摘要： A vapour compression system (1) comprising a compressor (2), a condenser (3), an expansion device (4) and an evaporator (5) arranged along a refrigerant path is disclosed. The evaporator (5) comprises at least two evaporator paths (5a, 5b, 5c, 5d) arranged fluidly in parallel between the expansion device (4) and the compressor (2). Each evaporator path (5a, 5b, 5c, 5d) is fluidly connected to the compressor (2) via a separate suction line (7a, 7b, 7c), and the suction pressure in each of the suction lines (7a, 7b, 7c) is distinct from the suction pressure in each of the other suction line(s) (7a, 7b, 7c). The separate suction lines (7a, 7b, 7c) allows the evaporator paths (5a, 5b, 5c, 5d) to be operated at different evaporator temperatures and pressures. Thereby a large temperature change of a secondary flow (6) across the evaporator (5) can be obtained while the suction pressure of a part of the mass flow is kept at a high level. The work required by the compressor (2) is reduced and energy is conserved.

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 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.
摘要翻译：公开了一种用于控制制冷剂流入蒸气压缩系统中的蒸发器的方法。蒸汽压缩系统包括布置在制冷剂流动路径中的蒸发器，压缩机，冷凝器和膨胀装置。蒸发器包括至少两个平行流体排列的蒸发器管，并且流体连接在膨胀装置和蒸发器管之间的集管。该方法包括交替地允许和防止混合相制冷剂流入集管中的步骤。以使得集流管中的压力水平显着和突然增加的方式进行允许混合相制冷剂流入集管的步骤。因此，混合相制冷剂的液体部分和气体部分基本均匀地分布在集管中。因此，制冷剂的液体部分在蒸发器管中以大致均匀的方式分布，并且在管中获得相同的填充度。可以更大程度地利用蒸发器的潜在制冷能力，而不会使液体制冷剂通过蒸发器。

摘要： A method for calibrating a superheat sensor (5) for a refrigeration system is provided. The method comprises the following steps. Increasing an amount of liquid refrigerant in the evaporator (1), e.g. by increasing an opening degree of the expansion valve (3). Monitoring one or more parameters, e.g. the temperature of refrigerant leaving the evaporator (1), said parameters reflecting a superheat value of the refrigerant. Allowing the value of each of the parameter(s) to decrease. When the value(s) of the monitored parameter(s) reaches a substantially constant level, defining the superheat value corresponding to the constant level to be SH=O. The superheat sensor (5) is then calibrated in accordance with the defined SH=O level. When the parameter(s) reaches the substantially constant level it is an indication that liquid refrigerant is allowed to pass through the evaporator (1), and thereby that the superheat of the refrigerant leaving the evaporator (1) is zero. Calibration can be performed on site, and it is therefore not necessary to calibrate the sensor (5) at the manufacturing facility. Thereby it is no longer required to match calibration information with a specific sensor.

The distributor comprises an inlet part (5) fluidly connected to the inlet opening, and is arranged to distribute fluid medium received from the inlet opening to at least two parallel flow paths, preferably of a heat exchanger (3). The valve assembly (1) further comprises a first valve part and a second valve part arranged movable relative to each other in such a manner that the mutual position of the valve parts determines the fluid flow from the inlet opening to each of the outlet openings of the outlet part. Finally, the valve assembly (1) comprises a header (2) forming an integral part of the valve assembly (1). The header (2) is arranged to form an interface towards a heat exchanger (3) comprising at least two flow paths, and it provides fluid connections in such a manner that each of the outlet openings (7, 9) is fluidly connected to a flow path of a heat exchanger (3) connected to the header (2).

摘要： 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.
