ASSUMPTIONS

Edit the training references and model boundaries below, then apply them to the current simulation. Changes remain in place when you reset a run. RESTORE DEFAULTS returns all assumptions to the agreed baseline without clearing the run.

JT pressure drop always references compressor discharge minus suction pressure. Recycle raises suction and reduces discharge. The phase split uses the existing refrigerant model; fitted flow curves and exchanger topology remain part of the model. Compressor gains and transport delays are illustrative training assumptions.

Temperature comparison by elevation

MODELLED INDICATIONS

Elevation / °C	Shell	Feed circuit	LMR circuit	HMR circuit	Local spread

Spreads compare circuits at one elevation. Non-flowing circuit temperatures are indicative only. HMR is absent from the cold bundle. Trend traces use different line patterns.

Explore the dynamics

TRY · OBSERVE · ADJUST

Choose a starting point, change a control and watch the trend develop. Compare MAN and AUTO, or repeat a change from a different thermal state.

KEEP EXPLORING

Pause to inspect a response, export the trend, then keep adjusting. The process continues until you pause or reset it. Temperature references and process alerts help explain what is happening.
