In shopping malls, supermarkets, shops, restaurants, subway high -speed rail stations and other places, due to the large number of people, it is necessary to keep opening and closing to make people enter and exit. In summer, it is easyWhen you need heating, it is easy to make the heating outflow, causing great waste of energy.To cope with this situation, the air curtain products came into being.The air curtain drives a strong airflow through high -speed motors to drive the flow or centrifugal wheel, forming an invisible air curtain, which is convenient for people to enter and exit freely, but also effectively block the cold/heating outflow.The shopping mall can fully open the door during business hours to welcome the guests.
The wind curtain machine can be divided into natural wind curtain machines, hot screen machines and warm and warm air curtains according to different winds.The natural wind curtain machine, as the name implies, is the wind curtain machine that blows the natural wind. In the summer, it gives people a fresh and natural cool atmosphere; the hot -screen machine has an electric heat curtain machine and a water heating off the curtain machine, which generates heat to blow the hot air.The chills on the body; the warm and warm wind curtain machine can blow the natural wind or blow the hot wind. It can switch the wind according to the different seasonal needs, simple and practical.
The principle and scope of the hot wind curtain machine
Common hot -screen machines are mainly electrical heat curtains. Installed without charging PTC heater, heating the airflow of high -speed flowing downward at high speeds under fans, which makes the air curtain blowing the hot air.In addition, there is a water -warming wind curtain machine that needs to be connected by the air -conditioning machine to condense the water pipe; the hot -screen machine is mainly used in northern regions such as North China, Northwest, and Northeast China. In winter, it is necessary to prevent indoor heating outflow and cause energy waste.
The advantages and disadvantages of hot wind curtain machine
1. Effectively block the outflow of indoor hot air in winter, and avoid cold air outdoors into the room.Ensure indoor temperature and reduce energy loss.
2. It plays a role in preventing insects and dust prevention, and keeps indoor air cleaning.
3. Dording indoor and outdoor air can prevent outdoor dirty air from carrying harmful substances into the room to ensure the quality of indoor air.
4. Cold and warm curtain machine can turn off the heater in summer and use it for natural wind curtain machine.
1. The non -charged PTC heater of the hot -fired curtain machine increases the resistance in the air flow, reduce the wind speed of the air outlet, and affect the resistance effect;
2. Most of the hot -windows are mainly electric heating. The power of the heat thermal device is high.
3. The power consumption of the hot screen machine is relatively powerful, and the life span is relatively short;
The above is about the working principle and advantages and disadvantages of the hot -winded curtain machine
