An evaporative cooler which includes a sealed loop of conduit with a first portion in a space to be cooled and a second portion in a space where heat is rejected, a volume of working fluid, and a fan inside the conduit loop. The fan forces air over the working fluid to accelerate its evaporation, which requires heat. Evaporation creates vapor-enriched air which carries heat and is forced by the fan to the second portion. Within the second portion, the vapor-enriched air rejects the absorbed heat before being forced back to the first portion. In certain cases, a portion of the working fluid in the vapor-enriched air condenses out and drains or is pumped back to the first portion. In certain uses, the cooler provides cooling to an area. In other uses, the cooler captures vaporized water, producing an impurity-free condensate for removal or use.

The automatic air conditioner drain system sanitizer may comprise a pump, a controller, a solution reservoir, and a power source. The automatic air conditioner drain system sanitizer may be configured to dispense a drain clearing solution from the solution reservoir into a drain line of an air conditioning system periodically in order to prevent growth of microorganisms within the drain line. The microorganisms may be referred to as white slime and may comprise bacteria, algae, mold, mildew, fungus, or any combination thereof. As non-limiting examples, the drain clearing solution may be white vinegar, bleach, chlorine tablet dissolved in water, or a liquid drain line clearing product. The quantity of the drain clearing solution dispensed and the dispensing interval may be selected and may vary based upon the drain clearing solution used.

A system comprising a conditioning system with one or more cooling coils configured to allow air to pass through the cooling coils to reduce a temperature of the air as well as an extraction portion with a plurality of condensing plates configured to receive conditioned air and configured to cause a portion water vapor of the conditioned air to collect and form liquid water, and a reservoir configured to receive collected liquid water from the plurality of condensing plates.

A system for automizing an injection of a chemical treatment into an effluent drain line may include a containment tank, an injection pump disposed within the containment tank, at least one level switch disposed on or inside the containment tank, a flow line disposed at least partially within the containment tank, at least one flow meter disposed along the flow line, and a microcontroller. The microcontroller is configured to: maintain an off-time cycle, transmit a signal to the injection pump to pump a volume of chemical treatment stored in the containment tank into the flow line after the off-time cycle ends, track the volume of chemical treatment passing through the flow line with the at least one flow meter to produce a flow rate, inject the volume of chemical treatment from the flow line into an effluent drain line, track a current volume of the containment tank with the at least one level, and restart the off-time cycle.

A packaged terminal air conditioner (PTAC) system includes a wall sleeve in which a chassis is mounted. The wall sleeve includes a bottom configured as a drain pan to collect condensate from the chilling components of the chassis. At a side wall of the wall sleeve there is an aperture configured to allow a person to insert a treatment pellet. The treatment pellet is water soluble and contains an antimicrobial component that prevent or inhibits the growth of biological material that could obstruct the drain system of the wall sleeve and PTAC. A rotating cover is positioned at the side wall to normally cover the aperture and prevent foreign objects from entering the PTAC, but the rotating cover can be rotated so that a hole in the rotating cover aligns with the aperture, allowing insertion of the treatment pellet.

An inline drain sanitizing system, includes: a manifold assembly including an inlet port, an outlet port, and a treatment port, wherein: the inlet port is configured to be couplable to a condensate supply line and receive unsanitized condensate, and the outlet port is configured to be couplable to a condensate drain line and provide sanitized condensate; and a treatment subsystem configured to interface with the treatment port and process the unsanitized condensate to generate the sanitized condensate.

A liquid collection container removably connected to an air conditioning unit, the liquid collection container including a main body to store at least one liquid therein, a primary hose removably connected to at least a portion of the main body to direct the at least one liquid condensed from the air conditioning unit into the main body, and a pump disposed within at least a portion of the main body to extract the at least one liquid from within the main body and expel the at least one liquid from the main body.

Examples disclosed herein relate to a condensation device including a reservoir including one or more elements, a power supply, and a controller configured to receive time data and to control a device to transport the one or more elements to a condensation stream.

An antibacterial device that includes a substrate, a first electrode on the substrate, a second electrode on the substrate, and a protective layer covering the first electrode and the second electrode and having a first surface opposing of the substrate and a second surface opposite the first surface. Further, the first electrode and the second electrode are arranged such that the protective layer has an electric field strength on the second surface thereof of 150 kV/m or more when a voltage is applied to the first electrode or the second electrode.
