Chery A series. Manual - part 130
The coolant vapor will be compressed by the compressor as the high-temperature,
high-pressure gas which enters into the condenser. In the condenser, the coolant is cooled by
the ambient air, and condensed into the fluid after emitting its heat outwards, then the
moisture content is filtered and removed from the fluid via the fluid reservoir. The
high-temperature, high-pressure coolant fluid is throttled down through the expansion valve
(installed in the inlet pipe of evaporator) to reduce its pressure and temperature, and then the
fluid enters into the evaporator. The low-temperature and low-pressure coolant fluid also
absorb the heat from the inside of vehicle, and gasifies again to the low-temperature and
low-pressure coolant vapor, and then is inhaled into the compressor. In such a manner, the
coolant cycles recurrently to make the indoor temperature of vehicle reduce. The pipelines
for coolant are shown in the figure below:
2. Heating system It adopts the engine coolant as the heat source and introduces the
coolant into the radiator located at the compartment to heat the indoor air via the blower, and,
at the same time, it is also used to defrost and defog the front windscreen.Chery A15LHD’s
air conditioning unit adopts the reheating mixed type unit, the heating system of which is
used not only to individually heat the circulating air from the inside of vehicle or the fresh air
from the outside, but also to firstly cool these two kinds of airs and then heat the whole or
part to obtain the air temperature required. It is available to dehumidify the air, and also to
filter the air so as to get the clean air with desired humidity.
