Temperature control method for machine room of large-scale supergravity centrifugal machine

The invention discloses a method for controlling the temperature of a machine room of a large-scale supergravity centrifugal machine, which comprises a refrigerating machine, a secondary refrigerant primary circulating pump, a secondary refrigerant circulating pump, a cooling tower, a cooling water pump and a heat exchanger. When the centrifugal machine operates under the working conditions of large overload and large heat production, the refrigerating machine can adapt by adjusting the refrigerating capacity, when the centrifugal machine produces heat when the centrifugal machine produces heat, the refrigerating machine can be closed, a refrigerating medium and cooling water are subjected to heat exchange through the heat exchanger, heat produced by the centrifugal machine is taken away, and then the temperature in a centrifugal machine chamber is adjusted. According to the method for controlling the temperature of the machine room of the large-scale supergravity centrifugal machine, the temperature of the h
