Lower capacity
is required to cool
and heat a building
during mid-season.
A VRV system adapts to
the required changes in
capacity by varying the
refrigerant volume. This results
in an increase in efficiency at
part load operation.
The efficiency of the
VRV IV system is further
increased by adjusting the
refrigerant temperature
depending on space load
and weather conditions.
