Publication number: 20200148026Abstract: The present invention relates generally to an automatic cooling/heating control method of an air conditioner for a vehicle. The present invention is intended to propose the control method, wherein instead of controlling indoor temperature via manual manipulation, operation modes set in figurative languages, not temperature, are used so as to automatically control indoor cooling/heating, whereby an atmosphere more pleasant than an atmosphere provided by a conventional method is efficiently provided and manipulation frequency of a console is reduced. To achieve the above objects, the control method includes: selecting an air operation mode desired by a user; starting an initial operation by the air conditioner after determining whether to cool, heat, or fan; setting the indoor temperature according to the outdoor temperature; resetting the set indoor temperature by using a correction value according to present indoor temperature; and operating by setting a reset indoor temperature to be a final set temperature.Type: ApplicationFiled: November 22, 2018Publication date: May 14, 2020Applicant: CEDIC CO., LTD.Inventors: Jang-Hyung CHO, Wan-Ho JEON, Byeong-Kang Yoo, Joo-Ho SIM

Patent number: 10174801Abstract: A brake disc manufactured by a method of manufacturing a brake disc according to the present invention includes a carbon fiber Cf, silicon Si, silicon carbide Sic, and a silicon-copper alloy SixCuy. The carbon fiber Cf, silicon Si, carbon C, and silicon carbide SiC make a disc light and provide high thermal shock resistance, anti-oxidation, wear resistance, strength, and friction coefficient. The copper Cu and silicon-copper alloy SixCuy increase heat capacity at constant volume of a disc, so a large increase in temperature of the disc is prevented and a changing range of the friction coefficient is reduced in braking. Accordingly, the brake disc according to the present invention has all of the advantage of a brake disc made of a carbon fiber-reinforced ceramic composites without thermal deformation and deterioration of a pad, a hat part, and a caliper.Type: GrantFiled: December 7, 2015Date of Patent: January 8, 2019Assignee: DACC CARBON CO., LTD.Inventors: Dong Won Im, Yeon Ho Choi, Kang Yoo, Nam Cheol Lee
