"The high and low temperature test boxes are useless for several years, but the losses are particularly large." Actually, the wrong behavior that we frequently neglect in daily use is to accelerate the "aging" of high and low temperature test boxes. The technical director explains to you the several kinds of damage that the high and low temperature test box fears. High and low temperature test box door often switch. Routinely, the number of opening of the test chamber should be reduced as much as possible. Frequent opening of the door will increase the loss of cooling in the test chamber, affect the cooling effect, and increase the energy consumption. Deactivate high and low temperature test boxes for a long time. For some reason it is not necessary to do the test, the user will choose to let the test box “restâ€, but the manufacturer reminds, generally do not disable the test box for a long time, otherwise it will affect the life span, it should be running for one hour after a period of time, This can greatly increase the life and performance of the test chamber. High and low temperature test box power outlets are free to pull. When the test chamber is in normal use, the temperature in the test chamber reaches the set value, and the thermostat automatically cuts off the power supply. At this time, the high and low pressures in the refrigeration system are already balanced. For the compressor, the load is small and the motor is easy to operate normally. start up. If the power is forcibly cut off, the power supply is turned on immediately when there is a relatively high pressure difference in the refrigeration system. The high-voltage power difference causes the motor load to be too large and the starting current is 8 to 10 times the normal value, which is easy to over current. And the motor was burned. The manufacturer emphasized that after the test box is powered off, it should wait for 3 minutes. After the refrigeration system's high and low pressures reach equilibrium, the power supply is reconnected. High and low temperature test box cleaning agent is not properly selected. When cleaning the test box, in order to prevent damage to the outer coating of the box and the stainless steel parts in the box, do not use washing powder, decontamination powder, talcum powder, alkaline detergent, boiling water, brushes, etc. to clean the inspection box to prevent damage to the tank or Pipeline. First cut off the power supply, use a soft cloth dipped in water or dishwashing detergent, gently scrub, and then wipe the detergent with water. When cleaning, take care not to touch the electronic components in the inspection box to ensure the safety of electricity. After cleaning, plug in the power plug and check that the temperature controller is set to the correct position. Refrigerator is good once a year every year.
