Air curtains are divided into non-heated air curtains and hot air curtains according to the processing state of the outgoing air flow. The air curtain is divided into horizontal and vertical installation types, and the heat source types include hot water, steam and electricity.
What are the classifications of air curtains according to the types of fans used?
What is the function of the air curtain?
Can air curtains replace air conditioners?
(1) The cross-flow air curtain, also known as the cross-flow air curtain, has a cylindrical shape. The airflow enters perpendicular to the axis and passes through and discharges in the opposite direction. The airflow at the inlet and outlet of the cross-flow air curtain is in a larger return plane. Very uniform, suitable for occasions with small isolation space.
(2) Centrifugal air curtain, the airflow enters from one end (or both ends) of the wind wheel along the axis, and is discharged from the direction perpendicular to the axis. occasion.
(3) Axial air curtain, the airflow mainly moves along the axis direction, that is, it is close to the axis direction, and also flows out along the axis direction. The axial flow air curtain machine has concentrated air and large air volume. larger occasions.
Insulation function
air curtains are mainly used in places such as restaurants, shops and entertainment venues where customers often come and go and need to keep opening and closing the door. This can maintain the indoor cold and warm air temperature with 60-80% efficiency. Instead, only minor temperature changes are allowed.
Anti-insect function
It can be found that most of the annoying and harmful insects cannot pass through the wind curtain wall. In this way, it is better and easier to maintain the hygiene of fruit counters, fast food restaurants and other places.
Heating function
The air curtain machine also has electric heating air curtain machine, which is generally heated by PTC. There are also water heaters. These two types of air curtains can increase the temperature of the entrance and exit, and are generally used in the north. The elevated temperature varies from 30 degrees to 60 degrees.
The air curtain mainly uses high-speed airflow to block the outdoor odor, oil fume, dust, etc., and plays the role of purifying the air, but the air curtain itself does not have the function of cooling and heating, so the air curtain cannot be used as an air conditioner.
In addition, the main purpose of the air curtain machine is to prevent the cold air generated by the air conditioner from overflowing from the entrance and exit too much, thereby causing waste of resources. Therefore, it is meaningless to install the air curtain machine in a room without air conditioning.
