What should I do if the water circuit of the high and low temperature damp heat test chamber is not smooth?
Dehumidification system of atmospheric pressure humidity test chamber. The monitoring system begins to monitor the humidity level. If the humidity exceeds the specified level, the dehumidification system will start. Moisture is discharged from the workshop and cooled to the dew point through an evaporator. Release water molecules from the air to dehumidify.
The refrigeration system of the high and low temperature wet heat test chamber is similar to that of a household refrigerator. Set temperature and humidity parameters after startup. Firstly, check the temperature inside the box. When the humidity exceeds the set temperature of the system, the high and low temperature humidity test box will start the refrigeration system. Refrigerators generally use mechanical refrigeration and liquid nitrogen refrigeration. Including compressor, capacitor, evaporator, and throttling device. After filtration, the high-pressure fluid refrigeration system enters the evaporator through an expansion throttle valve to reduce pressure. The working fluid absorbs heat from the air through the evaporator and evaporates into gas. The air refrigerant is sucked in through the compressor, forming a high-temperature and high-pressure gas that enters the air condenser. During heat exchange, the condenser absorbs heat, transforming the gaseous refrigerant into a high-pressure liquid. Repeat the cycle to achieve a cooling effect. The control system continuously monitors the temperature throughout the entire testing process. The cooling system stops working after heating to the set temperature. If the temperature exceeds the specified temperature, the cooling system will restart.
The high and low temperature wet heat test chamber has been widely used in various fields, but with the increasing number of manufacturers using it, minor faults are also gradually increasing, so the loss of the high and low temperature alternating test chamber is increasing. To avoid the movement of high and low temperature testing equipment, unnecessary damage or refrigerant leakage, it must be carried out under the guidance of technical personnel.
If the waterway is not smooth, the scale on the humidifier can easily dry it out, which may damage the humidifier. Therefore, it is necessary to regularly clean the pipes and humidifier. The instrument should be placed in a relatively mild environment, with an ambient temperature and humidity generally ranging from 5 ℃ to 30 ℃ ≤ 85% RH. If this condition is not met, air conditioning or cooling towers should be installed to ensure the service life of the compressor and the entire machine. The test results show that the intermittent testing chamber is regularly cleaned during high temperature intervals to ensure its good ventilation and heat transfer performance. And ensure the corresponding flow rate and regularly clean the condenser descaling to achieve continuous heat transfer performance.
