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: The present invention relates to a method and a system to reduce losses of energy due to ripples, especially at the power grid, the ripples being short term power shortages or excess power. The method is based on the idea of shutting off energy consuming devices during a period of power shortage, if their operation is not necessary, and optionally to turn on such energy consuming devices during periods of excess power, if energy may be stored in them, especially when energy may be stored as some physical parameter or variable, being a part of the operation of the energy consuming devices, such as the temperature of a freezer.

Abstract translation: 本发明涉及一种减少由于波纹而引起的能量损失的方法和系统，特别是在电力网上，波纹是短期电力短缺或过剩功率。 该方法基于在电力短缺期间关闭能量消耗装置的想法，如果其不需要操作，并且可选地在多余功率期间打开这种能量消耗装置，如果能量可以存储在其中， 特别是当能量可以作为某些物理参数或变量存储时，作为能量消耗装置的操作的一部分，例如冷冻器的温度。
