As a result of this study, the performance evaluation of the development of laminated paper automatic adhesive processing machine is considered and concluded as follows. The cardboard processing unit for automatic folding and gluing designed a feeder for supplying cardboard, and the prototype production was compared with the existing production and the developed product, and the production rate was improved from 31,100 to 46,500 pieces per day, and the production speed was increased from 68 to 98. The defect rate was solved by solving the folding problem by comparing the existing production and the developed product, and the standard of the defect rate of the product was based on the folding, and the X1-X4 average defect rate was confirmed to be 0,000607%.

The change in the performance of the range hood according to the pressure change was investigated through a comparative experiment, and the conclusion is as follows. KS C 9304: In 2020, static pressure was applied at 100 Pa according to the fan standard, and the test was conducted by varying the outlet diameter and power consumption. In the case of Motor power 55W, the air volume value was 184.6 when the outlet diameter was 125mm. As a result of the test, if the power consumption is 52.0W, the diameter of the outlet is 125mm, and the power consumption is 60.8W, and the diameter of the outlet is 100mm, it meets 160 or more and less than 200 (constant pressure 100Pa).

Recently, as interest in external environments such as fine dust has increased, the interior environment is also becoming important. The specifications for range hoods in the kitchen have been changed to improve ventilation of indoor air. Accordingly, the performance improvement through the structural design of the range hood was studied. Experiments were conducted on flow rates, pressure, temperature, and noise by A, B, and C-Type for performance analysis according to internal structure. For C-Type, the wind volume () was 223.69, 2nd stage 257.46, showing results of not less than 240 and not more than 280 within the ±1 m/s flow rate error range. Noise (dB) was an average value of 54.83 in the first stage and 60.65 in the second stage, showing results not more than 60 dB within the ±1 dB margin of error. This is the result of meeting KS C 9304:2020 Ventilation System Specification.
