对于设置集中空调系统的建筑来说，厨房的工作环境能够保证，聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 其补风多为有序送风，灵活性也较大，在目前厨房的通风系统中，多为以下三种补风方式：
For the buildings with central air conditioning system, the working environment of the kitchen can be guaranteed. The air supply is mostly orderly and flexible. In the current ventilation system of the kitchen, there are three ways of air supply
（1）餐厅空调为全新风直流式空调系统，空调新风首先送入餐厅，然后流入厨房经排风系统排出室外。此种方式投资较少，餐厅内采暖通风效果好。不足之处是大量空调风会被直接排出，新风能耗大，不利于节能。
(1) The restaurant air conditioner is a fresh air direct current air conditioning system. The fresh air of the air conditioner is first sent into the restaurant, and then flows into the kitchen and is discharged out of the room through the exhaust system. This way of investment is less, and the effect of heating and ventilation in the restaurant is good. The disadvantage is that a large number of air-conditioning air will be directly discharged, and the energy consumption of fresh air is large, which is not conducive to energy saving.
（2）将组合式空调机组的新风一部分直接补入厨房，一部分送入餐厅，并通过回风机回到空调机。这样可以部分解决新风能耗大的问题，同时使用的灵活性也较大。可在厨房设置测压装置，当厨房排风机全部工作时，负压增大，则回风电动阀关闭，回风机停，餐厅送风大量补入厨房；当少部分排风机开启或排风机不工作时，负压不是很大，则回风电动阀打开，回风机启动，避免空调送风全部被排出。
(2) Part of the fresh air of the combined air conditioning unit is directly fed into the kitchen, part is fed into the dining room, and returned to the air conditioner through the return fan. This can partly solve the problem of large energy consumption of fresh air, and at the same time, the use of flexibility is also greater. The pressure measuring device can be set in the kitchen. When all the exhaust fans in the kitchen work and the negative pressure increases, the return air electric valve will be closed, the return fan will stop, and a large amount of air will be supplied to the kitchen; When a small part of the exhaust fan is on or the exhaust fan is not working, if the negative pressure is not very large, the return air electric valve will be opened and the return fan will be started to avoid all the air supply of the air conditioner being discharged.
（3）用两台机组分别为餐厅、厨房服务，其中厨房为全新风直流系统，直接补充厨房炉灶的排风，而餐厅为一次回风全新空气系统，这个方案能保证餐厅和厨房的空调效果，而且厨房和餐厅系统互不干扰，缺点是初投资较大。
(3) Two units are used to serve the dining room and kitchen respectively. The kitchen is a fresh air direct current system to directly supplement the exhaust air of the kitchen stove, while the dining room is a fresh air system with primary return air. This scheme can ensure the air conditioning effect of the dining room and kitchen, and the kitchen and dining room systems do not interfere with each other. The disadvantage is that the initial investment is large.
