strictly observed material damage may be caused.
1.2 Air conditioner description
EIA series of air conditioner is a refrigeration
product designed for the application environment
such as industrial control cabinet. It is suitable for
the application scenario with a larger calorific value
inside the cabinet device, where the internal device
is sensitive to the ambient temperature, to be
completely isolated both internally and externally.
This product has complete function, integrated with
upper computer communications, entrance guard,
external fan control function, condensate water
processing system. It has high reliability, with
simple and convenient installation, which can be
put into operation after electrified, without complex
debugging.
1.2.1 Principles of function
The refrigerant is compressed by compressor (1)
into high temperature and high pressure gas; To
the condenser (3), and suctioned by the cooling
fan (2) from the lower part into outdoor air, where
the heat is forced through the condenser (3) to
spread to the surrounding environment in the air,
and the refrigerant becomes into a liquid through
the throttling element (4), the refrigerant pressure
drops, and in the evaporator (6), the refrigerant
absorbs the heat inside the control cabinet and
evaporates; The hot air is suctioned by the
evaporation fan (5) from inside the control cabinet,
and through the evaporator, the air is cool and
forced to discharge into the inside of the control
cabinet. At the same time, the air inside the control
cabinet is dehumidified.This series can be used a
variety of installations.This is shown in the pictures
below:
