-
- Furthermore, this example is useful to understand the different sizing options.
- The selected value of QCoo_flow_nominal
leads to
- conflicting scaling factors for heating and cooling operation. This triggers a warning.
- Using the default QCoo_flow_nominal
, the warning disappears.
- Increasing (or decreasing) it, the number of on-off switches will increase (or decrease)
- in cooling operation due to the low inertia of the system.
- In real air-to-water systems, thermal energy storage would be used to
- decrease cycling if the device is oversized.
