Abstract
An automotive air conditioning apparatus includes a Stirling refrigerator. In this refrigerator, many fins absorb heat from air in a passenger room, and a water jacket is connected to the cooling circuit of the vehicle engine by way of a pipe. Since an operating gas absorbs heat at the time of isothermal expansion, fins cool the passenger room without using Freon. So, a condenser is not required. Although the operating gas is heated at the time of isothermal compression, the water jacket radiates heat to circulating water of the vehicle engine. So, an individual, i.e., radiator is not required.
