A spraying system, a method and an apparatus for controlling the spraying system, an electronic device, a computer-readable storage medium, and an air conditioner are provided. The spray system includes a water outlet device, a spraying branch, a backflow branch, and a nozzle; a water outlet of the water outlet device, the spraying branch, and the nozzle are communicated sequentially; a solenoid valve is arranged in the spraying branch and/or the backflow branch, and the solenoid valve is used for controlling turning on and turning off of the spraying branch and/or the backflow branch; when the spraying branch is turned on, liquid flowing out of the water outlet device flows out of the nozzle through the spraying branch; when the backflow branch is turned on, the liquid flowing out of the water outlet device flows into the water outlet device through the backflow branch.

Systems and methods are provided for determining water pump status using current consumption. Within an HVAC system, water pumps may pump water from an indoor portion to an outdoor coil and/or an outdoor portion to an indoor coil to improve heat transfer within the HVAC system. To monitor the status of the water pumps (assessing whether the water pumps are properly pumping), the current consumption of the water pumps is measured and compared to pre-determined current value ranges. The HVAC system may determine whether the water pump is pumping only water, a combination of water and air, or no water, depending on the current value range that the measured current falls within. When the measured current lies within a particular current value range indicating that a water pump is not properly functioning, the HVAC system may take an action, such as issuing an alert or ceasing system operation.

A mobile air conditioner comprises a case, a first heat exchanger, a first air duct shell, an electric control box, an electric reactor assembly and an electric motor. The first air duct shell is located in the first cavity of the first housing and fixed to the first housing and located on the side of the first heat exchanger away from the base, and spaced apart from the first heat exchanger. The electric control box is located on the side of the first heat exchanger close to the first air duct shell, and is connected to the side wall of the first air duct shell close to the first heat exchanger. The electric reactor assembly is located in the first cavity and fixed to the base. The electric reactor assembly comprises a bracket and an electric reactor body.

A portable air conditioner unit includes a first heat exchanger, a second heat exchanger positioned below the first heat exchanger, and a spray pipe positioned between the first and second heat exchangers. The portable air conditioner unit also includes a valve that includes an inlet port, a first outlet port configured to direct fluid to a spray pipe, and a second outlet port configured to direct fluid to an exterior of the portable air conditioner unit. The portable air conditioner unit further includes a base pan defining a bottom reservoir within the portable air conditioner unit, a water level switch positioned in the base pan, and a pump positioned in the base pan. The pump is connected to the inlet port of the valve. The pump is operable to flow fluid from the base pan to the inlet port of the valve.
