Abstract:
Provided are a gas-replenishing and enthalpy-increasing control method, device and apparatus for a two-stage compressor. The method includes: when a gas-replenishing electronic expansion valve needs to be opened, gradually increasing, by a controller, an opening degree of the gas-replenishing electronic expansion valve in a time sequence; after the gas-replenishing electronic expansion valve is opened, acquiring a detected gas-replenishing superheat degree of a two-stage compressor; and adjusting, based on the gas-replenishing superheat degree of the two-stage compressor, the opening degree of the gas-replenishing electronic expansion valve, wherein the gas-replenishing electronic expansion valve is disposed between a medium-pressure liquid storage tank and the two-stage compressor, and when the opening degree of the gas-replenishing electronic expansion valve is not zero, a gaseous refrigerant in the medium-pressure liquid storage tank replenishes gas and increases enthalpy for the two-stage compressor,.

Claim (Index 17):
The apparatus as claimed in  claim 13 , wherein the acquisition unit comprises:\n a collection module, configured to collect a gas-replenishing temperature and a gas-replenishing pressure of the two-stage compressor; an acquisition module, configured to acquire a saturation temperature corresponding to the gas-replenishing pressure; and a calculation module, configured to take a difference between the gas-replenishing temperature and the saturation temperature as the gas-replenishing superheat degree of the two-stage compressor.
