Abstract: An expansion device unit (4) for a vapour compression system (1), and a vapour compression system (1) are disclosed. The expansion device unit (4) comprises an inlet opening (17) arranged to receive fluid medium, at least two outlet openings (18) arranged to deliver fluid medium, a main expanding section (6) adapted to expand fluid medium received via the inlet opening (17) before delivering the fluid medium to the outlet openings (18), and a distribution section (7) arranged to split the fluid flow received via the inlet opening (17) into at least two fluid flows to be delivered via the outlet openings (18). The main expanding section (6) and/or the distribution section (7) is/are arranged to cause pressures in fluid delivered via at least two of the outlet openings (18) to be distinct. The main expanding section (6) is operated on the basis of one or more parameters measured in the fluid flow delivered by one of the outlet openings (18). The distinct pressure levels allow distinct evaporating temperature in evaporator paths (5a, 5b, 5c) connected to the outlet openings (18). Thereby a large temperature difference between inlet temperature and outlet temperature of a secondary fluid flow across the evaporator (5) can be obtained, without requiring that the entire mass flow must be compressed from a low pressure level by the compressor (2). Thereby energy is conserved.

Abstract: A vapour compression system comprises a compressor, a condenser, an expansion device, e.g. in the form of an expansions valve, and an evaporator arranged along a refrigerant path. A method for operating the vapour compression system comprises the steps of: obtaining a superheat value being representative for the superheat of refrigerant entering the compressor; obtaining a subcooling value being representative for the subcooling of refrigerant entering the expansion device; and operating the expansion device on the basis of the obtained superheat value and on the basis of the obtained subcooling value. The subcooling value is taken into account when operating the expansion device, because variations in the subcooling value have significant influence on the refrigerating capacity of the evaporator at a given opening degree of the expansion device, thereby resulting in a more stable operation of the system. The system may further comprise an internal heat exchanger.

Abstract: A method for controlling a refrigeration system with a variable compressor capacity, and at least two refrigeration entities, e.g. display cases, includes controlling suction pressure by either permitting or preventing the flow of refrigerant into the evaporators of one or more refrigeration entities. The method also includes controlling compressor capacity based on a signal derived from one or more properties of the one or more refrigeration entities, said signal reflecting a possible difference between the current compressor capacity and a current refrigeration demand of the refrigeration system. The method reduces wear on compressors by avoiding switching them ON or OFF to the largest extent possible, and also prevents problems relating to conflicting control strategies due to control parameters, e.g. suction pressure, being determined based on two or more controllable parts, e.g. compressors and flow of refrigerant into refrigeration entities.
