Abstract (en)
[origin: EP1775533A2] The method involves determining a control value for a throttle body based on the deviation of actual overheating of a cooling agent from a reference-overheating, and detecting liquefier pressure. Evaporator pressure is measured, and a model comparing the cooling agent mass flow rate at an evaporator input with the mass flow rate at an evaporator output is formed. Another control value is evaluated from the evaporator and liquefier pressures and cooling circuit specific values. Third control value is determined by combining the two values and the body is adjusted to the third value. An independent claim is also included for a device for controlling a compression refrigerator.
