1. Different widths choose different specifications, different heights choose different air supply methods
First calculate the cold wind invasion of the door, and then combine the size and height of the door to select the impeller form and diameter of the impeller.
According to the width and height of the door, the local actual temperature wind is made to make a choice, and the size of the curtain machine is defined by the door width.The 3 -meter uses the flow type. The door width can use two 900 ~ 1000 in 2000mm, or one 1800 ~ 2000.The specific specifications of the screen machines are 900mm, 1000mm, 1200mm, 1500mm, 1800mm, and 2000mm 6 size specifications. According to the method of refrigeration and heat, it is divided into models such as water heating and electricity, heat and cold.
Second, different choices of different choices are different at the same speed
1. Supermarket banks are generally 2.5-3 meters height, and the optional wind speed is 11-13 meters/s;
2. The factory is generally 2.8-5 meters. Food factories cost high air volume and large models. Generally, centrifuge is 20-30 meters/s;
4. The wind wheel 150mm is mainly for industry, because the small amount of noise has been eliminated by the centrifugal curtain machine.
