摘要： PURPOSE:To plan energy saving operation by forming the refrigerator so that the selection of a plurality of compressors different in volume allows detection of the opening of a throttle device and with this opening detecting signals compared with operating data of the previously input compressors, efficiency is given priority. CONSTITUTION:A detecting part 26 detects the openings of throttle devices 12, 13 and a detecting signal is output. This opening detecting signal is input in a control part 20 for operating and controlling a first and a second compressors 1, 2. A refrigerant circulating quantity is calculated therein. Since the selection of the compressors 1, 2 for cooling load from the refrigerant circulating quantity in some operating condition is performed, previously input respective operating data of the compressors 1, 2 are compared therewith. The most efficient compressor for the cooling load at its time is operated by an output signal generated in the control part 20. In other words the operation of the compressors 1, 2 corresponding to fluctuation of the cooling load is selected by operation efficiency priority.

摘要： PURPOSE:To make a fast reacting to a predetermined set pressure and further improve dynamic characteristic such as a reduction of a consumption power and a follow-up characteristic in respect to a variation of a cooling load by a method wherein a fuzzy estimation is carried out in response to a difference between a sensed pressure of refrigerant at a low pressure side and a set pressure and a coefficient of differentiation of the sensed pressure. CONSTITUTION:A pressure comparator 10 stores a comparator for comparing a pressure sensing signal from a low pressure sensing part 7 with a reference value set in response to a set pressure and generates a signal corresponding to a difference between the reference value and the pressure sensing signal. Similarly, a differential coefficient calculation part 11 receives a pressure sensing signal from a pressure sensing part 7, calculates a differential coefficient of a refrigerant pressure and generates a signal corresponding to a result of calculation. A fuzzy control part 12 may perform a fuzzy estimation and output a positive value in response to a signal from each of the pressure comparing part 10 and the differentiating coefficient calculation part 11. A frequency control part 13 may control an inverter 5 in response to a positive value from the fuzzy control part 11 and control its output frequency. With such an arrangement, it is possible to reach a set pressure immediately, to reduce a consumption power and thus to provide a freezer device having a better dynamic characteristic against a load variation.

摘要： PURPOSE:To enable a predetermined set pressure to be rapidly reached and contrive a lower power consumption and a better follow-up to variation in cooling load, by performing a fuzzy inference according to the difference between a detected refrigerant pressure and a preset pressure and to the differential coefficient of the detected pressure, and varying a membership function according to a system. CONSTITUTION:When a pressure detecting part 7 detects a refrigerant pressure and outputs a pressure detection signal. A pressure comparing part 10 compares the signal with a reference value set correspondingly to a predetermined set pressure, and generates a signal corresponding to the difference between the two. A differential coefficient calculating part 11, on receiving the signal from the detecting part 7, calculates the differential coefficient of the refrigerant pressure, and generates a signal corresponding to the calculated coefficient. A fuzzy controlling part 12 performs a fuzzy inference based on the signals from the comparing part 10 and the calculating part 11, and outputs a set value. According to the set value, a frequency controlling part 13 controls a time for varying the output frequency of an inverter 5 so that the predetermined set pressure is reached in a shorter time. A function correcting part 14 corrects the shape of a membership function in the fuzzy controlling part 12 so as to improve dynamic characteristics in response to variations in load, thereby optimizing the dynamic characteristics of a refrigerant system.
