1. Exhaust lampblack and waste gas

排煙設(shè)備捕捉并排除廚房設(shè)備產(chǎn)生的全部油煙、蒸汽、廢氣，保證油煙熱氣不外溢，帶走部分廚房設(shè)備產(chǎn)生的多余熱童。

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、合理補充新風

2. Reasonably supplement fresh air

根據(jù)廚房自然補風量、空調(diào)新風量，通盤考慮送風機的新風量。使補充新風與排煙風量匹配，以平衡排煙產(chǎn)生的負壓，使廚房內(nèi)略有負壓，保證即使在冬天關(guān)閉室外門窗的情況下，當廚房門開啟時，流向廚房內(nèi)有不大于3111/8的風速。

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、控制溫度

3. Control temperature

根據(jù)廚房的工作環(huán)境要求標準，系統(tǒng)具有室內(nèi)溫度調(diào)節(jié)的功能，各種不同的工作間可按實際需要控制室溫。

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、新風凈化

4. Fresh air purification

補充的新風應(yīng)該進行凈化與調(diào)溫處理，防止灰塵雜物混人廚房，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、凈化油煙噪音

5. Purify lampblack and eliminate noise

排出的油煙應(yīng)該進行凈化處理，噪音，減少對環(huán)境的污染。

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

6、優(yōu)化設(shè)計降耗

6. Optimize the design to save energy and reduce consumption

通過系統(tǒng)計算，要對系統(tǒng)流量、壓力、熱量等技術(shù)指標，進行平衡優(yōu)化設(shè)計，使系統(tǒng)通風機工作在工況點上。采用分散控制、系統(tǒng)動態(tài)平衡設(shè)計，使系統(tǒng)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.
