Abstract
This article presents a review of potential technologies and strategies to develop an energy-efficient automotive air-conditioner based on the vapor-compression refrigeration cycle system. This paper is broadly divided into two sections. The first is a review of component optimization (primary and secondary components) that enhances the energy efficiency of the automotive air-conditioning (AAC) system. The second presents a review of operational management and control that efficiently consumes energy in operating the AAC system while maintaining vehicular thermal comfort satisfaction. Some of the technologies and strategies described in this article are still conceptual and are the subject of ongoing research. However, the growing demand to reduce energy consumption by developing a new AAC system has led to an increasing number of related studies aimed at generating alternative conventional systems in the near future.
