An offshore nuclear power platform reactor compartment refrigeration system

Abstract

The invention discloses a reactor cabin refrigeration system of an offshore nuclear power platform, comprising a refrigerant water loop, a seawater loop and water. Water plate heat exchanger; The refrigerant water circuit comprises a first air conditioning water chiller unit, a first circulating water pump and a cooling area connected in sequence through a first pipeline; The first circulating water pump is used for delivering the refrigerant water in the first air conditioning chiller to the zone to be cooled, and the first pipeline is controllably connected with the fresh water source flow rate; The seawater circuit includes a seawater source connected to the first air conditioning chiller through a second pipeline. The water plate heat exchanger is respectively connected with the sea water source and the first pipe through the third pipe line and the fourth pipe line and forms a loop, and the first circulating pump is also used for transferring water to the sea water source and thefirst pipe line. The refrigerant water in the water plate heat exchanger is transported to the zone to be cooled. A first air conditioning water chiller is used for refrigeration in spring, summer andautumn, and water is used in winter. The water plate heat exchanger is used for refrigerating, and the reactor cabine re not only is safe and stable, but also can improve the system efficiency and reduce the economic cost.

Description

technical field [0001] The invention relates to the technical field of nuclear power platform reactor compartment refrigeration, in particular to a reactor compartment refrigeration system of an offshore nuclear power platform. Background technique [0002] Most marine air conditioners use centralized cooling and heating, and the refrigerant water mostly uses variable flow, which can provide a comfortable environment for the crew to live and work. The offshore nuclear power platform relies on nuclear energy to generate electricity. The nuclear reactor is arranged in the containment of the reactor cabin. When cooling, the reliability of the air conditioning system is highly required. In winter, since the air-conditioning load of the reactor compartment is only about half of that in summer, the operation of the refrigeration unit at about 50% of the energy level will easily lead to low system operation efficiency and excessive energy consumption, and it may be because the comp...
