摘要: A device is configured to operate a Heating, Ventilation, and Air Conditioning (HVAC) system. The device is further configured to determine that the amount of time to close a pressure switch exceeds a time threshold value. The device is further configured to receive an audio signal from a microphone while operating the HVAC system, to identify an audio signature for the combustion air inducer, and to determine the audio signature for the combustion air inducer is present within the audio signal. The device is further configured to determine a fault type based on the determination that the audio signature for the combustion air inducer is present within the audio signal, to identify a component identifier for a component of the HVAC system that is associated with fault type, and to output a recommendation identifying the component identifier.

摘要: An air conditioner of the present embodiment includes a heat exchanger unit in which an installation position of a suction temperature sensor can be changed and the air conditioner is capable of determining whether the installation position of the suction temperature sensor is correct. During a cooling operation, a heat exchange temperature is lower than a suction temperature, and during a heating operation, the heat exchange temperature is higher than the suction temperature. However, if a suction temperature sensor is incorrectly disposed on a downstream side of a flow of air in an indoor heat exchanger, the suction temperature detected by the suction temperature sensor is a temperature of indoor air after exchanging heat with a refrigerant in the indoor heat exchanger, so that the heat exchange temperature and the suction temperature are close to each other regardless of the cooling operation or the heating operation.

摘要: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing thermal modeling. In one aspect, a method includes receiving monitoring data comprising temperature data measured inside a site, mode data, and state data, receiving weather data descriptive of weather at the site, and aligning the received temperature data, mode data, and state data with the received weather data. The method also includes determining an internal heat gain representing an amount of heat generated at the site irrespective of the heating or cooling system, determining at least one of a thermal product for the site or a thermal potential for the heating or cooling system, generating, based on the internal gain and the thermal product or the thermal potential, a thermal model for the site, and providing, as output, the generated thermal model.

摘要: A system for assessing an indoor space for favorable conditions for the transmission of a viral particle is disclosed. A set of sensors measure a set of environmental parameters, and a processor is configured to combine the measured set of environmental parameters into a single scale of numerical or descriptive value representing the favorability of viral transmission in the indoor space.

摘要: An air conditioner, a control method for an air conditioner, and a computer-readable storage medium are provided. The air conditioner has a body, an air outlet, and an air output assembly for adjusting the air output of the air outlet. The air conditioner further has a detection device and a controller. The detection device acquires a distance value of a target object from the air conditioner. The controller is electrically connected to the air output assembly and the detection device, and controls the air output assembly to switch among different operative configurations based on the distance value.

摘要: A freeze protection system for a heating, ventilation, or air conditioning (HVAC) system is shown. The freeze protection system includes a temperature sensor positioned at an inlet of a coil within which a liquid is at risk of freezing, and a controller comprising a processor and memory. The memory stores instructions that are executed by the processor. The processor is instructed to obtain a measured temperature of the liquid at the inlet of the coil from the temperature sensor, compare the measured temperature of the liquid at the inlet of the coil with a freeze prevention temperature threshold, engage a freeze prevention action in response to a determination that the measured temperature of the liquid at the inlet of the coil is less than or equal to the freeze prevention temperature threshold.
