Compressor and heat pump system with the compressor

Abstract

The invention provides a compressor and a heat pump system with the compressor. The compressor comprises a compressor body and an enthalpy increasing apparatus. The compressor body comprises a low pressure compression part and a high pressure compression part and is provided with an air inlet, an enthalpy increasing port and an air outlet; the compressor body is further provided with a medium pressure chamber, and a low pressure compression chamber and a high pressure compression chamber respectively connected with the medium pressure chamber; the low pressure compression part comprises a low pressure cylinder and the low pressure compression chamber, and a high pressure compression part comprises a high pressure cylinder and the high pressure compression chamber. The enthalpy increasing apparatus comprises an accommodation device and an enthalpy increasing pipe, wherein the accommodation device is communicated with the enthalpy increasing port through the enthalpy increasing pipe, a ratio of the volume of the accommodation device to the working volume of the low pressure cylinder is k1, and k1 is no less than 1 and no more than 5. With the compressor provided by the invention, the purposes of decrease of noise and reduction in vibration of the compressor during operation are achieved by controlling the range of the ratio of the volume of the accommodation device to the working volume of the low pressure cylinder.

Description

technical field [0001] The invention relates to the field of temperature regulation, in particular to a compressor and a heat pump system with the compressor. Background technique [0002] In the prior art, the dual-rotor two-stage enthalpy-increasing compressor has relatively large noise due to large air flow pulsation, and the enthalpy-increasing device of the compressor cannot effectively buffer the fluid pulsation. Moreover, the enthalpy increasing device in the prior art is equivalent to a cantilever beam structure, without a connection structure fixed with the shell, with low natural frequency and relatively large vibration. Especially in the middle and low frequency operation, the noise and vibration of the compressor are particularly obvious. Contents of the invention [0003] The present invention aims to provide a compressor and a heat pump system with the compressor, so as to achieve the purpose of reducing noise and vibration during operation. [0004] In ord...
