Cooling apparatus and method

Method for controlling the temperature in an absorption refrigerator (1), wherein said refrigerator includes

• a cabinet having outer walls (2, 3, 4, 5, 6) and at least one door (7, 8) encasing a low temperature storage compartment (9) and a higher temperature storage compartment (10), said compartments being separated by a partition wall (11),
• an absorption refrigerating system including an evaporator tube (20) in which a refrigeration medium flows from an upstream end to a downstream end of the evaporator tube, and which evaporator tube comprises a first tube section (21) which is arranged to absorb heat from the low temperature compartment, and at least a second tube section (22), which is arranged to absorb heat from the higher temperature compartment,
• a battery arranged to supply power to said absorption refrigerating system during at least part of the operating time for said absorption refrigerator, and
• a heater arranged in said higher temperature storage compartment provided to apply heat to said higher temperature compartment,
• characterized in the steps of,
• detecting if said battery is currently charged or if AC-power is available,
• setting freezer control values to a first set of freezer control values if said battery is charged or if AC-power is available, and
• setting said freezer control values to a second set of freezer control values if said battery is not charged or if AC-power is not available, wherein
• at least one of the values in said second set of freezer control values is higher than both values in said first set of freezer control values.

• a heater arranged in said higher temperature storage compartment provided to apply heat to said higher temperature compartment,
• characterized in the steps of,
• starting said absorption refrigerating system if either
• the temperature in said higher temperature compartment is above said specified temperature range or
• the temperature in said lower temperature compartment is above a higher freezer temperature threshold, and
• stopping said absorption refrigerating system if both
• the temperature in said higher temperature compartment is below said specified temperature range, and
• the temperature in said lower temperature compartment is below a lower freezer temperature threshold.
