The kitchen of the general hotel, even the kitchen of many four or five -star hotels, did not design air -conditioning to cool down, so everyone can see the chefs work like rain. In the hotel kitchen with a low grade, the staff even played in Chibi. When there is a little free, the kitchen door is open. Guests often see several kitchen staff at the door secretly enjoying the air -conditioning of the restaurant.

This is the status quo of the hotel kitchen, and the hardships of the kitchen staff can be imagined. Of course, a few more particular hotel kitchen will install air ducts for job cold, but it can be imagined that a dozen degrees of wind hit the staff’s head. The wet kitchen air will inevitably be inevitable that the knot and water drop of the outlet of the air outlet may have affected the hygiene of food.

Of course, the hotel operator is not regardless of the harsh environment of staff, but it is more to help, because the traditional compressed air conditioner is really difficult to solve the problem of ventilation and cooling of the kitchen. The reasons are as follows:

1. The air conditioners used in the kitchen cannot be used in the air conditioner. If the split air conditioner or the central air conditioner is used in the kitchen, it must not inhale the kitchen air. Otherwise, the oil fume in the kitchen will erode the internal fins and electrical components of the air conditioner in a short period of time, causing the air conditioning damage and hygiene problems.

2. All use the refrigeration of fresh wind through refrigeration. In addition to the precise wind and exposed problems mentioned above, it will cause a great loss of cold, and electricity costs will increase.

Cold fan principle

The principle of refrigerator and compressor air conditioners such as traditional split air conditioners and central air conditioners is completely different. It uses water to evaporate the principle of heat absorption. When a large amount of outdoor air is inhaled by the air conditioner, flowing through the surface of the wet curtain, the water in the wet curtain has evaporated a large amount of water, which reduces the temperature. This kind of air that is cooled and filtering is blown on the person to make people feel fresh and cool.

Cold fan costs are only 30%to 50%of traditional compressor air conditioners; power consumption is only 10%to 15%of the compressed air conditioner; good air quality, new wind supply, replace indoor air again in 1 to 2 minutes. Based on these three major characteristics, the use of refrigerator has become more and more common, especially suitable for most factories, restaurants, business venues, open -air places, kitchen, etc.

However, due to the limited cooling of the cold fan, when the general summer climate temperature in the south is 36 ° C and the humidity is 50%, the temperature of the cold air machine is about 28 ~ 29 ° C. This temperature must be used with electric shutters at the same time, or with hanging fans, wall fans, etc. In a word, people must have wind blowing at 28 ~ 30 ° C to ensure comfort. In fact, the vast majority of people are accustomed to opening a fan in the office or family at 28 ~ 32 ° C to meet the basic comfort requirements.

As shown in the figure, a typical hotel kitchen is provided with exhaust design drawings. Generally, such places are very large to send exhaust air volume to effectively discharge the kitchen hot and humid and oil fume.
The modification project is very simple. Just according to the air volume and wind pressure of the original fan, and then choose the appropriate hanging environmental air conditioning model to replace the original air conditioner environmental protection water conditioner, supply a tap water pipe to the air conditioner. At the same time, a drainage pipe is connected to the floor drain, which can be used after connecting the power.
After the modification, the air supply is still 100%new, but the air out of the air is the cool air after the cooling. The average temperature of the kitchen is greatly reduced. At the same time, adjust the direction of the outlet as much as possible so that the staff can blow the wind.
