A method for cleaning an air conditioner includes: in response to a cleaning instruction, controlling frosting on the surface of a target heat exchanger; after a frosting completion condition is met, controlling defrosting of the frost on the target heat exchanger; and after a defrosting completion condition is met, reducing the surface temperature of the target heat exchanger to a sterilization temperature, and carrying out quick cooling sterilization, wherein the temperature difference between the sterilization temperature and the defrosting temperature during defrosting meets a set temperature change sterilization condition. By a frosting-defrosting process, dirt such as dust on the heat exchanger may be effectively stripped and deep bacteria may be exposed, and then the quick cooling sterilization process may kill the bacteria by utilizing the sharp temperature change during switching from the defrosting process to the quick cooling process. Also disclosed is the air conditioner.

An apparatus and method for cleaning split system air conditioning units. The apparatus comprises a shield functioning as a moisture barrier that sits between the wall and the AC unit and which releasably receives a drain pan that interconnects with the bottom of the shield to form a water tight seal. A flexible tube connects the bottom of the drain pan to a collection receptacle. Water and chemical sprayed into the unit to clean the unit drain through the unit, into the drain pan, through the tubing, and are collected by and can be disposed of from the receptacle. After the AC unit is cleaned, the drain pan, tubing and collection receptacle are removed leaving the area clean and dry. Kits comprising the apparatus of the invention can be sold together with new AC units or purchased separately.

A heat exchanger cleaner apparatus for spraying a cleaning composition into an interior of an air handler of an air conditioning system includes a spray outlet assembly, a pump device, and a controller. The spray outlet assembly is configured to be inserted into the interior of the air handler to be directly exposed to an outer surface of a heat exchanger of the air handler. The pump device is configured to pump an amount of the cleaning composition through the spray outlet assembly such that the spray outlet assembly sprays the amount of the cleaning composition as a fluid stream. The controller is configured to operate the pump device to cause the amount of the cleaning composition to be supplied through the spray outlet assembly without manual intervention.

A purification structure is located beside an inlet segment of a heat dissipator and contains: a casing, a water mesh, a water distribution seat, and a water collection device. The casing includes an air inlet and an air outlet. The water mesh includes multiple orifices and is accommodated between the air inlet and the air outlet of the casing. The water distribution seat is secured on a top of the water mesh and includes an aperture and multiple passages. The water collection device communicates with a bottom of the water mesh, and the water collection device includes a water accommodation chamber and a pump, wherein the pump has a water output segment connecting with a guide tube which communicates with the aperture of the water distribution seat, such that the water is outputted by the pump to flow toward the aperture via the guide tube.

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.

An apparatus is disclosed that is designed to be able to clean HVAC condensers. The apparatus comprises a plurality of pipes that facilitates the passage of water through them allowing water and/or a cleaning solution to clean the condenser by spraying the condenser with sprayers without having to move the apparatus. The apparatus is designed so as to be able to spray every part of the condenser without having to move the apparatus. The apparatus may also have a timer associated with it that allows the condenser to be cleaned at periodic intervals.

An HVAC fluid dispersant system. The HVAC fluid dispersant system includes one or more fluid lines, the one or more fluid lines configured to allow movement of a fluid and a pump, the pump configured to move the fluid through the one or more fluid lines. The HVAC fluid dispersant system also includes a source line, the source line configured to provide the fluid to the pump and a nozzle. The nozzle is configured to receive the fluid from the one or more fluid lines, create a mist composed of the fluid and attach to a duct vent.

A foaming cleaner includes a composition that includes water about 50 wt. % to about 60 wt. %, a solvent about 20 wt. % to about 50 wt. %, a surfactant about 0.5 wt. % to about 2.5 wt. %, and a pH and corrosion control agent comprising 30% ammonia solution about 1.25 wt. % to about 1.75 wt. %. The composition is configured to form a foam for cleaning an evaporator coil.

An apparatus configured to dispense a cleaner composition includes an apparatus outlet in fluid communication with an exterior of the apparatus, a dispenser device configured to be operated to selectively dispense an amount of the cleaning composition through the apparatus outlet, and a controller configured to operate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention. The apparatus is configured to be electrically connected with a float switch concurrently with dispensing the cleaning composition, and the apparatus is configured to cause at least a portion of an air conditioning system to shut down in response to receiving a signal generated by the float switch.
