Abstract: A controller is configured to operate a heating, ventilation, and air conditioning (HVAC) system based on a first plurality of particulate matter measurements and a second plurality of particulate matter measurements. The controller is configured to determine an air filter efficiency for an air filter based on the received first plurality of particulate matter measurements and the received second plurality of particulate matter measurements. The controller is further configured to determine if a quantity of particulate matter in an airflow exceeds a first threshold value based on the received second plurality of particulate matter measurements. In response to determining that the quantity of particulate matter in the airflow does exceed the first threshold value, the controller is configured to transmit a notification indicating an action to inspect the air filter.

Abstract: A method for detecting a blockage in a filter mesh of an indoor unit includes: obtaining a first resistance difference value of the filter mesh under a preset air volume value; determining a first external static pressure value during an operation process of the indoor unit; and determining that the filter mesh is blocked based on a numerical relationship between the first external static pressure value, the preset external static pressure value, and the first resistance difference value. The blockage of the filter mesh may be determined in time during the operation process of the air conditioner.

Abstract: The present invention relates to a means of reducing exposure to aerosolized particulate pathogens thereby (1) safely increasing throughput, (2) increasing surgical flow rates and (3) improving surgical suite turnover times (i.e., limiting non-productive facility space utilization) through air quality monitoring, generally. Further, the present invention couples air quality sensors with real-time processing technology by combining algorithmic enabled and mechanical means of lowering risk levels of both patients, medical professionals and ancillary staff alike.

Abstract: An image registration unit of a maintenance assist apparatus registers in cleaning service information where usage status of a cleaning service on an air conditioning machine is set, a filter image obtained by a maintenance person photographing a filter of the air conditioning machine. A registration confirmation unit determines whether or not the filter image has been registered in the cleaning service information, when a completion report which reports completion of the cleaning service is received from the maintenance person, outputs to a maintenance terminal apparatus, a completion confirmation notification which notifies that the completion of the cleaning service has been confirmed, when it is determined that the filter image has been registered, and outputs to the maintenance terminal apparatus, a registration warning notification which prompts registration of the filter image, when it is determined that the filter image has not been registered.

Abstract: An air filter and a method of air filtration using the air filter are described. The air filter may comprise a filter media adapted to capture and filter one or more impurities from air. Further, one or more sound wave generators are attached at one or more sides of the filter media. The one or more sound wave generators generate acoustic waves to be propagated into the filter media. The air filter may further comprise a plurality of sensors positioned before the filter media and after the filter media. Further at least one fan is positioned before or after the filter media. Further an IoT is configured to control frequency of the acoustic waves generated by the one or more sound waves generators, and interconnected with power signal control panel parallel, AHU to control rotational speed of the at least one fan based on value provided by the plurality of sensors.

Abstract: There is described a system and method for configuring, commissioning and troubleshooting an HVAC unit. A unit type configuration is established based on a type of HVAC system and temperature data, humidity data, and/or indoor air quality data. A fan configuration is established based on whether a variable frequency drive fan is identified. Cooling and heating stage configurations are established based on a compressor parameter and a heating stage parameter. An available auxiliary termination is identified in response to establishing the configurations. A safety is assigned to the available auxiliary termination in response to identifying the available auxiliary termination. An IO table is provided to an HVAC controller, which includes physical input/output assignments for the terminations of the HVAC controller based on the configurations and the assigned safety. For another embodiment, the fan configuration is established based on one of a traditional stage blower fan or variable frequency drive fan.
