Described is, among other things, a method and an apparatus for control of a cooling device. The cooling device comprise a circuit in which a refrigerant fluid is circulated in a fluid path where the circuit comprises a compressor and a condenser provided down streams the compressor. A fluid expansion device is provided down streams the condenser and an evaporator is provided between the fluid expansion device and the compressor. The circuit further comprises a valve provided in the fluid path between the condenser and the fluid expansion device. The method comprises to during an on-cycle of the compressor controlling the valve opening to provide a variable fluid mass flow of the refrigerant fluid circulated in the circuit where the valve opening is controlled to decrease during the on-cycle of the compressor.

Control method for a cooling device

A refrigerator apparatus having a compressor, a condenser, an evaporator, and a valve interconnected in the flow from the condenser to the evaporator. The valve is operatively controlled to a first, open, state and to a second, closed, state by a controller. The controller is configured to the valve to operate in accordance with at least one of: opening the valve a time period of 0-180 seconds before the compressor is switched to an on-phase; and closing the valve before the compressor is switched to an off-phase.

Cooling system and a method for control thereof

A refrigerator () comprising a refrigeration system () being at least intermittently flowed through by a refrigerant and a first compartment () cooled by the refrigeration system () is provided. System components comprise a single compressor (), a condenser (), a first expansion arrangement (), a second expansion arrangement (), a first evaporator (), and a sub-cooler () comprising a first refrigerant channel () and a second refrigerant channel (). The refrigeration system () comprises a first conduit path () and a second conduit path (), the first conduit path () comprising the first refrigerant channel (), the first expansion arrangement (), and the first evaporator (), and the second conduit path () comprising the second expansion arrangement () and the second refrigerant channel (). A flow control device () for alternately directing refrigerant through the first conduit path () and the second conduit path () is arranged in the refrigeration system (). Further a method of controlling a refrigerator is provided.

Refrigerator having a refrigeration system with first and second conduit paths

An in-line drink dispensing system () for dispensing liquid such as water or other beverage. The system comprises a pump () in fluid connection with the system so that the pump can create a flow in the system and based on the current that the pump uses during operation a value can be determined and used for analyzing one or more statuses of the system.
