<p>The present invention involves a method and a device for regulating the capacity of a vapour-compression-cycle that comprises a compressing device, a condenser, at least one cooler, a variable-flow control means, and an evaporator, connected in series and forming an integral closed circuit with a refrigerant that operates under trans-critical conditions, where in the capacity is regulated by regulating the number of revolutions of the drive shaft of the compressing device as a function of the required capacity; and that the variable flow control means is regulated as a function of the temperature and/or pressure of the refrigerant measured at the high pressure side of the system with respect to optimizing the COP. Hereby it is optained to provide a novel, improved, efficient and simple means for regulating the capacity of a trans-critical vapour-compressing-cycle device avoiding the above shortcomings; and to improve the efficiency of the vapour-compression-cycle process.</p> |
