5.1 Operating principle MK compressor automat
The varying pressure levels due to temperature changes in heating or cooling systems are continuously monitored by
the pressure sensor in the compressed air compartment of the vessel. Comparison of these actual pressure levels with a
programmable nominal value leads to the triggering of the valve (release of pressure by means of compressed air discharge)
in the event of the value being exceeded (temperature rise), and triggering of the compressor (increase of pressure by means
of filling the compressed air compartment with compressed air) in the event of the pressure dropping below the nominal
level (temperature drop). The volume of water drained or fed in is made available or taken up by the vessel. Continuous
comparison of the programmable nominal values with the varying volumes registered by the vessel volume sensor prevents
under- or over-filling, whilst allowing volume increase by triggering external top-up devices.
1. Cold
The automat contains
a small amount of
water. The automat is
still at rest.
4. Cooling down
The voume of water
and the system
pressure decreases.
The compressor
increases the
pressure in the air
compartment, water
is transferred back
into the system. This
restores the system
pressure.
3. Full power
By storing an increasing amount of
water in the tank, the automat
keeps the system pressure amost
constant. When the system has
warmed up competey, the vesse
wi be amost fu to capacity.
2. Warming up
The voume of water and the
system pressure increases.
The unit responds to this by
opening the soenoid vave.
Water fows into the vesse.
