Fonctionnement d'un système frigorifique dans des conditions de perturbations externes.

Operation of refrigeration system under conditions of external disturbances.

Auteurs : BOHDAL T., BUTRYMOWICZ D.

Résumé

The investigations of the boiling process in the coil tube under conditions of the unstable operation of the thermostatic expansion valve (the so-called valve hunting) have been presented. The condensation process inside the coil tube condenser under external disturbances produced by the opening and closing of the cut-off valve located at the inlet to the condenser for the refrigerant R-404A has been presented. The wave nature of the boiling and condensation processes in the coil tube have been revealed. The induced disturbances are found to propagate along the coil tube in the form of pressure and temperature wave of propagation velocities which have been determined. The described fluctuations make the refrigeration systems' operation unstable and disturbed.
