The present invention concerns a cooling or heating system including at least a compressor (2), a condenser (4), an expansion apparatus (17A; 17B) and a vaporiser (20). The invention is characterised essentially in that in the condenser or in proximity to an outlet of the condenser (4) there is a control apparatus (7A; 7B) arranged to receive liquid from the condenser (4) and that includes an outlet to a condensate channel (9) and an intake (14; 30) to a signal channel (6, 10; 31), in that the condensate channel (9) is connected to the expansion apparatus (17A; 17B), in that there is means (8, 11, 18, 30, 34) to vaporize liquid that comes into the signal channel (6, 10; 31), in that means (12, 13) are connected to the signal channel (6, 10; 31) to control the expansion apparatus' (17A; 17B) opening process whereby said control is affected by the amount of liquid that is vaporised in the signal channel (6, 10; 31). The invention also concerns a method for controlling a cooling or heating system.
