Abstract: A power module is described. The power module has a first conducting layer, a second conducting layer (on which an electrical circuit is provided), an insulating layer (such as a ceramic) between the conducting layers and a liquid cooling mechanism. The first conducting layer is exposed to the liquid cooling mechanism and is etched (or modified in some other way) in order to increase surface area (thereby increasing the effectiveness of heat removal by the liquid cooling mechanism). The power module is encapsulated to improve mechanical stability.

Abstract: A method for coordinating operation between at least two groups of compressors in a cooling circuit is disclosed. A first group of compressors forms part of a low temperature (LT) part of the cooling circuit and a second group of compressors forms part of a high temperature (MT) part of the cooling circuit. Each of the compressor groups comprises one or more compressors, and each of the compressor groups comprises a controller, the controllers being capable of exchanging signals. In the case that the LT compressor group needs one or more of the LT compressors to start operation, it is investigated whether or not one or more of the MT compressors is/are operating. If this is the case, one or more of the LT compressors is/are allowed to start operation. If it is not the case, the suction pressure in the MT part of the cooling circuit is established, e.g. measured, and compared to a lower and an upper limit of a neutral pressure zone, said neutral pressure zone lying within an operating pressure zone of the MT part of the cooling circuit. Finally, the MT compressors and the LT compressors are operated based on the comparing step. The cooling system may be a cascade system or a booster system.

Abstract: A method for operating a vapour compression system (1) is disclosed. The vapour compression system (1) comprises a compressor (2), a condenser (3), at least one expansion device (4), an evaporator (5), said evaporator (5) comprising at least two evaporator paths (5a, 5b) arranged fluidly in parallel, and a distribution device arranged to distribute refrigerant among the evaporator paths (5a, 5b). The method comprises the steps of obtaining at least two predefined distribution keys, each distribution key defining a distribution of available refrigerant among the evaporator paths (5a, 5b), detecting one or more operational settings of the vapour compression system (1), selecting one of the at least two predefined distribution keys, based on said detected operational setting(s), and distributing refrigerant among the evaporator paths (5a, 5b) in accordance with the selected predefined distribution key. The predefined distribution keys constitute pre-settings which can be selected on the basis of operational settings, such as compressor capacity, fan speed, refrigeration load or mode of operation. The vapour compression system (1) may be operated in accordance with the selected predefined distribution key, or the selected predefined distribution key may be used as a suitable starting point for an adaptive adjustment of the distribution key. An optimal distribution of the available refrigerant among the evaporator paths (5a, 5b) is quickly reached due to the pre-settings. Thereby the vapour compression system (1) can be operated in an optimal manner for most of the operating time.

Abstract: An expansion valve (1) comprising an inlet opening and at least two outlet openings (5) is disclosed. The inlet opening is adapted to receive fluid medium in a liquid state, and the outlet openings (5) are adapted to deliver fluid medium in an at least partly gaseous state. The expansion valve (1) further comprises a diaphragm (6), and at least two valve seats (4), each valve seat (4) being fluidly connected to one of the outlet openings (5). Each of the valve seats (4) forms a valve in combination with the diaphragm (6), the position of the diaphragm (6) thereby simultaneously defining an opening degree of each of the valves. A well defined distribution of fluid flow towards each of the outlet openings (5) is easily defined by movements of the diaphragm (6). The distribution takes place before or during expansion of the fluid medium. The expansion valve (1) may be arranged in an refrigerant path of a refrigeration system.

Abstract: This invention relates to a method of performing control of a closed loop control system controlled by a controller, wherein said controller delivers the control input to at least one control unit in said system e.g. a valve, said method comprises the steps of: - detecting the oscillation level in said control input to said control unit, - amplifying said control input by a multiplication factor based on said detected oscillation level. Thereby characteristics of the control unit are changed as oscillations are detected. Thereby oscillations are minimized, and e.g. the wear of the control units is reduced and an improved control is obtained.

Abstract: 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.
