Abstract: 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.

Abstract: 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.

Abstract: A refrigerator (2) comprising a refrigeration system (4) being at least intermittently flowed through by a refrigerant and a first compartment (6) cooled by the refrigeration system (4) is provided. System components comprise a single compressor (10), a condenser (12), a first expansion arrangement (14), a second expansion arrangement (16), a first evaporator (18), and a sub-cooler (20) comprising a first refrigerant channel (22) and a second refrigerant channel (24). The refrigeration system (4) comprises a first conduit path (26) and a second conduit path (28), the first conduit path (26) comprising the first refrigerant channel (22), the first expansion arrangement (14), and the first evaporator (18), and the second conduit path (28) comprising the second expansion arrangement (16) and the second refrigerant channel (24). A flow control device (30) for alternately directing refrigerant through the first conduit path (26) and the second conduit path (28) is arranged in the refrigeration system (4).

Abstract: An in-line drink dispensing system (1,16,17) for dispensing liquid such as water or other beverage. The system comprises a pump (6) 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.

Abstract: A refrigeration system 4 controlled by a control system 26, wherein the refrigeration system 4 comprises: an evaporator 8, a compressor 10, a condenser 12, and an expansion arrangement 15. The control system 26 is adapted: to establish a momentary cooling requirement based on the differential between a set-point temperature and an actual temperature averaged over time, to form a requirement variable relating to the momentary cooling requirement, to fix a first duration during which the compressor is switched on and a second duration during which the compressor is switched off, and to switch on and to switch off the compressor according to the first and second durations. The refrigeration system 4 comprises a first shut-off valve 20. The control system 4 is adapted: to close the first shut-off valve 20 in connection with switching off the compressor 10, and to open the first shut-off valve 20 in connection with switching on the compressor 10.

Abstract: A refrigerator (2) comprising a refrigeration system (4) a compartment (6) cooled by the refrigeration system (4) is provided. The refrigeration system (4) comprises a compressor (10), a condenser (12), a first expansion arrangement (14), an accumulator (16) for gaseous and liquid refrigerant, a second expansion arrangement (18), and an evaporator (20). The refrigeration system (4) comprises a first conduit path (22) and a second conduit path (24), the first and second conduit paths (22, 24) extending in parallel from the accumulator (16) towards the compressor (10). The compressor (10) is the only compressor of the refrigeration system (4) and the compressor (10) is a single stage compressor. A flow control device (26) is arranged in the conduit system (8) for alternately directing refrigerant through the first conduit path (22) and the second conduit path (24).
