Overview
Set Heating and Chilled Ratings for Emitters to ensure accurate flow rate calculations and optimal thermal performance in each Room. These ratings represent the emitter's heating and cooling output.
How it works:
Heating Rating: Represents the
Emitter’sHeat Output.Chilled Rating: Represents the
Emitter’sCooling Output.These
Ratingsare used to calculate the requiredFlow Ratesand overall system performance, in conjunction with thedelta Tspecified in the equipment supplying theseEmitters.Values are completed in the
Technicaltab of theEmitter’sproperties.
Please Note: For some Emitters (e.g., radiators), these may be informed by the emitter's dimensions and type (e.g., a Type 11 Radiator).
Setting Emitter Ratings
Automatic Calculation
Ratings can be automatically calculated based on the Room’s Heat or Cooling load, assuming heat load calculations are performed in h2x, and the room is associated with that Emitter i.e. its placed in that Room and/or you have specifically ‘Associated’ it in the Technical tab (for AHU, FCU, and Manifolds only):
If the
Room’s load changes, the associated heat load calculations will update too.These
Ratingscan be overridden to account for unique system or room conditions.
Manual Entry
You can manually enter ratings in the Technical tab for precise control or to use specific manufacturer data. Manual entry overrides automated calculations.
Verification and Adjustment
Reviewing and editing Heating/Chilled ratings:
Navigate to the
Technicaltab in theEmitter’sProperties.Check if the value aligns with the
Room’s calculated load or specific requirements.For automated values, verify they match the
Room’s conditions and heat load calculations.Ensure the
Emitter’s type and dimensions (e.g., radiator type) are correct, as these directly impact theRating.
