How to Design the Kitchen Smoke Exhaust Ventilation System?

The design principles of the kitchen smoke exhaust ventilation system are matters that need to be paid attention to in the specific design. In the following, only the problems related to the structural coordination design of the airflow flow, pipeline orientation and system control of the system design will be described.

Implement system engineering design

System engineering design is undoubtedly the higher goal of smoke exhaust ventilation system design technology. The implementation of kitchen smoke exhaust ventilation system engineering design includes two major tasks: air volume balance calculation and structural coordination design.

Air Volume Balance Calculation

The fluidity of the gas has the characteristics of automatic balance and distribution. The air volume balance calculation is calculated and designed by considering the common room and the space connected with the kitchen as a whole. Air volume balance calculation includes the following contents.

Connected space: Calculate the airflow of each working space in the kitchen and the space connected with the kitchen as a whole system.

Related system: Calculate the exhaust system and fresh air system, natural supplementary air, ventilation, air conditioning, fire protection, etc. as a whole system to improve the overall coordination performance of the system.

Air flow flow: Calculation design with clear flow direction and flow control for air flow flow.

High efficiency and energy saving: use system engineering thinking to carry out economic calculations, and under the premise of ensuring the effect of smoke exhaust and ventilation, make full use of the air conditioning system, various airflows in the surrounding environment, and the energy in the airflow to achieve high-efficiency and energy-saving system design.

Inter-system coordination design

The equipment components of the smoke exhaust ventilation system not only need the support of the hydropower system, but also need to coordinate the space installation relationship with the building structure and other systems.

Spatial structure: According to the air volume calculation results, design the pipe size, direction, inlet and outlet, oil fume purifier, fan selection, etc., and combine the structural space to coordinate the relationship between the air conditioning system, fire protection system, cable tray, installation location and the surrounding environment, ingeniously Use the space to complete the design of the configuration of all components of the system.

Coordination of water and electricity: the system needs water and electricity, and the specific contact position, space occupation, and management must be considered in the system design

line direction etc.

Airflow design

Combined with the kitchen structure and environment, according to the requirements of cleanliness, temperature and humidity, etc., design the flow process of fresh air, air-conditioning air, and natural air between the kitchen and the dining room, design the air flow process, and draw an air flow organization diagram when necessary.
