What is the working principle of a variable frequency refrigerated dryer?

Variable frequency refrigerated dryer is a device that purifies, dries, and cools compressed air through components such as condenser and dehumidifier. This device can be widely used in various fields such as chemical engineering, food, electronics, textiles, refrigeration, etc. Its main characteristics are high efficiency and energy-saving advantages.

The working principle of a variable frequency refrigerated dryer can be simply divided into the following steps:

1. Compressed air is compressed into high-temperature and high-pressure gas through a compressor. Due to the large amount of water vapor contained in the compressed air, this water vapor is sucked in along with the air.

2. High temperature and high-pressure gases are cooled by a condenser, and the refrigerant in the condenser absorbs and carries away the moisture in the gas, thereby condensing the moisture in the air into water droplets. The temperature at this time is usually around 30 ℃.

3. The condensed gas enters the dehumidifier, where the desiccant adsorbs and absorbs moisture from the gas, thereby further removing moisture from the air.

4. The dried gas is cooled again through a condenser to achieve a lower dew point temperature. Dew point temperature refers to the temperature at which saturated moisture in a gas begins to condense.

5. The gas is filtered through the filter bag in the filter to remove other impurities and particulate matter, and outputs clean and dry compressed air.

It should be noted that the working effect of the variable frequency refrigerated dryer is directly related to the performance of components such as refrigerant, desiccant, and filter. Therefore, in the process of purchasing or using, it is necessary to choose the appropriate model and configuration according to the specific situation.

Overall, the working principle of a variable frequency refrigerated dryer is to cool, dehumidify, cool, and filter compressed air, and achieve drying effects through different component combinations. This device has advantages such as energy saving and stability, and is widely used in industrial production and manufacturing fields.
