    Abstract: A method for controlling a vapour compression system (1) during start-up is disclosed. The rate of change, ΔΤ 1 , of the temperature of refrigerant entering the evaporator (4), and the rate of change, ΔΤ 2 , of the temperature of refrigerant leaving the evaporator (4) are compared. Based on the comparing step, a refrigerant filling state of the evaporator (4) is determined. The opening degree (11) of the expansion device (3) is then controlled according to a first control strategy in the case that it is determined that the evaporator (4) is full or almost full, and according to a second control strategy in the case that it is determined that the evaporator (4) is not full. Thereby it is ensured that a maximum filling degree of the evaporator (4) is quickly reached, without risking that liquid refrigerant passes through the evaporator (4).

    Abstract: The invention discloses a controller for a vapour compression system for cooling a refrigerated space. The system comprises a circuit for circulation of a refrigerant between a compressor (2), a condenser (3), and an evaporator (4). An expansion valve (5) controls a flow of the refrigerant into the evaporator (4) and thereby cooling of the refrigerated space. The control system is adapted to control the expansion valve (5) based on a first temperature (Tl) in the circuit between the evaporator (4) and the compressor (2) and a second temperature (T2) determined in the refrigerated space.

    Abstract: A method for calibrating a temperature sensor (6) arranged in a vapour compression system (1) is disclosed. The opening degree (9) of an expansion device (3) is alternatingly increased and decreased. Simultaneously a temperature (10) of refrigerant entering the evaporator (4) and a temperature (11) of refrigerant leaving the evaporator (4) are monitored. For each cycle of the opening degree (9) of the expansion device (3), a maximum temperature, T 1, max , of refrigerant entering the evaporator, and a minimum temperature, T 2,min , of refrigerant leaving the evaporator are registered. A calibration value, ΔΤ 1 , is calculated as ΔΤ 1 = C-(T 2, min - T 1, max ) for each cycle, and a maximum calibration value, among the calculated values is selected. Finally, temperature measurements performed by the first temperature sensor (6) are adjusted by an amount defined by ΔT 1, max .

    Abstract: 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.
