PURPOSE:To increase air conditioning function by poproviding in parallel a sub-evaporator in the side-direction of a heater-core and regulating the air quantity rate of the air passing through the heater-core and the air passing through the sub-evaporator. CONSTITUTION:A refrigerating cycle C uses a compressor 1 having one discharge opening 1a and two independent inlet openings 1b, 1c, and connects a sub-evaporator 3 in parallel with a main evaporator 2 through an opening and closing valve 7a. Accordingly, when an air flow passage on the sub- evaporator 3 side is opened by a damper 8 for temperature control at a time of high-level mode, cold air cooled at the main evaporator 2 is again cooled at the sub-evaporator 3. By this, air conditioning capacity can be increased without increasing the capacity of the compressor. |
