Publication number: 20230415538Abstract: Proposed are an air conditioner having an integrated heat exchanger and an air conditioning system using the integrated heat exchanger. The integrated heat exchanger enables heat exchange between cooling water and conditioning-air, and generates heating air or cooling air such that cooling/heating efficiency is improved. Further, since the temperature of the cooling water circulating in the integrated heat exchanger is adjusted, there is no temperature adjustment door for adjusting the temperature of conditioning-air, so the number of parts is reduced. Further, since the integrated heat exchanger is applied, components are optimally arranged and the entire package is reduced in size.Type: ApplicationFiled: June 28, 2023Publication date: December 28, 2023Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATION, Hanon SystemsInventors: Kwang Ok Han, Gee Young Shin, Su Yeon Kang, Dong Ho Kwon, Myung Hoe Kim, Dae Hee Lee, In Jae Kang, Tae Young Park, Jae Chun Ryu
