Abstract: Disclosed in the present invention are a zero-load output non-stop control method and apparatus, and a unit. The apparatus comprises: a three-way valve, provided at an exhaust port of a compressor; a mixing tank, provided between an air suction port of the compressor and a condenser and used for mixing a refrigerant discharged by the compressor with a refrigerant throttled by the condenser; a first electronic expansion valve, provided on a first pipeline from the condenser to the mixing tank and sued for controlling the amount of the refrigerant throttled by the condenser and entering the mixing tank; and an electromagnetic valve, provided on a second pipeline between the three-way valve and the mixing tank and used for controlling the amount of the refrigerant discharged by the compressor and directly entering the mixing tank.

Abstract: A split-style electric skateboard includes a main skating board, an auxiliary skating board, and a cross beam located between the main and auxiliary skating board. The main skating board has a steering wheel and a driving wheel arranged one behind the other. A driving motor is mounted in the driving wheel and the steering wheel is connected to the main skating board by a first steering support and a first pivot located on the first steering support. A secondary steering wheel is mounted at an intermediate position on the auxiliary skating board and is connected to the auxiliary skating board by a second steering support and a second pivot located on the second steering support. The first and second steering supports are fixedly connected by the cross beam, and the auxiliary skating board can rotate with respect to the main skating board using the first pivot as the rotation center.
