1. control a method for the mass flowrate of positive discharge capacity decompressor, comprising:

  • Working fluid is pumped into heat exchanger to convert described fluid to working steam;

    Be stored in accumulator at least partially by described working steam, described accumulator is connected to described heat exchanger;

    AndVia pulse width modulation valve the working steam of described storage is optionally discharged into positive discharge capacity decompressor at least partially to improve the efficiency of described decompressor.
