Benefits of the WY/WR2-Series
What is Water-Cooled?
A unique system from Mitsubishi Electric
It is possible now to combine the features of VRF with a water circuit using CITY MULTI
WR2/WY. In this case, the heat is discharged to a water source rather than to the outside
air.
The advantages of a water cooled system are that the water can be delivered at optimized
temperatures and volumes, which allows even greater flexibility and increased COP.
Water cooled systems are ideal for use in temperate and cooler climates, since it
does not involve heat exchange with the outside air.

Simultaneous heating and cooling operation is possible. (WR2-Series)
Water cooled systems are recommended for use in buildings that have the following heating and cooling needs.
• Buildings that require year-round cooling
For example,
• Tenant buildings in which kitchens and offices exist together
• Buildings in which equipment rooms and offices exist together
• Buildings in which there are large room temperature differences between sunny and unsunny rooms
• Hotels in which there are a lot of individual operation needs
• Installation image

Water cooled systems
can be used even in
buildings that are taller
than 50 m by running a
main water pipe through
each floor.
Any heat source system
that can supply heat
source water between
10°C~45°C can be
used.
