Car air conditioner

Abstract

Abstract PURPOSE:To improve the inhabitability of an assistant seat and effectively perform the air temperature control by making the air flow area of a heating heat exchanger smaller than that of a cooling heat exchanger and interlocking an air mix damper provided on a bypass passage and a hot water valve. CONSTITUTION:The air introduced by an air introducing fan 1 is cooled by a cooling heat exchanger 2 and is divided into a heating heat exchanger 3 and a bypass passage 14 located downstream. The air B warmed by the heating heat exchanger 3 and the cool air C passing the bypass passage 14 via the cooling heat exchanger 2 is mixed in an air mix chamber (a) and it is blown out into a car room through predetermined blowout ports respectively. In this case, the inside/outside air introducing fan and a cooling unit are stored in a composite unit 10, and the inhabitability of an assistant seat is improved. In addition, by interlocking a damper 8b and a hot water valve 15 adjusting the hot water flow to the heating heat exchanger 3, the air mix feature and the temperature control of the introduced air can be made effective.
