REFRIGERATION SYSTEM

摘要

A refrigeration system (1) is disclosed having a plurality of cooling surfaces (11), each of which is connected by way of a series-connected controlled valve (12) to a common refrigerant supply device (3), and having a control arrangement (13, 18) connected to the valves. It is desirable in such a refrigeration system to render the loading of the refrigerant supply device more uniform. For that purpose the control arrangement (13, 18) generates for each valve (12) a pulse-width modulated signal (25) for operation of the valve (12), all signals having the same period (Tper). The valves (12) of the individual cooling surfaces (11) open at staggered intervals with respect to one another.
