1. varying capacity, unsteady flow amount (VRWV) air-conditioning system, comprise the also gang air conditioner that contains a variable conpacitance compressor cooling-water machine (6) and other fixed cooling-water machines (7) frequently at least, flow-changing water pumping system (8), the pipeline of fan coil group (9) and corresponding connection, the control system of the regulating system refrigerating/heating amount and the water yield (1)-(5), it is characterized in that:

  • 1) wherein and gang air conditioner comprise and contain a variable conpacitance compressor cooling-water machine (6) at least, each cooling-water machine all contains the startup of an electromagnetism two-way valve (10) control current, the stack successively of several compressors in the system starts the energy output provide whole, and minimum unit or be in the stepless energy adjustment of single invariable frequency compressor energy mid portion energy by variable conpacitance compressor;

         2) the flow-changing water pumping system comprises at least one at least one flow sensor of varying capacity water pump (11), differential-pressure bypass valve (12);

         3) control system of the regulating system refrigerating/heating amount and the water yield comprises fan coil controller (5), cooling-water machine controller (4), unsteady flow amount controller (2), middle controller (3), master controller (1), the data message that former three is gathered all passes through middle controller (3) or direct and master controller (1) communication, master controller (1) receives data, calculate the back to fan coil controller (5), cooling-water machine controller (4), unsteady flow amount controller (2) transmission information, these controllers are to the electromagnetism two-way valve (10) of correspondence, water pump, differential-pressure bypass valve (12), compressor, the compressor variable frequency device transmits control signal.4) each fan coil (9) system all have electromagnetism two-way valve (10) and can with the fan coil controller (5) of master controller (1) or middle controller (3) communication.
