A dispenser and procedure for disinfecting and cleaning air conditioner condensation drainage lines and other condensation drainage lines. The dispenser can be installed at any convenient location on any floor of a home or other building, regardless of whether the location is below, above, or at the same elevation as the inlet of the condensation drainage line. The dispenser includes a liquid pump for delivering an amount of treatment fluid into a treatment delivery line and an air pump for pushing the dose of treatment fluid through the treatment delivery line and into the condensation drainage line.

An air-conditioning condensate drain cleaning apparatus is provided. The apparatus includes a housing configured to suspend a condensate drain line cleaning fluid container therein, and a fluid dispensing unit configured to connect the cleaning fluid container to an air-conditioning condensate drain pipe and selectively control the rate at which the cleaning fluid is transferred from the cleaning fluid container to the condensate drain pipe. The fluid dispensing unit includes an elongated tube for transferring a fluid, a drip chamber for viewing the fluid, and a flow regulation clamp configured to control the rate at which the fluid is transferred from the cleaning fluid container to the condensate drain pipe. The housing includes a support member for suspending the cleaning fluid container therein, an elongated slot for viewing the cleaning fluid container, and a pair of apertures and protrusions for removably mounting the front portion to the rear portion.

Methods, systems, and apparatus, including computer programs encoded on computer storage media for identification and re-identification of fish. In some implementations, first media representative of aquatic cargo is received. Second media based on the first media is generated, wherein a resolution of the second media is higher than a resolution of the first media. A cropped representation of the second media is generated. The cropped representation is provided to the machine learning model. In response to providing the cropped representation to the machine learning model, an embedding representing the cropped representation is generated using the machine learning model. The embedding is mapped to a high dimensional space. Data identifying the aquatic cargo is provided to a database, wherein the data identifying the aquatic cargo comprises an identifier of the aquatic cargo, the embedding, and a mapped region of the high dimensional space.

A hybrid air conditioning system for cooling a chamber, the hybrid system including a desiccant-coated heat pump configured to cool, through evaporation and condensation of a refrigerant, a first air stream OA, and an indirect evaporative cooling, IEC, unit configured to cool a second air stream MA, which is related to the first air stream OA, through direct heat exchange between wet channels that are placed adjacent to dry channels. The desiccant-coated heat pump is fluidly connected to the IEC unit so that a generated supply air stream SA is dehumidified by a desiccant material coated on first and second heat exchangers of the desiccant-coated heat pump.

A system is provided for cleaning out a drain line for an air conditioning unit. The system has an access member that can be installed and remain in the drain line. The access unit provides access to the drain line to allow a fluid to move in at least one direction to remove the debris and liquids from the drain line to prevent maintenance issues with the air conditioning unit. A connecting member is used with the access member to move the debris either down the drain line or out of the air conditioning unit.

An aerosolized HVAC/R system solvent for decontaminating HVAC/R components and line sets The solvent contains 25-90 wt % propellant, and 10-75 wt % solvent mixture which is about 60-95 wt % trans-1,2, dichloroethylene, about 5-20 wt % n-propanol, and an inerting constituent providing a weight percent ratio of the inerting constituent to n-propanol of less than 1.5. The solvent is packaged in a container that is connected to the HVAC/R components or line sets to be decontaminated for supplying the solvent mixture under pressure to the HVAC/R components or line sets.

An air conditioning system, capable of automatically unclogging an air handler condensate drain tube, includes a primary fluid control valve to allow or prevent draining from the air handler through the condensate drain tube, and at least one secondary fluid control valve for allowing or preventing fluid flow from a cleaning fluid source to the condensate drain tube. First and second condensate sensors may sense condensate accumulation in two areas arranged one higher than the other. A controller may sense an activation of the first and second condensate sensors, and may close the primary fluid control valve preventing fluid flow from the condensate drain tube into the air handler, and open the secondary fluid control valve or valves enabling fluid flow from the respective cleaning fluid source to the condensate drain tube, to break and drain out a clog formed in the condensate drain tube.

A filtered air vent apparatus has a vent housing body comprising a first sidewall and a second sidewall defining a portion of an air passageway that extends between at least a first open end and a second open end. There is a grill hingedly attachable to the vent housing body and securable to the vent housing body. A connector provides a snap-in configuration that permits or effectuates toolless installation of the filtered air vent apparatus. A filter is selectively and removably positioned behind the grill and in the air passageway. The grill may be removable connected to the vent housing body to allow the grill to be cleaned a number of different manners.

A filtration system for a datacenter or other building can include filter media arranged in an airflow path between an inlet and an outlet each configured for air flow therethrough relative to a chamber. The chamber may be defined at least in part by walls and a floor of a room of the building, for example. The filtration system can further include a dust dislodgment system that dislodges dust accumulated in the filter media. For example, dislodged dust may be permitted to fall toward the floor. The filtration system can further include a dust collection system for collecting and/or removing dislodged dust, such as from the floor.

A system for humidifying and cooling an air flow and includes a frame, porous evaporation panels mounted on the frame, water dispersing elements arranged above the panels and a supply system including a control unit configured to supply water to the dispersing elements. The control unit includes the control elements that can be independently controlled from each other between an evaporation configuration wherein the water supply flow-rate is equal to a flow-rate of the water that is evaporated through the associated porous evaporation panel, and a cleaning configuration wherein the water supply flow-rate is greater than a flow-rate of the water that is evaporated through the porous evaporation panel, so as to create a water flow.
