摘要： 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.

摘要： A method for controlling a flow of refrigerant to an evaporator arranged in a vapour compression system is disclosed. The vapour compression system comprises the evaporator, a compressor, a condenser, and an expansion device arranged in a refrigerant flow path. The evaporator comprises at least two evaporator tubes arranged fluidly in parallel, and a header being fluidIy connected between the expansion device and the evaporator tubes. The method comprises the steps of alternatingly allowing and preventing a flow of mixed phase refrigerant into the header. The step of allowing a flow of mixed phase refrigerant into the header is performed in such a manner that a pressure level in the header is increased significantly and abruptly. Thereby the liquid part and the gaseous part of the mixed phase refrigerant are distributed substantially homogeneously in the header. Thereby the liquid part of the refrigerant is distributed in a substantially uniform manner among the evaporator tubes, and the same filling degree is obtained in the tubes. The potential refrigeration capacity of the evaporator can be utilised to a greater extent without risking that liquid refrigerant passes the evaporator.

摘要： 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).

摘要： The invention provides a method and a system for controlling floor heating or climate regulating systems with long time constants. According to the invention, a flow of a fluid is provided through the floor or through a similar medium with large thermal inertia. An induced heat is determined by adding up a plurality of differences between an inlet temperature of the fluid when it enters the medium and an outlet temperature of the fluid when it leaves the medium. The temperatures are sampled with a fixed sampling time and within a fixed period of time, and a corresponding change in temperature of the medium over the fixed period of time is determined. In the future, the temperature of that medium is controlled by use of a ratio between the induced heat and the change in temperature.

摘要： A method for controlling a temperature in a refrigeration system using a quality decay value expressing an expected decay rate in quality of the products being refrigerated, and which depends on the temperature of air present in the refrigeration system. The quality decay value is obtained using a mathematical model reflecting one or more physical and/or biological processes in the products. Prevents or reduces the quality degradation of the products in terms of shelf life, appearance or tastiness. Furthermore, a method for controlling the temperature in such a way that effects of scheduled events, such as temperature increase during defrosts, can be compensated prior to the event.

摘要： 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).

摘要： An expansion valve comprising an inlet opening and a distributor being arranged to distribute fluid medium received from the inlet opening to at least two parallel flow paths. At least two outlet openings are adapted to deliver fluid in an at least partially gaseous state, and each outlet opening is fluidly connected to one of the parallel flow paths. A first valve part and a second valve part are arranged movably relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines the opening degree of the expansion valve. Since the distributor forms part of the expansion valve, it distributes the fluid medium to the parallel flow paths prior to or during expansion of the fluid medium, i.e. while the fluid medium is in a substantially liquid state. This makes it easier to control the distribution of fluid medium to the parallel flow paths in a uniform manner.
摘要翻译：膨胀阀包括入口开口和分配器，其布置成将从入口开口接收的流体介质分配到至少两个平行的流动路径。至少两个出口开口适于以至少部分气态的状态输送流体，并且每个出口开口流体地连接到平行流路之一。第一阀部分和第二阀部分以这样的方式相对于彼此可移动地布置，使得第一阀部分和第二阀部分的相互位置确定膨胀阀的开度。由于分配器形成膨胀阀的一部分，所以在流体介质膨胀之前或期间，即当流体介质处于基本液态时，其将流体介质分配到平行流动路径。这使得更容易以均匀的方式控制流体介质到平行流动路径的分布。
