Design regulations of blower-exhaust system in CNECC Standard
The design regulations of blower-exhaust system in CNECC Standard are formulated in accordance with the principle of rational utilization of energy, reduction of pollutant emission and improvement of indoor hygienic condition. These regulations include equipment selection, inspection and maintenance of blower-exhaust system, layout and design, energy conservation, noise control, electrical safety and so on.
Equipment selection: In the selection of equipment, it is necessary to select the one with high energy efficiency. In addition, the size and speed of the blower should be in line with the applicable conditions, according to the airflow needs and space requirements.
Inspection and maintenance: When blower-exhaust system is installed, it is necessary to carry out inspection and maintenance regularly. The system should be cleaned and checked regularly to ensure that the system can work well and effectively.
Layout and design: In the layout and design of the system, it should take into account the characteristics of the space, the amount of air flow, the location of air supply, air exhaust and air return, the consideration of sound insulation in ducts, etc.
Energy conservation: The system should be designed to optimize the use of energy when coupled with the control system. Such as using fans with high efficiency, adding speed regulating devices, using pressure reducing devices, using insulation materials and other energy saving measures.
Noise Control: During the operation of the system, noise should be minimized and indoor environment should be enough quiet. In the design, equipped with noise isolation devices, sound absorption and other measures to reduce the noise.
Electrical Safety:System wiring should be installed in accordance with national regulations and requirements for electrical safety, and should provide sufficient insulation, grounding and other considerations, so as to ensure the safety and reliability of the system.
In summary, the design regulations of blower-exhaust system in CNECC Standard include the selection of equipment, inspection and maintenance, layout and design, energy conservation, noise control, electrical safety and other contents. The design should observe the applicable requirements and ensure the rationality, safety and performance of the system.
