A circulation system for improving the efficiency of a refrigeration compressor, referred to as a cold cylinder compression cycle. The compression cycle of cold compressor of rotor compressor is mainly realized in 4 aspects. A.: in the cold cylinder compression compression cylinder wall strong exothermic (defined as the hot cylinder, the cold cylinder) implementation of cryogenic cooling, tongue and rolling rotor surface coated with thermal insulation ceramics will be cooled to the hot cylinder compressing, increasing the heat cylinder area or reduce the speed, in order to fully eliminate and suppress overheated exhaust put form compression the lower the net work compression and condensation load. B. cold cylinder suction: the high pressure exhaust and the cold and hot cylinder and the upper and lower cover and the suction tube are separated by gas and heat insulation. The low temperature characteristics of the suction chamber are guaranteed by continuous suction and hot cylinder cooling to obtain larger cooling capacity. C. improved oil circuit: increasing suction suction. D. recycling exhaust heat and motor heat release: for heating and concentration of absorbent lubricating oil, absorbent in the cooling cylinder surface pressure is low, strong absorption, and further increase the cold and reduce compression work.
