METHOD AND SYSTEM FOR CONTROLLING A CARNOT-CYCLE PROCESS

摘要

The invention relates to a method and to a system for controlling a carnot-cycle process, said device and system comprising, in a working medium circuit, at least one of the following: a compressor (12), a condenser (18), an expansion valve (20), an evaporator (12) in addition to a multi-phase internal heat exchanger (14). The latter is cross-flown by the condensed working fluid exiting the condenser and by the working fluid exiting the evaporator. The gaseous working means are heated and the condensed working fluid is cooled. The temperature of the hot gas is controlled by means of a computer-controlled control unit (30). In order to maintain a narrow limit for the allowed maximum temperature for the condenser (18), a bypass (52), which surrounds the secondary side (14S) and which comprises a control element (54), is provided.
