    摘要： The present disclosure related to an air purifier. The air purifier of the present disclosure includes: a case having a cylindrical shape and having a plurality of air suction ports formed in a circumferential wall; a filter disposed inside the case and filtering foreign matter in an air introduced through the air suction port; a fan disposed above the filter and flowing the air introduced through the air suction port in an upward direction; a fan housing disposed above the filter and forming a fan space in which the fan is disposed; a fan motor disposed above the fan and rotating the fan; and a cover protruding from the fan housing into the fan space so as to be disposed outside the fan, wherein a lower end of the fan is disposed by a certain distance from a lower wall of the fan housing to an upper wall, and the cover protrudes above the lower end of the fan from the lower wall of the fan housing.

    摘要： A heating, ventilation, and air conditioning (HVAC) control system generates a request to replace a first air filter installed in an air handler of an HVAC system with a second air filter. The second air filter has a particulate matter removal efficiency rating that is greater than a particulate matter removal efficiency rating of the first filter. The system delays for a predetermined period of time and then obtains (i) a first temperature of air downstream of the air handler and (ii) a second temperature of air upstream of the air handler. The system then calculates a temperature difference between the f temperatures and determines whether the temperature difference is within an acceptable range. In response to the temperature difference being within the acceptable range, the system (i) operates the HVAC system using the second air filter and (ii) generates an alert indicating compatibility of the second air filter.

    摘要： An air filtration device including a housing that includes an air intake and a blower motor mounted within the housing, wherein when the blower motor is in operation, the blower motor generates an air flow from the air intake through an air duct extending vertically from the housing. The air filtration device also includes an air outlet at a distal end of the air duct, wherein the air outlet comprises at least one aperture, wherein when the blower motor is in operation, the air outlet discharges the air flow in a horizontal plane over an occupied zone from a region of the air duct having a vertical height that is less than or equal to twelve inches, wherein the region of the air duct for the air outlet is disposed at least thirty-six inches above the air intake. The air filtration device also includes an air filter.

    摘要： A multi-piece air filter housing, air filter assembly, and method for assembling an air filter for use with a heating, ventilation, and air conditioning (HVAC) systems or stand alone air circulation devices. In one example at least a first sidewall section and a second sidewall section include sidewall connectors allowing the first and second sidewall sections to be connected defining an interior cavity for receipt and support of air filter media. In one example, the air filter housing includes four modular sidewall sections that are connected together to form the air filter housing. A housing connector is used to secure the air filter housing and filter media circumferentially around a forced air passage opening to direct airflow through the air filter housing and filter media. In one example, the air filter assembly is useful for suspending ceiling HVAC vents.

    摘要： An air cleaner includes: a housing including a suction portion suctioning air and a discharge portion discharging air, a frame disposed inside the housing, a sterilizer sterilizing the suctioned air, a filter assembly filtering air, a blower moving air, a flow converter disposed on a top surface of the housing, guiding a flow of air, and discharging air inside the housing to an outside, and a guide guiding a direction of the flow converter. The sterilizer includes a sterilizing light source generating sterilizing light, a first sterilizing casing accommodating the sterilizing light source, and a second sterilizing casing coupled to a lower portion of the first sterilizing casing and supporting the first sterilizing casing and the sterilizing light source, where a portion of the first sterilizing casing is spaced apart from the second sterilizing casing to define a space therebetween that dissipates heat generated from the sterilizing light source.
