Classification
The air curtain machine can be divided into two categories: hot -screen machine and natural wind curtain machine. From the form of a fan, it can be divided into a flow -type air curtain machine and a centrifugal curtain machine. From the installation form, it can be divided into side hair dryers.Wind curtain machine and top wind curtain machine.Although the air curtain machine can have a variety of different classification methods, and they all have their own characteristics, the application function of the air curtain machine still maintains consistency: energy saving, cleaning, and creating comfortable space.
Energy -saving function
The air curtain machine is a kind of energy -saving equipment, which is mainly reflected in the combination of air -conditioning heating, and it is targeted at the cold and warm in winter for various buildings in summer.For an ordinary door with frequent opening and closing, the cold and calorie loss per square meter per square meter is equivalent to 300m2 cold and calories.The cold and calorie loss of rice are also equivalent to 70m2 cold and calories.In the large -scale building places that have not been installed, the indoor air -conditioning can still feel obvious at 20 meters outside the door. The continuously lost air conditioning makes the inside and outside heat exchanges frequently, causing the air -conditioning equipment to waste air -conditioning.How to effectively avoid the loss of this kind of air -conditioning without affecting normal entry and exit?The application of the air curtain machine is formed.
When the curtain machine achieves this ideal energy -saving effect, it needs to achieve certain conditions.When installing the top hair dryer, the wind speed of 1 meter from the ground is greater than 3m/s; when the side blowing type is installed, the measuring wind speed in the middle position of the single -desk operating door should be greater than 3m/s.When reaching the other side, it should be greater than 3m/s; the open door is effective at the full process of the air width greater than 90%, and the invalid air width should be less than 100mm.For example, when the door is 2 meters wide, when the air curtain machine is out of the air, you can choose two 0.9 -meter -long air curtain or a 1.8 -meter -long flame machine.The wind curtain machine is not when the air outlet (such as the flow -type air curtain machine), and two 1 meter -long air curtain machines or 1.2 meters+0.9 meters should be used (generally for aesthetic suggestion for the same length)EssenceTo meet the two conditions above, installing the screen machine can effectively prevent this cold and frequent exchange, thereby indirectly reduced the cooling burden of air -conditioning equipment and achieve the effectiveness of energy saving.
Cleaning function
For food factories, cafeterias and other clean places, it is extremely important to effectively block mosquito, flies, and insects. The use of windows is the most effective means to block insects and flies.The air curtain machine formed a high air flow velocity at the open door. The local high -wind speed and high air pressure made mosquito flies unable to enter.To achieve this effect, under the same installation and working methods, the wind speed of the wind curtain machine needs to reach 4M/s, and the effective wind width is greater than the range.
When the top is installed, the wind speed of 4m/s at 1m from the ground can effectively block the entry of mosquito flies.When the bilateral blowing is installed, when the single platform is running, the wind speed in the middle of the door is greater than 4m/s. When the unilateral blowing is installed, the wind speed is greater than 4m/s when it reaches the other side.EssenceFor example, the width of the door hole is 2m. When the model is selected: When the windows are the model that is out of the way, you can choose a 0.9m and a 1.2m long wind curtain.Do not choose when the air curtain machine is out of the air.At the same time, it should be able to meet the requirements of the upper speed delivery speed.
Comfortable function
All workplaces will have personnel at work, and the comfort requirements of personnel must be considered.In summer, the air curtain blows the natural wind, which can meet the comfort of the human body. As long as the place where the person is staying, the wind speed is too large.In winter, the personnel part of the personnel will have a cold feeling. Although it can also block the entry of cold winds, when the air curtain machine increases the heating section, it will improve the comfort of the personnel when passing.The temperature of the air should be appropriate. The head and hands of the personnel are the main part of the feeling of comfort. When the air supply temperature reaches the temperature of this area is 40 ~ 50 ° C, it is the most suitable temperature.It is most suitable for others to meet the requirements of the door closure.
