Title:
A PROCEDURE FOR CONTROLLING REFRIGERATING MACHINES AND A SYSTEM FOR CARRYING OUT SAID PROCEDURE
Document Type and Number:
WIPO Patent Application WO2002090851
Kind Code:
A3
Abstract:
The invention is directed to a procedure for dynamic coolant control. By using, after mathematical processing, temperatures of incoming and outgoing coolant and pressure and operational data from pumps (2) and pressure sensors arranged within the system as input to the capacity controlling of the refrigerating unit the desired effect can be obtained in a simple way. Apart from the procedure for controlling the regrigerating machine the invention is also directed towards a system that is applied when carrying out said procedure.
