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.
