Energy-saving type rolling rotor compressor

Abstract

The invention relates to an energy-saving type rolling rotor compressor. The energy-saving type rolling rotor compressor is characterized in that a shell of the compressor is internally and axially provided with a crank shaft; one side of the crank shaft is provided with a motor, and the other side of the crank shaft is provided with an upper cylinder cover, a piston and a lower cylinder cover in sequence; a steam cylinder is sheathed outside the piston and is ring-shaped, and bumps are arranged at the periphery of one side of the steam cylinder; the bumps are respectively provided with gas suction ports and blade grooves which are radially communicated with the steam cylinder; blades in the blade grooves are contacted with the outer circumference of the piston; a heat exchange groove is arranged on the end surface of the steam cylinder corresponding to the upper cylinder cover; one end of the heat exchange groove is communicated with the gas suction ports, and the other end of the heat exchange groove is communicated with a drainage pipe; and the other end of the drainage pipe extends out of the shell. In the energy-saving type rolling rotor compressor, the drainage heat exchange groove is arranged on a steam cylinder body, and a liquid refrigerant from a refrigerating system in the groove exchanges heat with the steam cylinder body, so that the temperature of the wall surface of the steam cylinder is reduced, the heat produced by the gas compression process in the cylinder is removed, and the working process of the compressor is forced to change towards an isothermal mode. In the energy-saving type rolling rotor compressor, the consumed power of the compressor is effectively reduced, the exhaust temperature is reduced and the high-efficiency and energy-saving operation is realized.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a rolling rotor compressor. Background technique [0002] The compressor is the core component of the refrigeration and air conditioning system, and its effective energy-saving operation is of great significance to the effective utilization of energy in the system. According to the theory of thermodynamics, the working fluid in the compressor consumes the most power for isentropic compression, the least power for isothermal compression, and the power consumed by variable compression (1<n<k) is between the two. From the perspective of reducing the energy consumption of refrigeration compressors, the best refrigerant solution is to use isothermal compression. Because the heat generated by the refrigerant gas in the compression process cannot be dissipated in time, the actual working process of the existing refrigeration compressor is close to isentropic, the compressor c...

Problems solved by technology

In the prior art, there is a cooling method in which a hole is opened in the cylinder head and liquid refrigerant is directly sprayed into the cylinder to carry out the cylinder compression process. However, in the implementation process of this type of solution, there is a risk of liquid shock inside the compressor due to excessive liquid injection.
