摘要： A fan includes a first wind wheel having a first rotation axis and a second wind wheel arranged opposite to the first wind wheel and having a second rotation axis. The first wind wheel includes a first hub and a plurality of first blades arranged around the first hub and spaced apart from one another. The second wind wheel includes a second hub not directly coupled to the first hub and a plurality of second blades arranged around the second hub and spaced apart from one another. The first blades and the second blades are tilted towards opposite directions along a circumferential direction.

摘要： An air conditioning system and a method for controlling the same are provided. The air conditioning system includes an enhanced vapor injection compressor, first and second direction switching assemblies, first and second heat exchangers and a flash evaporator. The enhanced vapor injection compressor has an air discharge port, an air supplement port, first and second air suction ports, and an air return port. Pressure in a sliding vane chamber of an air cylinder corresponding to the second air suction port is equal to a discharge pressure at the air discharge port. A first pipe port of the first direction switching assembly is connected with the second air suction port, a second pipe port thereof is connected with the air discharge port and a third pipe port thereof is connected with the liquid accumulator, and the first pipe port is communicated with one of the second and third pipe ports.

摘要： An air conditioner (100), comprising a compressor (110), a reversing assembly (120), an outdoor heat exchanger (130), an indoor heat exchanger (140), an electric control heat sink assembly (150), a first unidirectional throttle valve (160) and a second unidirectional throttle valve (160′). The electric control heat sink assembly (150) comprises an electric control component (151) and a heat dissipation assembly (152). The first unidirectional throttle valve (160), on the flow direction from a first valve port (161) to a second valve port (162), is completely turned on. On the flow direction from the second valve port (162) to the first valve port (161), the first unidirectional throttle valve (160) is a throttle component. The second unidirectional throttle valve (160′), on the flow direction from a third valve port (161′) to a fourth valve port (162′), is completely turned on. On the flow direction from the fourth valve port (162′) to the third valve port (161′), the second unidirectional throttle valve (160′) is a throttle component.
