The invention discloses an electric compressor. The electric compressor comprises a plurality of shells arranged in parallel, wherein bearing sets are arranged at the ends of the shells; male screws and female screws are arranged in the shells and connected with the bearing sets, and driving motors are arranged on the outer sides of the bearing sets and connected with the male screws; oil tanks are arranged in the shells, exhaust ports of the shells are connected with oil separators, and the oil separators are connected with the oil tanks through first oil return pipes; oil level sensors are arranged in the oil tanks; the oil tanks are connected with oil supply pumps through first oil injection pipes, and first electric control valves are arranged on the first oil injection pipes; the oil supply pumps are connected with oil storage tanks, and the oil tank are connected with the oil storage tanks through second oil return pipes; and second electric control valves are arranged on the second oil return pipes. The defects in the prior art can be overcome, the problem of oil shortage caused by frequent starting and stopping of the compressor is solved, and the control precision of a refrigerating system on the temperature of a controlled object is improved.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an electric compressor and a control method thereof. Background technique [0002] The compressor is the core equipment of the refrigeration system. During the operation of the compressor, the refrigerating oil utilizes the pressure generated by the compressor to achieve circulating moisturizing and cooling. Since the refrigeration oil in the compressor will be discharged from the compressor together with the refrigerant, in order to ensure sufficient refrigeration oil in the compressor, in the prior art, the refrigeration oil in the discharged refrigerant is separated by an oil separator and returned to the compressor Inside. Since the oil separator needs a continuous working pressure to work normally, when the compressor starts and stops frequently, the working pressure cannot be maintained, which will cause the oil return rate of the oil separator to drop or e...
