Abstract
A method for determining wire connections in a vapor compression system (1) is disclosed. The vapor 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 vapor 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 vapor 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 vapor compression system (1), in response to said changed operational setting, comparing the measured variable values to expected behavior 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 installin…
