Precautions for use of artificial climate chamber:
1, the use of artificial climate box power: 220v, 50hz
2. The artificial climate chamber should use clean water (distilled water or purified water) below 40 °c. Hard water and dirty water such as tap water should never be used for long-term use.
3. When the water tank of the artificial climate box is separated from the base, the water on the base must be inverted, otherwise it will not produce steam.
4, the water tank of the artificial climate tank with water cover and spring valve (water outlet) should not leak water to avoid damage to the electrical appliances in the base, or cause no steam.
5. The ambient temperature of the artificial climate chamber should be between 1-45 °c.
6. The artificial climate chamber should be placed horizontally on the ground, and the plastic hose should not be folded flat or drooping.
7. The artificial climate chamber needs to be cleaned after a period of use, but it is not possible to scratch the transducer with a hard object.
8. The artificial climate box should be washed, dried and dried before storage.
9, there is high pressure in the artificial climate box, non-professionals should not open the device inside the base.
Keep these precautions in mind to extend the life of the artificial climate chamber.
Overhaul of faults in artificial climate chamber refrigeration system:
If the artificial climate box is energized, the voltage machine works normally, but the artificial climate box cannot be cooled, or after the exhaust pipe is removed,
When the return air pipe press can be normally exhausted, it can generally be judged that its refrigeration system has failed. According to the above characteristics, it can be determined,
If the failure of the artificial climate tank refrigeration system is the system leakage type, the following methods can be used when troubleshooting:
Step 1: First check the system with a nitrogen pressure to determine if the leak occurred at the high pressure. After a series of inspections, it was finally determined that the leak was the press exhaust pipe and the right
The side condenser is connected between the tubes. At this point, first cut off the connecting pipe, and then weld the connecting pipe of the condenser. After the welding is completed, you can start vacuuming and adding ice.
After turning on the power of the artificial climate chamber, open the switch to see if it is cooling. After four hours of cooling, the temperature of the freezer compartment reached -13 ° C, and the temperature of the refrigerator compartment reached 8 ° C.
After about ten hours of continuous cooling, the temperature at the time of refrigerating fell to 3 ° C, the temperature of the freezer began to rise and continued to rise, while the capillary of the refrigerating chamber continued to work without conversion.
Step 2: Assume that the cause of the failure is ice blockage in the capillary of the freezer compartment, causing the refrigeration system to malfunction. The evaporators of the freezer compartment and the refrigerator compartment can be separately flushed with nitrogen.
And replace a new capillary of the same specification, after the replacement is completed, inject 15ml of methanol into the system, and then evacuate. After three hours, re-add the ice and try again.
machine. If it still cannot be cooled, stop it immediately, and use the automatic detection function to detect the solenoid valve. Also check the capillary connection status of the freezing chamber to determine whether it is connected.
Pick up correctly.
Step 3: After the refrigerator compartment is closed, the freezer compartment evaporator is operated separately. If it can work normally and there is no sign of rising when the temperature drops to -15 °C, it can be excluded.
The possibility of evaporator capillary blockage.
Step 4: Assume that the cause of the malfunction is that the solenoid valve is stuck and the conversion function is out of order, replace a new solenoid valve, then vacuum, add the ice and retest the machine, if the system is still
If it does not work properly, you can rule out the possibility of the solenoid valve being stuck.
Step 5: Check the four sensors and see if the resistance is about 2.5KΩ. If yes, the sensor is normal.
However, considering the influence of temperature on the resistance of the sensor, the four sensors should be replaced in sequence, and if the fault is not eliminated, the possibility of abnormality of the sensor is excluded.
Step 6: Study the operation of the control part, check the working condition of the computer board and the operation display board, whether there is program confusion and system failure, and replace the operation display board.
And computer board,
See if the system is back to normal.
Step 7: After the overhaul, if the above parts are all normal, check whether the connecting line in the artificial climate chamber is abnormal, and whether it is subjected to electromagnetic interference and malfunction. can
Dig up the foam first,
Observe the condition of the connecting line. If the foam on the side of the refrigerating compartment is found to be wetted by moisture, causing moisture between the sensor and the connecting line, causing the line to age, the line can be judged.
Aging and insulation failure causes resistance changes,
Affected the normal operation of the computer version, a system failure occurred. At this point, replace the new sensor cable, re-foam, and test the machine, the artificial climate box returns to normal, so
