Abstract: The invention provides a refrigeration system with a compressing unit, and a method of controlling a refrigeration system. To facilitate a better control, the capacity of the compressing unit is controlled based on a predicted future cooling demand rather than an actually determined cooling demand. The invention further provides a system wherein a cost value for changing the cooling capacity of the system is taken into consideration.

Abstract: An expansion valve (4) for a vapour compression system (1), and a vapour compression system comprising such an expansion valve (4) are disclosed. The expansion valve (4) comprises a first valve member (7) and a second valve member (8). The first valve member (7) and the second valve member (8) are arranged movably relative to each other, and the relative position of the first valve member (7) and the second valve member (8) determines an opening degree of the expansion valve (4). The first valve member (7) and/or the second valve member (8) is/are automatically movable in response to changes in a differential pressure across the expansion valve (4), the opening degree of the expansion valve (4) thereby being automatically altered in response to changes in the differential pressure across the expansion valve (4). It is ensured that the opening degree of the expansion valve (4) is automatically adjusted to the actual operating conditions, thereby optimising the efficiency of the vapour compression system (1). Furthermore, this is obtained in a simple manner, without requiring complicated control of the valve (4).

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 heat exchanger, such as an evaporator (1) or a condenser (17), for a vapour compression system (15) and a vapour compression system (15) with such a heat exchanger are disclosed. The heat exchanger comprises at least two flow tubes arranged fluidly in parallel, an inlet manifold (3) and an outlet manifold (7). Each flow tube fluidly connects the inlet manifold (3) and the outlet manifold (7), and fluid medium is distributed among the flow tubes by the inlet manifold (3). The outlet manifold (7) is provided with a suction line heat exchanger, preferably being fluidly connected in a refrigerant path of the vapour compression system (15) between a condenser (17) and an expansion device (18), in the case that the heat exchanger is an evaporator (1). The suction line heat exchanger is arranged in the outlet manifold (7) in such a manner that direct thermal contact is provided between the refrigerant delivered from the flow tubes and the suction line heat exchanger, the refrigerant, e.g., being sprayed directly onto the suction line heat exchanger. Refrigerant leaving the evaporator (1) is heated, thereby causing evaporation of possible liquid refrigerant. Thereby liquid refrigerant can be allowed to pass through some of the evaporator tubes (2) without risking damage to the compressor (16). Utilisation of the potential refrigeration capacity of the evaporator (1) is improved. Arranging the suction line heat exchanger in the outlet manifold (7) provides a compact design and eliminates the requirement for additional components.

Abstract: A method for controlling operation of a vapour compression system (1) is disclosed. The vapour compression system (1) comprises a compressor (2), a condenser (3), an expansion device (4) and an evaporator (5) arranged in a refrigerant path. The method comprises the steps of obtaining values of an entity being indicative of a current distribution of liquid refrigerant of the vapour compression system (1) and comparing the obtained values to a predefined threshold value. In the case that the obtained values are below said threshold value, control parameter values being indicative of the amount of liquid refrigerant present in the condenser (3) are obtained, and operation of the vapour compression system (1) is controlled in accordance with the obtained control parameter values and in such a manner that the amount of liquid refrigerant in the condenser (3) is maintained at a substantially constant level. This prevents flash gas at the inlet of the expansion device of the vapour compression system (1).

Abstract: A method for controlling a refrigerant distribution in a vapour compression system, such as a refrigeration system, e.g. an air condition system, comprising at least two evaporators. The refrigerant distribution determines the distribution of the available amount of refrigerant among the evaporators. While monitoring a superheat, SH, at a common outlet for the evaporators, the distribution of refrigerant is modified in such a manner that a mass flow of refrigerant to a first evaporator is altered in a controlled manner. The impact on the monitored SH is then observed, and this is used for deriving information relating to the behaviour of the first evaporator, in the form of a control parameter. This is repeated for each evaporator, and the refrigerant distribution is adjusted on the basis of the control parameters. The impact may be in the form of a significant change in SH. Alternatively, the control parameter may reflect a change in SH occurring as a result of the modification of the distribution of refrigerant.
