How does portable fridge work?
Portable freezer is characterized by not using electric energy, but chemical energy, is small volume, lightweight, can be moved, convenient to carry, and portable refrigerator by the refrigerator insulation shell, refrigerant storage bag, and chemical refrigerant composition.
Portable refrigerator cooling can be used with the opening, the cooling duration can be decided by adding the amount of chemical energy, and the temperature inside the box can be reduced to zero degrees Celsius to -10 degrees Celsius, suitable for high-temperature work in the field, when it is hot, long-distance transportation of goods to keep fresh, the sick body cooling first aid.

How to extend the life of portable fridge in lab?
In the laboratory, portable fridge for low-temperature equipment is suitable for universities, research institutes, institutions, biological and pharmaceutical chemical enterprises, hospitals, and other preservation of laboratory reagents and consumables, drugs, biological products, etc.
Portable refrigerator maintenance and maintenance for the extension of its life and normal use is particularly important, if the temperature control is not accurate often leads to the preservation of objects damaged, and the experimental results are caused by a great impact, thus affecting the normal conduct of research work.
Therefore, in the use of portable refrigerators, such as the discovery of common failures, please promptly eliminate them, the following are the use of laboratory refrigerators' common failures and methods of elimination.
| Common faults and causes | Removal method |
When the power is turned on, the air switch of the main power supply of the portable refrigerator is automatically disconnected.
This fault is generally caused by the instability of the power supply because the first stage starts first, so the damage is usually in the first stage | Check if the first level of the refrigeration system compressor is damaged, if damaged will cause a short circuit, causing power protection. Can replace parts, if there are no original parts, can be measured by the replacement of the refrigerator compressor of equivalent power, the pipeline will be welded, after pressure checks the pipeline airtight vacuum and add R-12 Freon 23.00z, and then turn on the machine to test whether normal. |
| Due to detecting the temperature of the thermistor damage portable fridge box temperature has not reached the set temperature and has stopped working. | Although the set temperature is not reached in the mini-fridge, the panel shows that the temperature has reached the set temperature. This is due to damage to the thermistor that detects the temperature and requires replacement parts. If the original parts are not available, a new set of temperature control systems can be installed to eliminate the fault. |
| Due to the compressor leakage caused by the whole box with electricity, the refrigerator cooling effect is reduced, and people touch the metal part of the box with an electric shock feeling | Use a multimeter to measure the refrigerator leakage, using the segmentation method to check. In to high-temperature level compressor alone energized operation, check whether it is due to the compressor leakage caused by the whole case with electricity. Static test compressor terminals, pay attention to observing the motor winding inside the lead plug part, if there are traces of firing with the case, indicating the leakage of electricity. |
| Portable refrigerator alarm activation alarm | Check that the power supply is not faulty or that the plug is not pulled out of the socket; check that the internal thermometer is not out of the proper range, in which case the items placed will heat up the refrigerator and trigger the alarm; check that too many items are placed at once. |
| Inadequate cooling of ultra-low temperature portable refrigerator | Check if the floor is solid; if there are objects touching the back of the refrigerator; check if the refrigerant is missing |
Precautions for using portable fridge
a. In the laboratory, the
samples and quality control products put into the portable refrigerator must be sealed and kept.
b. Portable fridge box sometimes will have dew, this is a normal phenomenon, not that the product is faulty, but the use of high temperature and wet environment, please open the lid, so that the body is down, from the front of the body drainage, but also available dry rag will be wiped clean dew can be.
c. The portable refrigerator is in maintenance, please be sure to unplug the power, and do not wash it with water or water beads, otherwise, there is the risk of electric shock, and short circuit.
d. Portable freezers according to the use of the environment sometimes dew, and portable refrigerators such as not wiping dry placed, there will be moldy phenomenon and odor generation.
e. A portable refrigerator can not use alcohol, Tiana water, in addition to light liquid to wipe, otherwise, it will be discolored.
f. In the use of the process, the door does not open too often, try to reduce the number of times to open the door, and shorten the time to open the door, to reduce the leakage of gas inside the box, to save electricity.
g. Should keep the small ice The area around the box body clean and clean, to avoid fluttering and being inhaled at the condenser, affecting the refrigeration effect.
