서재형,김형진,정광종,김대원,염정국,이무연 대한설비공학회 2013 International Journal Of Air-Conditioning and Refr Vol.21 No.2
In spite of the increase of the concern on electric vehicles (which is called green cars) and electrically driven automotive air conditioning system, the conventional automotive air conditioning system for internal combustion engines has been still investigated widely due to the realistic consideration. This paper is intended to include many automotive air conditioning system articles published in 1997 to 2013. This review, although extensive cannot include every paper; some selection is necessary. Reviewed papers herein are related to the research and development on e®ective design and performance improvement for the automotive air conditioning system and components, including theoretical, numerical, analytical and experimental works. Therefore, a number of published articles about the automotive air conditioning system, which contain the belt-driven compressors, heat exchangers and refrigerants, were considered. Many researches have focused on improving the e±ciency of automotive air conditioning system to decrease the usage rate of the internal combustion engines.

This study analyzed the relationship between the real estate regulatory policy and easing policy, and apartment sales prices in the metropolitan area and Seoul, using apartment price indexes and macroeconomic indicators from January 2004 to December 2021. As a result of the analysis, the real estate regulatory policy had a statistically significant positive effect on the apartment sales price in six metropolitan cities, the Seoul apartment sales price, and the Gangnam apartment sales price. Contrary to the policy goals of the real estate regulation policy, this has the effect of raising the sale price of apartments in six metropolitan cities, Seoul apartments and Gangnam apartments, showing a paradox of regulation. On the other hand, the real estate easing policy was found to have a statistically significant wealth effect on the sale price of apartments in the metropolitan area, apartment sales prices in six metropolitan cities, Seoul apartment sales prices, and Gangnam apartment sales prices, and Gangbuk apartment sales prices.
