Application and design of fresh air system in commercial kitchen equipment
What is the kitchen fresh air system?
The fresh air system is a set of independent air treatment system composed of fresh air ventilator and pipeline accessories. The fresh air ventilator filters and purifies outdoor fresh gas and transports it to the indoor through the pipeline. The kitchen fresh air system is to install such a ventilator in the kitchen. The working principle of the kitchen fresh air system is to send fresh air to the room with special equipment on one side of the kitchen, and then discharge it to the outdoor from the special equipment on the other side. A "new air flow field" will be formed in the kitchen to meet the fresh air ventilation of the kitchen. Need, and discharge harmful gases outdoors.
What are the benefits of installing a kitchen fresh air system
1. Help to keep the kitchen tidy
There are many sources of pollution in the kitchen, and many kitchen spaces are small and dense and not ventilated, which causes the kitchen to be unclean and difficult to clean. After using the kitchen fresh air system, the kitchen will form a good ventilation every time the kitchen is cooked, and will not cause the kitchen to be oily.
2. Good ventilation effect
The fresh air system of the kitchen delivers cold air to the sultry kitchen through refrigeration to improve people's comfort in the kitchen environment; and the fresh air system of the kitchen has a simple structure, simple installation, and good cooling effect. Air kitchen air conditioner. It can quickly discharge the odor in the kitchen, let people have a quiet and comfortable environment when cooking in the kitchen, and also discharge the dirty air, and conduct a thorough filtration and purification, and then introduce fresh outdoor air through the air outlet.
3. Conducive to human health
According to a survey by the World Environmental Protection Organization, after five minutes of cooking, the kitchen PM2.5 will soar nearly 20 times. The PM2.5 is generated from fumes and other gases produced in cooking. Not only can PM2.5 "kill" cells, but it may also induce lung cancer. To kill PM2.5, it is necessary to let the kitchen form a good ventilation effect. The kitchen fresh air system can achieve good ventilation. It can discharge harmful gases in the kitchen through fresh air flow, introduce outdoor fresh air, and achieve good ventilation effect, so as to keep the kitchen clean and tidy, and is beneficial to human health. It is an essential choice for a perfect kitchen.
Kitchen fresh air system design
1. Define the trend of fresh air pipeline
Fresh air enters from the cleaner area and is discharged from the dirty area. Generally dirty air is discharged from the bathroom, toilet and kitchen utensils, while fresh air is introduced from the outdoor area. Through the pipeline to each area needed.
2. Determine the amount of exhaust air in the kitchen
In the kitchen, the amount of exhaust air in the kitchen is first accurately calculated, and the total amount of exhaust air is determined. The total amount of fresh air is calculated according to the total amount of exhaust air. Generally speaking, the amount of fresh air in closed rooms is 1/2 of the total amount of exhaust air In order to maintain the balance of indoor wind pressure, the exhaust fumes can be smoothly discharged, and it makes people feel comfortable.
3. The quality of fresh air
Through the front-end filter device, ensure that the introduced air is clean and odorless. Therefore, the effect of the filter device is very important, and it is also important to choose the appropriate air intake point.
4. Partition control
In commercial kitchens, a partition-controlled installation and configuration method is used. That is, the kitchen is divided into several areas, and the total amount of fresh air is allocated to each area according to the amount and area of exhaust air and air quality, and is controlled by a pipe diameter fire valve.
Kitchen fresh air system installation
1. Because the kitchen fresh air system is very simple to install, it can be installed inside the kitchen ceiling, and the operation is convenient and fast, and no wind noise will be emitted during operation.
2. The fresh air system is composed of high-efficiency fans, air inlets, air outlets and various pipes and joints.
The working principle is as follows: exhaust air is implemented in the kitchen with serious pollution (kitchen stove hood area, preliminary processing area, killing area, etc.), the indoor negative pressure formed by the exhaust air allows outdoor fresh air to pass through the window frame or wall The air intakes in the body continuously enter the room, and the paths and air volume of the exhaust and intake air are distributed after strict calculation.
3. In practice, a partition-controlled installation and configuration method is used.
That is, the kitchen is divided into several areas, and the total amount of fresh air is allocated to each area according to the amount and area of exhaust air and air quality, and is controlled by a pipe diameter fire valve.
The commercial kitchen fresh air system is a part of the commercial kitchen project. The commercial kitchen equipment fresh air system is very important. A successful fresh air system must first ensure a balanced air volume and air pressure, and must not have a large impact on the original indoor temperature. Second, the air The flow direction must be smooth, reasonable and comfortable, and there is a time for ventilation. Because kitchen staff are constantly breathing while working, they need fresh air at any time, so the ventilation of commercial kitchens must also ensure that they can work during working hours. Uninterrupted operation. At the same time, we must ensure that the fresh air we enter is clean and healthy.
