French term or phrase: machine de type BUA (Boucle Unitaire Ambiante)
It is the first time I cannot figure out a term.

Faisant suite à la demande de ... portant sur des essais de performances d’une de leur machine de type BUA (Boucle Unitaire Ambiante), ... a réalisé une prestation in situ qui se découpe en 3 parties distinctes.

The "3 parties distinctes":
proceeded to calibration of the sensors of acquisition system with which the machine is equipped,
assisted to the performance of the tests and archived the raw data recorded by the acquisition system.
studied the tests by applying the necessary corrections to the recordings and calculated the refrigerating capacities (Q0), mechanical power (Pmec.) and hydraulic power (Phyd.) over 3 different periods.

This "BUA" type machine uses "active magnetic regenerator (AMR) cooling cycle", which is something new. It implies a heat transfer fluid acts as the vehicle for heat transfer and is arranged to flow back and forth between the cold-side heat exchanger to the hot-side heat exchanger through the active magnetic regenerator in a cycle. A magnetic field is repeatedly applied to and removed from the active magnetic regenerator, thereby causing it to heat up and cool down" using a unitary loop.

I tried to google the French term and it does not return any exact French term.
From piecing together the fragment of information in French and English, I think it might be translated as Ambient Unitary Loop.

at http://www.iftomm-terminology.antonkb.nl/2057_1036/04.html I found

RETROACTION PRIMAIRE [SIGNAL DE RETOUR UNITAIRE] PRIMARY FEEDBACK
Signal that is a direct measure of the output of a system and is compared directly with its input signal de retour unitaire/ primary feedback signal.

GAIN CROSSOVER
Point in the plot of loop gain at which the magnitude of loop gain is unity.
POINT DE COUPURE DE GAIN
Point de la courbe de gain en boucle ouverte pour lequel le gain est unitaire.

4.1.15 LOOP GAIN
Magnitude of the open-loop harmonic response.

4.1.15 GAIN EN BOUCLE OUVERTE
Amplitude de la réponse en fréquence en boucle ouverte.
