Abstract
A heater and/or air conditioner with air-side temperature adjustment includes adjustment with an air-mix flap in front of a mixing chamber, which with a simple and compact construction, guarantees a clear separation between intake-side fresh-air conduction, on the one hand, and warm air conduction, on the other hand, and exhibits only a small air-side contact resistance. A ring-shaped heat exchanger which is closed upon itself, is provided with a ring-shaped surrounding warm-air-duct disk and an axially upstream, ring-shaped surrounding cold-air-duct disk in each case on the outlet side with a crossover branching off into a shared mixing chamber controllable by an air-mix flap with a connected floor air duct or defrost air duct.
