Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0023] like figure 1 As shown in the figure, the present invention provides a ventilation system for improving the distribution of fresh air volume in the personnel room by the emergency command center of the nuclear power plant, including the maintenance of positive pressure fresh air subsystem and the personnel fresh air subsystem; the air supply port of the personnel room 4 and the equipment room 3 The air supply ports of 4 are connected to the air outlet end of the positive pressure fresh air subsystem; the fresh air outlet of the personnel room 4 is connected to the air outlet end of the personnel fresh air subsystem.
[0024] The ventilation system of the present invention further includes a filtration system for nuclear power plant accidents; the air inlet end of the positive pressure fresh air subsystem and the air inlet end of the personnel fre...

The invention relates to a ventilation system for the emergency command center of a nuclear power plant to improve the distribution of fresh air in personnel rooms, including a sub-system for maintaining positive pressure fresh air and a sub-system for personnel fresh air; the air inlets of the personnel rooms and the air inlets of the equipment rooms are connected to The air outlet of the maintaining positive pressure fresh air subsystem; the fresh air outlet of the personnel room is connected to the air outlet of the personnel fresh air subsystem. The beneficial effects of the present invention are as follows: the fresh air volume is redistributed through the two subsystems, and in the case of a serious accident in a nuclear power plant, the optimal distribution of the fresh air allowed to enter the emergency command center can be realized, and the maximum degree can be achieved under the limited fresh air volume. Improve the comfort of the indoor personnel room, improve the ambient air quality, and maintain the slight positive pressure of the emergency command center relative to the outdoor environment.
Description
technical field [0001] The invention belongs to the technical field of ventilation for special emergency response facilities in nuclear power plants, and particularly relates to a ventilation system for improving the distribution of fresh air volume in personnel rooms for emergency command centers of nuclear power plants. Background technique [0002] The air-conditioning room of the emergency command center is divided into equipment room and personnel room. The former is characterized by concentrated process equipment but no personnel staying for a long time, large indoor heat generation and high air conditioning cooling load, while the latter is characterized by concentrated work of personnel and less process equipment. The indoor calorific value is small, the cooling load of the air conditioner is low, but the demand for fresh air is high. From the nuclear power plants that have been built and are in active service in China (Ling'ao Nuclear Power Plant Phase II Project, Q...
