11. Disassembly of heater
Air-conditioning
Heat is removed from evaporator (5) inside the cabin (low-pres-
sure loop) and delivered on the condenser (2), located in front of
the engine radiator (high-pressure loop). Compressor (1) sucks
cooling vapors from the evaporator and presses them to con-
denser (2). There the cooling vapors are condensed and ow
over dehydrating lter (3) to heat expanding valve (4). Valve 4
sprays liquid coolant to evaporator (5), where heat is absorbed
from the cabin, the liquid evaporates, and the vapors are sucked
in to the compressor.
