Disclosed is a rotating cylinder enthalpy-adding piston compressor. The compressor is a two-stage rotating cylinder piston compressor, including a first-stage rotating gas cylinder, a first gas cylinder liner, a first piston, and a second-stage rotating gas cylinder, a second gas cylinder liner, and a second piston, and further including an enthalpy-adding assembly connected between the first-stage rotating gas cylinder and the second-stage rotating gas cylinder for supplying gas and adding enthalpy between the two stages of rotating cylinders. By means of adopting a two-stage rotating cylinder piston compressor and arranging an enthalpy-adding assembly between the two stages of rotating cylinders, an enthalpy-adding function is achieved for the rotating cylinder piston compressor and the air conditioning system having same, thereby increasing the enthalpy value of the refrigerant in the system, improving the refrigerating and heating capabilities, improving the energy efficiency ratio and enhancing the reliability of the system.

Rotating cylinder enthalpy-adding piston compressor and air conditioning system having same

A compressor pump structure comprises a rotating shaft, a piston, a cylinder, a cylinder sleeve, a lower flange and an upper flange, the central axis of the rotating shaft being arranged eccentrically with respect to the central axis of the cylinder, the rotating shaft being slidably arranged in the piston, the piston being movably arranged in the cylinder and forming two volume-variable chambers with the cylinder, the piston comprising two first sliding planes arranged opposite one another and two first contacting planes arranged opposite one another, the first contacting plane on the upper side being in sealing contact with the upper flange, and the first contacting plane on the lower side being in sealing contact with the lower flange. Also disclosed is a compressor with the compressor pump structure.

Compressor pump structure and compressor

A fluid machine, heat exchanger, and operating method of fluid machine. The fluid machine includes: a rotation shaft (), a cylinder (), and a piston assembly (). The rotation shaft () and the cylinder () are eccentrically disposed relative to each other and an eccentric distance is fixed. The piston assembly () has a variable volume chamber (). Because the eccentric distance between the rotation shaft () and the cylinder () is fixed, the rotation shaft () and the cylinder () rotate about their respective axes thereof during motion and the position of center of mass remains unchanged, so that the piston assembly () is allowed to rotate stably and continuously when moving in the cylinder (); and vibration of the fluid machine is mitigated, a regular pattern for changes in the volume of the variable volume cavity is ensured.

Fluid machinery, heat exchange equipment, and operating method for fluid machinery

A compressor pump structure has a cylinder sleeve provided between an upper flange and a lower flange; a cylinder is provided inside the cylinder sleeve; a piston is slidably arranged inside the cylinder; a volume-variable chamber is formed among the cylinder sleeve, the cylinder and the piston; a rotating shaft passes through the piston, the axis of the rotating shaft being eccentrically disposed with respect to the axis of the cylinder with a fixed eccentricity; the rotating shaft drives the piston and the cylinder to rotate; and the piston slides within the cylinder while rotating so as to change the volume of the volume-variable chamber. Further disclosed is a compressor which comprises a compressor pump structure.
