摘要： A thermostat with voltage and current sensing capability is coupled directly to an HVAC unit and provides low latency failure detection and control using an on-board CPU. The thermostat can be configured to detect failure modes using current and voltage sensing and to make autonomous decisions to control the HVAC in response to such measurements.

摘要： Tools and techniques are described to automate commissioning of physical spaces. Controllers have access to databases of the devices that are controlled by them, including wiring diagrams and protocols, such that the controller can automatically check that each wire responds correctly to stimulus from the controller. Controllers also have access to databases of the physical space such that they can check that sensors in the space record the correct information for device activity, and sensors can cross-check each other for consistency. Once a physical space is commissioned, incentives can be sought based on commissioning results.

摘要： The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the ionizer and adjusts the high-voltage signals and ion concentration when VOC concentrations are above a threshold.

摘要： An outdoor unit of an air-conditioning apparatus includes: a refrigerant circuit in which a compressor and an outdoor-side heat exchanger are connected by a refrigerant pipe; an outdoor-side fan that sends air to the outdoor-side heat exchanger; and a controller including an inverter circuit configured to drive the compressor. The controller includes: a first heat generating component; a second heat generating component that generates a smaller amount of heat than the first heat generating component; a temperature detection circuit provided in the first heat generating component to detect a temperature thereof; a temperature acquisition module that acquires the temperature detected by the temperature detection circuit; and an estimate calculation module that calculates a temperature estimate of the second heat generating component based on the temperature acquired by the temperature acquisition module, and calculates an estimate of a life of the second heat generating component based on the temperature estimate.

摘要： Methods and systems for maintaining an atmosphere inside a habitat enclosing a work station and shutting down one, more than one, or all operational equipment inside and/or outside the habitat upon the occurrence of an adverse event. Concentrations of explosive, flammable, and/or poisonous gases or vapors are sensed, transmitted to a logic device, as are temperature, pressure, and/or humidity. HVAC units and air extraction units controlled by the logic device maintain acceptable pressure, temperature, and/or humidity. Any grit and dust may be extracted. Any explosive, flammable, and/or poisonous gases or vapors are extracted employing an emergency gas extraction sub-system controlled by the logic device. The logic device shuts down one, more than one, or all operational equipment inside and/or outside the habitat (for example as dictated by the client, law, or regulation) upon receiving one or more adverse event signals.

摘要： Embodiments include overflow sensor assemblies for water heaters, HVAC systems, and other devices for which temperature control systems may be used. An example overflow sensor assembly for detecting fluid leaks at a device may include a sensor probe configured to be in electrical communication with a power supply, and a sensor mounting bracket that forms a ground, where the sensor mounting bracket is configured to be adjustably coupled to a mounting surface on the device, such that the sensor mounting bracket can deflect about the mounting surface. The sensor probe is suspended from the sensor mounting bracket.
