  • Patent number: 11441800
    Abstract: Disclosed is a system and method for remote performance monitoring of a ventilation system. The method is independent of measuring electric meter current consumed or thermostatic data. The method uses two sensors to measure temperature and humidity. A first sensor is placed on a return grille, and a second sensor is placed on the supply grille. Using only data from the sensors, an on-off duty cycle is calculated. The on-off duty cycle is calculated for an on-time period during which the ventilation system is operating and an off-time period during which the ventilation system is not operating between the air as measured by the first sensor and the air as measured by the second sensor on the supply air grille. Machine learning with two or more datasets of the sensor data and the on-off duty cycle to indicate a component of the ventilation system is faulty.

  • Patent number: 11357134
    Abstract: A multiple mode cooling system circulates outside air through a data center to cool heat-generating information technology (IT) component(s). Based on outside and interior air temperature values and outside humidity value, a controller determines that outside air cooling poses a risk of damage to the heat-generating IT component(s) due to condensation or overheating. Controller also determines that compressor(s) of the cooling system have been inactive for less than a minimum off-time specified for maintaining service life of the compressor(s). In response, controller checks a cooling mode setting and, based on determining that a cooling mode setting indicates an optimization preference for avoiding the posed risk of damage to the heat-generating IT component(s) over compressor service life, the controller restarts the compressor(s) before expiration of the minimum off-time.

  • Patent number: 11237537
    Abstract: A system and method for advanced digital economization for an HVAC system having an economizer. A digital processing unit is configured to open a damper of an economizer within a dead-band range that allows for preemptive cooling prior to a call for cooling. This economization strategy allows for free cooling (outside air) without having to pay energy costs for cooled (air-conditioned) air. The system and method can be used with or without demand control ventilation (DCV). The method also includes a “self-learning” strategy with outside air and return air sensor to regularly sense past economizer damper modifications and average out recent readings to help set the dead-band range. The method can include the ability to work in conjunction with a variable supply fan speed control, provide fault detection, self-correct, auto-configure, and report system status.

  • Patent number: 11156572
    Abstract: A processor-implemented method of controlling an HVAC system transforms a comfort map into a plurality of sequential constant-temperature segments that are used in generating a control temperature sequence that preserves occupant comfort while improving energy efficiency. The method balances user comfort, temperature trajectory execution complexity, operational HVAC trajectory realization, and energy efficiency. The system achieves this balance through utilization of comfort map metric data, analysis and control system execution. The system, comfort map metric data processing and analysis facilitates this balance by executing a control temperature sequence/temperature trajectories developed based on direct user comfort feedback data within the context of a comfort map and thermal equilibrium boundaries derived from the comfort map.
