  • Patent number: 11592200
    Abstract: Embodiments of the disclosure provide a thermal model based on an adaptive filter bank for characterizing heat transfer of a volume of a thermal system. In one embodiment, the adaptive filter bank is used for diagnostics that provides information related to the condition of a thermal system. The diagnostics are based on an analysis of heat transfer characteristics of a dynamic representation of the thermal system. In accordance with the embodiments, thermal coefficients are generated based on an adaptive filter bank. One or more filters are applied to the thermal coefficients based on a sampling rate and one or more estimate thermal coefficient thresholds are generated based on the sampling rate. It is determined whether at least one of the thermal coefficients that is filtered satisfies at least one of the estimated thermal coefficient thresholds. Thereupon, alert information indicative of a diagnostic event is provided based on the determination.

  • Patent number: 11512863
    Abstract: A method of operating an HVAC system using a controller includes predicting a first predicted temperature of an enclosed space during an unoccupied time with the HVAC system off. The controller determines if the first predicted temperature is less than a set-point temperature. Responsive to a determination that the first predicted temperature is less than the set-point temperature, the controller predicts a second predicted temperature of the enclosed space if the HVAC system is operated for a first runtime. The controller determines if the second predicted temperature is less than the set-point temperature and, responsive to a determination that the second predicted temperature is not less than the set-point temperature, the controller operates the HVAC system for the first runtime.

  • Patent number: 6644398
    Abstract: A system and method for controlling delivery of conditioned water to a plurality of heat exchangers includes a system controller which gathers information as to the current and future demands for conditioned water by a plurality of zone controllers associated with the plurality of heat exchangers. The system controller is operative to provide conditioned water to the heat exchangers even though current demands for conditioned water may not be sufficient to require the provision of conditioned water to the heat exchangers. The system controller analyzes current demands for conditioned water in combination with future demands for conditioned water to determine if the combined demands exceed a minimum level or number of demands necessary to authorize provision of conditioned water to the heat exchanger.

  • Patent number: 6628997
    Abstract: A method for programming a thermostat, comprising the steps of providing a thermostat programmed to convert programming codes into time-temperature schedules; determining a desired time-temperature schedule; developing a programming code corresponding to the desired time-temperature schedule; and entering the programming code into the thermostat, whereby the programming code is translated into the desired time-temperature schedule. The schedule and programming code can advantageously be determined by a user by accessing a server via computer network, on a suitably programmed personal computer, by telephone, or by any other suitable method of allowing the user access to software for determining the schedule and developing the desired code.

  • Patent number: 6591901
    Abstract: A system and method for controlling delivery of either heated or cooled water to a plurality of heat exchangers includes a system controller which gathers information as to the current and future heating or cooling demands of a plurality of zone controllers associated with the plurality of heat exchangers. The system controller is operative to provide heated or cooled water to the heat exchangers even though current heating or cooling demands may not be sufficient to require the provision of heated or cooled water to the heat exchangers. The system controller analyzes current demands for heating or cooling in combination with future demands for heating or cooling to determine if there is any combination of current and future heating or cooling demands that exceed a minimum level or number of demands necessary to authorize heating or cooling.

The system controller is operative to provide conditioned water to the heat exchangers even though current demands for conditioned water may not be sufficient to require the provision of conditioned water to the heat exchangers. The system contoller does this by analyzing current demands for conditioned water in combination with future demands for conditioned water to determine if the combined demands exceed a minimum level or number of demands necessary to authorize provision of conditioned water to the heat exchangers.

    Abstract: A system for controlling delivery of either heated or cooled water to a plurality of heat exchangers includes a system controller which gathers information as to the current and future heating or cooling demands of a plurality of zone controllers associated with the plurality of heat exchangers. The system controller analyzes current demands for heating or cooling in combination with future demands for heating or cooling to determine if there is any combination of current and future heating or cooling demands that exceed a minimum level or number of demands necessary to authorize heating or cooling. A start time for the provision of the heated or cooled water is thereafter determined by the system controller in the event that there is any combination of current and future heating or cooling demands that exceed the minimum level or number of demands necessary to authorize a heating or cooling.

  • Patent number: 5822997
    Abstract: A thermal conditioning system is provided which is configured for setback operations. The source of thermal conditioning is preferably a gas driven heat pump. Control is provided such that during the recovery process, the operation of the heat pump is varied to accommodate changes in loading on the system. In addition, the control apparatus is configured to vary the start time of the recovery period as a function of recent system performance.

  • Patent number: 5555927
    Abstract: An adaptive recovery method for a setback thermostat using the intersection of the space temperature with a sloped recovery temperature line which approximates the change in temperature as a function of time during recovery of the temperature controlled space from a setback temperature, to determine the time at which recovery to the occupancy temperature should begin. The thermostat starts recovery when the current space temperature crosses the recovery temperature line. A useful feature of the apparatus and method which implement the invention, computes and constantly updates the slope of the temperature recovery line. The update of the temperature recovery line slope is based on miss time, i.e.

  • Patent number: RE48574
    Abstract: Systems and methods for estimating a time to cool down or warm up a building zone from a temperature setback condition are provided. A described method includes determining, by a controller for the building zone, at least one of a cooling demand for the building zone and a heating demand for the building zone for a time period corresponding to the temperature setback condition. The method further includes estimating a return time using at least one of the cooling demand and the heating demand. The return time is the time to cool down or warm up the building zone from the temperature setback condition.
