Electromagnetic Shielding Room Composition System

Air conditioning system: The air conditioning system in the shielded room can be configured according to the actual situation. When there is a central air conditioner, it can be directly connected through the waveguide window or installed separately. Civil air conditioners, commercial air conditioners, and precision air conditioners can all be selected, and the air conditioning power lines, internal and external control signal lines, and air hoses must be shielded accordingly.
Fire alarm system: The electromagnetic shielding room should be equipped with a fire alarm and sprinkler system. The alarm signal line and related control signals should also be filtered separately. Generally, one smoke alarm signal is configured.
Grounding system: Due to certain leakage of the shell during operation (related to the working characteristics of the filter), the grounding requirements for the protective room are extremely high. Single point grounding is required, related to geological factors, with a grounding resistance of ≤ 1 Ω.
Power supply system: The power supply for the shielded room is generally configured with equipment power supply and auxiliary power supply for air conditioning and lighting as needed. Due to certain leakage from the casing during operation, the power supply in the protective room cannot pass through the leakage protector.
Isolation: The communication element rooms of civil air defense and national defense command posts all involve isolation engineering, which has a close cross construction relationship with electromagnetic pulse protection rooms. Isolation is divided into standard isolation and simple isolation. The former has a complex process and high cost, and the simple isolation is composed of a yellow sand layer and a concrete layer.
Air inlet and exhaust ducts: The electromagnetic pulse protection room should be connected to the air inlet and exhaust ducts, and they should not be installed until they are laid in place.
