Auto Defrost EVI Low Temperature Heat Pump 16A For Hotel

control method for a low-temperature heat pump system is adopted, which includes the following steps: A. Turn on the compressor, and after the main circuit runs for t1 until the refrigerant operation within it is almost steady, run the jet enthalpy increase circuit; B. Judging the heating process Whether the exhaust temperature T row is greater than the preset maximum exhaust temperature T row max, if yes, go to step C, otherwise, go to step E; C. Inject the supercooled refrigerant liquid directly into the middle pressure cavity of the compressor to reduce the discharge Air temperature T row; D. Determine whether the exhaust temperature T row is greater than the preset maximum exhaust temperature T row max-the return difference value △T row of exhaust temperature drop, if yes, go to step C, otherwise, go to step E; , The system is heated to the set temperature and exits. The invention solves the problem that the existing low-temperature heat pump system cannot reach a stable state as soon as possible in the early stage of operation, and the refrigerant distribution of the main circuit and the injection circuit may be uneven, and the reliability of the compressor is improved.
