Do hotel decoration fan rooms need drainage ditches?

1. The entrance and installation holes of the computer room. The machine room should be equipped with two non-adjacent entrances and exits, especially the ammonia refrigeration machine room should be equipped with two entrances and exits as far away from each other as possible. At least one of them should be directly facing the outside, and the doors and windows of the machine room should be opened outwards. .

The computer room should reserve entrances and exits or installation holes that can pass the largest piece of equipment. When it is not possible to directly use outdoor hoisting machinery to hoist equipment, hooks or lifting equipment that can lift the largest components should be reserved on the beam above the hoisting hole.

2. Transport channel. In order to facilitate the replacement of various equipment in the computer room, the computer room should have a transportation channel suitable for the largest equipment or components; if there are real difficulties, some easily disassembled pipes and components can be properly removed.

3. The computer room should have good ventilation facilities:

①Normal ventilation. The refrigeration machine room should be equipped with ventilation facilities. Ventilation is to meet the requirements of eliminating indoor residual heat and ensuring that operators have sufficient fresh air;

②Accident ventilation. Accident exhaust facilities must be installed in the refrigeration machine room to ensure safe production and ensure the safety of workers, especially the ammonia refrigeration machine room.

In order to simplify the design and reduce equipment investment, one fan is often used for daily ventilation and emergency ventilation. Use two-speed or variable-speed fans to meet the requirements of different air volumes;

4. Fire protection requirements for ammonia refrigeration equipment rooms. Ammonia vapor and air become a flammable and explosive gas when the mixture reaches a certain ratio.

The fire protection requirements of the ammonia compressor room should comply with the fire hazard Class B production in the current "Code for Fire Protection Design of Buildings" Relevant regulations for factory buildings.

5. Equipment layout space in the computer room. The equipment layout in the machine room should be convenient for operation, and there should be appropriate maintenance space.

The well should be as compact as possible to save the use area.
