Economic high and low temperature test machine cooling slow many people subconsciously think is the quality of equipment problems, in fact, it is not.
equipment before the factory are subject to strict acceptance, the general chance of quality problems is very small, then lead to the test box cooling slowly in the end what is it?Generally speaking, lead to a small rapid temperature change test box cooling slowly, after excluding quality problems, there are only the following cases: First, the equipment condenser on the ash accumulation is serious (more common phenomenon) due to the equipment for a long time without maintenance, resulting in the equipment condenser on the ash accumulation is serious, thus affecting the cooling effect.
therefore requires regular cleaning of the equipment condenser.
, refrigeration system factors Refrigeration system will be blocked, if the refrigeration system for a long time blockage, the damage to the equipment is still very large, serious will lead to compressor damage.
3. Refrigerant factor Refrigerant leakage, and refrigerant can be called the blood of the refrigeration system, if there is a leak in any part of the refrigeration system refrigerant leakage, less cooling capacity, will naturally affect the cooling of the equipment slower.
4, the test product load is large in the test needs to be powered on the test, generally speaking, as long as the test product heat within 300W for the rapid temperature change test box is not much impact, if the heat over the general assembly makes the temperature in the box drop slowly, in a short period of time difficult to reach the set temperature.
5. The use of temperature factors Whether in the quotation contract, or in the delivery training, we will emphasize the ambient temperature of the equipment, when working at the temperature of celsius, the ambient temperature should be 25 degrees, the laboratory should be ventilated, to maintain air circulation, but some customers may not care.
if the equipment is placed at an ambient temperature above 35 degrees C and the laboratory is relatively closed, it will inevitably lead to slow cooling speed, and long-term operation of the equipment at high temperatures will lead to aging damage to refrigeration systems and electrical components.
6. The ambient temperature is too high If the ambient temperature is too high when using a small rapid temperature change test chamber, for example, in summer, room temperature is around 36 degrees C, if there are other equipment around, the temperature is even higher than 36 degrees C, which will lead to rapid changes in temperature and slow cooling of the test chamber.
this case, it is mainly to reduce the ambient temperature, such as laboratory air conditioning.
if laboratory conditions are limited, only the equipment bezel can be turned on and the fan can be cooled.
if these problems are eliminated, or do not solve your needs, it is recommended that you consult the manufacturer or local repair point, do not mess up so as not to cause big problems.
