COOLING DEVICE AND METHOD FOR CONTROLLING A COOLING DEVICE

摘要

THE INVENTION RELATES TO A COOLING DEVICE COMPRISING AT LEAST ONE REGENERATIVELY OPERATED PRIMARY COOLING CIRCUIT IN PARTICULAR A SOLAR POWERED COOLING CIRCUIT WHEREIN THE COOLING CIRCUIT HAS AT LEAST ONE COMPRESSOR AT LEAST ONE CONDENSER AT LEAST ONE EVAPORATOR AT LEAST ONE COOLING SPACE AT LEAST ONE TEMPERATURE SENSOR FOR MEASURING THE COOLING SPACE TEMPERATURE (T) IN THE COOLING SPACE AND A CONTROLLER. A DESIRED TEMPERATURE VALUE (SET) OF THE COOLING SPACE AND A COMPARISON TEMPERATURE VALUE (T) CAN BE STORED IN THE CONTROLLER. THE INVENTION IS CHARACTERISED IN THAT THE COOLING OF THE COOLING SPACE CAN BE INTERRUPTED BY THE CONTROLLER AND THE COMPARISON TEMPERATURE VALUE (T) CAN BE CHANGED BY THE CONTROLLER DEPENDING UPON THE TIME AND/OR THE COOLING SPACE TEMPERATURE (T). THE INVENTION FURTHER RELATES TO A METHOD FOR CONTROLLING A COOLING DEVICE WHICH IS CHARACTERISED IN THAT THE COMPARISON TEMPERATURE VALUE (T) CORRESPONDS TO THE DESIRED TEMPERATURE VALUE (SET) WHEN THE CONTROLLER IS SWITCHED ON AND THE COOLING OF THE COOLING SPACE IS INTERRUPTED WHEN THE ACTUAL COOLING SPACE TEMPERATURE (T) HAS REACHED THE COMPARISON TEMPERATURE VALUE (T). IN THIS CONNECTION THE COMPARISON TEMPERATURE VALUE (T) IS REDUCED AFTER A PREDETERMINED TIME PERIOD (T) BY A STORED CORRECTION VALUE (D) SO LONG AS THE ACTUAL COOLING SPACE TEMPERATURE (T) HAS NOT REACHED THE COMPARISON TEMPERATURE VALUE (T) WITHIN THE PREDETERMINED TIME PERIOD (T).
