Pilot Test was carried out in 2019, at Châteauneuf-le-Rouge, France. A temporary testing facility has been mounted for this purpose in order to replicate a commonly used heat transfer system. Tap water was utilized as the hot stream to be cooled down. A chiller was installed as source of cooling with the aim of cooling down the tap water stream Aim of the pilot test was to verify enhanced heat transfer created by the introduction of HTF Compact into a base coolant solution composed of 30% ethylene glycol (remaining water) in a process application for cooling. The main assessment to be performed is around the chiller performance.
Energy efficiency by the introduction of HTF Compact (5% v/v) is demonstrated as minimum 15% (±3%) vs baseline conditions (glycol + water).
Performance is measured in relation to the chiller operations time assuming a similar operation throughout the various cases. That means % of time during chiller operating cycle in order to achieve the same cooling setpoint of 5°C.
When HTF Compact is introduced and circulating, setpoint can be reached with chiller operating at 86% of the time.
