RECOVERY OF CONDENSATION HEAT
Recovery of heat from de-superheating and condensation of the refrigerant leaving the compressor enables
the production of hot water. Without heat recovery this heat is dissipated in the environment via the finned
condenser coils.
The diagram below shows the partial heat recovery circuit. The cooling and hydraulic circuit diagrams are
included with all ARA units with heat recovery.

In order to ensure the correct functioning of the chillers avoid that the heat recovery plate exchanger D is
powered by water which is too cold. For this reason use of a three way valve VM is strongly advised yet
remains the responsibility of the installer (see diagram).
Heat recovery
uses plate heat exchangers located on the output line before the air-cooled condensers and
supplied with water from the user system. Condensation control, as described above, is included in units with
heat recovery.
INSTALL a metal filter on the piping at the unit intake to stop the heat exchanger getting blocked by flakes of
welding or rust.
