Regarding some related questions about constant temperature and humidity test chamber, this article provides relevant answers:
1. Question: Is it better to use an open cooling tower or a closed cooling tower for water cooling equipment?
Answer: In open cooling towers, the water quality is susceptible to environmental pollution and requires frequent cleaning and maintenance to avoid alarm shutdown during equipment operation;
In closed cooling towers, the medium is not contaminated and the equipment failure rate is low in the future, so it is recommended to use closed cooling towers;
2. Question: Can tap water be used for humidification in the humidity chamber?
Answer: No, pure water must be used, and the conductivity of the water should not exceed 20us/cm;
3. Question: How often should the filter element of a pure water machine be replaced?
answer:
First level: fiber filter: recommended replacement cycle is 3-6 months;
Second level: Compressed activated carbon filter element: Recommended replacement cycle is 6-9 months;
Level 3: Compressed activated carbon filter element: Recommended replacement cycle is 6-9 months;
Level 4: RO reverse osmosis membrane: the recommended replacement cycle is 12-24 months;
Level 5: Post-activated carbon: Recommended replacement cycle is 12 months;
4. Question: How often should the humidity cotton cloth be replaced?
Answer: Generally, it should be replaced every 45 days. If the water quality is poor and the humidity cotton cloth becomes yellow and hard, it needs to be replaced in advance;
5. Question: How often does the equipment need to be maintained?
Answer: Generally, major maintenance is done twice a year;
6. Question: Will the temperature and humidity of the equipment gradually become inaccurate?
Answer: Long-term use may cause deviations, and it is generally necessary to perform three-party measurement calibration and correction once a year;
7. Question: What refrigerant does the equipment use?
Answer: Generally there are two types, one is a single machine system, using 404A refrigerant, and the other is a cascade system, using 404A and R23 refrigerant.
8. Question: Can the door be opened while the equipment is in operation?
Answer: No
1) When the device opens the door during operation, moist air will enter, causing frost on the evaporator and causing the device to alarm;
2) Opening the door at high temperature can cause burns, and opening the door at low temperature can cause frostbite.
