Abstract

The invention discloses a rotary compressor and a refrigeration cycle device with the same. The rotary compressor comprises a shell and a motor arranged in the shell, wherein the difference value of any two rotary speeds of the motor is delta R in a range of less than 40% of the maximum refrigeration capacity obtained during rotation of the motor; the difference value of the refrigeration capacities obtained by the two rotary speeds is taken as delta H; tan theta b of the rotary compressor is delta Hb / delta Rb; tan theta a of a rotary compressor in the prior art is delta Ha / delta Ra; Y is tan theta a / tan theta b; and the value of Y is 1.10-1.30. According to the rotary compressor disclosed by the embodiment of the invention, the discharge capacity is reduced and the running rotary speed range of the compressor is expanded, so that the compressor can be miniaturized, the slide loss can be reduced, and the cost can be lowered.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a rotary compressor and a refrigeration cycle device having the same. Background technique [0002] Through the use of frequency conversion motor, the rotation speed can be freely converted to control the cooling capacity of the frequency conversion rotary compressor, which does not need to switch the compressor as frequently as the fixed speed machine. Therefore, not only the APF (annual energy efficiency) can be improved, but also a stable room temperature can be maintained, and the comfort is also good, so the inverter rotary compressor has been popularized all over the world. Among them, APF = cooling period + capacity exerted during heating period (KWH) / power consumption (also known as power consumption) (KWH) during cooling period + heating period, thus determining the value of APF. [0003] Inverter rotary compressors are characterized by changes in compressor efficiency (C...
