Definitions
- the compressor 14 is a variable-capacity compressor, ie, a compressor with a variable refrigerating capacity, and the regulation of the refrigerant medium flow in the circuit is carried out with the aid of valve means provided between the condenser 15 and the capillary tubes 16 and
- variable- capacity compressor 14 which is provided with its own automatic control logic system capable of autonomously selecting the operating speed (and, therefore, the required refrigerating capacity) thereof on the basis of a combination (eg. the arithmetical mean value) of the percentages of operation, or running time, of the two compartments of the refrigeration appliance and the ON-periods (or operating periods) of the same compartments, by privileging the one that requires the longest operating time,
- Figure 3 illustrates a diagram showing the demand of cold, ie. heat-extraction requirement versus temperature variations in the cold storage compartment and the freezing compartment (as indicated in abscissas and ordinates, respectively).
- the letters A-H indicate the operating ranges at the various speeds of the compressor (A indicates the slowest speed, H the fastest speed).
- the rectangles represent the adjustment or setting areas of the refrigeration appliance at different room temperatures (Ta),
- the algorithm of the automatic control logic of the compressor 14 may for instance be based on following operation data:
- a further element that enables a real energy saving effect to be obtained is constituted by the utilization of the pulse-controlled valves 18 and 19.
- the actuation of these valves enables the circuit to be closed in the OFF periods of the refrigeration appliance, thereby preventing hot refrigerant medium from passing from the condenser 15 to the evaporators 12 and 13.
- the valve 19 really enables the evaporators to be fed in a selective manner, in accordance with the demand for cold, ie. the heat-extraction requirements of the respective compartments of the refrigeration appliance.
- the differentiation in the flow-rate capacity of the capillary tubes 16 and 17 enhances the flexibility of the refrigerating circuit in view of delivering a refrigerating capacity that actually meets the thermal load of the appliance in connection with both the independent utilization of the two compartments and the different conditions of the same compartments (room temperature, thermostat settings, door openings, and the like).
