摘要： A method for determining wire connections in a vapour compression system (1) is disclosed. The vapour compression system comprises a compressor, a condenser, an expansion device (2) and an evaporator (3) being fluidly interconnected in a refrigerant path, and two or more sensor devices (7, 8, 9, 10, 11) arranged for measuring variables which are relevant for the operation of the vapour compression system (1). The method comprises the steps of changing an operational setting, e.g. an opening degree of the expansion device (2) for the vapour compression system (1), monitoring variable values, such as temperatures, being measured by at least two sensor devices (7, 8, 9, 10, 11), e.g. arranged at various positions of the vapour compression system (1), in response to said changed operational setting, comparing the measured variable values to expected behaviour of at least one variable measured by a sensor device (7, 8, 9, 10, 11) in response to said changed operational setting, and based on the comparing step, determining at least one wire connection of the vapour compression system (1). The method allows correct wire connections to be established without any special effort from the installing personnel, and without requiring rewiring of the system.

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： A method for controlling a supply of refrigerant to an evaporator (5) of a vapour compression system (1), such as a refrigeration system, an air condition system or a heat pump, is disclosed. The vapour compression system (1) comprises an evaporator (5), a compressor (2), a condenser (3) and an expansion device (4) arranged in a refrigerant circuit. The method comprises the steps of: Actuating a component, such as an expansion valve (4), a fan or a compressor (2), of the vapour compression system (1) in such a manner that a dry zone in the evaporator (5) is changed; measuring a temperature signal representing a temperature of refrigerant leaving the evaporator (5); analysing the measured temperature signal, e.g. including deriving a rate of change signal; determining a temperature value where a gain of a transfer function between the actuated component and the measured temperature drops from a maximum value to a minimum value, in a decreasing temperature direction; defining the determined temperature value as corresponding to a zero superheat (SH=0) value of refrigerant leaving the evaporator (5), and controlling a supply of refrigerant to the evaporator (5) in accordance with the defined SH=0 temperature value, and on the basis of the measured temperature signal. The method steps may be repeated at certain time intervals in order to provide updated determinations of the SH=0 temperature value. The method allows the SH=0 point to be determined purely on the basis of the measured temperature signal. Subsequently, the supply of refrigerant to the evaporator (5) can be controlled purely on the basis of the measured temperature signal.

摘要： A method for controlling a flow of refrigerant to an evaporator (1) arranged in a refrigeration system is disclosed. The refrigeration system further comprises an expansion valve (12) and a compressor, the expansion valve (12), the evaporator (1) and the compressor being arranged in a refrigerant flow path having refrigerant flowing therein. The method comprises the steps of increasing an opening degree of the expansion valve (12), thereby increasing a flow of refrigerant to the evaporator (1) sufficiently to substantially eliminate a dry zone (3) of the evaporator (1), decreasing the opening degree of the expansion valve (12) after a period of time has lapsed, and repeating the steps of increasing and decreasing the opening degree of the expansion valve (12). Thus, the opening degree of the expansion valve (12) is 'pulsated'. This causes the superheat value of refrigerant leaving the evaporator (1) to 'toggle' between a zero level and a low, but positive, level. Thereby the average superheat value of the refrigerant leaving the evaporator (1) is decreased, and the refrigeration capacity of the evaporator (1) is utilised more efficiently. Simultaneously, it is ensured that the amount of liquid refrigerant being allowed to pass through the evaporator (1) is kept sufficiently low to prevent damage to the compressor.

摘要： The invention provides a method of controlling a release of thermal energy in a building. The method comprises steps of defining a control criterion for the building, defining a set of climate variables which influence the release of thermal energy in the building, and defining for each climate variable, a climate signification index which defines the importance of that climate variable for the release of thermal energy in the building. Furthermore, the method comprises a step of receiving a set of predicted future climate variables, and subsequently a step of combining the climate signification indices and the predicted future climate variables to provide control instructions for release of an amount of thermal energy in the building to satisfy the control criterion. The invention further provides a comfort control system.
