摘要： A duct detector may include a detection chamber and a control circuitry stacked vertically on top of the detection chamber. A sealing gasket may seal a contact between a substrate of the control circuitry (e.g., the seal may be at the bottom surface of a printed circuit board containing the control circuitry) and the detection chamber such that particles analyzed the detection chamber may not damage the control circuitry. Therefore, by providing a sealed barrier between the control circuitry and the detection chamber, the sealing gasket allows for stacking the control circuitry and the detection chamber. As the seal does not create a barrier (the barrier is for the detection chamber) for a repair personnel to access the control circuitry, repairs to the duct detectors may be easier because the seal may not have to be broken and resealed during the repair process.

摘要： Methods and related systems for diagnosing a loss of capacity of a heating, ventilation, and air conditioning (HVAC) system are disclosed. In an embodiment, the method includes summing a runtime of an auxiliary heat source of the HVAC system over a plurality of time blocks. Additionally, the method includes summing an expected runtime of the auxiliary heat source over the plurality of time blocks. Further, the method includes comparing the runtime sum with the expected runtime sum, wherein the expected runtime for each of the plurality of time blocks is a function of an outdoor ambient temperature over a time-delay block beginning before the corresponding time block.

摘要： Apparatuses, systems, methods, and computer program products for carbon dioxide based ventilation monitoring are described. An apparatus may include a carbon dioxide sensor, a processor, and/or a memory storing computer program code executable by the processor to perform operations. An operation may include interpolating a ventilation metric for an environment of a carbon dioxide sensor based at least partially on data from the carbon dioxide sensor using carbon dioxide as a proxy for ventilation. An operation may include performing a predefined action based on a ventilation metric.

摘要： The present disclosure relates to a control system for a heating, ventilation, and/or air conditioning (HVAC) system. The control system includes a user interface configured to receive a first input indicative of a first expected operating range of a first parameter in a first zone and to receive a second input indicative of a second expected operating range of a second parameter in a second zone. A first set point for the first parameter is within the first expected operating range and a second set point for the second parameter is within the second expected operating range. The control system includes a controller configured to manage operation of the HVAC system and to provide a first alert in response to the first parameter being outside of the first expected operating range and a second alert in response to the second parameter being outside of the second expected operating range.

摘要： A sensor in a building HVAC system includes a transducer configured to measure a variable in the building HVAC system and to generate a sensor reading indicating a value of the measured variable. The sensor includes a communications interface configured to provide the sensor reading to a control device in the building HVAC system and a near field communication (NFC) circuit separate from the communications interface. The NFC circuit is configured to facilitate bidirectional NFC data communications between the sensor and a mobile device. The sensor includes a processing circuit having a processor and memory. The processing circuit is configured to wirelessly transmit data stored in the memory of the sensor to the mobile device via the NFC circuit, wirelessly receive data from the mobile device via the NFC circuit, and store the data received from the mobile device in the memory of the sensor.

摘要： A system and method of retrofitting a heating, ventilation, air conditioning, and refrigeration system (HVACR) including one or more brazed, soldered, or mechanical connections between refrigerant lines is disclosed. The method includes removing a refrigerant from the HVACR system. The refrigerant that is removed is a non-flammable refrigerant. An enclosure is installed over the one or more brazed, soldered, or mechanical connections between refrigerant lines. A refrigerant is added to the HVACR system. The refrigerant being added has a global warming potential (GWP) that is relatively lower than the refrigerant removed from the HVACR system. The refrigerant being added has a relatively higher flammability than the refrigerant removed from the HVACR system.
