  • Patent number: 10252201
    Abstract: The prevent invention addresses the problem of providing a multilayer filter medium for a filter having low pressure loss and high collection efficiency, a method for producing the same, and an air filter not only having low pressure loss and high collection efficiency but also being excellent in pleatability and wind-pressure deformation resistance. The multilayer filter medium for a filter as a means for resolution is obtained by laminating a wet-laid nonwoven fabric layer (2) on a wet-laid nonwoven fabric layer (1). The wet-laid nonwoven fabric layer (1) includes a nanofiber A having a single-fiber diameter within a range of 200 to 800 nm and a fiber length within a range of 0.4 to 0.7 mm, a fiber B having a greater single-fiber diameter than the nanofiber A, and a binder fiber C. The wet-laid nonwoven fabric layer (2) includes a nanofiber A having a single-fiber diameter within a range of 200 to 800 nm and a fiber length within a range of 0.4 to 0.

  • Patent number: 10247434
    Abstract: According to some embodiments, a heating, ventilating and air conditioning (HVAC) system comprises a circulation fan, one or more humidity sensors operable to sense humidity data associated with an enclosed space, and a controller. In operation, the controller receives the humidity data from the one or more humidity sensors and receives air quality data associated with at least one air pollutant. The controller determines, based on the air quality data, that a threshold associated with the air pollutant has been exceeded and determines, based on the humidity data, that a threshold associated with humidity has not been exceeded. The controller operates the circulation fan in response to determining that the threshold associated with the air pollutant has been exceeded and the threshold associated with humidity has not been exceeded, the circulation fan operated for filtration purposes while not servicing any conditioning demand.

  • Patent number: 10239009
    Abstract: A continuously-operable flow stream processing system and method has two or more fluid processing media arranged in a fluid conduit network to provide alternate flow paths for a flow stream to be processed (e.g. filtered). Valves and other flow control devices, e.g. controller module and sensors, are used to redirect the flow stream from one or more service-needed fluid processing media to service-ready fluid processing media without taking the system offline to remove, repair, replace, clean in situ, or otherwise service the service-needed fluid processing media, so that the system may operate continuously to process the flow stream without stoppage. Redirection into alternative flow paths and media may be automatically implemented based on a predetermined threshold or trigger condition, such as may be detected by sensors directly or indirectly monitoring media condition.
