摘要

The system has a mixing volume (35) including an air flow control unit (32) to regulate amount of air guided from a hot air volume (45) and a cold air volume (25) into the volume (35). Another mixing volume (65) has an air flow control unit (62) i.e. drum flap, and is loaded with air from the volume (35), another cold air volume (75) and the volume (45). The volume (65) and the control unit (62) are attached to the volume (35) and the volume (45).
