Enhancements to an air handler of an air conditioning system. The enhancements can include a scent dispersion system, a heat exchanger rinse system, and/or an air handler condensation drain pipe flush system. The scent dispersion system employs a pressure differential established within the air handler to draw a scent mist from a scent reservoir. The scent is disbursed throughout the structure by the air conditioning ventilation system. The heat exchanger rinse system dispenses a rinse fluid onto the heat exchanger. A cleaning composition can be injected into the rinse fluid to aid in the cleaning process. The flush system automatically configures a check valve upstream of the flush injection point. A flush fluid flows through the drain pipe applying a pressure to dislodge a blockage therein. A chemical composition can be added into the flush fluid to assist in the dislodging process.

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 condensate drain line cleaning system including a coil attachment assembly and a drain attachment assembly is disclosed herein. The coil attachment assembly includes a tubing body configured to be connected to the drain line that is attached to the evaporator coil of an existing air conditioning unit. The drain attachment assembly is configured to be connecting to the existing drain line located outside a user's home. A user then pours a cleaning solution into an opening in the coil attachment assembly. Afterwards, a user then actuates a shut off valve disposed on the drain attachment assembly. A user then pours hot water into the opening of the coil attachment assembly to activate the cleaner therein. After waiting a certain amount of time, the user may then re-open the shut of valve to drain all the waste present in the drain line.

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.

An indoor unit of an air-conditioning apparatus includes a heat-medium heat exchanger, an air vent valve, a drain pan, and a hose. The heat-medium heat exchanger is provided in a housing to cause heat exchange to be performed between a heat medium and indoor air. The air vent valve allows air to escape from a heat medium passage that allows the heat medium to flow in the heat-medium heat exchanger. The drain pan is provided below the heat-medium heat exchanger to receive condensation water generated at a surface of the heat-medium heat exchanger. The hose has flexibility, and is attached to the air vent valve, and provided to let out the air along with the heat medium from the heat medium passage to the inner space in the drain pan. The hose has a double-wall structure and an upper end portion of the hose is fixed to the air vent valve.

A body of a casing is provided with a predetermined component. An imaging device includes an attachment portion detachably attached to the component so as to be at a position at which the imaging device can image the at least one predetermined object to be imaged.

A condensate drain assembly includes a drain pan configured to receive condensate from an evaporator coil of an air conditioning system. The drain pan is configured to be removed from the air conditioning system. The condensate drain assembly also includes a drainage pipe configured to translate the condensate from the drain pan to a drain located beneath the air conditioning system and a drain pan end cap. The drain pan end cap includes a first aperture configured to drain the condensate from the drain pan and a second aperture configured to align with the drainage pipe.

A drainage mechanism is connected to a drain pump that sucks water from a drain pan. The drainage mechanism includes a connecting part that connects to the drain pump, a first flow path, a folded part, and a second flow path. The first flow path extends upward from the connecting part. The folded part has a first end connected to an upper end of the first flow path and a second end on a side opposite to the first end. The folded part changes a direction of the water flowing therein from upward to downward. The second flow path extends from the second end. The second flow path is a pipe that has an inner diameter of 13 mm or less. The flow path area of the folded part is larger than the flow path area of the second flow path.

A dehumidifier is provided that may include a bucket; a drain pan comprising a drain passage configured to guide condensed water dropped from an evaporator to the bucket; a pump; a barrier configured to define a bucket space in which the bucket is accommodated; and a pump water inlet line and a pump water outlet line, which are connected to the pump. The pump water inlet line may include a flexible tube a portion of which is inserted into the bucket. The bucket may have an opening into which a portion of the flexible tube may be inserted. A portion of the flexible tube may be bent to be easily inserted into the bucket through the opening of the bucket.

The air conditioner according to the present disclosure may comprise a heat exchanger exchanging heat between air and refrigerant, a fan discharging air toward the heat exchanger, a first drain pan disposed in a direction crossed to a direction of air flowing from the fan to the heat exchanger, wherein the first drain pan has an inlet opening through which air discharged from the fan flows toward the heat exchanger, a second drain pan disposed in a direction parallel to a direction of air flowing from the fan to the heat exchanger and a water level sensor rotatably disposed with reference to a rotating center spaced apart from the first drain pan and the second drain pan, wherein the water level sensor detects a water level of water gathered in one of the first drain pan and the second drain pan.
