2.7 Energy Saving and Optimum Operation
This
VRV
system is equipped with advanced energy saving functionality. Depending on the priority,
emphasizes can be put on energy saving or comfort level. Several parameters can be selected,
resulting in the optimal balance between energy consumption and comfort for the particular
application.
Several patterns are available and explained below. Modify the parameters to the needs of your
building and to realize the best balance between energy consumption and comfort.
2.7.1 Target Temperature Settings
• Basic
The refrigerant temperature is fixed independent from the situation.
It corresponds to the standard operation which is known and can be expected from/under previous
VRV
systems:
To activate this operation method under cooling operation, change field settings [2-8] to 2 and
[2-81] to 0.
To activate this operation method under heating operation, change field setting [2-9] to 6 and
[2-82] to 0.
• Automatic
The refrigerant temperature is set depending on the outdoor air conditions. As such adjusting the
refrigerant temperature to match the required load (which is also related to the outdoor air
conditions).
E.g., when your system is operating in cooling, you do not need as much cooling under low outdoor
air temperatures (e.g., 77°F (25°C)) as under high outdoor air temperatures (e.g., 95°F (35°C)).
Using this idea, the system automatically starts increasing its refrigerant temperature, automatically
reducing the delivered capacity and increasing the system’s efficiency.
To activate this operation method under cooling operation, change field settings [2-8] to 0
(default).
E.g., when your system is operating in heating, you do not need as much heating under high
outdoor air temperatures (e.g., 59°F (15°C)) as under low outdoor air temperatures (e.g., 23°F
(–5°C)).
Using this idea, the system automatically starts decreasing its refrigerant temperature,
automatically reducing the delivered capacity and increasing the system’s efficiency.
