(2) if temperature controller adhesive, compressor runs 7 minutes with 80HZ, starts refrigeration, then with 140HZ high-speed cruising, enters fast-refrigerating state, until temperature controller tripping;
(3) when the rising of refrigerator body internal temperature causes temperature controller adhesive, control compressor and run until temperature controller disconnects with 80HZ, circulate three cycles successively, guarantee that spin manifold temperature can reach refrigeration truly;
3rd step: according to the loading rate of refrigerator, the operating frequency of adjustment compressor, with the best operating point of software algorithm Automatic-searching compressor;
(1) keep frequency conversion refrigerator to run with 80HZ, and start timing,
(2) change of refrigerator inverter load electric current is detected:
If load current does not change, then compressor runs with original frequency;
If change appears in load current, then according to the running frequency of loading rate change compressor;
(3) attracting state of temperature controller is detected:
If temperature controller adhesive, then perform the A control program of the operation (4) of this step;
If temperature controller disconnects, then perform the B control program of the operation (4) of this step:
(4) action of A control program is as follows:
If a. the running time T in this cycle of compressor is less than 4 hours, then directly get back to the operation (2) of this step;
If b. the running time T in this cycle of compressor is more than or equal to 4 hours, then compressor forced stoppage 15 minutes, timing resets, and compressor increases 20HZ in the running frequency in next cycle, records the running time in next cycle;
Carry out the circulation in more than three cycles with this, if continuous three periodic duties of freezer compressor occur that in one-period, running time more than 4 hours, then points out fault, refrigerator control system re-powers and resumes operation;
(4) action of B control program is as follows:
A. after detecting that temperature controller disconnects, compressor is out of service, runs timing and resets;
B. the attracting state of temperature controller is again detected:
If temperature controller disconnects, then control compressor out of service, run timing and reset;
If temperature controller adhesive, then again the loop cycle of continuous more than three of temperature controller is detected:
If 1.. in loop detection process, there is off-state in temperature controller, then return this step operation (1);
If 2.. in loop detection process, temperature controller is all in attracting state, then detect the running time of compressor:
If compressor is in continuous circulation running, occur once in one-period running time more than 4 hours, then control compressor forced stoppage;
If compressor is in continuous circulation running, the running time in each cycle is all less than 4 hours, then control compressor with 54HZ low cruise, turn back to the operation (2) of this step simultaneously.
Present invention achieves frequency conversion refrigerator start fast-refrigerating, reach the object of food fresh keeping, and the change of load factor when working according to frequency conversion refrigerator, controls freezer compressor and operates in the most energy-conservation mode, reach the beneficial effect of the refrigerating capacity needed for adjustment refrigerator inside.
