The invention discloses a control method and device for condensation prevention of an air conditioner and belongs to the technical field of condensation prevention of air conditioners. The control method includes the steps of obtaining first operation parameters and indoor environment parameters of the air conditioner, and controlling the air conditioner to be switched to operate in a heating mode when the first operation parameters and the indoor environment parameters meet preset condensation prevention starting conditions. According to the control method for condensation prevention of the air conditioner, the air conditioner can be switched to operate in the heating mode when the condensation prevention starting conditions are met, water drops condensed inside an indoor unit can be evaporated into water vapor through heat of a high-temperature refrigerant conveyed to an indoor heat exchanger, and thus the quantity of liquid water inside the indoor unit is reduced, the problems of condensed water dripping, water blowing during air exhausting and the like of the air conditioner are avoided, and the operational performance and user experience of the air conditioner are improved.

An air conditioner having a compressor, refrigerant condenser coil and accumulator submerged in water in a water tank, wherein the water is cooled by evaporative cooling when air is drawn through water sprayed into an air inlet duct communicating with the water tank. The compressor is cooled by the water in the water tank which is cooled by evaporative cooling. The water level in the water tank is maintained by a float valve connected to a water line to replenish evaporating water.

System and method are provided for removing condensate from an air-to-liquid heat exchanger of a combined air / liquid enclosed apparatus for cooling rack-mounted electronic equipment. The condensate removal system includes a condensate collector for collecting liquid condensate from the air-to-liquid heat exchanger, and a vaporizing chamber in fluid communication with the condensate collector for receiving collected liquid therefrom. An actively controlled vaporizer vaporizes collected liquid within the vaporizing chamber and a vapor exhaust is in communication with the vaporizing chamber for venting vapor from the vaporizing chamber outside the cabinet containing the combined air / liquid cooling apparatus and rack-mounted electronic equipment.

A drain pan for capturing condensate from a cooling coil in an air conditioning system is configured to facilitate condensate drainage from the pan and to inhibit accumulation of condensate therein. The pan includes troughs for collecting condensate and for channeling the condensate to the front part of the pan where the drain openings are located. A back trough has a central hump to enhance the flow of condensate from the back trough in both directions into opposed side troughs. The side troughs are sloped from back to front to conduct the condensate into a front trough to facilitate drainage from the pan. The lowermost portion of the front trough region is defined by a relatively narrow, non-flat area to reduce the amount of condensate residue in the pan.

The invention provides an air conditioner indoor unit with a self-cleaning function. The air conditioner indoor unit comprises a case, a humidifying assembly, a spray opening and a heat exchanger of the indoor unit. The case comprises a skeleton and a housing, wherein the skeleton is used for supporting a fan and the heat exchanger of the indoor unit, and the housing covers the skeleton and is provided with an air inlet and an air outlet. The humidifying assembly comprises a water tank and an atomization device used for atomizing water in the water tank. The spray opening is formed in the case and located in the air inlet upstream position of the heat exchanger of the indoor unit and used for outputting water mist formed by the atomization device. The humidifying assembly starts the atomization device when the air conditioner indoor unit executes the self-cleaning function, so that the spray opening is utilized to spray out the water mist to flow through the heat exchanger of the indoor unit, and accordingly the frosting degree at the heat exchanger of the indoor unit is improved. The heat exchanger of the indoor unit operates a condenser mode after frosting, and accordingly attached contaminants are taken away by water formed by defrosting. According to the scheme, the problem that a self-cleaning air conditioner cannot generate enough condensed water in the dry environment, and consequently the self-cleaning effect is affected is solved.

An outdoor unit for an air conditioner allows condensed water generated from an outdoor heat exchanger to be easily discharged, and prevents coldness from the outdoor heat exchanger from being transmitted to a bottom of the outdoor unit, thus preventing freezing of the condensed water on the bottom. The outdoor unit includes a cabinet having a bottom panel, an outdoor heat exchanger installed in the cabinet, and a support member made of heat insulating material supporting the outdoor heat exchanger with a spacing between a lower end of the outdoor heat exchanger and the bottom panel of the cabinet, to prevent condensed water generated from the outdoor heat exchanger from freezing.

The invention provides an automatic cleaning system, an air conditioner and a control method. The automatic cleaning system comprises a water storing device of which the first end is connected to an indoor unit condensed water collector and an outdoor unit condensed water collector, a cleaning water pump of which one end is connected to the second end of the water storing device and while the other end is connected to an indoor unit water sprayer and an outdoor unit water sprayer, a first detecting module for detecting the first operation state parameters of an indoor heat exchanger, a second detection module for detecting the second operation state parameters of an outdoor heat exchanger, and a control module for determining whether to start the cleaning water pump to automatically clean the indoor heat exchanger and / or the outdoor heat exchanger according to the first operation state parameters and / or the second state parameters. According to the technical scheme, the system has the advantages that the heat exchangers can be automatically cleaned, so that the timeliness and efficiency of cleaning of the heat exchangers can be effectively improved, and as a result, the operation reliability of the air conditioner can be improved; in addition, the condensed water can be recycled, and thus the water resource can be saved.
