1. A refrigerator comprising evaporator, cyclone separator, and supply pipe for supplying liquid from condensator to evaporator, the evaporator being connected to the upper part of the cyclone separator via a delivery pipe, characterised in that -the cyclone separator is disposed at a distance above the evaporator, -the lower part of the cyclone separator, which is a liquid collecting compartment, is connected to the evaporator via a down pipe, -the cyclone separator comprises a level sensor for registering liquid level in the collecting compartment of the cyclone separator, -the supply duct is connected with a valve, and -the level sensor form a part of controlling the valve for maintaining an approximately constant liquid level in the cyclone separator. 2. A refrigerator according to claim 1, characterised in that the supply pipe from the condensator discharges tangentially into the cyclone separator. 3. A refrigerator according to claim 1, characterised in that the supply pipe from the condensator to the evaporator discharges into the down pipe, and that the transition between this supply pipe and the down pipe is formed as an ejector for increased circulation of the liquid in the refrigerator. 4. A refrigerator according to any preceding claim, characterised in that the level sensor is disposed 50-100 mm, preferably 66 mm, above the evaporator. 5. A refrigerator according to any preceding claim, characterised in that the level sensor is a vibration level switch for liquids. 6. A refrigerator according to any preceding claim, characterised in that the refrigerator is an ice cream machine.
