Problems solved by technology
[0002] In the rotary compressor in the related art, in a low temperature environment, due to the decrease of the refrigerant evaporation temperature, the capacity of the refrigeration cycle system is reduced, and the performance of the rotary compressor is poor.
For this reason, some double-cylinder air-injection enthalpy-increasing compressors have appeared. However, when the compression load is small, the two-cylinder air-injection enthalpy-increasing compressors are still in the dual-cylinder operation mode, resulting in poor operating efficiency of the compressor.

The invention discloses a rotating type compressor and a heat exchange system with the same. The rotating type compressor comprises a liquid storage device, a shell, a compression mechanism, a one-way valve, a gas spraying pipe and a switching device. The compressor is provided with a first gas sucking opening and a second gas sucking opening. The one-way valve is connected between the liquid storage device and the second gas sucking opening and is communicated in one direction from the liquid storage device to the second gas sucking opening. The switching device is provided with a first valve opening, a third valve opening and a second valve opening which is selectively communicated with one of the first valve opening and the third valve opening. The first valve opening is communicated with the liquid storage device, the second valve opening is communicated with a second sliding piece groove, and the third valve opening is communicated with a discharging opening. When the switching device is in a full-load state, the second valve opening is communicated with the third valve opening. When the switching device is in a partial-load state, the second valve opening is communicated with the first valve opening. According to the rotating type compressor in the embodiment, the operation efficiency is high, the application range is wide, and the safety performance is high.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a rotary compressor and a heat exchange system with the rotary compressor. Background technique [0002] In the rotary compressor in the related art, in a low-temperature environment, the capacity of the refrigeration cycle system is reduced due to the decrease of the evaporation temperature of the refrigerant, and the performance of the rotary compressor is poor. For this reason, some double-cylinder air-injection enthalpy-increasing compressors have appeared. However, when the compression load is small, the two-cylinder air-injection enthalpy-increasing compressors are still in the dual-cylinder operation mode, resulting in poor operating efficiency of the compressor. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. Therefore, the present invention propo...
