1.4.3 Consequence of inadequa e energy dissipa ion
Room air/cooling water
Consequences of, for ins ance, con amina ion of he condenser fins, inadequa e clearance be ween
empera ure con rol uni o wall/ba h wall, room air/cooling wa er oo warm, cooling wa er differ-
en ial pressure oo low, suc ion s rainer con amina ion: The refrigeran in he refrigeran circui can
no longer fully discharge he admi ed energy o he room air/cooling wa er. Thus here is no suffi-
cien liquefied refrigeran available, he condensa ion empera ure and he energy consump ion o
rise.
Refrigerant circuit
Consequences of inadequa e refrigeran quan i y/rising condensa ion empera ure: No all he cool-
ing capaci y from he refrigeran circui is available a he evapora or. This means reduced energy
ransmission from he hermal fluid circui .
Thermal fluid circuit
Consequence of inadequa e energy dissipa ion from he hermal fluid: The hermal fluid can only
dissipa e he energy from your applica ion o a limi ed ex en .
Application
Consequences of inadequa e energy dissipa ion from he applica ion: The energy crea ed (exo her-
mic) in he applica ion can no longer be fully dissipa ed.
Temperature control unit
For op imal empera ure con rol performance and maximum cooling power he uni should be used
wi hin he specified ambien empera ure range. The empera ure con rol uni swi ches off when
he upper range is reached (maximum permissible ambien empera ure).
