 sends setpoint temperature information and current room temperature information to the ECRVs 602,603. ECRV 602, 603 compares the piping temperature to room temperature and set point temperature to determine whether to open the vent. In an embodiment, the ECRVs 602, 603 send information about the location of the vents (eg, open, closed, partially open, etc.) to the compartment thermostat 601.

  In systems 700, 750, 800, 900 (centralized system), compartment thermostats 707, 708 send room temperature and set point temperature information to the central system. In an embodiment, the compartment thermostats 707, 708 also send temperature gradient (eg, temperature rise or fall rate) information to the central system. In systems where the thermostat 720 is provided in the central system or where the central system controls the HVAC system, the central system knows whether the HVAC system is supplying heating or cooling. Otherwise, the central system uses the piping temperature information provided by ECRVs 702-705 to determine whether the HVAC system is supplying heating or cooling. In an embodiment, the ECRV sends pipe temperature information to the central system. In an embodiment, the central system queries ECRV by sending an instruction to one or more ECRVs 702-705 instructing ECRV to send its piping temperature.

  The central system determines how much to open and close the ECRVs 702-705 according to the available heating and cooling capabilities of the HVAC system, compartment priority, and the difference between the desired and current temperature of each compartment. In an embodiment, a resident uses a compartment thermostat 707 to set a setpoint temperature and priority for the compartment 711 and a compartment thermostat 708 to set a setpoint temperature and priority for the compartment 712, etc. In an embodiment, the resident uses the central system console 1300 to set the set point temperature and priority for each compartment so that the compartment thermostat overrides the central setting (continuously or temporarily). Set. In the example, the central console 1300 displays the current temperature, set point temperature, temperature gradient, and priority of each section.

  In an embodiment, the central system distributes HVAC air for each compartment according to the priority of each compartment and the temperature of the compartment relative to the set point temperature of each compartment. Thus, for example, in one embodiment, a central system that has not reached the setpoint temperature and has a relatively high priority, has a lower priority and a temperature that is relatively close to the setpoint temperature. Supply more HVAC air than compartments. In an embodiment, the central system prevents closing or partially closing too many pipes to prevent the air flow in the pipes from being reduced below a desired minimum.

  In an embodiment, the central system monitors the rate of temperature rise (or decline) in each compartment, sends a command to adjust the amount by which each ECRV 702-705 is opened, brings the higher priority compartment to the desired temperature, and lower priority. Make sure the rank section does not stay too far from the set point temperature.

  In an embodiment, the central system uses a predictive model to calculate the amount of opening of the vents for each ECRV 702-705, reducing the number of vent openings and reducing the power consumption of the actuator 409. In an embodiment, the central system uses a neural network to calculate the desired opening for each vent in ECRV 702-705. In an embodiment, various operating parameters, such as central HVAC capacity, house volume, etc., are programmed into the central system and used to calculate vent opening and closing. In an embodiment, the central system is adaptive and configured to learn the operating characteristics of the HVAC system and the ability of the HVAC system to control the temperature of the various compartments when the ECRVs 702-705 are opened and closed. In an adaptive learning system, when the central system controls the ECRV to achieve the desired temperature over a given period, the central system will determine how much ECRV to achieve the desired level of heating and cooling for each compartment. Learn what needs to be opened. Using such an adaptive central system is advantageous because the installer does not have to program the operating parameters of the HVAC into the central system. In an embodiment, the central system, for example, appears to be operating abnormally without changing the temperature of one or more compartments as expected (eg, the HVAC system is not operating properly, or windows or doors are open). Alert when it looks like.

  In an embodiment, the adaptation and learning ability of the central system can be achieved through various adaptation results based on whether the HVAC is heating, cooling, outdoor temperature, compartment set point temperature, or priority change (e.g. Use different coefficients). Thus, in an embodiment, the central system uses the first adaptive coefficient group when the HVAC is cooling and uses the second adaptive coefficient group when the HVAC is heating. In an embodiment, the adaptation is based on a prediction model. In an embodiment, the adaptation is based on a neural network.

  FIG. 17 shows an ECRV 1700 configured to be used in conjunction with a conventional T-bar ceiling system found in many commercial buildings. In the ECRV 1700, an actuator 1701 (as one example of the actuator 409) is provided in the damper 1702. The regulating valve (damper) 1702 is provided in a diffuser 1703 configured to be attached to a conventional T-bar ceiling system. The ECRV 1700 is connected to the compartment thermostat or central system by wireless or wired communication.

  In an embodiment, sensor 407 in ECRV includes an air flow and / or air velocity sensor. Data from sensor 407 is sent to the central system by ECRV. The central system uses airflow and / or air velocity measurements to determine the relative amount of air passing through each ECRV. In this way, for example, using airflow / air velocity measurements, the central system is located farther from the blower than smaller ECRVs and ECRVs located near the blower (closer ECRV is Can be adapted to low airflows (which tend to receive more airflow).

  In an embodiment, sensor 407 includes a humidity sensor. In an embodiment, the compartment thermostat 1100 includes a compartment humidity sensor mounted on the controller 1101. A compartment control system (eg, central system, compartment thermostat, and / or ECRV) uses the humidity information from the humidity sensor to calculate a comfort value for the compartment and adjust the temperature setpoint according to the comfort value. Thus, for example, in an embodiment, during the summer cooling season, the compartment control system lowers the compartment temperature set point during periods of relatively high humidity and the compartment temperature setting during periods of relatively low humidity. Increase the point. In an embodiment, using a compartment thermostat, the occupant can specify comfort settings based on temperature and humidity. In an embodiment, the compartment control system controls the HVAC system to add or remove moisture from the heated / cooled air.

  FIG. 18 shows a ventilator 1800 configured to control air flow using a scrolling curtain 1801 as an alternative to the vanes shown in FIGS. An actuator 1802 (one embodiment of the actuator 409) is provided on the curtain 1801 to move the curtain 1801 across the ventilator and control the size of the airflow opening of the ventilator. In the embodiment, the curtain 1801 is guided by a track 1803 and held in a predetermined position.

  In the embodiment, the actuator 1802 is a rotary actuator, and a scrolling (winding) curtain 1801 is wound around the actuator to open the ventilation device 1800. When the actuating device 1802 rotates and unwinds the curtain 1801, the curtain is sufficiently hard and is pushed by the actuating device 1802 to the opening of the vent.

  FIG. 19 is a block diagram of a control algorithm 1900 for controlling the ventilation device. For purposes of illustration and not limitation, the algorithm 1900 is described as being executed on a central system. However, those skilled in the art will appreciate that algorithm 1900 can be implemented in a central system, compartment thermostat, ECRV, or that algorithm 1900 can be distributed in the central system, compartment thermostat, and ECRV. In algorithm 1900, set point temperatures from one or more compartment thermostats are provided to calculation block 1902 at block 1901 of algorithm 1900. The calculation block 1902 determines the ventilation device settings (e.g., how much each ventilation device is in accordance with the division temperature, division priority, available heating and cooling air, previous ventilation device settings, etc. as described above. Open / close). In an embodiment, block 1902 uses a prediction model as described above. In an embodiment, block 1902 calculates the vent settings for each compartment independently (eg, without considering interaction between compartments). In an embodiment, block 1902 calculates vent settings for each compartment in a combined compartment scheme that includes interactions between compartments. In an embodiment, the calculation block 1902 takes into account the current opening of the vent and calculates the new opening of the vent in a manner configured to minimize power consumption due to opening and closing of the vent.

  The vent settings from block 1902 are provided to each vent actuator in block 1903, where the vents are moved to the desired new opening position (and optionally one or more blowers 402 are activated). And additional air is drawn from the desired piping). After setting the new vent opening at block 1903, the process proceeds to block 1904 where the new compartment temperature is obtained from the compartment thermostat (the new compartment temperature corresponds to the new vent opening setup at block 1903). To do). The new compartment temperature is provided to the adaptation input of block 1902 and used to adapt to the prediction model used in block 1902. The new compartment temperature is also provided to the temperature input of block 1902 and is used to calculate a new vent setting.

  As described above, in one embodiment, the algorithm used in the calculation block 1902 may set each compartment to a desired temperature based on the current temperature, available heating and cooling, the amount of air available through each ECRV, etc. Configured to predict the opening of the ECRV required to The calculation block attempts to calculate the required ECRV opening over a relatively long period of time in order to reduce power consumption due to unnecessary opening and closing of the vents using a predictive model. In an embodiment, the ECRV is powered from the battery, and thus restraining the movement of the vent extends the battery life. In an embodiment, block 1902 uses a prediction model that learns the characteristics of the HVAC system and various partitions, and thus the prediction of the model tends to improve over time.

  In an embodiment, the compartment thermostat reports the compartment temperature to the central system and / or ECRV at regular intervals. In an embodiment, the compartment thermostat reports the compartment temperature to the central system and / or ECRV after the compartment thermostat temperature is changed by a specific value specified by the threshold. In one embodiment, the compartment thermostat reports the compartment temperature to the central system and / or ECRV in response to a request command from the central system or ECRV.

  In an embodiment, the compartment thermostat reports the set point temperature and compartment priority values to the central system or ECRV whenever a resident uses the user controls 1102 to change the set point temperature or compartment priority. In an embodiment, the compartment thermostat reports the set point temperature and compartment priority values to the central system or ECRV in response to a request command from the central system or ECRV.

  In an embodiment, the resident can select a dead band value (eg, a hysteresis value) for the thermostat used in calculation block 1902. When the dead zone value is relatively large, the temperature change in the section increases, but the movement of the vent is suppressed.

  In an embodiment, ECRV reports sensor data (eg, pipe temperature, air flow, air speed, power condition, actuator position, etc.) at regular intervals to the central system and / or compartment thermostat. In an embodiment, the ECRV sends the sensor data to the central system and the sensor data whenever the sensor data fails the threshold test (eg, exceeds the threshold, falls below the threshold, is within the threshold range, is outside the threshold range, etc.). Report to the compartment thermostat. In an embodiment, the ECRV reports sensor data to the central system and / or compartment thermostat in response to a request command from the central system or compartment thermostat.

  In an embodiment, the central system shown in FIGS. 7-9 is implemented in a distributed manner within the compartment thermostat 1100 and / or ECRV. In a distributed system, the central system does not necessarily exist as an individual device, but rather the functions of the central system can be distributed in the compartment thermostat and / or ECRV. Thus, in a distributed system, FIGS. 7-9 show a conceptual / computational model of the system. For example, in a distributed system, each compartment thermostat 100 knows the priority of that compartment, and the compartment thermostat 1100 in the distributed system negotiates and allocates heating / cooling air available between the compartments. In one embodiment of a distributed system, one of the compartment thermostats acts as a master thermostat to collect data from other compartment thermostats and execute calculation block 1902. In one embodiment of a distributed system, the compartment thermostat operates in a peer-to-peer fashion, and the calculation block 1902 is performed in a distributed fashion across multiple compartment thermostats and / or ECRVs.

  In an embodiment, the blower 402 can be used as a generator and supplies power to recharge the power supply 404 in the ECRV. However, using the blower 402 in such a manner limits the air flow in the ECRV. In an embodiment, the controller 401 calculates the opening of the vent for the ECRV and creates the desired amount of air passing through the ECRV while generating power using the blower and recharging the power supply 404 (in this way). Under such circumstances, the controller opens more blades than necessary to compensate for the air resistance of the generator blower 402. In an embodiment, the controller 401 can use the blower as a generator instead of increasing the blade opening to save power in the ECRV. The controller 401 can direct the power generated by the blower 402 to one or more power supplies 404, 405, or the controller 401 can dump excess power from the blower into a resistive load. In an embodiment, the controller 401 makes a determination regarding the relationship between the use of the blower and the opening of the vent. In an embodiment, the central system instructs the controller 401 when to use the vent opening and when to use the blower. In an embodiment, the controller 401 and the central system negotiate for vent opening and blower use.

  In an embodiment, the ECRV reports its power status to a central system or partition thermostat. In an embodiment, the central system or compartment thermostat takes such power status into account when determining a new ECRV opening. Thus, for example, if there are first and second ECRVs operating in one compartment, the central system changes the air to that compartment when the central system knows that the power of the first ECRV is low Sometimes the second ECRV is used. If the first ECRV can use a blower 402 or other airflow based generator for power generation, the central system will be in a relatively closed position relative to the second ECRV when directing air to that compartment And direct a relatively large air flow to the first ECRV.
