Air conditioner

The utility model relates to a novel air conditioner for a universal device, belonging to the field of air adjustment. A compressor and a capillary pipe which are arranged in a coolant circulating system are respectively connected with a high voltage component and a low voltage component which are arranged in the coolant circulating system. A controlled electromagnetic valve is arranged between the high voltage component and the low voltage component. The utility model solves the problems that the air conditioner in the prior art is difficult to start with medium voltage, and the air displacement of the compressor in the prior art is enlarged to make starting current too large. When the compressor of the utility model starts, high voltage and low voltage are of short circuit; therefore, the compressor consumes low power, current to be needed is small, and the utility model can favorably start when voltage is lower than 180V.
