An electrostatic precipitating apparatus for an air conditioning system is disclosed. The precipitating apparatus includes an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied and a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded, a washing water supply spraying the washing water to the electrostatic precipitator, and a frame assembly fixed to the duct to support the electrostatic precipitator. The frame assembly is fixed to the duct to support the electrostatic precipitator, and includes a prestressing locking member fixed to inside of the duct in a state in which a pressing force is applied to the electrostatic precipitator.

A filter section of a heating, ventilation, and air conditioning (HVAC) system includes a plurality of filters arranged in series relative to a flow path of air through the filter section. The plurality of filters includes at least one movable filter transformable between an extended position arranged within the flow path of air and a retracted position removed from the flow path of air. At least one movement mechanism is operably coupled to the at least one movable filter to transform the at least one movable filter between the extended position and the retracted position.

Systems, apparatus and methods for disinfection of airflow. An apparatus for disinfecting air-conditioned airflow in a confined space includes: a modular housing; and a disinfection chamber enclosed within the housing. The disinfection chamber includes a plurality of disinfection sheets. Each disinfection sheet comprises a plurality of ultraviolet (UV) light sources. The airflow is configured to be routed along a serpentine pathway within the housing to expose microorganisms in the airflow to far UV-C light emitted by the UV light sources for an extended and optimal duration.

The present disclosure provides for filters, filter systems, methods of using filter systems, and methods of detecting targeting airborne particles, and the like. The present disclosure provides for filters that can capture one or more types of targeted airborne particulates, where the presence of each of the targeted airborne particulates can then be detected. The filters can be used in industrial gas systems, laboratory gas systems, HVAC systems, portable filter systems, respirator systems, and other residential, commercial, or industrial air circulation or air control systems.

A frame for a foldable and disposable air filter media is disclosed. The frame has a frame base and a frame cover having a size to overlap the air filter media. The frame cover is attached to the frame base by hinges allowing movement of the frame cover between an open position and a closed latched position. The closed frame holds the air filter media between the frame base and frame cover when in the closed position. The frame base includes an air flow monitoring system with an air pressure differential sensor to determine when the filter needs to be replaced. The frame also has capability to hold additional sensors for monitoring environmental conditions. A processor and memory enable collection and storage of sensed data. A communication module on the frame communicates air filter media change requirement to external devices including hand-held devices or a cloud server.

Computer-implemented systems and methods for estimating a replacement status of an HVAC air filter. Outdoor weather data (e.g., outdoor temperature information), is obtained. A Total Runtime Value of the HVAC system is determined based upon the obtained outdoor weather data. Finally, a replacement status of the air filter is estimated as a function of a comparison of the Total Runtime Value with a Baseline Value. By correlating air filter replacement status with an estimated runtime of the HVAC system, a credible predictor of air filter usage is provided. By estimating fan runtime based on easily-obtained outdoor weather data, the methods are readily implemented with any existing HVAC system and do not require installation of sensors or other mechanical or electrical components to the HVAC system.

Listed are some of this invention's unique features for producing a healthier home and a safer clothes dryer vent within the same housing system, which may be installed within a typical wall system or as a free-standing unit in a laundry room.

Included are two airflow receiving ports that accepts airflow from a clothes dryer or optionally from a house's interior rooms and two airflow exhaust ports that discharge the same airflow into an exhaust pipe to the outside or optionally into the building interior as recycled airflow.

A drainage device removes water derived from condensate which forms in the exhaust pipe and otherwise flows back into the housing.

Two (2) receiving ports and the two (2) exiting ports combine to provide four (4) combinations of airflow management.

The choice of which of the four (4) airflow ports are activated for airflow passage is subject to a selection from a control system which contains switches for the desired airflow management thru the housing.

Additionally, the control system contains monitors and sensors to indicate unsafe temperatures, air pressure changes or filter blockage within the housing.

A shutdown mechanism within the control system stops the airflow exhaust fan and stops the clothes dryer to provide an additional measure of safety.

Included in the invention is a multi-filter filtration system that includes filters that block lint particulate from a clothes dryer and block indoor pollutants comprising pre-filters, True HEPA filters, with activated carbon filters and air cleaners to meet EPA Indoor Air Quality Standards and MERV Ratings.

A multi-speed airflow exhaust fan moves airflow in thru the receiving ports, thru the multi-filters and out thru the exiting ports. Additionally, within the housing, access openings with removable windows provide internal inspections and accessibility.

In conclusion the elements of this invention combine to improve the efficiency and safety of a clothes dryer's exhaust system and improve the indoor air quality of a home or commercial building.

A filter, a manufacturing method for a filter, and an air conditioner are provided. The filter includes a casing, a transition tube, and a filter screen assembly. The filter screen assembly is provided in the casing, fitted with and connected to an inner wall of the casing, the casing is an integrally formed piece, and two axial ends of the casing have neck sections, and two neck sections are both fixedly connected to the transition tube.

An air purification and disinfection system includes an apparatus having a housing, an ultraviolet disinfection chamber, an air mover, and an air distribution unit in communication with the disinfection chamber. Air is passed through the disinfection chamber where it is purified and disinfected before it is delivered to the user of the apparatus through the air distribution unit. The apparatus can be configured as an open or a closed circuit system. The system may be configured to purify air in an airplane, a conference room, a classroom, or as a portable unit for an individual user. As a portable unit the disinfection chamber can be incorporated into a back pack, a vest, a purse, a briefcase, a shoulder bag, a cervical collar, or any other format for being carried by the user.
