1.Microsoft Edge, Google Chrome, or 360 (compatible mode) are recommended;
2.Please fill in the correct phone number, project information and address;
3.The climate parameters of each city are different, which will affect the calculation results. Please be sure to choose the correct city for calculation;
4.Fill in the information of the air pipe, elbow and nozzle connected to each model. When the "wind resistance is too low" or "wind resistance is too high" is displayed, adjust the length of the air pipe, elbow or nozzle until the "wind resistance is too low" or "wind resistance is too high" is not displayed;
5.Fill in the building length, width, height data, city, industry information, air duct information (direct air duct length, number of elbows, number of tuyere, etc.) information, can be calculated according to the following two methods; A.Design temperature according to the hottest day Number of computer units: Enter the design temperature of the hottest day, when the "design temperature is too low" or "design temperature is too high" prompt, the design temperature of the hottest day must be adjusted until the "design temperature is too low" or "design temperature is too high" prompt does not appear, enter the number of machines, click the "Calculate" button, when the "select too few machines" or "select too many machines" prompt appears, The number of machines must be further adjusted repeatedly until "the number of machines selected is appropriate" appears; B.Check the design temperature of the hottest day according to the number of machines: After entering the number of machines, enter the design temperature, when the "design temperature is too low" or "design temperature is too high" prompt, the design temperature on the hottest day must be adjusted, until there is no "design temperature is too low" or "design temperature is too high" prompt, click the "calculation" button, when there is "select too few machines" or "select too many machines" prompt, The design temperature must be further adjusted repeatedly until "appropriate number of selected machines" appears;
6.When multiple units are installed together, the air duct design parameters of each type need to be input, and the air duct parameters are selected according to the longest pipe of the air duct.
