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.
Claims20
A control method of a compressor, comprising:
- deciding whether a current state of a working volume of the compressor is matched with a control instruction after the compressor completes a change to the working volume according to the control instruction;
- determining that the compressor operates normally in a case where the current state of the working volume of the compressor is matched with the control instruction;
- and
- determining that the compressor operates in fault in a case where the current state of the working volume of the compressor is not matched with the control instruction,
- wherein the compressor has a plurality of cylinders and a control unit connected to the plurality of cylinders, wherein the control unit changes the working volume of the compressor by means of changing a number of cylinders operating among the plurality of cylinders, the compressor comprises two cylinders, and the control unit comprises a control valve.
A control method of a compressor, comprising:
- deciding whether a current state of a working volume of the compressor is matched with a control instruction after the compressor completes a change to the working volume according to the control instruction;
- determining that the compressor operates normally in a case where the current state of the working volume of the compressor is matched with the control instruction, and
- determining that the compressor operates in fault in a case cohere the current state of the working volume of the compressor is not matched with the control instruction, wherein the compressor comprises a compressor body and a driving controller connected to the compressor body, and the driving controller is connected to a control device that sends the control instruction,
- the control method further comprising:
- determining, by the control device, that the change to the working volume of the compressor is in fault, in a case where no change to the working volume of the compressor occurs throughout a process, during which the driving controller receives the control instruction and operates for a preset waiting time length.
A control method of a compressor, comprising:
- deciding whether a current state of a working volume of the compressor is matched with a control instruction after the compressor completes a change to the working volume according to the control instruction;
- determining that the compressor operates normally in a case where the current state of the working volume of the compressor is matched with the control instruction;
- and
- determining that the compressor operates in fault in a case where the current state of the working volume of the compressor is not matched with the control instruction,
- wherein the compressor comprises a compressor body and a driving controller connected to the compressor both, and deciding whether the current state of the working volume of the compressor is matched with the control instruction comprises:
- acquiring a parameter Y of the driving controller at a first preset time interval, storing the acquired parameter Y at a second preset time interval, and deciding whether the current state of the working volume of the compressor is matched with the control instruction according to the parameter Y, wherein the parameter Y of the driving controller comprises at least one of a current, a voltage or a power of the driving controller.
