There are problems in the high and low temperature test chambers in the laboratory. We must first learn to determine the reasons for these abnormal conditions. Our usual methods of judgment are: seeing, listening, touching, measuring, and analyzing. First, look at: carefully observe the working conditions of the high and low temperature experimental box components, focusing on the three parts of the refrigeration system, electrical system, and circulation system to determine whether they work properly. Second, listen: power on and listen to the high and low temperature experimental box compressor running sound is normal, with or without abnormal sound, fan operation with or without noise, noise is too large. Third, touch: Touch the relevant parts of the high and low temperature test chamber to feel the cold, heat, vibration, etc., to help determine the nature and location of the fault. Under normal conditions, the temperature of the condenser gradually decreases from top to bottom, and the temperature of the lower part is slightly higher than the ambient temperature. If the entire condenser is not hot or the upper part is slightly warm, or if it is hot, but the temperature of the two adjacent pipes is significantly different, it is abnormal. Fourth, measurement: In order to accurately determine the nature and location of the fault, it is often necessary to use instruments and meters to check the performance parameters and status of the high and low temperature test chamber. If using a leak detector to check for refrigerant leakage; use a multimeter to measure the power supply voltage, the ground current and operating current of each terminal meet the requirements. V. Analysis: Most of the results obtained by the above-mentioned several inspection methods can only reflect a certain partial state. The parts of the high and low temperature test chambers are connected and interact with each other. There may be multiple reasons for a fault phenomenon, and one cause may also cause multiple faults. Therefore, a comprehensive comparative analysis of local factors is required to comprehensively and accurately determine the nature and location of the fault.
