Abstract: The present disclosure provides a control method of a compressor and a refrigerant circulation system. The control method includes deciding whether a current working volume state of the compressor is matched with a control instruction after the compressor completes a change to a working volume according to the control instruction; determining that the compressor operates normally in a case where the current working volume state of the compressor is matched with the control instruction; and determining that the compressor operates in fault in a case where the current working volume state of the compressor is not matched with the control instruction.

Abstract: A piston machine, in particular a fluid piston machine, is described as having a plurality of piston units, which have differently sized output volumes for reasons of geometry, and are able to be deactivated individually for the discrete adjustment of a total output volume of the piston machine. In this context, the larger output volume of one of the piston units is twice as high as the next smaller output volume of one of the other piston units.

Abstract: A pump which can operate in a number of different modes, wherein each mode corresponds to a different output of the pump. The pump may have a plurality of pump chambers located within a pump housing. The pump chambers may be arranged in fluid communication with an inlet port and an outlet port. Each pump chamber may have a pumping device which draws in fluid from the inlet port during an intake stroke and pushes fluid through the outlet port during a discharge stroke. The pump may also have a plurality of electronically controlled valve assemblies which control the output of the pump. Each valve assembly can be selectively switched to a by-pass state for by-passing the fluid flowing from the pump chamber back to the inlet port during the discharge stroke of a pumping device. The pump may operate in a number of different modes which each have a distinct output. Each mode may be defined by which valves are chosen to be switched to their by-pass state.
