The national standard does not directly mention engine room temperature requirements. Only paragraph 6.3.5 of GB7588-2003 “Safety Code for the Manufacture and Installation of Elevators” mentions that “the machine room must have appropriate ventilation”. When receiving the elevator, if there is no exhaust fan, the department's reception staff may get stuck on you.
The technical instructions provided by the elevator manufacturer usually include requirements for the machine room temperature, which is usually between 5 and 40 degrees. In actual use, keeping the machine room temperature within the above range is beneficial to the stable operation and service life of the elevator.
I actually measured the temperature of a computer room without an exhaust fan or ventilation during high temperaturesin summer, and it exceeded 50 degrees. It's really bad for elevators.
Very few elevator rooms in areas south of the Yangtze River are equipped with air conditioners, but many are equipped with exhaust fans.
According to the information you provided, the local clearance height of the escape room is 1.8 meters. The exhaust engine room is designed to ensure air circulation in the engine room and exhaust pollutants. Local headroom indicates the height of a certain area in the computer room and is generally used to ensure the normal operation of machines and equipment.
However, it should be noted that the 1.8 meter headroom may not be sufficient to accommodate some larger machines and equipment. When designing the computer room, the local net height should be determined according to the actual situation. The requirementsExact headroom requirements are generally dictated by current safety regulations and design standards. For example, for some machines and equipment, a higher headroom may be necessary to ensure safe operation and maintenance.
Therefore, if you encounter any related issues during the construction or design of an exhaust room, it is recommended to consult a professional engineer or follow relevant codes and standards to ensure that safety and operational requirements are met.
