1. Exhaust lampblack and waste gas

国产精品伦一区二区三级视频设备捕捉并排除厨房设备产生的全部油烟、蒸汽、废气，保证油烟热气不外溢，带走部分厨房设备产生的多余热童。

Smoke exhaust equipment captures and removes all lampblack, steam and waste gas generated by kitchen equipment to ensure that lampblack and hot gas do not spill out and take away excess hot children generated by some kitchen equipment.

2、合理补充新风

2. Reasonably supplement fresh air

根据厨房自然补风量、空调新风量，通盘考虑送风机的新风量。使补充新风与国产精品伦一区二区三级视频风量匹配，以平衡国产精品伦一区二区三级视频产生的负压，使厨房内略有负压，保证即使在冬天关闭室外门窗的情况下，当厨房门开启时，流向厨房内有不大于3111/8的风速。

According to the natural make-up air volume of the kitchen and the fresh air volume of the air conditioner, the fresh air volume of the forced draft fan shall be considered comprehensively. Make the make-up fresh air and smoke exhaust air volume match to balance the negative pressure generated by smoke exhaust, so that there is a slight negative pressure in the kitchen, and ensure that even when the outdoor doors and windows are closed in winter, when the kitchen door is opened, there is no more than 3111/8 wind speed flowing into the kitchen.

3、控制温度

3. Control temperature

根据厨房的工作环境要求标准，系统具有室内温度调节的功能，各种不同的工作间可按实际需要控制室温。

According to the working environment requirements of the kitchen, the system has the function of indoor temperature regulation, and various workplaces can control the room temperature according to actual needs.

4、新风净化

4. Fresh air purification

补充的新风应该进行净化与调温处理，防止灰尘杂物混人厨房，污染食物。

The supplemented fresh air shall be purified and temperature regulated to prevent dust and sundries from mixing into the kitchen and polluting food.

5、净化油烟噪音

5. Purify lampblack and eliminate noise

排出的油烟应该进行净化处理，噪音，减少对环境的污染。

The lampblack discharged shall be purified to eliminate noise and reduce environmental pollution.

6、优化设计降耗

6. Optimize the design to save energy and reduce consumption

通过系统计算，要对系统流量、压力、热量等技术指标，进行平衡优化设计，使系统通风机工作在工况点上。采用分散控制、系统动态平衡设计，使系统具有降耗的功能。

Through system calculation, balance optimization design shall be carried out for system flow, pressure, heat and other technical indicators to make the system ventilator work at the optimal working point. Decentralized control and system dynamic balance design are adopted to enable the system to save energy and reduce consumption.
