Machine Room Site Selection


The machine room should be at least 5 km (3.11 miles) away from heavy pollution sources, such as the
smelter works, coal mine, and thermal power plant. The machine room should be at least 3.7 km (2.30 miles)
away from medium pollution sources, such as the chemical factory, rubber factory, and electroplating factory.
The machine room should be at least 2 km (1.24 miles) away from light pollution sources, such as the food
factory and leather plant. If the pollution source is unavoidable, the machine room should be located on the
windward side of the pollution source perennially with advanced protection.

The machine room should be at least 3.7 km (2.30 miles) away from the sea or salt lake. Otherwise, the
machine room must be sealed, with air conditioner installed for temperature control. Saline soil cannot be
used for construction. Otherwise, you should select devices with advanced protection against severe
environment.

Do not build the machine room in the proximity of livestock farms. Otherwise, the machine room should be
located on the windward side of the pollution source perennially. The previous livestock house or fertilizer
warehouse cannot be used as the machine room.

The machine room should be firm enough to withstand severe weather conditions such as windstorm and
heavy rain as well as away from dust. If the dust is unavoidable, keep the door and window away from the
pollution source.

The machine room should be away from the residential area. Otherwise, the machine room should meet the
construction standard in terms of noise.
