摘要

A case for an air conditioning system of a vehicle is provided to prevent air resistance from being unnecessarily increased by allowing air to pass through a heater core and an auxiliary indoor heat exchanger. A case(20) for an air conditioning system of a vehicle comprises a warm air passage(24). An auxiliary indoor heat exchanger(18) and a heater core(30) are provided to heat air introduced into the warm air passage. The warm air passage is divided into a first branch passage(26) and a second branch passage(28). The auxiliary indoor heat exchanger is installed in the first branch passage and the heater core is installed in the second branch passage. Air is selectively introduced into the first branch passage or the second branch passage through a passage switching door(40).
