Summary of the invention
For solving the deficiency that prior art exists, a kind of method of debugging the refrigerator refrigerant groundwater increment provided by the present invention is at the low-pressure end refrigerant emission of refrigerator; The suitable refrigerant perfused amount of refrigerator is confirmed in debugging; Save debug time, raise the efficiency, make refrigerator reach best cold-producing medium perfusion state.
For solving the problems of the technologies described above, the technical scheme that the present invention taked comprises: debug preceding preparation, manual modulation valve is connected to the low-pressure end of freezer compressor; One end of air bleeding valve connects together with manual modulation valve by the direction requirement, and an other end of air bleeding valve is equipped with capillary, and refrigerator is found time to pour into a certain amount of cold-producing medium; Groundwater increment, comprises evaporimeter gateway, compressor top, blast pipe, filter, muffler, refrigerating chamber, refrigerating chamber cloth temperature sensor for a numerical value of expection everywhere in the casing of refrigerator; Temperature controller is placed continuous running status; Simultaneously, prepare match with the volume of a cold-producing medium and water-filled graduated cylinder, and a water box that is used to hold graduated cylinder; Also fills with water, and just the capillary pipe end of air bleeding valve stretches into and is full of water and is inverted in the graduated cylinder of water box.
The stable operation step, closing refrigerator door, plug-in moves to stable, writes down each TEMP actuator temperature of the stable moment, power.
Comparison of statistics: recorded data is made a statistical form, and suitable groundwater increment is confirmed in contrast.
Comparison of statistics step, recorded data are made a statistical form, and suitable groundwater increment is confirmed in contrast.
Preparation process before the above-mentioned debugging is found time to pour into into than the expection groundwater increment and is manyed the cold-producing medium of 10-15g.
It is 32 ℃ or 30 ℃ that preparation process refrigerator before the above-mentioned debugging is placed environment.
Need open the door balance 12 hours of refrigerator in the preparation process before the above-mentioned debugging.
In the above-mentioned step of refrigerant emission one by one, refrigerator needs after outage surpasses 10 minutes, just can carry out the cold-producing medium discharging again.
When above-mentioned cold-producing medium is R600a working medium, cold-producing medium one by one in the drain steps each refrigerant emission be 2-5g.
When above-mentioned cold-producing medium is R134a working medium working medium, cold-producing medium one by one in the drain steps each refrigerant emission be 20g.
In order to realize technical scheme of the present invention, the fit of parts is such:
1, manual modulation valve is connected to the low-pressure end of freezer compressor, finds time to pour into a certain amount of cold-producing medium;
2, the end with air bleeding valve connects together with manual modulation valve by the direction requirement;
3, graduated cylinder is placed in the basin, is full of water, be inverted;
4, the capillary pipe end with air bleeding valve stretches in the graduated cylinder.
Refrigerator refrigerant adjustment method of the present invention has following advantage and useful technique effect:
1, under the situation that the high-pressure side method for exhausting can't be realized, adopt new method can reach identical effect, needn't increase solder joint and valve;
Can be when 2, adopting valve as finding time to pour into frock.
3, can avoid when the high-pressure side exhaust, because system pressure is higher, the shortcoming of the gloomy valve of the Chinese not easy to plug.

The specific embodiment
Embodiment
The method of adjustment refrigerant perfused amount is such: at first, estimate the general suitable refrigerant perfused amount of a refrigerator.Then, find time to pour into into than the expection groundwater increment and many cold-producing medium (, can irritate 20g) of 10-15g more for R134a.Refrigerator is placed under 32 ℃ of (or 30 ℃) environment, in the evaporimeter gateway of refrigerator, compressor top, blast pipe, filter, muffler, refrigerating chamber, refrigerating chamber etc. locate the cloth temperature sensor, and temperature controller is placed continuous running status.Simultaneously, in test cabinet, put a water box, filled with water.Water box size is wanted to decontrol graduated cylinder, makes graduated cylinder can be full of water.Refrigerator open balance 12h.
Closing refrigerator door, plug-in moves to stable state, each TEMP actuator temperature, power during the stable operation of record refrigerator;
Discharge quantitative cold-producing medium one by one: with stable refrigerator outage, order is turned on manual modulation valve, air bleeding valve, and refrigerant gas can be discharged in the graduated cylinder through capillary; Note the refrigerant gas volume of discharging, confirm its quality, after exhaust finishes through the refrigerant gas volume of discharging; Orderly close-down air bleeding valve, manual modulation valve take off air bleeding valve, plug-in make refrigerator move to once more stable after; Cold-producing medium is discharged by above-mentioned steps once more, repeat repeatedly, and after each discharging; When refrigerator operates steadily, note each TEMP actuator temperature, the power of refrigerator corresponding under each groundwater increment; When [0022] cold-producing medium was R600a working medium, each refrigerant emission probably was 2-5g.When cold-producing medium is R134a working medium working medium, cold-producing medium one by one in the drain steps each refrigerant emission be 5-10g.Different according to the refrigerator volume size, the each capacity of the refrigerator that volume is bigger can be omited many.
After the exhaust, order is turn-offed air bleeding valve, manual modulation valve, takes off air bleeding valve.It is stable to let refrigerator move to once more, record data.By that analogy, after each discharging, note the temperature of each temperature sensor of refrigerator corresponding under each groundwater increment, power.These data are made a statistical form, and suitable groundwater increment is found out in contrast.
Be exemplified below:
