Abstract
A refrigeration apparatus including a compressor (), a condenser (), an expansion device (), and an evaporator (), fluidly connected to form a refrigeration cycle for a refrigerant, wherein the compressor () has a variable working capacity, and wherein the expansion device () has a configurable flow resistance with respect to the refrigerant passing through the expansion device. The apparatus further includes a controller () which is configured to determine a current working capacity of the compressor () and to control the resistance of the expansion device () in dependence on the current working capacity of the compressor (). The controller () is further configured to control the resistance of the expansion device () in order to achieve a mass flow of the refrigerant through the expansion device (), which mass flow corresponds to a mass flow of the refrigerant through the compressor ().
