The kitchen air conditioning system should not be used in fan coil systems, because the kitchen fumes, more water vapor, long cycle will inevitably cause indoor air hood attached to the surface of the coil, the heat transfer coefficient is greatly reduced, the cooling effect is getting worse, so as not to use.

廚房空調系統一般采用直流式空調系統，它所處理的空氣全部來自室外，不可用回風。

The kitchen air conditioning system usually adopts the direct current air conditioning system, which handles all the air from the outside and can not return the air.

廚房空調通風系統采用形式

Kitchen air conditioning ventilation system adopted form

廚房送風包括兩部分：室外新風和空調風。

The kitchen air supply consists of two parts: outdoor fresh air and air conditioning.

(1)室外新風。室外新風通過軸流或離心風機經風管送入靠近爐灶處．主要起到補風作用。新風位置要適當，送風切不能在廚師頭頂或頸后直吹，否則會造成不舒適，嚴重的會引起廚師職業(yè)病。送風口距廚師約1．5m較合適。

(1) outdoor fresh air. Outdoor fresh air through the axial or centrifugal fan through the air pipe into place. Next to the stove mainly to wind up effect. Fresh air position should be appropriate, air cut can not be in the chef's head or neck straight blowing, otherwise it will cause discomfort, and serious will cause cooks occupational diseases. The air outlet is about 1.5m suitable for the chef.

(2)空調風。空調風來源于新風機組或組合式空調器，通過風管送入遠離爐灶處，調節(jié)廚房內溫度，同時也起到補風作用。送風口可根據廚房具體情況合理布置。

(2) air conditioning. The air conditioning is derived from a new air unit or a combined air conditioner. It is sent into the kitchen away from the stove by the air duct, and the temperature in the kitchen is adjusted. The air outlet can be arranged reasonably according to the specific conditions of the kitchen.

(3)送風量的確定。為防止廚房氣味串人餐廳，廚房應保持負壓。一般情況下，廚房負壓值不得大于5Pa。送風量(新風+空調風)應按排風量的85%～95%考慮。

(3) determination of air supply volume. In order to prevent kitchen odour from mixing into restaurants, the kitchen should be kept under negative pressure. Under normal circumstances, the kitchen negative pressure shall not be greater than 5Pa. The air supply rate (fresh air + air conditioning wind) should be considered as 85% to 95% of the exhaust air volume.

(4)不論新風還是空調風，送風管均需設置防火閥，當溫度超過70℃時自動關閉，且與風機或空調機組聯鎖。

(4) no matter the fresh air or air conditioning, the air supply pipe shall be equipped with fireproof valve. When the temperature is over 70 degrees centigrade, it will be automatically closed and in
