THE SERIES HWMC
1.1
FIELD OF APPLICATION
The DC INVERTER multi-purpose
HWMC
units have been designed to cool
and heat water for air conditioning and heating systems and for the production
of DHW for residential or commercial use. The units are “real” multipurpose
units, with 4 water collections, whose operating modes are described below:
1. Cold water production in summertime mode, for the air conditioning
system (air condensing system on the finned exchanger)
2. Cold water production in the summertime mode, for the air conditioning
system, with TOTAL CONDENSATION HEAT RECOVERY (for the production
of DHW by means of a dedicated plate exchanger)
3. Production of hot water in wintertime mode, for the heating system,
functioning as a traditional heat pump (air evaporation on the heat
exchanger side and water condensation on the dedicated plate heat
exchanger on the system side)
4. Domestic hot water production in wintertime mode, temporarily stopping
hot water production for air heating purpose (DHW priority);
5. DHW production only (in particular in mid seasons and in summertime
and wintertime)
Warning
When reference is made to the production of domestic
hot water, what is meant is the storage of thermal energy in a tank of
“technical” water. Water for domestic use must be heated by means
of a stainless steel coil contained inside the storage tank, in this way
it is possible to avoid storing domestic water and it is not necessary
to provide for an anti-Legionella cycle (see recommended plumbing
layouts for further details).
Warning
HWMC
units are NOT suitable for use as “rapid” heaters."
The HWMC units are designed for outdoor installation (protection rating
IP24), in a position not accessible to the public.
If protection grilles (accessory) are not provided or if the unit can be reached
by unauthorized persons, special protection barriers should be provided in
order to prevent access to the finned coil.
Do not install the unit in places where inflammable gases or powders
are present.
