(2) if temperature controller adhesive, compressor, with 80HZ operation 7 minutes, 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 move until temperature controller disconnects with 80HZ, circulate successively three cycles, guarantee that spin manifold temperature can reach refrigeration truly;
The 3rd step: according to the loading rate of refrigerator, adjust the operating frequency of compressor, with the best operating point of software algorithm Automatic-searching compressor;
(1) keep frequency conversion refrigerator to move with 80HZ, and start timing,
(2) detect the variation of refrigerator inverter load electric current:
If load current does not change, compressor moves with original frequency;
If changing appears in load current, according to the running frequency of loading rate change compressor;
(3) detect the attracting state of temperature controller:
If temperature controller adhesive, carries out the A control program of the operation (4) of this step;
If temperature controller disconnects, carry out 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, 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, the operation of compressor forced stoppage is 15 minutes, timing zero clearing, and compressor increases 20HZ in the running frequency in next cycle, records the running time in next cycle;
With this, carry out three circulations more than cycle, if continuous three periodic duties of freezer compressor occur in one-period that surpass 4 hours running time, point out fault, refrigerator control system re-powers and resumes operation;
(4) action of B control program is as follows:
A. detect after temperature controller disconnection, compressor is out of service, operation timing zero clearing;
B. again detect the attracting state of temperature controller:
If temperature controller disconnects, control compressor out of service, operation timing zero clearing;
If temperature controller adhesive detects continuous three the above loop cycle of temperature controller again:
If 1.. in loop detection process, there is off-state in temperature controller, returns to this step operation (1);
If 2.. in loop detection process, temperature controller, all in attracting state, detects the running time of compressor:
If compressor in continuous circulation running, occurs that once surpass 4 hours running time in one-period, control compressor forced stoppage;
If compressor is in continuous circulation running, be all less than 4 hours the running time in each cycle, controls compressor with 54HZ low cruise, turns back to the operation (2) of this step simultaneously.
The present invention has realized frequency conversion refrigerator start fast-refrigerating, reach the object of food fresh keeping, and the variation of load factor while working according to frequency conversion refrigerator, controls freezer compressor and turns round in the most energy-conservation mode, reaches the beneficial effect of the required refrigerating capacity of adjustment refrigerator inside.
