Common questions about Constant Temperature and Humidity Chiller:

The constant temperature bath has been in use for over a year and everything has been working fine. But now, the cooling speed seems to be getting slower and slower, especially when the temperature is higher.

The reason is that the use of a constant temperature bath is actually very simple, but regular maintenance and care still cannot be ignored. Many problems that seem like malfunctions are actually caused by the lack of regular maintenance and care. Since both the electrical power of the constant temperature bath itself and the heat carried away by the refrigerant from the load need to be discharged from the radiator at the front ventilation cover, if the front ventilation cover is covered with dust or other impurities, it will hinder the dissipation of these heats, and the cooling effect will be greatly reduced. Generally speaking, under normal usage conditions, a decrease in cooling capacity is basically caused by poor ventilation and heat dissipation or excessively high ambient temperature.

2. The constant temperature bath used to work fine, but now it's found that the noise is much louder than before. What could be the reason for this?

The reason: As mentioned earlier, the daily maintenance work of the constant temperature bath is also related to this issue. Everyone knows that water contains a small amount of impurities. Even pure distilled water cannot guarantee that there are no impurities at all after being added to the water tank. For a constant temperature bath, the general temperature is set at 20℃, but this temperature is also particularly suitable for the growth and reproduction of microorganisms. Over time, these microorganisms will clog the filter in the waterway, resulting in poor water return and causing the water pump to make a lot of noise. Sometimes these microorganisms attach to the surface of the heat exchanger, causing the heat transfer effect of the heat exchanger to deteriorate and the cooling capacity to decrease. Therefore, it is essential to strictly follow the requirements in the manual to carry out daily maintenance work, clean the inner tank regularly, and keep the tank dry if it is not used for a long time.

It seems that there is a leak in the constant temperature bath. Sometimes there are a few drops on the ground in a short while. Could there be a leak somewhere in the water? Reason: Generally speaking, during normal use, there will be no leakage in the waterway. When the ambient temperature is relatively high and the relative humidity in the air is too large, the water vapor at the water pump, water pipe joints and external water pipe connections in the water circuit of the constant temperature bath is prone to condense and produce dew. When it accumulates too much, it will drip onto the ground. There is no need to worry that there is a leakage in the water circuit. If you are very concerned about this, turning on the air conditioner to lower the room temperature or dehumidify can prevent the formation of dew.
