Abstract (en)
[origin: EP0412473A2] A method for regulating the internal temperature of a cold load 1 is described, which is connected via two refrigerant pipes, one liquid pipe 2 and a suction pipe 3 to a combination refrigerating system (4, 5, 6). In the method, the internal temperature Ti is measured (11) and the throughput is controlled through both or one of the two refrigerant pipes 2, 3. In this connection, at least one of the two refrigerant pipes 2, 3 is closed when the internal temperature Ti lies below a first limit temperature Tu. If Ti lies above a second limit temperature To, To > Tu, both refrigerant pipes 2, 3 are opened. According to the invention, one of the two refrigerant pipes 2, 3, in particular the suction pipe 3, is opened and closed a number of times, while the internal temperature Ti is situated within the hysteresis interval between Tu and To. <IMAGE>
